Admob ads loading but not showing

So in my LIBGDX game I'm trying to impement Admob ads.
They load fine but just wont show, even after a 60 second refresh or pressing home button and entering the game again.
I followed some answers on this site, but none of them helped.
Here's the code of Android Launcher class:
public class AndroidLauncher extends AndroidApplication implements AdHander{
private static final String TAG = "AndroidLauncher";
protected AdView adView;
private final int SHOW_ADS = 1;
private final int HIDE_ADS = 0;
Handler handler = new Handler(){
#Override
public void handleMessage(Message msg) {
switch (msg.what){
case SHOW_ADS:
adView.setVisibility(View.VISIBLE);
break;
case HIDE_ADS:
adView.setVisibility(View.GONE);
break;
}
}
};
#Override
protected void onCreate (Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
RelativeLayout layout = new RelativeLayout(this);
AndroidApplicationConfiguration config = new AndroidApplicationConfiguration();
View gameView = initializeForView(new Main(this), config);
adView = new AdView(this);
adView.setAdSize(AdSize.SMART_BANNER);
// HERE I IMPLEMENTED ADMOB TEST ID FOR BANNERS
adView.setAdUnitId("ca-app-pub-3940256099942544/6300978111");
adView.setBackgroundColor(Color.BLACK);
adView.setAdListener(new AdListener() {
#Override
public void onAdLoaded() {
int visibility = adView.getVisibility();
adView.setVisibility(AdView.GONE);
adView.setVisibility(visibility);
Log.i(TAG, "Ad loaded");
}
});
AdRequest.Builder builder = new AdRequest.Builder();
adView.loadAd(builder.build());
layout.addView(gameView);
RelativeLayout.LayoutParams adParams = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
adParams.addRule(RelativeLayout.ALIGN_PARENT_TOP);
adParams.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
layout.addView(adView, adParams);
setContentView(layout);
config.useImmersiveMode = true;
initialize(new Main(this), config);
}
#Override
public void showAds(boolean show) {
handler.sendEmptyMessage(show ? SHOW_ADS : HIDE_ADS);
}
}
What have I did wrong?

Check your manifest it should look similar to this one :-

I think you did not added all permission required, Please check below image

I know that the answer is very late. But I was looking for a solution to the same problem. And maybe it will help someone.
Map Service is an Android service that facilitates the use of a shared disk cache among applications that use the HERE SDK. This service must be embedded and deployed with your HERE-enabled application; otherwise, the MISSING_SERVICE error code is returned via the onEngineInitializationCompleted() callback.
To embed Map Service, add the following lines inside the <application> </application> section in your
AndroidManifest.xml file:
<service
android:name="com.here.android.mpa.service.MapService"
android:label="HereMapService"
android:process="global.Here.Map.Service.v2"
android:exported="true" >
<intent-filter>
<action android:name="com.here.android.mpa.service.MapService" >
</action>
</intent-filter>

Even if i exit the game, in the logcat i see that admob is still working.

Create an onStop() method and stop adMob there as well.

Try setting the AdView instance to NULL and leave it there for the GC to handle it. It probably will trow a NullPointerException so make sure you handle that.

I solved the problem.
I had two times Adview adview;
public class AndroidLauncher extends AndroidApplication {
private AdView adView;
#Override
protected void onCreate (Bundle savedInstanceState) {
***
// Create and setup the AdMob view
AdView adView = new AdView(this);
***
When I removed one, AdMob is working correctly.

Can't access google servers through android app

I'm developing a android app cappable of acessing the maps API, but i'm stuck on error:
Google Maps Android API﹕ Failed to load map. Error contacting Google
servers. This is probably an authentication issue (but could be due to
network errors).
Already did the key and activate everithing in google API console.
These are my files:

setContentView(R.layout.mapa_layout);
FragmentManager manager = getSupportFragmentManager();
FragmentTransaction transaction = manager.beginTransaction();
transaction.replace(R.id.mapa, new MapaFragment());
transaction.commit();
}
}
Any Idea?
Thanks for the help

I have done the same.
Try this in your MostraAlunosProximos class oncreate,
int status = GooglePlayServicesUtil
.isGooglePlayServicesAvailable(getBaseContext());
// Showing status
if (status != ConnectionResult.SUCCESS) { // Google Play Services
// are
// not available
int requestCode = 10;
Dialog dialog = GooglePlayServicesUtil.getErrorDialog(status,
this, requestCode);
dialog.show();
} else { // Google Play Services are available
SupportMapFragment fm = (SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.mapa);
// Getting GoogleMap object from the fragment
if (fm != null) {
googleMap = fm.getMap();
}
// Enabling MyLocation Layer of Google Map
googleMap.setMyLocationEnabled(true);
}
And add this line android:name="com.google.android.gms.maps.SupportMapFragment" inside fragment of your xml file.
And also i see there are two metadeta for google play service remove that.
Hope this helps

I did this and got to work on my device. Try it.

Try changing:

AdRequest adRequest = new AdRequest.Builder().build();
adView.loadAd(adRequest);
To:
AdView adView = (AdView)this.findViewById(R.id.adView);
adView.loadAd(new AdRequest());
