Admob xml: the following classes could not be instantiated: - com.google.android.gms.ads.AdView

I followed all the steps to import google-play-services, tried re-installing sdk, re-importing. I tried adding weight and text-views to give it space... I tried everything for the past 2 days, but keep getting this error on the graphical interface of the xml layout saying: 

the following classes could not be instantiated: - com.google.android.gms.ads.AdView.

This worked for me:

Open your xml layout, Switch to Text view, On the Preview pane click the Refresh button and the problem will be solved.

If the problem persists, make sure you have the firebase ads dependency in your app's build.gradle file:

compile 'com.google.firebase:firebase-ads:9.8.0'

This is a temporary work-around for me. I downgraded the version of Google Play Services SDK from 5.x back to 4.x. I use Intellij Community 13.x with Gradle so my dependency section looks like this now:

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:support-v4:20.0.0'
    compile 'com.android.support:appcompat-v7:20.0.0'
    compile 'com.google.android.gms:play-services:4.+'
}

Again, just temporary to allow me to finish building my XML layout files. I plan to upgrade to the latest version 5.x when I enter my final testing phase. I have filed issues about this problem with the Google AdMob Ads Developers forum in hopes of getting someone's attention. Not exactly sure where to file a bug report for this specific SDK. .

Declare com.google.android.gms.ads.AdActivity in the manifest,i.e. in your manifest file change

 <activity android:name="com.google.android.gms.ads.AdView"
               android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"/>

to

 <activity android:name="com.google.android.gms.ads.AdActivity"
                  android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"/>

For more info see Declare com.google.android.gms.ads.AdActivity

Also add android:id="@+id/adView" in your xml view as

 <com.google.android.gms.ads.AdView
        android:id="@+id/adView"
        android:layout_width="320dp"
        android:layout_height="50dp"
        android:layout_alignParentBottom="true"
        android:layout_centerHorizontal="true"
        ads:adSize="BANNER"
        ads:adUnitId="ca-app-pub-1278770925901425/7987430192"
        ads:loadAdOnCreate="true"
        android:gravity="center" >
    </com.google.android.gms.ads.AdView>

And don't forget to clear project.

This is because you have added wrong activity class in your manifest file. So just change it with this.

<activity android:name="com.google.android.gms.ads.AdActivity"
              android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"/>
