Android SDK Jobs

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...

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...

I need a native Android application that presents users with a series of mathematical–calculation quizzes. The app’s core flow is simple: display a question, accept the user’s answer, immediately show whether it is correct, and track scores over time. Key functions • Dynamic question generation for arithmetic operations (addition, subtraction, multiplication, division) with adjustable difficulty. • Timer option so users can race against the clock or practise untimed. • Scoreboard that stores results locally and can be reset from Settings. • Clean material-design interface that scales well from small phones to tablets. • Written in Kotlin (preferred) or Java, and built for the current stable Android SDK. Deliverables • Fully ...

I’m looking for a developer who can turn my idea into a fully functioning Android e-commerce app. The goal is to let users browse products, add them to a cart, and complete checkout smoothly on their phones. Key objectives • Build a clean, intuitive Android interface that loads quickly on mid-range devices. • Implement core e-commerce features: product listing, search and filtering, cart management, secure checkout, and basic order tracking. • Connect the app to a simple, well-documented backend (Firebase, Supabase, or another lightweight stack you’re comfortable with). • Integrate at least one popular payment gateway suitable for my target market. • Provide authentication via email or social accounts and store user data securely. Deliverables...

I need a skilled Android developer to build a dedicated e-commerce application from the ground up. The core goal is to give users a smooth shopping experience on Android phones and tablets, so performance and intuitive UI patterns matter as much as clean code. Here are the essentials I must see in the first release: • Product catalog that lets shoppers browse, filter, and view detailed item pages • Shopping cart that updates in real time and persists between sessions • Secure payment-gateway integration (I’m open to Stripe, PayPal, or any PCI-compliant option you recommend) Everything should be written natively for Android—Kotlin is my preferred language, though Java is acceptable if it speeds up delivery. I will provide branding assets and product data ...

I need a straightforward Android application that lets diners open our restaurant’s menu instantly after scanning a table-side QR code. At this stage the app is purely for menu browsing—no ordering cart, no payment gateway—so the build can stay lean and focused on fast loading, clear category navigation, and an easy way for staff to keep dish names, photos, prices, and descriptions up to date. Here is what I’m expecting: • A clean Android APK (plus full source) that launches directly into a QR scanner and then displays the corresponding menu screen. • Menu data can live in any lightweight back-end you are comfortable with (Firebase, simple REST JSON or similar is fine) as long as content updates show in the app without having to publish a new build. ...
