Android SDK Jobs

I need a simple Android app for a paid market analysis service. The admin writes and publishes articles daily on Indian markets (Nifty 50, Sensex) and crypto. Users pay a monthly subscription to read them. It is essentially a paid news app. Budget: ₹30,000 fixed Timeline: 4 to 5 weeks Platform: Android only (Flutter) Features (only these, nothing extra) Login with mobile number OTP Home screen with latest articles Tabs: Home, Crypto, Sensex, Nifty 50. These are only article categories, no live data for Nifty/Sensex. Live crypto price only (BTC, ETH and a few top coins) on the Crypto tab, using Binance/CoinGecko free API directly in the app, no server needed Article list and article page with Hindi and English support Plans: Basic ₹499/month and Pro ₹999/month, with a 7-day trial UPI paymen...

Project: Android APK Trojan Detection – Security Analysis and Resolution My released APK triggers “Trojan” alerts on some Xiaomi, OPPO, and vivo devices. I need an experienced Android security engineer to identify the root cause and help resolve the issue. The initial investigation should focus on potential security detection triggers, including suspicious code signatures, permissions, third-party libraries, and APK components. To the best of my knowledge, no third-party SDKs are included. However, the app requests both standard and sensitive permissions, which should also be examined. Scope of Work Phase 1 – Initial Security Analysis ($100–200) - Decompile and analyze the APK to identify potential detection triggers. - Investigate suspicious code, permissions...

I’m adding a UART-based audio path to the Android build of my product and now need the equalizer layer. The goal is strictly audio processing: the app (or library) must intercept the UART audio stream, apply EQ and other effects in real time, then pass the processed signal back to the system. Core requirements • Equalization controls – band-based sliders plus overall gain. • Optional audio effects such as bass-boost or reverb that can be toggled on/off. • A dual-preset system: ship with a set of predefined curves (Rock, Pop, Classical, etc.) while also giving users full freedom to create and save their own custom EQ profiles. Please keep the code clean, documented, and compatible with recent Android SDK levels. I will test with both physical hardware over...

I’m days away from releasing a brand-new Android app and need a person with at least 12 Gmail accounts to help test it either on your phone or laptop. Once we start, I’ll share the APK through a Gmail-accessible link, a concise usage guide, and a feedback template. Here’s what I’m after: • Install the build on your everyday Android smartphone and, if you have one handy, a tablet as well so we can see how the UI scales across form factors. You can also open it on an emulator or desktop tool for extra checks, but that’s optional. • Explore every screen, trigger every button, and deliberately push each workflow until you’re certain it behaves—or misbehaves. • Capture notes on the three areas I care about most: User Interface quirks, C...

I need help verifying how my Android app behaves when it just sits in a user’s pocket. The focus is narrow: measure and document idle state battery drain. To do this properly you’ll sign in with several different Gmail accounts (the app offers account-based personalisation), leave the app installed on one or more physical Android phones, and capture how much power it quietly consumes over set time windows. Here’s what I’m expecting from you: • A clear test plan that shows the steps you’ll take to track idle consumption (e.g., using Android Battery Historian, adb shell dumpsys batterystats, or similar tools). • Screenshots, raw logs, and a concise written summary that spotlights any abnormal drain compared to baseline device usage. • Note...

I need a developer who can give me full control over Android 15’s User Interface directly from the device itself—no desktop tools or ADB sessions. The goal is a portable-friendly solution that lets me edit: • Icons and Themes • Navigation Bar • Home Screen Layout • …and any other visual elements we can reasonably expose Whether you achieve this through a standalone APK, an overlay engine, or a rootless AOSP mod is up to you, as long as it runs smoothly on stock Android 15 phones and tablets. Deliverables 1. Compiled, installable package (APK or module) 2. Source code with clear build instructions 3. Step-by-step user guide that shows how to apply each UI change and roll it back 4. Brief testing report confirming the app works across a...

I’m adding a small yet important interaction to my Android app: when a user performs a long-press on any video clip, that clip should become “pinned.” A pinned clip must stay on the device indefinitely, while every unpinned clip should be automatically removed exactly one hour after it was created or downloaded. What I already have • The app already plays and lists video clips; you’ll be working inside an existing Android project. • Current codebase is in Kotlin, but clean Java is acceptable if you keep the modules consistent. What I need from you • Detect a long-press gesture on each clip thumbnail or list item and toggle its pinned state visually (e.g., overlay icon or colour change). • Persist the pinned flag locally so it survives a...

I need an Android-only application that lets gamers join my Free Fire tournaments quickly and securely. The single must-have feature right now is a streamlined player-registration flow that relies on phone-number verification rather than email or social logins, so every user who downloads the app can sign up with an OTP and land straight inside the lobby. Once registered, participants should see their profile and a simple “Join Tournament” button (backend logic can be stubbed for now; I mainly want the registration piece working flawlessly). An intuitive material-design interface, clean Firebase or similar real-time database integration for storing user details, and well-commented source code are all part of the hand-off. Deliverables • Production-ready APK and full so...
