AdMob banner ad not showing

Question

I am using admob in my app, it was working fine but suddenly it stopped showing ads at all. Bellow is my codes i used:

mainActivity.xml:

<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="@string/banner_ad_unit_id">
    </com.google.android.gms.ads.AdView>

MainActivity.java

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

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

        mAdView.loadAd(adRequest);

AndroidManifest:

 <uses-sdk
        android:minSdkVersion="9"
        android:targetSdkVersion="19" />

 <uses-permission android:name="android.permission.INTERNET"/>
        <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

<meta-data android:name="com.google.android.gms.version"
            android:value="@integer/google_play_services_version" />  

<!--Include the AdActivity configChanges and theme. -->
<activity android:name="com.google.android.gms.ads.AdActivity"
            android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"
            android:theme="@android:style/Theme.Translucent" />

I followed all the instructions from adMob site as i said it was working few days ago.

Bellow are few line from logcat which may be related to my issue:

09-25 22:44:50.292: E/dalvikvm(18554): Could not find class 'android.app.AppOpsManager', referenced from method com.google.android.gms.common.GooglePlayServicesUtil.zza

I get bellow warning repeatedly and it appears more when i click the blank area where ad should be showing

09-25 22:46:10.911: W/PicturePileLayerContent(18554): Warning: painting PicturePile without content!

I have searched everywhere for the solution and also looked at some similar but non of them helped me.

Answer 1

Check if you have latest versions of adMob and GooglePlayServices lib.

Answer 2

Put the banner in a LinearLayout just as this ,i faced the same problem and i fixed it by puting it in a linear layout

  <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:ads="http://schemas.android.com/apk/res-auto"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    android:layout_alignParentTop="true"
    android:layout_alignParentRight="true"
    android:layout_alignParentEnd="true"
    android:id="@+id/linearLayout">

    <com.google.android.gms.ads.AdView
        android:id="@+id/adView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        ads:adSize="BANNER"
        ads:adUnitId="ca-app-pub-8056472942589154/2652831823"
        android:layout_alignBottom="@+id/saida"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true" />
</LinearLayout>

Answer 3

In my case the ad didnt show up until I gave enough room for it.

Before it was like

<LinearLayout
        android:orientation="vertical"
        android:background="@color/primary"
        android:layout_width="match_parent"
        android:layout_height="90dip">
           <ImageView
                android:onClick="goBack"
                android:clickable="true"
                android:src="@drawable/ic_arrow_back_white_48dp"
                android:layout_width="50dip"
                android:layout_height="50dip"/>
           <com.google.android.gms.ads.AdView
                android:layout_gravity="center_horizontal"
                android:id="@+id/adView"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                ads:adSize="BANNER"
                ads:adUnitId="@string/dwn_bnr_ad"/>

Here the adview is having height of wrap_content, so it adjusts itself to achieve its height, but its parent (LinearLayout) has a strict height of 90dip which doesnt allow the adView to take enough space to display ads.

So what I did was just changed the height of the LinearLayout to wrap_content then things got fine

Answer 4

Make sure that you have added Banner Ad Unit in your Admob Account and used banner appUnit-id in your adUnitId of your app where Banner Ads are displayed .

Answer 5

Use below lines of code

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

AdRequest request = new AdRequest.Builder()
.addTestDevice(AdRequest.DEVICE_ID_EMULATOR)        // All emulators
.addTestDevice("AC98C820A50B4AD8A2106EDE96FB87D4")  // My Galaxy Nexus test phone
.build();


mAdView.loadAd(request );

instead of using this

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

because this line will be used when your application would be ready for publish on Google Play Store.

You can place your device's id in place of "AC98C820A50B4AD8A2106EDE96FB87D4". Code to get device id:

String android_id = Settings.Secure.getString(getContext().getContentResolver(),
            Settings.Secure.ANDROID_ID);

Please read these carefully:

Answer 6

Did you go back to your admob account to register your specific app for ads and get a new longer publisher number with the 'ca-app-pub-' preface instead of the 'pub-' preface?

Nowhere in the "banner ads 1" instructions on the Google Admob "Google Mobile Ads SDK" development site does it mention having to go back to your admob account to do this.

This stupid mistake held me up for days.
