sms - Android: pass variables from Activity to BroadcastReceiver -

i have problem passing throught variable activity broadcastreceiver... here code:

here broadcast receiver code... try catch sms 1 phone number have got activity...

public class smsmonitor extends broadcastreceiver  {     private static final string action = "android.provider.telephony.sms_received";     public static string phone_number = "";     public static string msg_body = "";     public static final string sms_extra_name = "pdus";      @override     public void onreceive(context context, intent intent)     {         string phone = intent.getextras().getstring("trusted_num");          if (intent != null && intent.getaction() != null && action.comparetoignorecase(intent.getaction()) == 0)         {             object[] pduarray = (object[]) intent.getextras().get("pdus");             smsmessage[] messages = new smsmessage[pduarray.length];              (int = 0; < pduarray.length; i++)             {                 messages[i] = smsmessage.createfrompdu((byte[]) pduarray[i]);             }              phone_number = messages[0].getdisplayoriginatingaddress();             msg_body = messages[0].getmessagebody();              system.out.println("phone number: "+phone_number);             system.out.println("phone entered: "+phone);         }     } } 

here activity code:

public class settings extends activity implements onclicklistener{      private button btn_save;     private edittext txt_phone;      @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_settings);          //set save button         btn_save = (button)findviewbyid(r.id.btn_save);         txt_phone = (edittext)findviewbyid(r.id.et_phone);          btn_save.setonclicklistener(this);     }      @override     public boolean oncreateoptionsmenu(menu menu) {         // inflate menu; adds items action bar if present.         getmenuinflater().inflate(r.menu.activity_settings, menu);         return true;     }      @override     public void onclick(view v)      {         if (v == btn_save)         {             try             {                 string phone_num = txt_phone.gettext().tostring();                 intent = new intent(settings.this, smsmonitor.class);                 i.putextra("trusted_num", phone_num);                 sendbroadcast(i);             }             catch(exception e)             {                 system.out.println("error: "+e.getlocalizedmessage());             }         }     }  } 

in code have text field entering phone number, need pass broadcastreceiver intent.putextra() method, in logcat see, variable didnot pass:

07-25 18:43:57.382: i/system.out(14245): phone number: +37129690449 07-25 18:43:57.382: i/system.out(14245): phone entered: null 

so doing wrong here?

upd maybe code not correct, works me...

public void onreceive(context context, intent intent)     {         phone = intent.getextras().getstring("trusted_num");//get trusted phone number settings screen          //receive sms         if (intent != null && intent.getaction() != null && action.comparetoignorecase(intent.getaction()) == 0)         {             object[] pduarray = (object[]) intent.getextras().get("pdus");             smsmessage[] messages = new smsmessage[pduarray.length];              (int = 0; < pduarray.length; i++)             {                 messages[i] = smsmessage.createfrompdu((byte[]) pduarray[i]);             }              phone_number = messages[0].getdisplayoriginatingaddress();             msg_body = messages[0].getmessagebody();              system.out.println("phone number: "+phone_number);         }         //check if number not null         if (phone != null && phone != "")         {             system.out.println("phone entered: "+phone);         }      } } 

you can't pass intent broadcast receiver. "there no way broadcastreceiver see or capture intents used startactivity()" https://developer.android.com/reference/android/content/broadcastreceiver.html

i had similar issue while , solved using combination of intentservices , activities. have restructure program fit these guidlines
