SDK Android Jobs

I urgently need a seasoned Android engineer to take a brand-new idea from concept through to a fully working application. The exact feature set is still open for discussion, but whatever we build must run smoothly on both the latest devices and older phones and tablets without breaking UI or functionality. You will handle architecture, coding, testing, and deployment to Google Play, providing me with the full source code and a signed APK at each milestone so I can track progress. Expect to optimise for performance, follow modern Material guidelines, and implement solid backward-compatibility strategies—whether that means leveraging AndroidX, shrinking the APK with ProGuard/R8, or tailoring layouts with resource qualifiers. Clear, well-commented Kotlin or Java, Git-based version...

I have two signed Android APKs that share the same brand: a Chinese-language build that already handles user registration smoothly, and an English-language build that currently lacks this flow. My goal is to extract every user-management API call from the Chinese APK—endpoints, headers, payload structures, encryption or signing logic—and transplant that functionality into the English APK so both variants register users in exactly the same way. What I can provide: • The release APKs for both language versions • Valid test accounts and server access for live registration checks • Any additional assets the Chinese build relies on (native libraries, certificates, config files) What I need from you: • Decompile, inspect and document the Chinese APK (jadx, a...

The app should allow users to: - Turn the device on/off - Adjust settings - Schedule operations - get present status - device voltage regulation Ideal skills and experience: - Strong Android development skills - Experience with IoT communication protocols, particularly over Wi-Fi - User-friendly UI/UX design - Background in setting up secure connections for device control

Hello, I need a custom mobile app that runs on Google Pixel 8 and newer. The app should open the Wire application, go through my entire contact list (500+ contacts), and send the same message to each person individually - no group chats should be created so that recipients remain anonymous to each other. Key features • Automatically navigate to each contact in Wire and send the message. • I select the text manually each time before sending starts. • Built-in log that records: – Message sent to each contact – Any error messages/problems – Exact time of each message sent • Runs entirely on the phone as a standalone Android app without requiring a computer or browser. • Ready to install via APK or Google Play (internal test channel is okay). Techn...

Jag behöver en skräddarsydd mobilapp som körs på Google Pixel 8 och nyare modeller. Appen ska öppna Wire-applikationen, gå igenom hela min kontaktlista (500+ kontakter) och skicka ett och samma meddelande till varje person individuellt – inga gruppchattar får skapas så att mottagarna hålls anonyma för varandra. Viktiga funktioner • Automatiskt navigera till varje kontakt i Wire och skicka meddelandet. • Jag väljer texten manuellt varje gång innan utskicket startar. • Inbyggd logg som registrerar: – Skickat meddelande till varje kontakt – Eventuella felmeddelanden/problem – Exakt tidpunkt för varje skickat meddelande • Körs helt på telefonen so...

My production Flutter app has begun to misbehave on Android 14, 15 and 16 preview builds. The root cause is obvious: the codebase is still on an older Flutter release and the underlying Android SDK has marched on. I need the entire project migrated to the latest stable Flutter version, compiled against the newest Android SDK, and thoroughly tested so it works smoothly on those three OS versions. The scope is simple but critical: upgrade the Flutter framework and all dependent packages, refactor any deprecated APIs, fix compile-time warnings, and resolve run-time crashes or layout glitches that appear only on the newer Android versions. Afterwards I expect a clean, reproducible build (Android App Bundle) plus a short changelog summarising what was updated and why. Deliverables • Up...

I’m building a dedicated Android application that lets users browse, purchase, and instantly access digital products. Think of items such as e-books, audio files, software keys, or any downloadable content that can be delivered straight to the user’s device the moment a transaction is confirmed. What I’m looking for is an Android developer who can take this concept from clean architecture through to launch on Google Play. The core of the job is creating a smooth catalogue and checkout experience optimised for mobile, then handling the secure delivery of the purchased files. Clean code, reliable state management, and attention to UX details (progress indicators, purchase confirmation, download status, error handling) are all important to me because the product is intangib...

I’m building an Android-only sports application that focuses on delivering fresh match highlights to fans and alerting them the moment a new clip is available. The core of the project is straightforward: smooth video playback, a clean Material-inspired interface, and reliable real-time notifications. Here is what the finished product must do: • Install on Android 10+ and present a scrollable feed of recent highlights pulled from my existing JSON/CDN source. • Stream each clip in HD without stutter and allow basic share functionality. • Trigger push notifications (Firebase Cloud Messaging or a comparable service) within seconds of a new highlight being published. • Follow best practices for maintainable, modular code so I can layer in live score updates or player ...

I am rolling out an in-dash Android interactive display and need a seasoned AOSP specialist to turn the stock source into a lean, security-hardened custom ROM. The target hardware is a car-grade unit that hosts a camera alongside proximity and accelerometer sensors, so the build must include the right HALs and permissions for those components. What I want you to handle: • Fork the AOSP branch that best matches our SoC, import or craft the correct device tree and board-config, and fine-tune the kernel where necessary. • Strip every Google Mobile Service while preserving base Android stability. • Apply low-level security tweaks (SELinux policy work, verified boot, hardening flags). • Set up seamless OTA delivery (delta or full images) so field upgrades stay painless. &bu...

My Tamil-language FM radio app is written in Java and built in Android Studio. A recent refactor has left me with a mix of syntax problems (mainly misplaced brackets and missing semicolons) and a couple of runtime crashes tied to fragment lifecycle calls. The issues are isolated to the UI layer: the now-playing fragment, its data-loading helper, and the activity that hosts them. I can point you straight to the offending methods, but I need a clean, compile-ready project and a brief note on what you changed so I can learn from the fix. You’ll be working with: • Android Studio (latest stable) • Java source only – no Kotlin in this module Acceptance: the project builds without warnings, launches, and the UI loads station data and switches fragments without thro...
