AdMob not work on real device

Question

I've used this guide for display an AdMob Banner in my app https://firebase.google.com/docs/admob/android/quick-start My problem is that the AdMob banner is only shown on my test device like this But on real device I don't see anything My dependencies in gradle file is:

dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')

compile 'com.android.support:appcompat-v7:25.1.0'
compile 'com.android.support:design:25.1.0'
compile 'de.hdodenhof:circleimageview:1.3.0'
compile 'com.android.support:support-v4:25.1.0'

compile 'com.google.firebase:firebase-core:10.0.1'
compile 'com.google.firebase:firebase-ads:10.0.1'

compile 'com.google.android.gms:play-services:10.0.1'

compile 'com.android.support:multidex:1.0.1'
testCompile 'junit:junit:4.12'
}
apply plugin: 'com.google.gms.google-services'

This is my code:

MobileAds.initialize(getContext(), "ca-app-pub-****");
AdRequest request = new AdRequest.Builder()
            .addTestDevice(AdRequest.DEVICE_ID_EMULATOR)
            .addTestDevice("4F8D70E24813A8C1CFF9B07A47A4F484")
            .setRequestAgent("android_studio:ad_template")
            .build();
    mAdView.loadAd(request);

And this is my xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:ads="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.saffru.colombo.navigationdrawervideotutorial.MainFragment">

<!-- TODO: Update blank fragment layout -->

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textAppearance="?android:attr/textAppearanceLarge"
    android:text="@string/l_apos_onomastico_di_oggi"
    android:id="@+id/textView2"
    android:layout_alignParentTop="true"
    android:layout_centerHorizontal="true"
    android:layout_marginTop="100dp" />

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textAppearance="?android:attr/textAppearanceLarge"
    android:text="@string/xxx"
    android:id="@+id/textView3"
    android:textColor="@color/verde1"
    android:layout_below="@+id/textView2"
    android:layout_centerHorizontal="true"
    android:layout_marginTop="46dp" />

<com.google.android.gms.ads.AdView
    android:id="@+id/adView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"
    android:layout_alignParentBottom="true"
    ads:adSize="BANNER"
    ads:adUnitId="ca-app-pub-****">
</com.google.android.gms.ads.AdView>


</RelativeLayout>

It doesn't work.

This is a screenshot of my app.

My code is

MobileAds.initialize(getContext(), "ca-app-pub-6864438797370510/3840785983");

AdView mAdView = (AdView) view.findViewById(R.id.adView);
AdRequest adRequest = new AdRequest.Builder().build();
mAdView.loadAd(adRequest);

And in my AdMob account I see this

If I add .addTestDevice("***") My logcat is

This code for testing the admob ads. I think, You followed the test ads tutorial.

You need to create you own app in the admob account and include your ad-unit in initialize part.

The reference link : https://support.google.com/admob/answer/3052638

Your activity code.

            MobileAds.initialize(getApplicationContext(), "Your own admob ad-unit");

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

These four line is enough. Other than this everything is fine.

Note: Don't test your real admob ad-unit. If so, There is chance to terminate your admob account by google.

You need to use your real ad-unit when you release app in play store.
