Answer 1

You can delete all SMS of a particular number by using,

private void removeMessage(Context context, String fromAddress) {

    Uri uriSMS = Uri.parse("content://sms/inbox");
    Cursor cursor = context.getContentResolver().query(uriSMS, null, 
                                                               null, null, null);
    cursor.moveToFirst();
      if(cursor.getCount() > 0){
        int ThreadId = cursor.getInt(1);
        Log.d("Thread Id", ThreadId+" id - "+cursor.getInt(0));
        Log.d("contact number", cursor.getString(2));
        Log.d("column name", cursor.getColumnName(2));

        context.getContentResolver().delete(Uri.
                parse("content://sms/conversations/"+ThreadId), "address=?", 
                                                      new String[]{fromAddress});
        Log.d("Message Thread Deleted", fromAddress);
      }
      cursor.close();
}
