Mengirim pesan SMS dengan android bisa dengan dua cara. Dengan menggunakan SmsManager API atau Aplikasi Built-in SMS pada device untuk mengirim pesan SMS. dalam kesempatan kali ini akan membahas dua cara pengiriman SMS tersebut.

1. SmsManager API

SmsManager smsManager = SmsManager.getDefault();
smsManager.sendTextMessage("0987654321", null, "isi pesan sms", null, null);

2. Built-in SMS application

Intent smsIntent = new Intent(Intent.ACTION_VIEW);
smsIntent.setData(Uri.parse("smsto:"));
smsIntent.setType("vnd.android-dir/mms-sms");
smsIntent.putExtra("address"  , new String ("0987654321"));
smsIntent.putExtra("sms_body"  , "isi pesan sms");
startActivity(smsIntent);

dari kedua metode diatas diperlukan user permision untuk mengirim sms pada file AndroidManifest.xml

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

1. Contoh penggunaan SmsManager

Buat project baru, pada file layout Activity_main.xml

<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/textViewPhoneNo"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Enter Phone Number : "
        android:textAppearance="?android:attr/textAppearanceLarge" />

    <EditText
        android:id="@+id/editTextPhoneNo"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:phoneNumber="true" >
    </EditText>

    <TextView
        android:id="@+id/textViewSMS"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Enter SMS Message : "
        android:textAppearance="?android:attr/textAppearanceLarge" />

    <EditText
        android:id="@+id/editTextSMS"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:inputType="textMultiLine"
        android:lines="5"
        android:gravity="top" />

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

</LinearLayout>

Pada Activity, file MainActivity.java

package id.web.sinaryuda.android.tutorial.kirimpesansms;

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;
import android.widget.Toast;

public class MainActivity extends Activity {

	Button buttonSend;
	EditText textPhoneNo;
	EditText textSMS;

	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);

		buttonSend = (Button) findViewById(R.id.buttonSend);
		textPhoneNo = (EditText) findViewById(R.id.editTextPhoneNo);
		textSMS = (EditText) findViewById(R.id.editTextSMS);

		buttonSend.setOnClickListener(new OnClickListener() {

			@Override
			public void onClick(View v) {

			  String phoneNo = textPhoneNo.getText().toString();
			  String sms = textSMS.getText().toString();

			  try {
				SmsManager smsManager = SmsManager.getDefault();
				smsManager.sendTextMessage(phoneNo, null, sms, null, null);
				Toast.makeText(getApplicationContext(), "SMS Terkirim!",
							Toast.LENGTH_LONG).show();
			  } catch (Exception e) {
				Toast.makeText(getApplicationContext(),
					"SMS Gagal terkirim, cek pulsa dan coba lagi",
					Toast.LENGTH_LONG).show();
				e.printStackTrace();
			  }

			}
		});
	}
}

2. Contoh penggunaan aplikasi SMS Built-in.

Buat project baru, pada file layout Activity_main.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/linearLayout1"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

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

</LinearLayout>

Pada Activity, file MainActivity.java

package id.web.sinaryuda.android.tutorial.kirimpesansms;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.Toast;

public class MainActivity extends Activity {

	Button buttonSend;

	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);

		buttonSend = (Button) findViewById(R.id.buttonSend);

		buttonSend.setOnClickListener(new OnClickListener() {

			@Override
			public void onClick(View v) {

				try {
                                Intent smsIntent = new Intent(Intent.ACTION_VIEW);
				smsIntent.setData(Uri.parse("smsto:"));
				smsIntent.setType("vnd.android-dir/mms-sms");
				smsIntent.putExtra("address"  , new String ("0123456789") );
				smsIntent.putExtra("sms_body"  , "isi pesan sms");
				startActivity(smsIntent);

				} catch (Exception e) {
					Toast.makeText(getApplicationContext(),
						"Aplikasi SMS tidak ada",
						Toast.LENGTH_LONG).show();
					e.printStackTrace();
				}
			}
		});
	}
}

Pastikan pada file AndroidManifest.xml telah ditambahkan user permission SEND_SMS

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="id.web.sinaryuda.android.tutorial.kirimpesansms"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk android:minSdkVersion="8" />

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

    <application
        android:debuggable="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <activity
            android:label="@string/app_name"
            android:name=".MainActivity" >
            <intent-filter >
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>
