From the 25th of june two unrelated apps that are using ads started to have this NPE
java.lang.NullPointerException
at zo.a(SourceFile:172)

According to: https://groups.google.com/forum/#!topic/google-admob-ads-sdk/DkjtCx_Zvn8
Some have had a success by adding android:theme="@android:style/Theme.Translucent" to activity android:name="com.google.android.gms.ads.AdActivity" in the manifest.
I'm rolling out a new version with that fix now. Will see in a couple of days if it helps.
