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"/>

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
