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 !

Can you share the stacktrace when you add the --stacktrace flag to your Gradle command? — Pierre, Mar 21 '18 at 08:05
This is caused by react-native adding uncompiled files to the merged resources directory. It got away with it with AAPT1 because the merged files didn't need to be compiled, but AAPT2 ones are compiled while being merged. React-native owners need to update their code to pass these files as input to the merge resources task instead of dumping it uncompiled into the merged directory. — Izabela Orlowska, Mar 21 '18 at 15:17
They say they fixed it in the newest version, not sure how true that is: https://github.com/facebook/react-native/pull/17967 — Izabela Orlowska, Mar 21 '18 at 15:22
Well I put the workaround for the moment... But this issue makes me sick ! — Mayoul, Mar 22 '18 at 08:58
Im ok with a workaround for now where does android.enableAapt2=false go? Could you add that to the answer for others? — slipperypete, Apr 29 '18 at 10:09

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.

Copying from the comment so it's easier to find...

This is caused by react-native adding uncompiled files to the merged resources directory. It got away with it with AAPT1 because the merged files didn't need to be compiled, but AAPT2 ones are compiled while being merged.

React-native owners need to update their code to pass these files as input to the merge resources task instead of dumping it uncompiled into the merged directory. They say they fixed it in the newest version, or at least provided a workaround: github.com/facebook/react-native/pull/17967
