Sending SMS programmatically without opening message app

So far I am using the following code to send SMS to another phone through my app.

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

However, this opens up the native messaging app, thereby putting my app's activity in the background. Is it possible to send the SMS directly without the native messaging app opening up? If yes, how?

You can send messages from your application through this:

public void sendSMS(String phoneNo, String msg) {
    try {      
        SmsManager smsManager = SmsManager.getDefault();
        smsManager.sendTextMessage(phoneNo, null, msg, null, null);    
        Toast.makeText(getApplicationContext(), "Message Sent",
                Toast.LENGTH_LONG).show();
    } catch (Exception ex) {
        Toast.makeText(getApplicationContext(),ex.getMessage().toString(),
                Toast.LENGTH_LONG).show();
        ex.printStackTrace();
    } 
}

Also, you need to give SEND_SMS permission in AndroidManifest.xml to send a message

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

public void sendLongSMS() {
    String phoneNumber = "0123456789";
    String message = "Hello World! Now we are going to demonstrate " + 
        "how to send a message with more than 160 characters from your Android application.";
    SmsManager smsManager = SmsManager.getDefault();
    ArrayList<String> parts = smsManager.divideMessage(message); 
    smsManager.sendMultipartTextMessage(phoneNumber, null, parts, null, null);
}

and don't forget to add

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