Execution failed for task ':app:packageDebug&#

问题:

Without any changes in my code, suddenly i get this error when I try to run my app:

• What went wrong: Execution failed for task ':app:packageDebug'. com.android.builder.packaging.PackagerException: java.io.IOException: Failed to read zip file 'C:\Users\Eliran\AndroidStudioProjects\Forum\app\build\outputs\apk\app-debug.apk'.

I have no idea why its trying to read the apk as zip file.

• If I restart Android Studio, I can run the app once and then It happens again.

For me it helps (for now) when I Exit Android Studio, next I used Windows Task Manager (Ctrl + Shift + Esc) and kill process Java(TM) Platform SE binary and delete that file manually. After that I run Android Studio again, click on the Clean Project (there can be an error with app:clean, but you can run Android Studio again) and next click Make Project - after that of course Run 'app' button in Android Studio.

I try manual delete file, but the SO inform: the file "app-debug.apk" is in use by "OpenJDK Platform Binary". Then I kill "OpenJDK Platform Binary" and this worked.
