How to set my sms app default in Android Kitkat?

I made an android sms app in which I am sending and receiving sms as android messaging app does so. Now I have set my target to 4.4 (Android KitKat version) but Android KitKat has new "Default Messaging" app settings that user can select one app at a time for messaging. I followed the steps from this site to select option for my sms app as default app but in the settings my app never showed up in the popup of selecting default messaging app.

Below is my java code I have used from the guid

if( androidOS.contains("4.4") ){


if (! Telephony.Sms.getDefaultSmsPackage(this).equals(myPackageName) ) {

// App is not default.
// Show the "not currently set as the default SMS app" interface

builder = new AlertDialog.Builder(MyConversation.this);
builder.setMessage("Shoot The Messenger is not set as your default messaging app. Do you want to set it default?")
.setCancelable(false)
.setTitle("Alert!")
.setNegativeButton("No", new DialogInterface.OnClickListener() {

@Override
public void onClick(DialogInterface dialog, int which) {


}
})
.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
@TargetApi(19)
public void onClick(DialogInterface dialog, int id) {

Intent intent =
new Intent(Telephony.Sms.Intents.ACTION_CHANGE_DEFAULT);

intent.putExtra(Telephony.Sms.Intents.EXTRA_PACKAGE_NAME,
getPackageName());

startActivity(intent);

}
});
builder.show();


}


}

Also I added below code in Manifest file.

UPDATE:

Note: I am testing on Emulator... After following all steps I only see the default messaging app of Android not mine like in the image given below. Any type of help will be appreciated. Thanks in Advance.

The instructions you posted were correct - the issue is that you must implement all of the required capabilities:

• In a broadcast receiver, include an intent filter for SMS_DELIVER_ACTION ("android.provider.Telephony.SMS_DELIVER"). The broadcast receiver must also require the BROADCAST_SMS permission. This allows your app to directly receive incoming SMS messages.

• In a broadcast receiver, include an intent filter for WAP_PUSH_DELIVER_ACTION ("android.provider.Telephony.WAP_PUSH_DELIVER") with the MIME type "application/vnd.wap.mms-message". The broadcast receiver must also require the BROADCAST_WAP_PUSH permission. This allows your app to directly receive incoming MMS messages.

• In your activity that delivers new messages, include an intent filter for ACTION_SENDTO ("android.intent.action.SENDTO") with schemas, sms:, smsto:, mms:, and mmsto:. This allows your app to receive intents from other apps that want to deliver a message.

• In a service, include an intent filter for ACTION_RESPONSE_VIA_MESSAGE ("android.intent.action.RESPOND_VIA_MESSAGE") with schemas, sms:, smsto:, mms:, and mmsto:. This service must also require the SEND_RESPOND_VIA_MESSAGE permission.

Without all four, your app will not be listed in the default SMS selection dialog.
