Android SDK Jobs

I need a mobile application built specifically for Android that serves as a social-networking platform. The core idea is to let users create profiles, follow or connect with others, and share posts in a scrolling feed. Key needs • Clean onboarding with email or phone verification • Personal profile pages with photo, bio, and basic stats • Real-time feed where users can post text, images, or short videos • Like, comment, and share interactions • Push notifications for new follows, mentions, and comments • Secure back-end API and database setup (Firebase, Supabase, or similar) • Light, modern UI that follows current Android guidelines I’m looking for someone who can handle the full cycle—from setting up the database and API t...

I have a promising ball-pool title in the works and now need someone who is ready to own the Android build from here through launch and beyond. The core gameplay is already framed out, but I want a developer who can refine the physics, tighten performance, squash lingering bugs, and help me push a polished, commercial-grade release to Google Play. Key features on the roadmap are multiplayer mode, fully customizable tables and cues, and a robust in-game currency system. All art and effects must feel authentic—think clean, realistic tables, balls, and lighting rather than a cartoon look. To set us apart from the crowd we will layer in special power-ups and a couple of fresh game modes that aren’t found in the usual eight-ball experience, so comfort designing and balancing new me...

I have an Android app that displays a scrolling list of short text clips. I now need a quick-pin workflow: • When the user single-taps a clip, it should toggle into a “pinned” state and remain visible indefinitely. • Any clip that is not pinned must be automatically removed exactly one hour after it is created (or last edited), even if the app is closed in the meantime. • Visual feedback is important: pinned items should be clearly distinguishable from regular ones (icon, color badge—your call, as long as it follows Material guidelines). You are free to work in Kotlin or Java and may choose the persistence layer that best fits—Room, DataStore, or another solution—so long as the auto-deletion runs reliably in the background (WorkManager or ...

I need an Android app that takes photo of invoice and automatically pulls out the key data I care about: • Invoice number • Total amount • Sender and receiver details • All article/line items A simple, clean UI is fine—one button to select or upload the invoice photo or click a photo and a results screen that displays the extracted fields. Storing the parsed data in some database will make it easy for me to feed the information into other systems later, so please include that. You are free to use any reliable parsing library as long as it runs smoothly on recent Android versions. The final deliverable should include: 1. The compiled APK for quick testing on my phone. 2. Full, well-commented source code that builds in Android Studio. Acceptance cri...

I have a Mediatek 8168-based tablet (board ID tb8168p1_bsp, retail model Score 7T). I can put the device into BROM mode with mtkclient and it identifies as “SBC enabled = true”. What I need now is a fully working Android build custom-tailored for this hardware and a reliable procedure to get it flashed onto the tablet. The goal is a clean, stable Android ROM—version is flexible, so feel free to recommend the best fit for MTK 8168 in terms of driver support and security updates. I do not yet have a suitable ROM image, so I’m looking for someone who can build or port one from source (AOSP or other open-source base) and walk me through flashing it. Key deliverables • Bootable Android system image (system, vendor, boot, dtbo, vbmeta, etc.) compatible with tb816...

IMPORTANT UPDATE – READ CAREFULLY This is NOT a design contest. This project was mistakenly posted as a contest. It is actually a highly technical Android development task. Only serious Android developers with experience in LSPosed, Zygisk, Magisk modules and Camera2 internals should participate. Generic diagrams, flowcharts, AI-generated explanations or conceptual images will NOT be considered valid submissions. Technical Objective Device: Pixel 8a (akita) ROM: EvolutionX 15 (Android 15) Root: Magisk + Zygisk + LSPosed Goal: Force a USB UVC external camera to behave as the ONLY usable system camera. Requirements: Any app requesting a camera must open ONLY the external USB UVC camera. Internal physical cameras must be unusable or invisible. No ROM building. No vendor mod...

My Android app is ready to go—code signed, fully tested, and sitting in its final AAB build. I already have a verified Google Play Console account; what I need now is a smooth, error-free deployment. Here’s the scope: • Create the production release in Play Console, upload the AAB, set up the release notes, and handle any bundle optimiser warnings. • Populate the store listing with the assets I provide (screenshots, icon, short and full descriptions, privacy policy URL). • Configure pricing, countries, content rating, Data safety form, and all policy declarations so the submission is 100 % compliant. • Walk me through the review and rollout steps so I understand how to push future updates myself. A successful hand-off means the app is live (or at l...

At the moment we need several users for our android app RingApp in HUNGARY with YETTEL SIM card to help test communications and fight fraud! Applicants will be required to receive test calls from other users - the call will be automatically declined. Users can keep the app working in the background - the tasks will be done automatically. Our RingApp application requires an android phone and SIM card: YETTEL We pay 5 USD for every set of 200 calls via Freelancer. Milestone is 5 USD. To start the contract you need to sign up with your YETTEL SIM mobile number and turn on "Auto-perform tasks" in the "profile" section.

I need an experienced Android developer to turn my concept for a Utility/Tools application into a polished, ready-to-publish APK. What I’m after • A clean, well-structured Android codebase written in Kotlin or Java. • An intuitive UI that follows current Material Design guidelines. • Core utility features implemented exactly to spec (I will share wireframes and user stories once we start). • Basic analytics, crash reporting, and in-app update handling. • Clear build instructions so I can compile the project locally. I’ll handle all artwork and copy; I just need you to integrate the assets and ensure everything runs smoothly on recent Android versions. Regular progress updates through Git or a similar repo are important to me, and I’d...
