Thank you, man.
Well, I would try it again, please help me out.
My question is, if you want to block a message based on the sender's number,
probably you would code like this as I did,
cursor = context.getContentResolver().query(...., malicious_number, ...);
Uri mUri = Uri.parse("content://sms/" + cursor.getString(0));
context.getContentResolver().delete(mUri, null, null);
Those code works sometimes on the HTC Hero + Android 2.1, preventing the new
message showing in the Message app, but sometimes just doesn't. Even if it
works, the new message still trigger a notification and a ring sound. That
is not what we call blocking, isn't it?
So, is there any to target and block a message *silently*?
Thank you.
