Android Send SMS Tutorial

In this Android tutorial, I will walk you through to create an Android app to send SMS. It would be cool to have our own SMS application to send SMS messages.

There can be missing features in the SMS application that comes by default with our Android phone. We can use the example application here and build on top of it according to our needs.

Send-Android-SMS

Application is simple and easy to build. SmsManager class takes care of sending the SMS message. We just need to get an instance of it and send the SMS message. We need to add permission to SEND_SMS in the Android manifest file.

SMS Application

Download

Just note the permission added to send sms in the below manifest file.

AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.javapapers.androidsms">

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

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme">
        <activity
            android:name=".SendSmsActivity"
            android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>
</manifest>

activity_sms.xml

This layout file has the mobile number to send SMS and the SMS message to be sent.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/toPhoneNumberTV"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Phone Number" />

    <EditText
        android:id="@+id/toPhoneNumberET"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:inputType="phone"/>

    <TextView
        android:id="@+id/smsMessageTV"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="SMS Message" />

    <EditText
        android:id="@+id/smsMessageET"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:inputType="textMultiLine"/>

    <Button android:id="@+id/sendSMSBtn"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="Send SMS"/>

</LinearLayout>

SendSmsActivity.java

Here is the Android Activity class. Its just one thing, instantiate the SmsManager class and send SMS using it.

package com.javapapers.androidsms;

import android.app.Activity;
import android.os.Bundle;
import android.telephony.SmsManager;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;

public class SendSmsActivity extends Activity {

    Button sendSMSBtn;
    EditText toPhoneNumberET;
    EditText smsMessageET;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_sms);
        sendSMSBtn = (Button) findViewById(R.id.sendSMSBtn);
        toPhoneNumberET = (EditText) findViewById(R.id.toPhoneNumberET);
        smsMessageET = (EditText) findViewById(R.id.smsMessageET);
        sendSMSBtn.setOnClickListener(new View.OnClickListener() {
            public void onClick(View view) {
                sendSMS();
            }
        });
    }

    protected void sendSMS() {
        String toPhoneNumber = toPhoneNumberET.getText().toString();
        String smsMessage = smsMessageET.getText().toString();
        try {
            SmsManager smsManager = SmsManager.getDefault();
            smsManager.sendTextMessage(toPhoneNumber, null, smsMessage, null, null);
            Toast.makeText(getApplicationContext(), "SMS sent.",
                    Toast.LENGTH_LONG).show();
        } catch (Exception e) {
            Toast.makeText(getApplicationContext(),
                    "Sending SMS failed.",
                    Toast.LENGTH_LONG).show();
            e.printStackTrace();
        }
    }
}

    Dear Joe,

    I find your continuous contribution on the internet of a great value. Since last time I wrote to you, we have closed the college, as we are now concentrating on making software, and we are doing great.

    Now, how can we do something great for you? I have asked you before, and I would like if you can spend a little time thinking about how we can do something for you?

    Warmly

    Dear Joe,

    One thing, maybe… Try to click on paper.li, its an automated news paper, where you can link certain twitter accounts, Google+ accounts, facebook etc, and then it generates a news paper based on your chosen feeds.

    That way, you can indeed create new stuff, in that you make the paper partially get content from sources you respect, and then your own sources. Then that publishes to those who are interested.

    Its pretty hot, that paper – and free of charge.

    Warmly
    David

  7. Arnab says:

    Hi, I am making an application where i need to send sms at a particular time of the day. I had set up all the time picker activities and all. But I am confused if I just compare the current system time and the set time, and then use the sendSMS class, would it be sent? Also, does the system needs to be in a certain condition for this to work?

    Any help would be greatly appreciated.

    Thanks
