Thanks for reaching out !  

Could you provide the following information ? That would be helpful for us to find the root cause of it. 
1) Is it 100% reproducible or how frequently does it happen ?

2) on what devices were you using ?

3) Do you have more complete logs for the issue ?

Just to double check. 

You can reproduce this issue on Oppo A3s,Xiaomi Mi A2 Lite, and also emulator API 28, and it's 100%,  right ?

In this case, do you mind testing it again using the latest version 1.3.0-beta02 to see if it is fixed in the later version ?  

BTW,  the exception   "android.view.ViewRootImpl$CalledFromWrongThreadException: Only the original thread that created a view hierarchy can touch its views." can be avoided by running the View-related codes in the UI thread.  For example, you can pass the main thread executor (e.g, ContextCompat.getMainExecutor(context)) in the takePicture() call or post the runnable via runOnUiThread.
