Error:Execution failed for task ':app:packageDebug'. > !zip.isFile()
Clean and Rebuild project should work. It work for me. Look at this: https://code.google.com/p/android/issues/detail?id=230211
Regarding this:
Error:Execution failed for task ':app:packageDebug'.> !zip.isFile()
I solved it by deleting the build
project and running again.
Hope this helps.
Its very simple just run ./gradlew clean
If you are using Cordova or Ionic Framework run following commands
cd platforms/android
./gradlew clean
Its easy fix.
