Show compose SMS view in Android

Question

You can use the following code:

startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("sms:"
                        + phoneNumber)));

Make sure you set phoneNumber to the phone number that you want to send the message to

You can add a message to the SMS with (from comments):

Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("sms:" + phoneNumber));     
intent.putExtra("sms_body", message); 
startActivity(intent);

This worked for me.

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    Button btnSendSMS = (Button) findViewById(R.id.btnSendSMS);
    btnSendSMS.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            sendSMS("5556", "Hi You got a message!");
           /*here i can send message to emulator 5556. In Real device 
            *you can change number*/
        }
    });
}

//Sends an SMS message to another device

private void sendSMS(String phoneNumber, String message) {
    SmsManager sms = SmsManager.getDefault();
    sms.sendTextMessage(phoneNumber, null, message, null, null);
}

You can add this line in AndroidManifest.xml

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

Take a look at this

This may be helpful for you.

Try the below code and then call, sendSMS("99999999999", "message"); to send sms in desired number.

//---sends an SMS message to another device---
@SuppressWarnings("deprecation")
private void sendSMS(String phoneNumber, String message)
{        
    Log.v("phoneNumber",phoneNumber);
    Log.v("MEssage",message);
    PendingIntent pi = PendingIntent.getActivity(this, 0,
    new Intent(this, **DummyClasshere.class**), 0);                
    SmsManager sms = SmsManager.getDefault();
    sms.sendTextMessage(phoneNumber, null, message, pi, null);        
}

Please place the following permission into AndroidManifest.xml file.

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

Hope this might help.

Update From the comment: DummyClasshere.class is an activity without doing any process or the class in which u need to navigate.

You can use Object.class in place of DummyClasshere.class.

This will definitely work, In this, Send message without using any intent .

SmsManager smsManager =     SmsManager.getDefault();
smsManager.sendTextMessage("Phone Number", null, "Message", null, null);

This code is used for send message in background (Not showing message composer), It can also work inside the Broadcast receiver. If you want to send a message from Broadcast receiver.

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