Read the stack-trace locations in androidx.camera.view.CameraController.hasCamera and com.luck.picture.lib.camera.CustomCameraView.toggleCamera. Reproduce the camera-toggle flow on the reported Samsung Galaxy Grand Prime running Android 5.0.2 and trace the initialization timing. Done means toggling the camera no longer throws this IllegalStateException before initialization completes.
