React Native android build FAILD :app:mergeReleaseResources

Question

The App is working fine, in fact I have built 2 release APKs. This time I modified the code and came to do ./gradlew assembleRelease and I got the following error:

Error

FAILURE: Build failed with an exception.

What went wrong: Execution failed for task ':app:mergeReleaseResources'.

Expectation

To generate a healthy APK ready to publish.

Extra Info

I have done the signing and the .keystore in the right place ../android/app
Updated ../android/gradle.properties as instructed

Here is the complete stacktrace:

Please don’t post screenshots of your errors. Copy your error, edit your question and paste them in. — Andrew, Mar 08 '19 at 06:45
@Mohammed Al Joohi, try clearing your build folder and stop any debuggers/emulators attached and then try the build. — Furqan Hameedi, Mar 08 '19 at 06:45
Please include the whole stacktrace from the '[Screenshot from the Scan3](https://i.stack.imgur.com/T5bPa.png)' image. Have you tried: `/gradlew clean assembleRelease`? — Andreas Lorenzen, Mar 08 '19 at 06:49
@AndreasLorenzen I have posted it in the post. Thank you for putting your time into this with the post edits, much appreciated. — Mohammed Al Joohi, Mar 08 '19 at 06:55
It looks like it may not be able to create the output directory? Check what is going on here: `OutputDirectoryCreatingTaskExecuter.java:51`. Can you clean the target location manually? — Andreas Lorenzen, Mar 08 '19 at 06:59
I did clean the previous release APK if that’s what you mean Sir. — Mohammed Al Joohi, Mar 08 '19 at 07:00

I believe this could be a duplicate of this question:

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.

To remove the directory drawable--*:

rm -rf android/app/src/main/res/drawable-*

there is no drawable folder inside res – Chanrithisak Phok Dec 29 '20 at 01:15 — Chanrithisak Phok, Dec 29 '20 at 01:15

enter image description here

There is no drawable folder inside res, still the error occurs.
While running the emulator the build is successful and emulator works fine but I couldn't take release apk because of build failure.
