ADB command to toggle camera modes in android device

I am trying to figure out what is the command to load the camera app in different modes like following:

  1. Toggle between camera and video cam corder mode
  2. Toggle between front and back camera

I have used the following command to launch the camera applicaiton

adb shell am start -a android.intent.action.MAIN -n com.android.gallery3d/com.android.camera.CameraLauncher

which does launch the camera app successfully but I do no know how to toggle modes. Is there any wiki on all the different commands of ADB? the ADB documentation does not seem to talk about this.

Any ideas?

Solution

  • 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
