I need the Sarthak attendance app decompiled, modified, and re-compiled so that it quietly fakes location updates while blocking every developer-mode or mock-location check the app currently performs. After the patch, the only feature I still care about is reliable mock GPS reporting; everything else can be stripped or left untouched as long as it does not break the sign-in flow. Key requirements • The app must broadcast random but believable coordinates inside a user-defined radius that I can hard-code before build time. • Any code paths that call Settings.Secure.DEVELOPMENT_SETTINGS_ENABLED, isFromMockProvider(), or similar APIs should return values that hide the fact a mock provider is active. • No on-screen warnings, root prompts, or “developer mode detected” pop-ups may appear. • The final APK must install and run on Android 9–13 without requesting extra permissions beyond the original set. Deliverables 1. Patched, install-ready APK signed with a test key. 2. Full diff or Smali/Java source so I can see exactly what changed. 3. Short build notes showing the tools and commands you used (apktool, JADX, smali/baksmali, etc.) so I can reproduce the build if the app updates. I will test by installing the app, enabling no system-wide mock settings, and watching the attendance check read the spoofed, shifting coordinates. If that passes without triggering any anti-tamper message,

Dear Client, I am excited about your attendance app modification project. I have strong experience decompiling, patching, and recompiling Android apps with mock location bypass logic. --- **What is your target of this project?** Decompile, modify, and recompile the Sarthak attendance app to report believable fake GPS coordinates—bypassing all mock-location checks (isFromMockProvider, Developer Settings) without triggering warnings. --- **Core skills:** - APK Decompilation (apktool, JADX) - Smali / Java Modification - Mock Location Bypass - Android 9-13 Compatibility - APK Signing & Testing --- **How I solve & deliver:** 1. Decompile APK and locate mock-check code. 2. Patch isFromMockProvider and Developer Settings checks. 3. Inject random coordinate generator within hard-coded radius. 4. Recompile and sign APK with test key. 5. Deliver patched APK, source diff, and build notes. --- Thank you for your time. I am confident I can deliver a working, undetectable patch. Best Regards

Hi, What caught my attention wasn't the tech stack - it was the way you described the problem. It sounds like you've already thought through what you need, and you're looking for someone who can execute carefully rather than someone who'll overpromise. I read your requirements from start to finish, and before discussing solutions, I'd like to understand a couple of implementation details so we're aligned from day one. I prefer keeping clients updated with small milestones, explaining technical decisions in plain language, and delivering code that's easy to maintain rather than just "works for now." If we work together, my priority will be to understand your end goal first, identify any edge cases early, and build the solution in a way that avoids surprises later in the project. Would you be available for a quick call to discuss this further? Thanks, Akash

I understand that you need the Sarthak attendance app modified to provide stealthy mock location updates while avoiding detection by any anti-tamper measures. This requires careful decompilation, modification, and recompilation to ensure seamless functionality. To achieve this, I would focus on analyzing the app's code to identify and modify the relevant checks for mock locations. I’ll implement a system that generates random coordinates within a specified radius while ensuring that the app remains undetectable. I have experience working with APK modification and have previously completed similar projects that involved bypassing location checks and maintaining user privacy. Would you like to discuss any specific requirements or preferences for the random coordinate generation? **Why this approach:** - Directly addresses the specific needs outlined in your project description. - Shows understanding of technical requirements and previous related experience. - Invites further dialogue, encouraging a response.

Hi, I read through your requirements carefully, and I understand exactly what you're looking for. I have strong experience working with Android applications, Java, reverse engineering, APK modification, and rebuilding apps while keeping the original functionality intact. Before starting, I'll first analyze the APK to understand how the location checks and anti-tamper mechanisms are implemented. I'll document every change made so you'll receive both the modified source/diff and clear build notes, making it easy to reproduce the build if the app is updated in the future. You'll receive: * Patched, install-ready APK * Source changes (Smali/Java diff) * Build and signing instructions * Testing across the requested Android versions to ensure the app remains stable I believe in keeping clients updated throughout the project, so you'll receive progress updates instead of waiting until the end. If there are any edge cases or compatibility concerns during testing, I'll address them before delivery. I'm available to start immediately and can complete this within the proposed timeline. Looking forward to working with you. Thanks, Ishant Gupta
