Answer 1

You can use following though:

Intent action = new Intent("android.media.action.IMAGE_CAPTURE");  
        action.putExtra("android.intent.extras.CAMERA_FACING", 1);

You can use adb command "am start" . Please read following: How to run a specific Android app using Terminal?

Answer 2

For KK:

adb shell am start -a android.media.action.STILL_IMAGE_CAMERA --ei android.intent.extras.CAMERA_FACING 1

Change the id 0 or 1 for front and back camera.

Answer 3

You can pass an Extra with an integer value using the --ei flag to the am start command

Front Camera

adb shell am start -a android.media.action.IMAGE_CAPTURE --ei android.intent.extras.CAMERA_FACING 1

Back Camera

adb shell am start -a android.media.action.IMAGE_CAPTURE --ei android.intent.extras.CAMERA_FACING 0
