Programming for Android. Interception of incoming SMS

Question

Java

Hello, dear Habra community! I recently decided to try my hand at programming for Android. I am writing an application, the essence of which is that it intercepts all incoming messages and if any message satisfies certain conditions, then it is immediately deleted.

After intercepting the message, I have an instance of SmsMessage. I am trying to remove it like this:

Uri deleteUri = Uri.parse("content://sms");
context.getContentResolver().delete(
  deleteUri,
  "address=? and date=?",
  new String[] {sms.getOriginatingAddress(), String.valueOf(sms.getTimestampMillis())});

After performing these steps, the SMS message remains in the Inbox folder.

I decided to view my entire inbox like this:

Uri uriSms = Uri.parse("content://sms/inbox");
Cursor c = context.getContentResolver().query(uriSms, null,null,null,null);
while (c.moveToNext())
{
  String body = c.getString(c.getColumnIndex("body"));
  long data = c.getLong(c.getColumnIndex("date"));
  String address = c.getString(c.getColumnIndex("address"));
}
c.close();

It turns out that data and sms.getTimestampMillis() differ by about 200 milliseconds. That is, the where condition in the delete query is not met.

Maybe I'm doing something wrong? I ask for your help.

UPD : Maybe somehow it is possible to process incoming SMS before the system itself, so that the user does not even see the notification?
