Toggling flash modes without restarting camera

[Mohit Shetty]

Is there any way to toggle the flash mode without restarting the camera or perhaps calling cameraProvider.unbindAll and cameraProvider.bindToLifecycle again. I tried manually changing the flash mode from the objects orginally passed to the bind lifecycle method, but nothing it seems to follow the old config, maybe because it's copied and passed to the native APIs.

Thanks in advance.

Hi Mohit, 

Please try ImageCapture.setFlashMode.  It allows apps to change flash mode without rebinding again. 

For example, 

val imageCapture = ImageCapture.Builder().build()

cameraProvider.bindToLifecycle(lifecycle, cameraSelector, imageCapture...) 

// When flash option is changed,  call the API to configure . 

imageCapture.setFlashMode(..).  

If this doesn't work, then it is probably a bug.
