I’ve managed to upload the native debug symbols. But I’am not sure yet if it works since I have to check the stack traces later.
According to Developer Android native-crash-support the debug symbols are created by gradle.
After a search in the project folder I found this folder:
\Unreal Projects\[project Name]\Intermediate\Android\gradle\app\build\intermediates\stripped_native_libs\release\out\lib
In there are the mentioned folders from the android developer documentary.
I packaged these 4 folders into a zip and uploaded this zip to google play console. The console accepted the upload.
So this seems to be the solution. You might have to activate “include debug files” in project settings. But I’am not sure.
