unregister broadcast receiver registered through m

问题:

Is it possible to unregister a BroadcastReceiver that has been registered through manifest? Also please let me know if it possible to ignore the BroadcastReceiver, without making any code changes, as this BroadcastReceiver is of no use to me now. Thanks.

You can disable Receiver with this code:

PackageManager pm = getPackageManager();
   ComponentName compName = 
        new ComponentName(getApplicationContext(), 
            MyReceiver.class);
   pm.setComponentEnabledSetting(
        compName,
        PackageManager.COMPONENT_ENABLED_STATE_DISABLED, 
        PackageManager.DONT_KILL_APP);

Also you can use COMPONENT_ENABLED_STATE_ENABLED to enable Receiver.
