ADB command to toggle camera modes in android devi

问题:

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?

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

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?

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.
