android - Cannot Disable Broadcast Receiver -

i got logic disable/enable broadcast receiver here.

@override     public void oncheckedchanged(compoundbutton v, boolean checked) {         // todo auto-generated method stub          if (v == disableblock) {             manageblocksetting(checked);         }     }  private void manageblocksetting(boolean disable) {         log.e(tag, "disable : " + disable);         int flag = disable ? packagemanager.component_enabled_state_disabled                 : packagemanager.component_enabled_state_enabled;         componentname component = new componentname(settingactivity.this, phonecallreceiver.class);          getapplication().getpackagemanager().setcomponentenabledsetting(component, flag, packagemanager.dont_kill_app);         editsharedpreferences(storeconstantvalue.setting_disable_block, disable); } 

and in manifest.xml

<receiver android:name="com.vsmart.unocaller.blockingservice.phonecallreceiver"              android:enabled="true" >             <intent-filter>                 <action android:name="android.intent.action.phone_state" />             </intent-filter>         </receiver> 

when deploy android:enabled="false"

i can enable once. when want disable. nothing happens, can't disable it. still block incoming calls.

my device samsung galaxy s2 android 2.3.3

any help? thanks

instead of declare receiver in manifest can try registering/unregistering code. example

private class myphonestatelistener extends phonestatelistener {     @override     public void oncallstatechanged(int state, string incomingnumber) {         super.oncallstatechanged(state, incomingnumber);      } }   private myphonestatelistener phonestatelistener = new myphonestatelistener(); 

to enable

        telephonymanager.listen(phonestatelistener, listen_call_state); 

and disable

    telephonymanager.listen(phonestatelistener,             phonestatelistener.listen_none); 

where

        telephonymanager telephonymanager = (telephonymanager) getsystemservice(telephony_service);
