class file :

madview = (adview) findviewbyid(r.id.adview);         adrequest = new adrequest.builder()                 .build();  madview.setadlistener(new adlistener() {             @override             public void onadclosed() {                 log.i("ads", "onadclosed");                 super.onadclosed();             }      @override     public void onadfailedtoload(int i) {         log.i("ads", "onadfailedtoload");         super.onadfailedtoload(i);     }      @override     public void onadleftapplication() {         log.i("ads", "onadleftapplication");         super.onadleftapplication();     }      @override     public void onadopened() {         log.i("ads", "onadopened");         super.onadopened();         adclosebutton.setvisibility(view.visible);     }      @override     public void onadloaded() {         log.i("ads", "onadloaded");         super.onadloaded();         adclosebutton.setvisibility(view.visible);     }  });   private void showbannerad() {      madview.loadad(adrequest);  } 

// destroy ad while click on close icon

 adclosebutton.setonclicklistener(new view.onclicklistener() {                 @override                 public void onclick(view v) {                     if(madview != null){                         madview.destroy();                     }                     adclosebutton.setvisibility(view.gone);                 }             }); 

from docs destroy

destroy ad view. method should called in parent activity's ondestroy() method. no other methods should called on ad view after destroy() called.

instead of calling destroy set visibility of adview view.invisible or view.gone. in onadloaded of adview make adview visible.
