Sending SMS with Sending and delivery Notification

Working on SMS in Android is little bit logical, if you want sending and delivery notification. While working on SMS API’s in Android we have to pass five arguments as we have already discussed. Lets see how we do that.. Codes are same in main.xml and manifest file. I’m not going to change anything, only you have to add chunk of code in MainActivity.java so be happy Yipee 🙂

Source code :

Layout Designing: create a xml file named main.xml and add two TextView and two EditText and one Button.

main.xml

<?xml version=”1.0″ encoding=”utf-8″?>
<LinearLayout xmlns:android=”http://schemas.android.com/apk/res/android&#8221;
android:orientation=”vertical”
android:layout_width=”fill_parent”
android:layout_height=”fill_parent”
>
<TextView
android:layout_width=”fill_parent”
android:layout_height=”wrap_content”
android:text=”Enter the phone number of recipient”
/>
<EditText
android:id=”@+id/txtPhoneNo”
android:layout_width=”fill_parent”
android:layout_height=”wrap_content”
/>
<TextView
android:layout_width=”fill_parent”
android:layout_height=”wrap_content”
android:text=”Message”
/>
<EditText
android:id=”@+id/txtMessage”
android:layout_width=”fill_parent”
android:layout_height=”150px”
android:gravity=”top”
/>
<Button
android:id=”@+id/btnSendSMS”
android:layout_width=”fill_parent”
android:layout_height=”wrap_content”
android:text=”Send SMS”
/>
</LinearLayout>

mainifest.xml

<?xml version=”1.0″ encoding=”utf-8″?>
<manifest xmlns:android=”http://schemas.android.com/apk/res/android&#8221;
package=”com.example.sms”
android:versionCode=”1″
android:versionName=”1.0″ >
<uses-sdk android:minSdkVersion=”15″ />
<uses-permission android:name=”android.permission.SEND_SMS”/>
<uses-permission android:name=”android.permission.RECEIVE_SMS”/>
<application
android:icon=”@drawable/ic_launcher”
android:label=”@string/app_name” >
<activity android:name=”.SMSActivity” 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>

// —sends an SMS message to another device—

// —when the SMS has been sent i.e for Sending Intent—

sms.sendTextMessage(phoneNumber, null, message, sentPI, deliveredPI);
