This issue occurs because the native .so libraries required by TUICallKit and TRTC SDK are not being included in the APK during the build process. To resolve this:

a.Go to Build > Clean Project in Android Studio.

b.Then, go to Build > Rebuild Project.

c.Uninstall the existing app from your device or emulator.

d.Reinstall the app after rebuilding.

This ensures that the native libraries are correctly packaged into the APK.
