Android Question Camera2 crashing

[Daica]

I have not touched any code related to the Camera2 code and now whenever I open the camera page, the app crash with the following error:

** Activity (main) Resume **
** Activity (main) Pause event (activity is not paused). **
** Activity (main) Resume **
** Activity (main) Pause event (activity is not paused). **

I didn't touch the code for the camera, so why is it happening all of a sudden?
Anyone got any ideas?

Anyone got any ideas?

NO! How should we know? ONLY you have the crashing source. We can not guess what you are doing.
Upload a small project showing the problem.

Check the camera I'd

I finally found the cause.
The app was crashing and I was getting that error because I was trying to log the available preview sizes.

For Each ps As CameraSize In cam.SupportedPreviewSizes
    Log("Width: " & ps.Width & " Height: " & ps.Height)
Next

Removing this code makes the app works again...
