google admob access

When introduced into the jar prior access admob

implementation 'com.google.android.gms:play-services-ads:17.2.0'
implementation 'com.google.firebase:firebase-core:+'
implementation 'com.google.firebase:firebase-messaging:+'

I have access only when referring to admob, found no ads, look at the last road firbase also need to reference, because admob and are used in combination, too. (I may not have to use to find the right method),

Then in the manifest file

<meta-data android:name="com.google.android.gms.ads.APPLICATION_ID" android:value=""/>

Add a reference appid, you need to add, no error will be added

Then access is to begin advertising. You can use the access they have to have time to test id, was the last direct use of online advertising is not returned

This is the complete code.

Was in use, remember to initialize ad

 

MobileAds.initialize(this, "");
