    if you look closely in the log you posted, on line 6 you will notice that googleads.g.doubleclick.net resolves to 127.0.0.1. This usually means that the hosts file on your phone was tampered, with the purpose of blocking ads in all your apps.

    If you’re running this on an emulator, either your emulator’s hosts file was tampered, or your computer’s OS hosts file. You should check those out.
