first, based on requirements, decide whether use native ads express or advanced described here. native ads express, may want read user guide here.

here sample on how load nativeexpressaddview:

public class mainactivity extends appcompatactivity {      private static string log_tag = "example";      nativeexpressadview madview;     videocontroller mvideocontroller;      @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_main);          // locate nativeexpressadview.         madview = (nativeexpressadview) findviewbyid(r.id.adview);          // set video options.         madview.setvideooptions(new videooptions.builder()                 .setstartmuted(true)                 .build());          // videocontroller can used lifecycle events , info ad's video         // asset. 1 returned getvideocontroller, if ad has no video         // asset.         mvideocontroller = madview.getvideocontroller();         mvideocontroller.setvideolifecyclecallbacks(new videocontroller.videolifecyclecallbacks() {             @override             public void onvideoend() {                 log.d(log_tag, "video playback finished.");                 super.onvideoend();             }         });          // set adlistener adview, activity can take action when ad has finished         // loading.         madview.setadlistener(new adlistener() {             @override             public void onadloaded() {                 if (mvideocontroller.hasvideocontent()) {                     log.d(log_tag, "received ad contains video asset.");                 } else {                     log.d(log_tag, "received ad not contain video asset.");                 }             }         });          madview.loadad(new adrequest.builder().build());     } }
