android - How to get contact name when receiving SMS -


i have following code receive sms , trying contact name.

package com.example.smstest;  import android.content.broadcastreceiver; import android.content.context; import android.content.intent; import android.database.cursor; import android.net.uri; import android.os.bundle; import android.provider.contactscontract; import android.provider.contactscontract.phonelookup; import android.telephony.smsmessage; import android.widget.toast;  public class smsreceiver extends broadcastreceiver {     private sqliteadapter mysqliteadapter;      @override     public void onreceive(context context, intent intent) {         mysqliteadapter = new sqliteadapter(context);         mysqliteadapter.opentoread();          message message = null;          bundle extras = intent.getextras();         if (extras == null)             return;          object[] pdus = (object[]) extras.get("pdus");         (int = 0; < pdus.length; i++) {             smsmessage smessage = smsmessage.createfrompdu((byte[]) pdus[i]);             string sender = smessage.getoriginatingaddress();             string body = smessage.getmessagebody().tostring();              message = mysqliteadapter.createmessage(sender, body);              // custom intent used broadcast             intent in = new intent("smsmessage.intent.main").putextra(                     "get_msg", sender + ":" + body);              // display toast whenever there sms.             toast.maketext(context, body, toast.length_long).show();              uri personuri = uri.withappendedpath( contactscontract.phonelookup.content_filter_uri, smessage.getoriginatingaddress());                cursor cur = context.getcontentresolver().query(personuri, new string[] { phonelookup.display_name }, null, null, null );                if( cur.movetofirst() ) {                            int nameindex = cur.getcolumnindex(phonelookup.display_name);                             string personname = cur.getstring(nameindex);                            toast.maketext(context, personname, toast.length_long).show();             }             cur.close();              // can place check conditions here(on sms or             // sender)             // , send broadcast             context.sendbroadcast(in);              // used abort broadcast , can used silently             // process incoming message , prevent further being             // broadcasted. avoid this, not way program             // app.             this.abortbroadcast();         }     } }

this code have added cause app crash:

uri personuri = uri.withappendedpath( contactscontract.phonelookup.content_filter_uri, smessage.getoriginatingaddress());    cursor cur = context.getcontentresolver().query(personuri, new string[] { phonelookup.display_name }, null, null, null );    if( cur.movetofirst() ) {                int nameindex = cur.getcolumnindex(phonelookup.display_name);                 string personname = cur.getstring(nameindex);                toast.maketext(context, personname, toast.length_long).show(); } cur.close();

i modified code answer on link.

now app crashes when receiving sms.

try code

in broadcast receiver

 public class smsreceiver  extends broadcastreceiver{   string str = "";      string no = ""; @override public void onreceive(context context, intent intent) {     // todo auto-generated method stub       bundle bundle = intent.getextras();           smsmessage[] msgs = null;         if (bundle != null)         {             //---retrieve sms message received---             object[] pdus = (object[]) bundle.get("pdus");             msgs = new smsmessage[pdus.length];                         (int i=0; i<msgs.length; i++){                 msgs[i] = smsmessage.createfrompdu((byte[])pdus[i]);                                  str += msgs[i].getmessagebody().tostring();                 str += "\n";                     no = msgs[i].getoriginatingaddress();                  //resolving contact name contacts.                 uri lookupuri = uri.withappendedpath(phonelookup.content_filter_uri, uri.encode(no));                 cursor c = context.getcontentresolver().query(lookupuri, new string[]{contactscontract.data.display_name},null,null,null);                 try {                     c.movetofirst();                  string  displayname = c.getstring(0);                 string contactname = displayname;                    toast.maketext(context, contactname, toast.length_long).show();                  } catch (exception e) {                     // todo: handle exception                 }finally{                     c.close();                 }              }         }     } }

you have register broadcast receiver in manifest intentfilter

    <receiver android:name="smsreceiver">           <intent-filter>               <action android:name= "android.provider.telephony.sms_received" />          </intent-filter>       </receiver>

also have add user permission like

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

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
