Error Execution failed for task ':app:mergeReleaseResources' building APK

Question

After trying to build APK once and fixing an error, I got an error executing ./gradlew assembleRelease again: Execution failed for task ':app:mergeReleaseResources' building APK

Answer 1

Had the same error. Just clean your project and make a fresh build. Works for me with sdk 33.

Sometime invalidate caches and restart helps as well.

Answer 2

If you are facing this error from

\android\app\src\main\res\mipmap-xxxhdpi\splash.png

change it to jpg extension

\android\app\src\main\res\mipmap-xxxhdpi\splash.jpg

Answer 3

I changed .png to .jpg in drawable and it worked for me.

Answer 4

I just deleted the drawable-* dirs as well raw dir from

android/app/src/main/res/ and it worked.

Answer 5

As addition to accepted answer, if there is a "raw" folder in the same directory, also you must delete that.

Answer 6

Exactly problem occurred when I tried to build once, it has created drawable dirs. I was facing following issue:

Execution failed for task ':app:mergeReleaseResources'.

java.util.concurrent.ExecutionException: com.android.builder.internal.aapt.v2.Aapt2InternalException: AAPT2 aapt2-3.3.0-5013011-windows Daemon #0: Unexpected error during compile 'E:\project\ionic\uvparentlan0.4\platforms\android\app\src\main\res\drawable-land-xxxhdpi\screen.png', attempting to stop daemon. This should not happen under normal circumstances, please file an issue if it does.

Solution: I delete all drawable directories named "drawable-port-*****"

Now Build again " ionic cordova build --release android "

Answer 7

Sometimes it's a result of a duplicate file. Reading the error log, it seemed that I had a duplicate file name (two files with the same name). The issue resolved by removing one of the files (from a previous build if I remember it right).

Answer 8

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-*
