I’m planning to release a new Android-based game and need a developer who can take it from concept to a polished APK on Google Play. The project is purely mobile—no web or iOS components—so your focus will be on Android Studio, Java / Kotlin or a preferred game engine such as Unity or Godot. Here’s what I have in mind: • Core gameplay loop, menus, and simple in-app sound effects • Clean, responsive UI that scales well across common screen sizes • Integration of basic ads or rewarded video (AdMob or similar) • Documentation plus full source code so future updates are straightforward Once the first playable build is ready, I’ll test it on a range of devices and send feedback; we’ll iterate until the final version is sta...

I have an Android application that is experiencing issues related to SSL pinning and AP...The app currently fails to connect properly to backend APIs due to SSL pinning validation errors. I need an experienced Android security developer to: • Analyze the current SSL pinning implementation • Identify why API calls are failing • Properly configure or fix SSL pinning • Ensure secure and stable API communication • Test the solution thoroughly Requirements • Strong experience with Android (Java/Kotlin) • Experience with SSL pinning (OkHttp, Retrofit, TrustManager, etc.) • Knowledge of Android network security config • Understanding of certificate chains and HTTPS validation • Ability to debug APK or source code Please include: • Rele...

...captured as reliably as the typed sections. The database is already provisioned; I will share connection details and a simple schema suggestion (doc_id, page_no, original_block, extracted_text, confidence_score). If you would rather propose a better structure, I’m open to it as long as each text block can be traced back to its page and position. Deliverables • A script or small application (Python, Java, or PHP are all fine) that ingests each PDF, performs OCR, and inserts results into MySQL. • SQL dump or migration file that recreates any additional tables you introduce. • Brief read-me explaining setup, dependencies, and how to rerun the process on future files. • Sample run on three provided PDFs demonstrating the expected accuracy and table...

...choice • Loan application and approval dashboard • Before loan disbursement, the app must harvest and store the user’s full contact list (names, phone numbers, email where available) after an explicit consent prompt that meets Google’s limited-scope contacts permission guidelines • In-app chat support so users can reach our team in real time Tech preferences Native Kotlin is ideal, but Java is acceptable if you already have strong, reusable modules. I will host the back-end; you just need clean REST endpoints, well-documented, and an admin panel (web or Firebase console) where my staff can view KYC status, loan requests, and the exported contacts data. Deliverables 1. Android Studio project, cleanly organised, with source code and buildable ...

...management, Java, database administration, and cloud services. Before diving in, could you clarify a few details to better tailor the guide Project Deliverables Server Deployment: Hybrid database approach Distributed Cluster Deploy the latest Signal Server (Java) and WebRTC signaling (Spring Boot/Node.js/Socket.io) Configure server dependencies (Java, PostgreSQL/Redis, Maven) • Infrastructure: Are you planning to deploy on a our server • Version: need the latest official Signal Server (Java-based) • Customization : rebrand the app or simply run a private instance Configuration & Customization: Set up config .yml for production Optional branding or private instance configuration ________________________________________ Core System Requi...

You’re free to choose the language and framework you’re most productive with (Python + PyInstaller, Electron, C#, Java—whichever suits the task best) so long as the final executable is hassle-free for the end user. I’ll happily share the full feature outline once we start, but the focus will stay on clarity, performance, and ease of use. If you have a portfolio piece that shows a similar utility, feel free to point me...

The goal is to build a lightweight Android utility focused on task management. Core capability centres on notifications and reminders—covering everyday to-dos as well as specialised payment nudges and simple order-processing follow-ups—delivered reliably on Android 8.0+ devices. Scope of work • Create the full Android application in Kotlin (Java is acceptable if strongly preferred) with Android Studio. • Design clean Material-compliant screens for adding, editing and browsing tasks. • Persist data locally with Room; structure the code so a future cloud sync (e.g. Firebase) can slot in without major refactoring. • Implement a reminder engine that schedules push notifications, survives device reboots and handles recurring events such as monthly...

I’m ready to have a brand-new feature built from scratch for my mobile application, and the entire codebase needs to be written in pure Java. Performance, clean architecture, and clear inline documentation are non-negotiable because this module will slot straight into an existing codebase that already follows solid, maintainable practices. Here’s what I need from you: • A concise outline of your technical approach—how you’ll structure the code, the patterns or libraries you prefer, and the way you’ll keep the footprint lightweight on a mobile device. • A short overview of your relevant Java mobile experience, especially any instances where you created a feature end-to-end rather than extending existing code. • Your best estima...

The build must pass App Store and Google Play requirements, so remember permissions for Photos/Screenshots and Contacts access, and keep processing on-device (no external servers). Deliverables • Production-ready apps for iOS and Android • Complete, well-commented source code (Swift/SwiftUI or Objective-C for iOS, Kotlin/Java for Android—use what you are fastest with) • A brief README describing project setup, required entitlements and how to compile or archive the release builds I’ll test by taking screenshots that contain single and multiple numbers; the app should behave exactly as described above.

My legacy Java project in NetBeans no longer compiles and throws runtime exceptions whenever I try to run it. The application is supposed to read five trigger-times from a file and play an audio track exactly at each of those times, every day. Two things must happen: • Fixing packages – several old or missing packages prevent a clean build; update or replace them so Maven/Ant (whichever you prefer) produces a compile-error-free artefact. • Updating old code – bring the deprecated or broken code up to current Java standards so the app runs without warnings or runtime crashes. • Fixing startup launch – when the program auto-starts with the operating-system it should play music at the first scheduled time; right now it only works after I man...

I am looking for an expert in App Store Connect to help me overcome a "Metadata" and "Business" rejection. The app, Mind2Way, is fully developed using Flutter (Frontend) and Java Spring Boot (Backend). The Current Situation: Technical Status: The In-App Purchase (IAP) implementation is 100% functional. It has been thoroughly tested and works perfectly in Sandbox mode without any errors. The Problem: Apple is rejecting the submission due to metadata and pricing justification issues. Specifically, our "English (USA)" localization was rejected, and the review team is questioning our premium pricing model ($89.99 monthly / $399.99 yearly). Required Tasks: Metadata & Localization Fix: Rewrite the rejected English (USA) localization to be more descri...

...out—placement matches, ongoing MMR updates, a /rank lookup, and full data persistence—but the make-or-break piece is fair, dynamic matchmaking. Players must be grouped with opponents of similar rating, with the queue smart enough to widen its tolerance only when wait times get excessive. Everything has to slip neatly into the existing Bedwars1058 ecosystem; no changes to the core game, no clunky commands. Java, Spigot/Paper APIs, and solid MySQL (or equivalent) handling will all be in play. The finished module should: • Track first-ten placement games, establish an initial MMR, then adjust after every win, loss, kill or bed break (those last two should be toggleable in config). • Build and maintain balanced lobbies automatically, prioritizing equal skill...

Deliverables: 1. Clean, well-commented source code (/Kotlin or Java/) 2. Signed release builds ready for TestFlight and Google Play Internal Testing 3. Brief deployment guide covering server configuration files, protocol setup, and how to add new endpoints 4. One short video or screenshots that demonstrate kill switch and split tunneling working on an actual device If you have previously integrated v2ray or websocket transport layers...

...offline-viewing feature. The downloads must remain tied to each student’s login so that only authenticated users can view the files; once a user signs out, access to the stored videos should be revoked automatically. Because I am not sure what level of server or code access the institute can grant, the solution may involve: • Modifying the existing iOS (Swift/Objective-C) and Android (Kotlin/Java) apps to incorporate encrypted, device-bound storage or HLS with DRM. • Proposing lightweight server-side changes—perhaps token-based URLs or time-limited keys—so the institute’s current backend can authorize downloads without exposing raw files. • Implementing local logic that verifies the user’s credentials on every app launch and p...

My Java-based desktop application currently throws errors whenever a user tries to import an Excel file, and the files it exports need a small formatting tweak before they are usable. The rest of the program works well, so I’m looking for someone who can go straight to the file-handling layer, diagnose the functional bugs, and leave the UI and business logic untouched. Here’s what I need from you: • Identify and resolve the exception that appears during Excel import (the stack trace will be provided). • Adjust the export file so that matches the format required (change date in american format to eu format). • Keep the fixes confined to the existing codebase—no major rewrites—while following the project’s current build process (Mave...

...Android WebView. • I have already experimented with various WebView settings—JavaScript, media playback flags, setMediaPlaybackRequiresUserGesture =false, etc.—but nothing has stopped the pause on “home” or “recent-apps” actions. • No alternative implementations (custom players, exo-player wrappers, or different WebView engines) are in place, What I need from you: 1. A working code solution (Java or Kotlin) that lets the video continue playing when the user switches apps or locks the screen. 2. Any required permissions, service code, or MediaSession / audio-focus handling clearly documented so I can integrate it quickly. 3. A short explanation of why this approach works and any limitations on specific Android versions. Pl...

...building an Android-only application and need a clean, secure login flow that relies on one-time passwords sent strictly by SMS. Users will enter their phone number, receive the code, and gain access after successful verification—no usernames or emails involved. You’ll be responsible for wiring up the full authentication cycle, choosing a reliable SMS gateway, and writing the Android code (Kotlin or Java—your call) that: • accepts the phone number, • triggers the SMS OTP dispatch, • validates the returned code with sensible expiry and limited retries, • handles resend logic, and • stores / refreshes session tokens once the user is verified. Deliverables must include the documented source code, any backend or cloud function n...
