Answer 1

I Got AutoFlash light with below simple Three Steps.

• I just added Camera and Flash Permission in Manifest.xml file

• In your Camera Code do this way.

  //Open Camera
  Camera  mCamera = Camera.open(); 
  
  //Get Camera Params for customisation
  Camera.Parameters parameters = mCamera.getParameters();
  
  //Check Whether device supports AutoFlash, If you YES then set AutoFlash
  List flashModes = parameters.getSupportedFlashModes();
  if (flashModes.contains(android.hardware.Camera.Parameters.FLASH_MODE_AUTO))
  {
       parameters.setFlashMode(Parameters.FLASH_MODE_AUTO);
  }
  mCamera.setParameters(parameters);
  mCamera.startPreview();
  

• Build + Run —> Now Go to Dim light area and Snap photo, you should get auto flash light if device supports.
