Error Execution failed for task ':app:mergeReleaseResources' building APK
The problem occured becaused when I tried to build once, it has created drawables dirs on android/app/src/main/res/. Then when I tried on second time, it has shown me this error Execution failed for task ':app:mergeReleaseResources' building APK
I just deleted the drawable-* dirs and it worked.
Hope it helps!
rm -rf android/app/src/main/res/drawable-*
As addition to accepted answer, if there is a "raw" folder in the same directory, also you must delete that.
I just deleted the drawable-* dirs as well raw dir from
android/app/src/main/res/ and it worked.
