How to query the last sent SMS from content provider?

When I send an SMS on my Android emulator, it goes to the content provider:

content://sms/sent

right?

So I wanted to get the last sent SMS from the content provider. So I used this Uri as you can see above and I used the method query, with the Content Resolver Object. And I got the cursor, and used the movetofirst() method, so I would have the last sent SMS. Check the code below.

package com.sys;

import android.app.Activity;  
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.net.Uri;
import android.database.Cursor;

    public class SMS extends Activity {

Button btnVerSms;
EditText txtFinal;

final Uri CONTENT_URI = Uri.parse("content://sms/sent");    
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundl开发者_StackOverflow社区e savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    btnVerSms= (Button)findViewById(R.id.btnVerSms);
    txtFinal =   (EditText)findViewById(R.id.txtFinal);   

    btnVerSms.setOnClickListener(new View.OnClickListener() {

    @Override
    public void onClick(View v) {
        // TODO Auto-generated method stub
        Cursor cursor = getContentResolver().query(CONTENT_URI, null, null, null,  null);                                   
        String body = null;    

        if(cursor.moveToFirst()){
            body = cursor.getString(cursor.getColumnIndexOrThrow("body")).toString();               
        }
        txtFinal.setText(body);
    }
});
}
}

Hello, when I send an SMS on my Android emulator, it goes to the content provider: content://sms/sent right?

Not necessarily. You assume that content provider exists on all devices and is used by all SMS client applications. Those are not valid assumptions.

So I wanted to get the last sent SMS from the content provider.

That content provider is not part of the Android SDK.
