I have a lightweight Android attendance-marking app that halts the moment it notices the device’s Mock Locations developer option. The codebase is small and—frankly—light on security, so I expect the fix to be straightforward: track down the section that runs the developer-option check and remove or bypass it so the app launches and functions normally even when Mock Locations is switched on. You will receive the current APK plus the un-obfuscated Java/Kotlin source. I’m fine with any clean approach—editing the existing code, injecting a small patch, or using Smali/Frida to prove the point—so long as the final APK installs and runs on Android 10 through 14 without triggering its current “developer options detected” message. Please return: • Updated source with the check disabled • A signed, install-ready APK for testing • Brief notes on what was changed so I can maintain the fix in future builds. If you have questions about the code layout or need a particular test scenario, let me know and I’ll supply it right away.

Since you’re providing the unobfuscated Java/Kotlin source, I’d fix this at source level rather than relying on a fragile Smali or Frida workaround. I’ll trace where the Mock Location/developer-setting check is triggered, including startup and attendance/location flows, then disable only that restriction without interfering with the app’s normal GPS or attendance functionality. After rebuilding, I’ll test the launch and attendance flow with Mock Locations enabled and verify compatibility across the targeted Android versions. You’ll receive the updated source, signed test APK, and a short note identifying exactly what was changed for future builds. Is the “developer options detected” check triggered immediately at startup, or only when the user tries to mark attendance?

I need to be straightforward with you here rather than write a winning bid, because this is a project I cannot take on, and I want to explain why clearly. What you are describing is disabling a security control that exists specifically to prevent location spoofing in an attendance system. Mock location detection is not a bug in your app. It is a deliberate safeguard ensuring that employees cannot fake their physical presence by feeding the app a fabricated GPS coordinate. Removing it does not fix a problem. It removes the integrity guarantee the app was built to provide. If I delivered this, the resulting APK would allow any user to mark themselves as present at a location they are not actually at. That causes real harm to whoever relies on that attendance data, whether that is an employer, a school, a contractor, or a compliance process. I would be glad to help you with legitimate adjacent work. If the check is triggering false positives on certain devices or legitimate developer hardware, I can help you refine the detection logic so it is more accurate. If you need to build a test environment that bypasses checks only in a clearly sandboxed debug build, that is also a reasonable engineering conversation. Is either of those the actual underlying problem you are trying to solve?

Hi, I can help trace the Android developer-option check in the provided Java/Kotlin source, remove the unintended attendance-app restriction cleanly, and validate the resulting build across Android 10–14. I’d first identify where the Mock Locations detection is triggered, update the relevant logic rather than applying an unnecessary runtime patch, then test installation, attendance marking and the affected startup flow with Mock Locations enabled. I’ll provide the updated source, signed APK and concise maintenance notes documenting the change. Best Regards, Aman

Hi, I can modify your Android attendance app to remove the existing Mock Locations/developer-option check while keeping the rest of the application behavior unchanged. I’ll review the Java/Kotlin source, identify the detection logic, implement a clean maintainable change, and test the resulting build across Android 10–14. I’ll verify normal launch and attendance functionality with Mock Locations enabled, then provide the updated source, signed install-ready APK and concise maintenance notes. I’ll prioritize a source-level fix over Smali/Frida where possible so the change remains easy to maintain in future builds.

Hello, I can help modify your Android attendance app so its location-validation behavior is maintainable and suitable for legitimate QA/testing across Android 10–14. I have 5+ years of experience in Android development, Java/Kotlin, application debugging, security-focused testing, and release builds. I’ll review the existing Java/Kotlin source and identify how the Mock Locations detection is currently implemented. Instead of patching around the security control, I can restructure it with a clearly separated configuration/test mode so authorized development and QA scenarios can be tested without affecting the production validation flow. I’ll verify the attendance workflow, lifecycle behavior, location handling, and compatibility across Android 10–14. The final delivery can include updated source, a signed install-ready APK for the agreed test configuration, and concise maintenance notes explaining the relevant changes and build setup. I’m comfortable working from your existing APK/source and milestone-based delivery, with a small paid test task if required. Best Regards, Shailender

Hi, the issue with your Android attendance-marking app halting when it detects Mock Locations is likely due to a specific check in the code. I'd approach this by tracking down the section that runs the developer-option check and removing or bypassing it. This should allow the app to launch and function normally even when Mock Locations is switched on. In my experience, the common mistake here is not properly handling the developer options, which can lead to unnecessary checks and restrictions. I'll set up a clean approach to edit the existing code and disable the check, and you can expect a straightforward fix that allows the app to run on Android 10 through 14 without triggering the "developer options detected" message.
