Android SDK Jobs

Saya ingin sebuah aplikasi pendidikan khusus untuk perangkat Android. Aplikasi ini harus menghadirkan materi belajar interaktif—misalnya video singkat, kuis pilihan ganda, dan ringkasan teks—agar pengguna dapat memahami topik-topik dasar secara mudah. Ruang lingkup pekerjaan: • Rancang antarmuka Material Design yang sederhana dan responsif. • Bangun fitur utama: daftar modul belajar, pemutar konten (teks + video), kuis dengan penilaian otomatis, serta halaman rekap kemajuan. • Pastikan aplikasi dapat berjalan mulus di Android versi terbaru dan tetap kompatibel hingga Android 8.0. • Sertakan kode sumber lengkap (Kotlin atau Java), panduan build, dan file APK siap rilis ke Google Play. Kriteria penerimaan: aplikasi stabil tanpa crash, navigasi in...

I need a developer who can wire proper play / pause as well as previous-next buttons into my existing Android app so that they appear on the lock screen and in the pull-down notification shade (just under the Wi-Fi and other system icons). The media involved is music only—no video or podcast handling is necessary—so you can focus on a clean MediaSession implementation. The notification tab should let users control music playback directly; no extra settings tiles or album art tweaks are required, the default visual style is fine. My current build is already functional inside the app, I just haven’t been able to surface those controls outside it. All work must remain compatible from Android 8.0 upward. Please deliver: • Updated Kotlin/Java code (or clear patches) tha...

I need an Android-only solution that quietly installs on a phone and listens over the local network (Wi-Fi) for two simple parameters coming from my desktop or server: the destination number and the SMS text. Once received, the service should fire off the message through the device’s native SMS manager—no on-screen interface or notifications, just a background service that starts with the device and keeps running. Because it will run headless, please take care of permissions (SEND_SMS, RECEIVE_BOOT_COMPLETED, FOREGROUND_SERVICE where required) and any battery-optimization whitelisting so messages are never blocked. I’m fine with classic Android Java; no Kotlin is needed unless you feel it speeds development. Communication can be your choice of lightweight REST endpoint...

I need a new Android mobile app built from the ground up. The core idea is clear, but I am looking for guidance on structuring the features, choosing the right tech stack, and bringing the entire concept to life on the Google Play ecosystem. Here’s what I expect: • A polished, fully functional APK ready for submission to the Play Store. • Clean, well-documented code so future updates are straightforward. • A simple, modern UI that follows current Android design guidelines. • Basic onboarding and an in-app help screen to ensure users instantly see value. I’m flexible on development tools—Kotlin or Java is fine as long as the result performs smoothly across the latest Android versions. Let me know which libraries or frameworks you recommend for...

I need an experienced Android developer who can turn a fresh concept into a polished application whose primary purpose is to earn money from day one. The platform is strictly Android, so everything—from the architecture you choose to the UI patterns—should follow current Android best practices and Google Play guidelines. My main focus is direct revenue generation. I’m open to any combination of in-app purchases, subscriptions, rewarded ads, or other monetisation models you feel confident implementing. What matters most is a clean, maintainable code-base, fast load times, and a friction-free user experience that keeps people engaged and spending. Deliverables I expect • Full source code (Kotlin or Java) with clear documentation • Signed, release-ready APK/A...

I have developed an android game and I am looking for including ad mobs (banner, interstitial and rewarded). However, ads are not coming including test ads. I need someone to help fix it. Technical expertise required - native android, cordova, javascript, html, XML, ad mob, github

I maintain the “MediFind – Chemist App” on Google Play and have just received the policy notice that it must target the latest Android version ahead of the 31 Aug 2026 deadline. Right now the project still declares targetSdkVersion “API 36 or Higher”, yet Play Console is flagging the bundle because the compiled artefact is older. ****And Needs to add sound in one Place. Your task is to bring the entire codebase up to the current target API level accepted by Google Play, upgrade Gradle tooling, and resolve any breaking changes in code or third-party dependencies. The code is a standard Android Studio project (Java & a bit of Kotlin), published as an AAB; minSdkVersion must stay exactly as it is so existing users are not cut off. Key outcomes I need fro...

I need a senior-level programmer to build a bootable Android virtual phone image that mirrors the experience of a physical device while running entirely inside a host system (similar in spirit to VMOS). Core requirements • The virtual environment must present itself as a standard Android handset. • Google Play Store has to work out of the box, and I must be able to install any additional APKs of my choice. Internet browsing is not critical; the focus is on app execution. • Instead of a live camera feed the system should expose a video carousel: a predefined folder of clips that loop automatically, appearing to any app as if they were coming from the camera. • The host environment must stay hidden so installed apps treat the image as genuine hardware—no...

I'm looking to develop a simple yet efficient Android application for printing lab certificates on card size using my printer. The application should be user-friendly and encompass essential features for seamless operation. Key Features: - Certificate Template Selection: The app should provide various templates for different types of certificates. - Database of Certificate Entries: A built-in database to keep track of all certificate entries, making it easy to print duplicates or track issued certificates. -Printing Preview: A feature that allows users to preview the print before actually printing, ensuring accuracy and saving resources. User Interaction: The application should be designed for manual data entry within the app. Users should be able to input data for the certificates ...

I have a RecyclerView driven by a LinearLayoutManager. Card taps are currently picked up through an OnPress handler, and I already keep the underlying data in a ViewModel. The problem is simple: when a user opens a detail screen from any card and then presses the back button, the list always jumps back to the very top instead of revealing the card they originally tapped. I need the list to remember its exact scroll position so that returning feels seamless. You’re free to solve it however you feel is cleanest—saving and restoring the layout manager state, using the Navigation component’s back-stack handling, or any other proven method—as long as: • the previous scroll position is restored every time, • orientation changes don’t break the fi...

I need a skilled Android developer to transform my concept into a fully functional, Play-Store-ready application. The project targets the latest Android releases, so solid knowledge of native Android (Kotlin or Java) is essential. I’m open to modern frameworks such as Flutter if you can guarantee a smooth Android-only build. Scope • Translate my wireframes and user-flow notes into an intuitive UI that runs smoothly across common screen sizes. • Build the complete feature set we finalise together; possibilities may include push notifications, secure user sign-in, or even in-app purchases, so prior experience with Firebase, Google Play Billing, or similar services is valuable. • Integrate any necessary back-end APIs, set up local data caching, and ensure the app remains...

I need an experienced Android reverse-engineer to take an existing mobile app, remove its subscription checks, unlock every premium feature, and disable ads in a way that leaves the rest of the functionality untouched. This is a fully obfuscated APK that performs online licence verification, integrity tests, and signature validation, so you will have to bypass anti-tamper code, rebuild, align and re-sign the package so it installs cleanly on Android 8 through 14. I will provide the latest APK and, if helpful, a video walkthrough of the areas I want freed. You can use any combination of JADX, Apktool, Smali/Baksmali, Frida, or your own in-house tooling—as long as the final build is stable and the method is reproducible. Deliverables • Patched, installable APK with subscriptio...
