react native - Generate signed APK - Android Failed to execute aapt

Question

I m trying to generate a signed APK for android with react-native. If the debug's build works well, when I try to launch the ./gradlew assembleRelease to create the signed APK for android, I get this error =>

Task :app:processReleaseResources
Failed to execute aapt
com.android.ide.common.process.ProcessException: Failed to execute aapt

I know that I can use the android.enableAapt2=false flag and it works well (for create the signed APK, I tried it), but I don t want to use this options since it's just a workaround and won t works for ever, and all of the threads that I read were suggesting that... :/

There isn t any others options ?

Thanks for your help !

Answer 1

For me disabling aapt2 wasn't enough. What did work was going to android/app/src/main/res and looking in all the drawable folders for png files other than the launch_screen.png. Once I deleted all these files, the problem was solved.
