android - How to get unread SMS when just receive it? -

i'm building unread sms relay application. there phone , b, when receives sms , no 1 read it, application relay b. find when receives sms, there system notification display. contentobserver's onchange() method called until disappear notification. should unread sms when receive it?

contentobserver:

public newincomingcontentobserver(handler handler, application   application) {     super(handler);     this.mapplication = application;   }    @override   public void onchange(boolean selfchange) {     system.out.println(selfchange);     super.onchange(selfchange);     uri uri = uri.parse(sms_uri_inbox);     mmessagelistener.onreceived(this.getsmsinfo(uri, mapplication));   }    /**    * newest sms    */   private smsinfo getsmsinfo(uri uri, application application) {     ...   }    public interface messagelistener {     public void onreceived(smsinfo smsinfo);   }    public void setonreceivedmessagelistener(           messagelistener messagelistener) {     this.mmessagelistener = messagelistener;   } } 

service:

public class smslistenerservice extends service {   public static final string uri = "content://sms/inbox";    public smslistenerservice() {   }    @override   public ibinder onbind(intent intent) {     throw new unsupportedoperationexception("not yet implemented");   }    @override   public int onstartcommand(intent intent, int flags, int startid) {     //register observer     newincomingcontentobserver smscontentobserver =             new newincomingcontentobserver(new handler(), getapplication());      this.getcontentresolver().registercontentobserver             (uri.parse(uri), true, smscontentobserver);      smscontentobserver.setonreceivedmessagelistener(new newincomingcontentobserver.messagelistener() {       @override       public void onreceived(smsinfo smsinfo) {         system.out.println(smsinfo);       }     });     return start_not_sticky;   } } 

an example borrowed (https://github.com/pyo25/phonegap-sms-reception-plugin), example phonegap plugin can still use it:

public class smsreceiver extends broadcastreceiver {     public static final string sms_extra_name = "pdus";      // broadcast boolean used continue or not message broadcast     // other broadcastreceivers waiting incoming sms (like native sms app)     private boolean broadcast = false;      @override     public void onreceive(context ctx, intent intent) {          // sms map intent         bundle extras = intent.getextras();         if (extras != null)         {            // received sms array             object[] smsextra = (object[]) extras.get(sms_extra_name);              (int i=0; < smsextra.length; i++)             {                 smsmessage sms = smsmessage.createfrompdu((byte[]) smsextra[i]);                      string formattedmsg = sms.getoriginatingaddress() + ">" + sms.getmessagebody();              }              // if plugin active , don't want broadcast other receivers             if (!broadcast) {                 this.abortbroadcast();             }          }     } } 

and in androidmanifest:

<uses-permission android:name="android.permission.receive_sms"/>
