Packaging for android fails with gradle error

Hello,
I had a project that worked fine with 4.18. After a while and updating to 4.20, I convert in place my project (bad idea) and I can’t manage to package it anymore. Not sure this has anything to do with the 4.20 but it was the main change.
It seems that the error is linked to gradle as I get:

:app:mergeDebugResourcesC:\Users\J?r?mie\.gradle\caches\transforms-1\files-1.1\play-services-base-11.8.0.aar\ed3fd0fb06d8d84f96fc82cb75dba62a\res\drawable\common_google_signin_btn_text_disabled.xml: error: file not found.
C:\Users\J?r?mie\.gradle\caches\transforms-1\files-1.1\play-services-base-11.8.0.aar\ed3fd0fb06d8d84f96fc82cb75dba62a\res\drawable-hdpi-v4\common_google_signin_btn_icon_dark_normal_background.png: error: file not found.

And this goes on for several files that exists. It ends with some AAPT2 error:

> Error: java.util.concurrent.ExecutionException: com.android.tools.aapt2.Aapt2Exception: AAPT2 error: check logs for details

After opening the log file, I read:

I tried the different solutions from:

From my project settings:

256023-android-sdk.jpg

I tried to package by disabling gradle and using ant (by unchecking the box: enable gradle instead of ant). The packaging then completes only if “For distribution” is unchecked. However, the compiled apk crashes right when opening.

If anyone have any idea, I’m more than willing to give it a shot.

It appears that it was simply that my $USER_HOME contains non valid characters. Creating a second user with proper characters allowed me to package properly. It don’t know which update (maybe from codeworks?) made this mess, but I found a way to make it works.

I have the same problem, but my path seems okay.

I don’t understand what could be the problem. It was working fine all the time.

what did you do to make it work
and can you give me screenshot of sdkconfig after you did this

I have the same problem too with 4.21.1 and Codeworks 1R7. Exact same error in my log file. I tried deleting the license key and accept it. Didn’t help. My user home dir is fine. No special characters.

Has any one able to fix this. It’s like the blue screen of death. While Epic is enjoying the holidays we are going to enjoy fixing their creation.

I had a similar error. Added icon_round.png to /Intermediate/Android/arm64/res/drawable. (Just duplicated icon.png and renamed) Works fine.
