I need help, my app is bigger than 25mb

Of course, that is possible. Stepps to build an APK > 20 and < 100 MB (Play Store limit): remove some big files (png, jpg, mp3) from the assets (< 20 MB! / better < 5 MB) build APK decompile APK reinsert the missing files to the assets recompile your app sign APK If you kown how it works, it takes about 1 min.
