Android – Sending SMS from android application – Method 2

By -

Hi,

Here i am going to discuss about to send SMS from your android application.

Basically there are 2 ways by which we can send sms:

  1. Open native SMS composer
  2. write your message and send from your android application

So here i am going to write about the 2nd method i.e. write your message and send from your android application itself.

(For your information, Method 1 – Send SMS by opening native SMS Composer)

Main.xml
<?xml version="1.0" encoding="utf-8"?>
<ScrollView
	android:id="@+id/scrollview1"
	android:layout_height="fill_parent"
	android:layout_width="fill_parent"
	xmlns:android="http://schemas.android.com/apk/res/android">
	<RelativeLayout android:id="@+id/relativeLayout1" android:layout_width="fill_parent" android:layout_height="fill_parent">
        <TextView
        	android:layout_width="wrap_content"
        	android:text="Enter mobile number:"
        	android:id="@+id/textView1"
        	android:layout_alignParentLeft="true"
        	android:layout_height="wrap_content">
        </TextView>
        <EditText
        	android:id="@+id/etextMblNumber"
        	android:layout_width="fill_parent"
        	android:layout_height="wrap_content"
        	android:layout_below="@+id/textView1"
        	android:inputType="number">
        </EditText>
         <TextView
        	android:layout_width="wrap_content"
        	android:text="Enter message:"
        	android:id="@+id/textView2"
        	android:layout_height="wrap_content"
        	android:layout_below="@+id/etextMblNumber">
        </TextView>
        <EditText
        	android:id="@+id/etextMsg"
        	android:layout_width="fill_parent"
        	android:layout_height="250dip"
			android:layout_below="@+id/textView2"
			android:gravity="top">
        </EditText>
        <Button
        	android:id="@+id/btnSendSMS"
        	android:layout_height="wrap_content"
        	android:layout_width="wrap_content"
        	android:text="Send SMS"
        	android:layout_below="@+id/etextMsg"
        	android:layout_centerInParent="true">
        </Button>
	</RelativeLayout>
</ScrollView>

SendSMSActivity

package com.technotalkative.sendsms;

import android.app.Activity;
import android.os.Bundle;
import android.telephony.SmsManager;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
public class SendSMSActivity extends Activity {
    /** Called when the activity is first created. */
	EditText eTextMsg, eTextMblNumber;
	Button btnSendSMS;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        eTextMblNumber = (EditText) findViewById(R.id.etextMblNumber);
        eTextMsg = (EditText) findViewById(R.id.etextMsg);
        btnSendSMS = (Button) findViewById(R.id.btnSendSMS);
        btnSendSMS.setOnClickListener(new OnClickListener()
        {
			public void onClick(View v) {
				// TODO Auto-generated method stub
				sendSMS();
			}
        });
    }
    public void sendSMS()
    {
    	SmsManager sm = SmsManager.getDefault();
		String number = eTextMblNumber.getText().toString();
		String msg = eTextMsg.getText().toString();
		sm.sendTextMessage(number, null, msg, null, null);
    }
}

Now, The main thing which we should not forget to add is the SEND_SMS permission inside the AndroidManifest.xml file:

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