I need my existing Android mobile application refreshed so it runs smoothly on today’s phone models. This is strictly an update project—no full rebuild—so you’ll be working with the current codebase. What I expect: • Analyse the present Android project, migrate it to the latest stable SDK, and resolve any deprecated APIs that affect phone performance. • Update layouts and resources so screens scale properly across modern resolutions and aspect ratios. • Eliminate crashes or warnings flagged by Android Studio and the Play Console, delivering a clean release-ready AAB/APK. • Push all changes to my Git repository with clear commit messages. Acceptance criteria 1. The new build installs and functions without crashes on Android 8.0 through the latest release. 2. Google Play pre-launch report shows no critical or high-severity issues. 3. Source compiles with zero lint errors. I will provide the existing source, assets, and a quick walkthrough video once we lock timelines. Feel free to recommend additional tweaks after you review the project.

I’d treat this as a careful modernization job, not a rewrite. The goal is to preserve what already works, remove what modern Android no longer tolerates, and leave you with a clean build that survives both real devices and Play Console checks. I’m a senior Android engineer with 9+ years of experience working with legacy codebases, SDK migrations, deprecated APIs, performance issues, Gradle/build problems, lint, Play Console warnings, and production releases. I’m also currently working on an OS built on top of AOSP 16, so Android compatibility and platform-level changes are very familiar territory for me. I’ll first audit the current target/compile SDK, dependencies, manifest, deprecated APIs, layouts, and crash/lint output. Then I’ll update only what is necessary, verify Android 8+ compatibility, test modern screen sizes/aspect ratios, and address Play pre-launch issues before producing the final AAB/APK. Every change will go through your Git repo with clear commits, so you can see exactly what was modified and why. If you share the project and walkthrough, I can review the current condition first and give you a precise upgrade plan before touching the stable parts.

✋ Hi, the main risk in an update-only Android project is changing SDK/dependencies too aggressively and introducing regressions into code that already works. I’d first audit the current Gradle setup, target/compile SDK, dependencies, deprecated APIs, crash logs, Play Console warnings, and device-specific layout issues. Then I’d upgrade incrementally, fix compatibility problems, modernize only the affected APIs/resources, and regression-test key flows across Android 8 through current versions. I’d finish with lint cleanup, release AAB/APK generation, and clear Git commits so every change is traceable. Is the current app written mainly in Java, Kotlin, or a mix of both?

Hi, I'm Denis, a full-stack developer specializing in Android app modernization and SDK migrations. I understand your needs: you have a working app that needs to run reliably on current Android devices. This means updating the SDK, fixing deprecated APIs, resolving layout scaling issues, and eliminating crashes or lint warnings before Play Store release—all without a complete rewrite. I've handled similar projects, balancing necessary updates while preserving existing logic. My approach is straightforward: audit the code for deprecated APIs and compatibility issues, update build configuration and dependencies, refactor layouts for modern screen densities, run systematic lint analysis, and test across target Android versions. The workflow starts with a thorough code review identifying deprecation warnings and crash sources. Then I'll update the SDK and gradle configuration, migrate deprecated APIs to modern equivalents, adjust layouts for proper scaling, resolve lint errors, and ensure the build passes Google Play's pre-launch checks. All changes are pushed to your repository with clear commit messages for full transparency. Older code sometimes relies on now-discouraged patterns. I'll handle these thoughtfully, keeping functionality intact while following current best practices. For large codebases, we can prioritize critical issues first and refine based on testing feedback. I'm ready to start immediately. Let's discuss the details. Thanks, Denis.

Hello, I have reviewed your requirements and can update and refine your existing Android application without rebuilding it from scratch. I have 10+ years of experience with Android development, SDK migrations, deprecated API updates, UI responsiveness, crash fixing, Play Console issues and release builds. I can work directly with your current codebase, migrate it to the latest stable SDK, resolve warnings and compatibility issues, and prepare a clean release-ready AAB/APK. WORKING FLOW: Project Review → Analyze the existing Android codebase, dependencies, SDK configuration and current issues. SDK & API Update → Migrate to the latest stable SDK and replace deprecated APIs where required. UI Refinement → Update layouts and resources to support modern screen sizes, resolutions and aspect ratios. Crash & Lint Fixes → Resolve Android Studio warnings, crashes and Play Console issues while maintaining the existing functionality. Testing → Test the application across Android 8.0 through the latest supported release and validate the release build. Git & Deployment → Push clean, well-documented commits to your repository and provide the final AAB/APK ready for Play Console submission.

Hi, Your focus on maintaining and modernizing the existing Android app to run smoothly across current devices aligns with the critical challenge of ensuring compatibility and stability without a full rebuild. The main technical risk is ensuring the migrated SDK and updated layouts handle the wide range of Android OS versions and device resolutions without regressions or crashes. While my recent projects have centered on backend AI systems and complex data pipelines, I have extensive experience designing scalable, maintainable architectures and managing legacy codebases with incremental improvements. This approach is essential when updating mobile apps to avoid introducing instability. I typically design updates by separating migration tasks, UI scaling adjustments, and thorough static and dynamic analysis to catch deprecated APIs and runtime issues early. This modular approach allows focused validation and rollback if needed. What will determine reliability here is comprehensive linting, crash analytics, and pre-launch testing automation to ensure the app meets your acceptance criteria consistently. I can start by reviewing your current repository and build setup to outline the SDK migration plan and identify critical deprecated API usages. Thanks, Clifton

Hello, I can update and stabilize your existing Android application without rebuilding it from scratch. I’ll first audit the current Java/Android Studio project, Gradle configuration, SDK targets, dependencies, deprecated APIs, and existing crash/lint issues. Then I’ll migrate it to the appropriate stable SDK, update affected APIs and layouts, fix compatibility problems across Android 8.0 through the latest release, and test the main screens on different resolutions and aspect ratios. I’ll also review Play Console/pre-launch issues, produce a clean release-ready AAB/APK, and push the changes to your Git repository with clear, organized commits. Looking forward to work with you. Thanks

Hello, your Android update is a focused modernization task, and I can work directly within the existing codebase rather than forcing a rebuild. I’ll review the project structure, migrate it to the latest stable SDK, replace deprecated APIs, refine layouts for current aspect ratios, and address Android Studio, lint, crash, and Play Console findings. I’ll validate compatibility from Android 8.0 through the latest release, prepare a clean release-ready AAB/APK, and push organized commits to your Git repository. One useful improvement would be adding a lightweight automated smoke-test checklist for critical flows, helping prevent regressions after future SDK updates. I’ll use your walkthrough and acceptance criteria to keep the refinement practical and measurable. Thank you! Muhammad
