android - admob getting an ad response. ErrorCode: 0 Failed to load ad:0

Question

I have followed many answers about that error here, but my problem is not solved. Every time I run my app no ads appear and I get this error message in Logcat:

"There was a problem getting an ad response. ErrorCode: 0 Failed to load ad:0"

Here is my java code. What did I miss?

private void LoadAds() {

 AdView mAdView = (AdView) findViewById(R.id.linearLayoutAdmob);

 AdRequest adRequest = new AdRequest.Builder().build();

 mAdView.loadAd(adRequest);

and here my xml layout with admob at the last lines

I cannot figure what the problem is. I'm new in android development.

Answer 1

This is what google says

"It could be that you have only recently created a new Ad Unit ID and requesting for live ads. It could take a few hours for ads to start getting served if that is that case. If you are receiving test ads then your implementation is fine. Just wait a few hours and see if you are able to receive live ads then. If not, can send us your Ad Unit ID for us to look into."

so basically you have to wait for a few hours :)
