Android texting program, but no effect.

============ Problem Description ============

This code is the activity inside the layout of I do not post, I set the toast have been reported, but the text message still can not be sent out.

Package com.example.message;import android.app.activity;import android.app.pendingintent;import  android.content.intent;import android.os.bundle;import android.telephony.smsmanager;import  android.util.Log;import android.view.Menu;import android.view.View;import  Android.view.view.onclicklistener;import android.widget.button;import android.widget.edittext;import  android.widget.Toast;public class MainActivity extends Activity {public  button send;public edittext number,message; @Overrideprotected  void oncreate (Bundle  savedinstancestate)  {super.oncreate (savedinstancestate); Setcontentview (R.layout.activity_main); send  =  (Button) This.findviewbyid (r.id.send);number =  (EditText) This.findviewbyid (R.id.number); message =  (EditText) This.findviewbyid (r.id.msg); Send.setonclicklistener (New onclicklistener () {@ Overridepublic void onclIck (view arg0)  {// todo auto-generated method stubsendmessage ();});} Public void sendmessage () {String pnumber = number.gettext (). toString (). Trim (); String msg = message.gettext (). toString (). Trim ();   pendingintent sentintent  = pendingintent.getbroadcast (This, 0, new intent (),  0), if ("". Equals (msg) | | "". Equals (Pnumber)) {Toast.maketext (this,  "need to fill in the number, cut text message content cannot be empty",  toast.length_long). Show (); ELSE{LOG.I ("Message",  "Recipient:" +pnumber+ "   info:" +msg "); Smsmanager sms = smsmanager.getdefault (); Sms.sendtextmessage (pnumber,  "13652179825",  Msg, sentintent, null);  toast.maketext (this,  "sent successfully! ",  toast.length_long). Show ();}} @Overridepublic  boolean oncreateoptionsmenu (Menu menu)  {// inflate the menu ;  this adds items to the action bar if it is&nbsP;present.getmenuinflater (). Inflate (r.menu.main, menu); return true;}} 

I added the authority Android.permission.SEND_SMS also put other related text messages and MMS permissions are added, but log inside prompted permission denied, because my virtual machine has a problem my test using the real machine. I am very short of knowledge in Android, but also ask the gods to see what is the line?

============ Solution 1============

Sms.sendtextmessage (This is the address of the recipient, NULL, MSG, send, NULL); You try this. The second parameter is the SMS Service center phone, and you wrote it wrong. should be null

============ Solution 2============

You debug to see what happens when it executes Logcat, the second parameter is the service center,

============ Solution 3============

Your phone is not loaded with 360 of such management software, so you blocked the action of short message
