I have written an accessibility service and I want the service to be stopped/killed once it receives an accessibility event (i.e. in method onAccessibilityEvent ). Can this be done? I have tried to kill using kill process as below but it is not working. unbindService(mSvcConn); android.os.Process.killProcess(android.os.Process.myPid()); I have given the below permission in AndroidManifest.xml <uses-permission android:name="android.permission.KILL_BACKGROUND_PROCESSES" /> I know that accessibility service cannot be started programmatically but can't it be stopped/killed either? alanv An

We're looking to send an accessibility event (which would be picked up by TalkBack etc.) which isn't linked to a view.
