I will diagnose and fix issues in your Android application and help improve its stability, performance, and reliability.

I can help with:

App crashes and unexpected errors

Android Studio build and Gradle issues

Kotlin and Java bugs

Firebase integration problems

API and server connection errors

Login and registration issues

UI/layout problems

APK/AAB build errors

Target SDK and dependency updates

Google Play release-related issues

App performance improvements

Existing app updates and maintenance

I will first review the issue, identify the cause, implement the required fix, and test the app before delivery.

For larger applications or multiple issues, please message me so we can define the scope before starting.
