A typical Android job description can ask for Kotlin, Compose, Coroutines, Jetpack, testing, CI/CD, and more. But you know, in interviews, you won’t be asked for separate skills altogether. A few questions about state management, architecture, concurrency, debugging, or a production issue can tell an interviewer much more than a long skills section on your resume.
The skills required for Android developer roles in India also depend on the codebase you walk into. At product companies and app studios, you may work with Kotlin and Java in the same project, while Compose gradually replaces older XML and RecyclerView screens. Knowing the newer stack doesn’t mean you can ignore the old one.
This Android developer skills list covers the areas interviewers tend to probe, along with the depth of understanding you should be ready to demonstrate when discussing your work.
What Android Developer Skills Actually Mean in 2026
When you’re mapping out the Android developer key skills to learn, then the first thing you should do is look into the different parts of development you’ll be working with. Kotlin and Jetpack Compose will cover the language and UI side of things, while application architecture will help you understand how to organise your code and separate responsibilities. You’ll then need to work with coroutines and Flow for asynchronous operations, ViewModels and repositories for managing application data, and tools such as Room, DataStore, and Retrofit for storing and retrieving that data. You should also spend time on the Android lifecycle, permissions, background work, testing, R8, and Play Console releases, since these are all part of building, testing, and shipping Android applications.

This Android developer skill set falls into three broad bands, and each one answers a slightly different question about what you should learn:
- Table stakes: Skills you’ll use in most Android roles: Kotlin, Jetpack Compose, Android components and lifecycle, coroutines, networking, local data, and testing. These are also the areas you’ll be expected to discuss in most interviews.
- Differentiators: Skills that show stronger practical understanding: application architecture, state management, Flow, dependency injection, performance, modularisation, accessibility, and advanced testing. You should be able to explain the choices you make in these areas.
- Emerging skills: Newer Android APIs, platform changes, UI and concurrency patterns, and tools for performance and app delivery. These are becoming relevant as Android development continues to change.
The depth expected from you depends on your experience and the Android role you’re targeting. A junior developer and a five-year Android engineer may need the same foundations, but they won’t be expected to demonstrate the same level of expertise across every area.

The Android Developer Skills Checklist
The table below outlines the core android developer technical skills across each tier, along with how you can demonstrate them.
| Tier | Skill | Why recruiters test it | How to evidence it | Where to learn it |
| Language | Kotlin | Modern Android code is Kotlin-heavy, and interviews go beyond syntax into null safety, sealed classes, and idiomatic patterns. | A project using idiomatic Kotlin rather than Java-style code. | Kotlin docs + Android Kotlin codelabs |
| Java + Gradle | You may need to maintain Java code and understand how the Android build works. | A mixed Kotlin/Java project with a clean Gradle setup | Android + Gradle docs | |
| UI | Jetpack Compose | Recruiters want to know whether you understand state, recomposition and side effects, not just how to build a screen. | A Compose app using state hoisting and appropriate state handling. | Compose docs + codelabs |
| XML, RecyclerView + Material 3 | Existing apps still use Views, while newer screens may use Compose and Material 3. | A project containing both a legacy View screen and a Compose screen. | Android Views + Material docs | |
| Accessibility + adaptive UI | Production interfaces need to work across screen sizes and accessibility settings. | Screens tested across screen sizes with accessibility support. | Android accessibility + adaptive UI docs | |
| Architecture | MVVM/MVI + ViewModel | Architecture questions reveal whether you can separate UI state, business logic, and data access. | A project with clear state and data boundaries. | Android architecture docs |
| Repository + Hilt + modularization | Larger applications need manageable dependencies and clear module boundaries. | A multi-module project using Hilt and repositories. | Android architecture docs | |
| Async | Coroutines + Flow | Android apps regularly perform network and database work asynchronously. | A project using structured concurrency, StateFlow and appropriate coroutine scopes. | Kotlin + Android docs |
| Data | Room + DataStore | Local persistence is common, and developers need to choose the right storage mechanism. | A project using Room for structured data and DataStore for preferences. | Android data docs + codelabs |
| Retrofit + OkHttp + Paging | Networked apps need reliable API handling and efficient loading of large datasets. | A paginated API-backed screen with error and loading states. | Android + library docs | |
| Offline-first sync | Connectivity failures and conflicting updates are real production problems. | A project with queued writes and a documented conflict strategy. | Android offline-first docs | |
| Platform | Lifecycle + state restoration | Configuration changes and process death can expose weak state management. | A screen that restores important state after recreation. | Android lifecycle docs |
| Permissions + background work | Android places strict limits on permissions and background execution. | A project using runtime permissions and WorkManager correctly. | Android platform docs | |
| Notifications, FCM + deep links | These features connect the app to system and external events. | A working notification, push and deep-link flow. | Android + Firebase docs | |
| Quality & Release | Testing | Recruiters need evidence that you can verify behaviour instead of relying only on manual testing. | Unit and UI tests covering important flows and failure cases. | Android testing docs |
| R8 + performance + Play Console + CI/CD | A production app needs more than a successful debug build. | A release build with R8, measured performance, Play Console release, and automated checks. | Android performance + Play Console docs | |
| Emerging | KMP + on-device ML + AI-assisted development | These areas are becoming more relevant but aren’t table stakes for every Android role yet. | A small working implementation with tests and documented limitations. | Official Kotlin + Android AI docs |
Practical tip: Run through the table and tick off what you can explain / can build/have shipped. Being able to explain a technology isn’t the same as implementing it, and neither is the same as having shipped and supported it.
Kotlin and Java: What Android Developers Should Know
Kotlin has been Google’s preferred language for Android since 2019, and current Android APIs, Jetpack libraries, samples, and codelabs are Kotlin-first. For most product-company Android roles, knowing only Java is now a liability. The reason is simple: new Android work is increasingly written in Kotlin, so teams need developers who can work comfortably in that codebase.
Java is still part of what you’ll encounter in Android development, particularly when you work with large Indian codebases in banks, telcos, and long-running consumer applications that have years of Java behind them. So while Kotlin should be your main language, you should also be able to read and work with Java and handle the transition when an existing part of the codebase needs to be migrated.
As you build your Kotlin skills, look beyond syntax and spend time with null safety and platform types, especially the !! trap that can appear when Kotlin interacts with Java. You should also know when data classes and sealed classes make sense for modelling state, and understand extension functions, scope functions, higher-order functions, and inline functions well enough to explain why you’re using them.
For Java Developers Moving to Kotlin
If your Java fundamentals are solid, you’ll find that a lot of what you know still applies when you move to Kotlin: the JVM, object-oriented programming, collections, and much of your Gradle experience carry over. You’ll need to adjust to a few important differences, though, particularly Kotlin’s type-level nullability and its approach to immutability. For asynchronous work, you’ll use coroutines instead of the thread-based patterns you may be used to in Java, and Kotlin does not have checked exceptions.
If you already have experience with Java, you can start working with Kotlin within a few weeks. The syntax is unlikely to take up most of that time; you’ll need more practice with the way Kotlin handles common programming tasks, particularly null safety, immutability, scope functions, and coroutines.
If you’re deciding which language to invest in beyond Android, see which languages employers are actually hiring for.
UI Skills: Jetpack Compose and XML
The android app developer skills you build around UI should cover both Jetpack Compose and XML, because you’re likely to encounter both in an Android codebase. A new screen may use Compose while an older checkout flow still relies on XML and RecyclerView, and teams usually keep working screens as they are rather than rewriting them just because Compose is now the preferred approach. So you should be able to build new interfaces with Compose, read and modify existing XML layouts, and work with RecyclerView when the codebase calls for it.
You should also know how Compose and Views work together. ComposeView lets you place a composable inside an XML layout, while AndroidView lets you use an existing Android View from Compose. You’ll often use this kind of interop when adding a new Compose screen to an existing application or gradually replacing older UI code.
Understanding State and Recomposition in Compose
With Compose, you need to understand the relationship between state and recomposition. Learn how state hoisting and unidirectional data flow decide where state belongs and how it moves through your UI, then understand what causes a composable to recompose and how unstable parameters can trigger unnecessary work. You’ll also need to know the difference between remember and rememberSaveable, and how LaunchedEffect and DisposableEffect behave when the composition changes. For LazyColumn, use stable keys so Compose can identify each item correctly when the list is updated.
Once these concepts are clear, add the practical parts of Compose to your learning: previews, Compose UI tests, and Material 3 theming. These are the areas you should be ready to explain in an interview too, particularly what causes recomposition and how you would avoid doing unnecessary work.
XML Skills You’ll Still Use in Android Development
You should still know how the older Android UI stack works, particularly if you’ll be working on an existing application. That means being able to work with RecyclerView, DiffUtil, ViewHolder reuse, ConstraintLayout, ViewBinding, fragment transactions, and the back stack.
For a 2026 job hunt, build your new portfolio work with Compose, but make sure you can also open an existing RecyclerView adapter and follow what it is doing. If you’re coming from web development, some of the state-to-UI ideas will feel familiar; you can also explore these front-end developer skills to see where the concepts overlap.
Architecture and Async Skills for Android Development
As you work with Android architecture, you’ll need to understand what each part is doing and how the pieces work together. If you use MVVM, for example, you should know what belongs in the ViewModel, what belongs in a repository, and how data moves between them. The same applies to Hilt and coroutines: know what problem dependency injection solves, how coroutine scopes relate to the Android lifecycle, and what can go wrong when asynchronous work outlives the screen that started it. These are the details you’ll need when working through an Android codebase and explaining your technical decisions in an interview.
MVVM, MVI, and the Repository Pattern
In MVVM, ViewModel stores the UI state that lives through configuration changes. Meanwhile, the UI listens to changes in the state and visualizes them. The repository mediates between the ViewModel and data source layers, which allows other parts of the application to ignore whether Room, network, or both data sources were used.
MVI takes a stricter approach: a single state model and explicit user intents make state changes easier to follow, particularly in larger screens and teams. MVVM can be simpler when the state doesn’t need that level of structure. But yes, neither is automatically better.
| Pattern | What it solves | When it’s overkill |
| MVVM | Separates UI state from application logic. | Very small screens with almost no state. |
| MVI | Makes state changes and user actions explicit. | Simple apps where a single state model adds unnecessary ceremony. |
| Repository | Keeps data sources behind one interface. | Tiny projects with one simple data source. |
Modularization follows the same principle. Several modules can be used to speed up the compilation time and establish ownership boundaries in a big application. Using six modules for a two-screen app to show its architecture is typically a good indication that the design is driving the implementation and not vice versa.
Dependency Injection with Hilt
Dependency injection removes the need for classes to construct all their own dependencies. That makes testing easier and gives you control over how long objects live. Hilt provides Android-specific integration on top of Dagger, while Koin is another option you’ll encounter.
Be aware of the difference between different scope annotations like @Singleton and @ViewModelScoped. The fact that DI can be described as “passing objects through constructors” is ignoring an important aspect interviewers typically look for – the creation, lifetime, and sharing of the dependency.
Coroutines, Flow, and Structured Concurrency
When you launch a coroutine from an Android application, the scope you choose determines how long that work can continue. viewModelScope cancels its work when the ViewModel is cleared, while lifecycleScope ties it to the lifecycle of its owner. GlobalScope has no such lifecycle boundary, so work started there can continue even after the screen that launched it is gone. That makes GlobalScope a poor choice for most application work.
You’ll also need to understand where your coroutine runs. Blocking work on the main thread can still freeze the UI, so withContext lets you move that work to an appropriate dispatcher. Cancellation is another part of this: a coroutine only responds to cancellation at suspension or other cancellation-aware points, so knowing how cooperative cancellation works matters when you’re handling longer-running tasks.
For data that changes over time, learn the difference between Flow, StateFlow, and SharedFlow, including how cold and hot streams behave. You’ll still encounter LiveData in older Android applications, so it’s useful to understand how its observable state compares with the StateFlow approach you’ll use in newer code.
If you’re also preparing for broader architecture and system-design discussions, system design fundamentals covers the concepts behind many of these application-level decisions.
Data and Platform Skills: Offline-First, Lifecycle, and Background Work
An app can work perfectly on an emulator and still break in production. Poor connectivity, interrupted requests, process termination, database changes, and Android’s background execution constraints can reveal issues that aren’t evident during regular development.
Local Storage, Networking, and the Offline-First Mindset
Think about what happens to your app’s data when the network is unavailable, the user closes the app, or the application gets updated. With Room, you should understand how entities and DAOs fit together, but also how migrations work and why a poorly handled schema change can cause problems after an app update. For DataStore, know what it gives you over SharedPreferences and when you would choose it. On the networking side, Retrofit and OkHttp bring in concerns such as interceptors, authentication token refresh, timeouts, and turning network errors into useful application states. For large lists, Paging 3 helps you load data in smaller portions instead of fetching everything at once.
And especially in India, you should prioritize understanding offline–first design. Unreliable connectivity, metered data, and changes between online and offline states are normal product constraints. A solid design keeps a local source of truth, supports optimistic updates where appropriate, queues changes for synchronisation, and has a defined strategy for conflicts.
Lifecycle, Configuration Changes, and Process Death
A configuration change and process death affect your app differently, so you need to know what state survives each one. When the device rotates, Android normally recreates the Activity while the ViewModel remains available. If the system kills the app process, the ViewModel is gone as well. Any state that needs to survive process death should therefore be stored through mechanisms such as SavedStateHandle or persistent storage.
Your Android platform knowledge should also include the current runtime permission flow, scoped storage, and the system Photo Picker. A useful way to test your understanding is to enable Don’t keep activities in Developer Options and run through the app again. You’ll quickly see which parts of your state are restored correctly and which ones depend on the Activity staying alive.
Background Work
Use the API that matches the job:
| Requirement | Right API | Common wrong choice |
| Deferrable work that should eventually run | WorkManager | A raw background thread |
| User-visible ongoing work | Foreground service | WorkManager for everything |
| Exact alarm behaviour | AlarmManager | Assuming WorkManager provides exact timing |
| Push notification or server event | FCM | Polling continuously in the background |
In addition, you must know about Doze, App Standby, Battery Restrictions, Notification Channels, Runtime Notification Permission, and Android’s background execution limitations. Knowledge of the API is only one part of the answer, the other being why you selected the API.

What Android Interviews in India Actually Test
The interview process varies by company, but Android roles at Indian product companies and larger app studios often include several of these stages: a DSA or problem-solving screen, an Android fundamentals round, an architecture or design discussion, an app system-design or machine-coding round, and a hiring-manager discussion.
Keep these areas in mind while preparing for Android interviews. You should be ready to explain how you would handle each situation and the technical choices you would make along the way.
- Lifecycle edge cases: A strong answer distinguishes rotation, backgrounding, and process death, and explains what survives each. A weak answer treats onCreate() and onSaveInstanceState() as a complete solution.
- Configuration changes: You should know what belongs in a ViewModel, what belongs in saved state, and why onSaveInstanceState is not a replacement for a ViewModel. If you can’t explain that distinction, architecture questions usually expose it quickly.
- Memory leaks: Know common causes such as an Activity Context held by a singleton, static references, non-static inner classes, or listeners that were never removed. You should also know how you’d investigate one using LeakCanary or a heap dump in Android Studio Profiler.
- Coroutine scoping: Be able to explain viewModelScope, lifecycleScope, cancellation, and why GlobalScope is usually the wrong choice for application work. Saying “coroutines run in the background” is not enough.
- App system design: You may be asked to design an image-loading library, an offline-first feed, a chat screen with message retry, or an analytics batching system. The discussion is about client-side architecture, caching, threading, retries, and observability, not drawing a collection of microservices.
The App System-Design Round
Many Android candidates find this part of the interview confusing, so it’s worth giving your preparation more attention here.
Suppose you’re asked to design an offline-first feed with pagination. Start by deciding where the UI gets its data. A sensible design is to make Room the single source of truth, have network responses update the database, and let the UI observe the database through Flow. New pages can be fetched as the user scrolls, while pending writes can be queued for later synchronisation. You then need to decide what happens when the same record changes locally and on the server, and how failed requests are retried. Finally, explain where you’d add logging and metrics so you can tell whether sync is failing in production.
That is the level of reasoning the interviewer is looking for because you won’t get extra points for adding microservices to a problem that runs mostly on the device.
The DSA Screen You Still Have to Pass
Even when you’re applying for an Android role, you may have to clear a general problem-solving round before you get to the Android-specific interview. DSA isn’t part of Android development itself, but you still need to prepare for it if the companies you’re targeting use DSA as an early screening round.
A structured DSA roadmap can help you work through the important topics in order instead of trying to learn every algorithm at once.
Scaler Alumni and Their Success Stories
How to Evidence Android Skills: Portfolio, Repo, and Resume
A certificate can show that you completed a course, but you still need to build evidence in order to show that you applied your mobile app developer skills to ship an app, fix a crash, handle a failed network request, or maintain a codebase.
If you can, include a published Play Store app with real users in your portfolio. You can also showcase a well-engineered repository with tests and CI. A tutorial project may be fine, but it should not be the only project you show.
A credible Android portfolio repository should make the engineering easy to inspect. Include a README that explains the architecture and the decisions behind it, tests that actually run, CI, screenshots, and a short note on what you’d change if you built it again. Don’t add modules just to make the architecture look impressive; explain why each boundary exists.
Three project types cover most of the checklist:
- Offline-first app: Room + Retrofit with caching, synchronization, and conflict handling.
- Compose application: A non-trivial state model such as a multi-step form or media player.
- Published app: A small app on Google Play with crash reporting and basic production monitoring.
Your Resume Should Show the Engineering
When you’re putting your android developer skills on a resume, show what you have changed and what improved because of it. Listing Kotlin, MVVM, Compose, or other technologies tells the reader what you used; a specific change with a measurable result tells them what you did with those skills.
Compare: Worked on an Android app using Kotlin and MVVM.
With: Migrated 14 screens from XML to Compose; reduced cold-start time from 2.1s to 1.3s and improved crash-free sessions from 97.4% to 99.2%.
When interviewers see such specificity, they get more room to ask questions and for you to answer about the topics you have already worked on. So when you put those numbers, they should come from measurements you took before and after the change. If you want to claim an improvement, you must establish the baseline first.
You can apply the same approach to testing: as you add tests to your projects, use automation and testing fundamentals to strengthen that part of your skill set.
Emerging Skills: Shipping to Play, Multiplatform, and AI-Assisted Development
Play Store and release engineering: the skill nobody lists
Interviewers ask “Were you able to ship it?” because releasing an app exposes problems that local development doesn’t. A production release means dealing with signing, Play Console requirements, staged rollouts, crashes, ANRs, app size, startup time, and builds that need to be reproducible.
For Google Play, you’ll work with Android App Bundles (AAB) and Play App Signing as part of the release process, rather than treating a successful debug build as a finished release.
Know the release-track flow from internal testing through closed and open testing to production, and understand staged rollouts well enough to stop one when Android Vitals show a problem. Target API requirements can turn platform upgrades into release work: from August 31, 2026, new apps and updates submitted to Google Play must target Android 16 (API 36) or higher, while existing apps need to target Android 15 (API 35) or higher to remain available to new users on newer Android versions.
First-time publishers also need to deal with Play Console policy requirements, including permissions declarations, the Data safety form, and privacy-policy requirements. R8 handles shrinking and obfuscation for release builds; keep the mapping files so crash reports can still be decoded. Baseline Profiles and startup measurements give you a way to improve launch performance, while CI/CD can automate builds, tests, and Play uploads. Play Integrity is another part of the release and app-integrity stack that you should know.
App size is to be considered when your users have slower or metered connections. A few extra megabytes aren’t just a build-system detail when the person installing the app is paying for the data.
Android developer verification is also becoming part of the release process. Google says the requirements begin taking effect on September 30, 2026, initially covering apps from participating stores in Brazil, Indonesia, Singapore, and Thailand; developers should check their Play Console status as the rollout expands.
Android Vitals also gives developers concrete quality thresholds to watch: Google currently defines bad behaviour as at least 0.47% of daily active users experiencing a user-perceived ANR or at least 1.09% experiencing a user-perceived crash across all device models.
Kotlin Multiplatform and Compose Multiplatform
Kotlin Multiplatform lets teams share code between Android and iOS while retaining access to native platform APIs. You can start by sharing the domain and data layers, where the same business logic and data handling can serve both platforms, while keeping platform-specific UI and APIs in their respective applications.
That is a different approach from Flutter or React Native, where the cross-platform UI layer is central. For that comparison, see Flutter vs React Native.
On-device ML and AI-assisted Android development
On-device ML is becoming an in-demand Android skill in products that need AI features to run directly on the device. ML Kit handles common vision and text tasks, while Gemini Nano supports selected on-device capabilities such as summarisation, proofreading, and image description. When you add one of these capabilities to an app, you’ll need to check whether the device supports it, how much latency it adds, and what your app should do when the capability isn’t available. For some use cases, that may mean falling back to a server-side model. You should also consider which processing can stay on the device, since keeping sensitive data there can reduce the amount of user information sent to a server.
AI tools can help you write Android code faster, but you still need to understand the code they generate. You should be able to review the output, spot incorrect or unnecessary code, and explain why it works before adding it to your application. Gemini in Android Studio and agent-based workflows can take care of boilerplate, implementation drafts, and some debugging work, so you can spend more time evaluating lifecycle correctness, architecture, testing, performance, and release safety. When AI generates part of your implementation, make sure you can still explain the code, test it properly, and recognise when the suggested approach doesn’t fit your application.
Android Developer Salary and Career Progression in India
If you’re comparing android developer salary in India, the range can vary substantially with experience, city, and the type of company you join. As a broad reference, Android developers with 0-1 years of experience may see around ₹3-7 LPA, while the 1-3 year range is roughly ₹4-8 LPA. For 4-6 years, salaries can fall around ₹5-11.3 LPA, and developers with 8+ years of experience may see ₹12 LPA and above. These figures are taken from Glassdoor as of now, but they may vary in accordance with the company and location.
Career progression usually moves from Android Engineer to Senior Android Engineer and then to Lead or Staff roles. After around five years, you may choose to go deeper into mobile architecture, platform engineering, or developer tooling, or move toward engineering management. As you move up, you’re expected to take ownership of larger and more ambiguous problems, not simply write more code.
Android specialists are also sometimes hired under a general SDE ladder and evaluated against the same engineering-level expectations as other software developers. You can see how those levels differ in SDE-1 vs SDE-2 vs SDE-3 level differences.
If you’re comparing Android with other software engineering roles, software developer salaries across roles can give you a broader view.

A Realistic 90-Day Plan to Close Your Biggest Gaps
The best way to hone your Android skills is to start with one focused project and use it to practise the areas you need to improve. Start with Kotlin and asynchronous programming, then add architecture and data handling, and use the final month for release and production work. Kotlin Multiplatform can come later once your Android fundamentals are solid.
Month 1: Build a small Compose application and use it to strengthen your Kotlin, state management, and coroutine skills. Keep the application simple enough to finish, but make sure you’re making the decisions yourself rather than following a tutorial step by step.
Month 2: Add Room and Retrofit and turn the application into an offline-first app. Store the data locally, fetch updates from the network, and decide what the user should see when the connection is unavailable. Add tests around the important paths so you can check that the application behaves correctly as you add more features.
Month 3: Publish the application and add crash and performance monitoring. Test the release on a real device, check what happens when the network is unavailable or the app is recreated, and use the release process to find issues that were easy to miss during local development.
You don't need to keep starting new applications to cover every Android concept. Finish one, publish it, and then use what you learned to improve the next project. By the end of these 90 days, you should have an application you can show in your portfolio and enough experience with its architecture, data flow, testing, and release process to discuss those decisions in an interview.
The Android-specific skills covered in this article can be learned through official documentation and codelabs. Give separate preparation time to DSA and system design as well, particularly if the companies you're targeting use them in their interview process. Those rounds require a different kind of preparation, so include them in your plan instead of leaving them until after your Android work is complete.
Conclusion
You might now have a clearer picture of what you’ll be expected to handle in an Android role: Kotlin and Compose, existing XML codebases, application architecture, coroutines and Flow, local and remote data, lifecycle behaviour, background work, testing, and the practical decisions that come with shipping an application.
Now look at the roles you want and compare their requirements with what you can do today. Pick the areas where you need more practice and use your projects to put them into practice. When you can explain why you chose a particular architecture, how your data moves through the app, what happens when something fails, and how you tested and shipped it, you have much more to discuss when the interview starts.

FAQ
1. What skills are required for an Android developer?
You’ll need Kotlin and Jetpack Compose, along with enough XML knowledge to work with existing codebases. You should also know an architecture such as MVVM, including how ViewModel and Repository layers fit together, and be comfortable with Coroutines and Flow. Room, DataStore, and Retrofit cover local storage and networking, while Android lifecycle, permissions, WorkManager, testing, and Play Store deployment round out the skills you’ll use in an Android role.
2. Is Kotlin necessary, or is Java still enough for Android?
Kotlin is now the expected language for new Android development. Java is still used for maintaining older codebases, but being limited to Java can rule you out of many product-company roles.
3. Do I need Jetpack Compose if my company still uses XML?
Yes. You may need to build newer parts of the app with Compose while maintaining existing XML layouts, RecyclerView code, and the interop between the two. Knowing both helps you work on newer development without getting stuck when you need to understand or update an older part of the application.
4. How long does it take to become a job-ready Android developer?
You can build the skills needed for an Android developer role in around six to nine months if you already have a programming foundation and can put in consistent work. In this time, you should learn Kotlin, Jetpack Compose, architecture, Coroutines and Flow, data handling, testing, and the Android lifecycle, while also building and shipping applications that let you practise these skills. You can then use the later part of this period to prepare for DSA, system design, and the other rounds you may face during the hiring process.
5. What is the salary of an Android developer in India?
According to Glassdoor, Android developer salaries in India typically range from around ₹4-10 LPA, although the actual figure can vary based on your experience, location, and the company you join. For the latest figures, you can check Glassdoor's Android developer salary data.
6. Is Android development still a good career in 2026?
Yes. Android remains a major mobile platform in India, and native Android skills continue to be used by product companies and app studios. The role increasingly includes architecture, performance, testing, and release engineering alongside UI development.
7. What do Android interviews actually test?
You can expect questions on lifecycle and configuration changes, memory leaks, coroutine scoping, architecture, and app-level system design. Many companies also start with a general problem-solving or DSA round before the Android-specific rounds.
8. Which projects best prove Android skills?
Choose projects that let you demonstrate the Android skills you’re likely to discuss in an interview. An offline-first app can show how you use Room, Retrofit, and a defined sync strategy, while a Compose app with non-trivial state can demonstrate your understanding of state management and UI architecture. A published Play Store app can also give you experience with testing, release, and production issues. These projects give you specific technical decisions and problems to discuss during the interview, while tutorial projects can help you learn the basics and reinforce individual concepts.
