        </intent-filter>
    </receiver>

now i want it to dynamically unregister by switch. when the switch is off it showed not detect incoming SMS.How i could do this. Please help me

Answer 1

Since you can not change the manifest content dynamically.

You can use shared Preference to store the switch state as true or false .

Then inside the onRecieve , get the state from the preference and then perform your action only when state is true else do not perform.

Answer 2

You can check a configuration value in your manifest-registered receiver and do nothing when appropriate. Example:

public class MyBroadcastReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        if (myBroadcastReceierIsOff) {
            return;
        }
        (...)
    }
}
