Display received messages in the default SMS app and the native messaging app

Question

I have created a messaging app that can be set as the default SMS app in KitKat (Android 4.4). This app listens for and catches specific messages, then raises an event after receiving them. The problem is that messages I don't need to catch are not appearing in the native messaging app's inbox. How can I display those messages in the native messaging app on the device while having my app as the default?

Answer 1

When your app is the default SMS app, it is responsible for writing incoming messages to the Provider, as it is the only app with write access to it. The following is a very simple, minimal example, and assumes you have the following import:

 import android.provider.Telephony.*;

And the example write method:

private void insertSms(String number, String message)
{
    ContentValues smsValues = new ContentValues();
    smsValues.put(Sms.ADDRESS, number);
    smsValues.put(Sms.BODY, message);
    smsValues.put(Sms.DATE, System.currentTimeMillis());

    context.getContentResolver().insert(Sms.Inbox.CONTENT_URI, smsValues);  
}
