Hi! I am new here and hope that I post this in the right place!
I am trying to get the Android-FPVDemo running. I cloned the repository and tried to run the app on my phone. The App instantly crashes.
The app crashes when - it is connected to my computer / AndroidStudio
- to the DJI remote and
- not connected at all.
Phone: Samsung Galaxy S22 Ultra
Android: Android 13 Android Studio: Android Studio Dolphin | 2021.3.1 Patch 1 | Runtime version: 11.0.13+0-b1751.21-8125866 amd64 Drone: DJI Phantom 4 Pro V2

I also had this problem when following your tutorial for the UXSDK Demo and creating the App from scratch.
Thanks!
