Android Kitkat gallery having permission issue with camera

Question

I am using following adb command to open camera app in video recording mode directly:

adb shell am start -a android.media.action.VIDEO_CAPTURE -n  com.android.gallery3d/com.android.camera.CameraActivity

It has been all working fine until lately the comand started failing on KitKat:

C:\Users\asiaynrf>adb shell am start -a android.media.action.VIDEO_CAPTURE -n  com.android.gallery3d/com.android.camera.CameraActivity
Starting: Intent { act=android.media.action.VIDEO_CAPTURE cmp=com.android.gallery3d/com.android.camera.CameraActivity }
java.lang.SecurityException: Permission Denial: starting Intent { act=android.media.action.VIDEO_CAPTURE flg=0x10000000 cmp=com.android.gallery3d/com.android.

I have no idea why it started failing and why Gallery 3D does not have permissions to this app. Any idea?

Answer 1

That activity is not exported and is no longer accessible from outside of the app itself. Only the app can start up that activity.
