Hi!
I’ve a strange issue when debugging my application from Android Studio using emulator or building APK and installing the APK to my phone. Only white screen appears after the splash screen. No crashing, just white screen.
What’s interesting about this error when using ionic capacitor run android -l --host=my_local_ip my app works perfectly fine both on Android emulator and my Phone (Xiaomi Redmi 6). Web browser debug also works fine.
What I’ve done:
- ionic capacitor build android
- Debug or build from android studio
Logcat from android studio when debugging (Verbose mode):

I don’t have too much experience with Android studio & Android development, so maybe I’m missing something silly.
Thanks in advance!
Also sorry for my bad English, not a native speaker!
