My Android app, written entirely in Java, is currently crashing the moment it launches. I need an experienced mobile developer who can jump into the existing codebase, track down the root cause, and deliver a clean, tested fix as soon as possible. Here’s what I expect: • Diagnose the startup crash quickly—logcat traces point to the main Activity but I need a full root-cause analysis. • Patch the offending code while keeping the current architecture intact. • Supply a brief changelog and the updated source (Git diff or zipped folder) along with a working APK for verification. • Test the new build on at least one device and one emulator to confirm the app now opens consistently without a crash. Acceptance criteria: the app launches to its home screen on every test, no new errors appear in logcat, and all existing functionality remains unaffected. If you’ve handled similar Java/Android crash fixes before and can turn this around quickly, let’s get started.
