02-04 15:12:53.879: I/Ads(24771): Use AdRequest.Builder.addTestDevice("E31172B18E054F6A03B7BD138EA6B376") to get test ads on this device.

02-04 15:12:56.699: W/Ads(24771): There was a problem getting an ad response. ErrorCode: 0 02-04 15:12:56.729: W/Ads(24771): Failed to load ad: 0

Answer 1

Just wait for a few hours and you'll start getting the ads. If it is a newly created ad unit id it will take some time for the servers to replicate it on all instances (also called warming up of ad unit).

If it worked with test device id added it will work fine without the test device ids.
