Flutter crashing with just_audio package: java.lang.ClassNotFoundException: Didn't find class "com.ryanheise.audioservice.AudioServiceActivity"

Question

I am using just_audio package and the flutter app has started crashing.

✓  Built build/app/outputs/flutter-apk/app-debug.apk.
E/AndroidRuntime(18755): FATAL EXCEPTION: main
E/AndroidRuntime(18755): Process: com.zenbition.zense_timer, PID: 18755
E/AndroidRuntime(18755): java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{com.zenbition.zense_timer/com.ryanheise.audioservice.AudioServiceActivity}: java.lang.ClassNotFoundException: Didn't find class "com.ryanheise.audioservice.AudioServiceActivity" on path: DexPathList[[zip file "/data/app/com.zenbition.zense_timer-YIaQtX7NxpYwWAO2yfHEHQ==/base.apk"],nativeLibraryDirectories=[/data/app/com.zenbition

When the app loads, it crashes after 1 second.

Prior to crashing just_audio stopped playing sound (but wasn't throwing any errors).

I have removed and reinstalled just_audio and run flutter clean / flutter pub get with full restart, but can't fix the error:

Here is the full error code.

Answer 1

Ok so I found the answer, and was my silly mistake. Posting answer in case anyone does the same.

In the Activity Tag in the Android Manifest (android>app>src>main>AndroidManifest.xml) I had changed the android:name (as was going to use another audio package which required this step).

So to fix this error just needed to change back to android:name=".MainActivity".
