setcontentview(r.layout.activity_main);          adview adview = (adview)this.findviewbyid(r.id.adview);          adrequest adrequest = new adrequest.builder()         .addtestdevice(adrequest.device_id_emulator)       //          .addtestdevice("3a2d1115ab64e3") //           .build() ;         adview.loadad(adrequest); 

the ad xml namespace wrong:

in googleadmobadssdk-6.4.1.jar or earlier use:

<com.google.ads.adview  

with namespace:

 xmlns:ads= "http://schemas.android.com/apk/lib/com.google.ads" 

in google admob via play service library, use:

<com.google.android.gms.ads.adview 

with namespace:

 xmlns:ads="http://schemas.android.com/apk/res-auto
