i calling above code in main activity , using upload images , video.

you pass view asynctask, create new constructor show/hide it, notice have runonuithread view.

private class uploadfiletoserver extends asynctask<void, integer, string> {     imageview iv_loading;     public uploadfiletoserver(imageview iv_loading){         this.iv_loading = iv_loading;     }      @override     protected void onpreexecute() {         super.onpreexecute();         runonuithread(new runnable() {                               @override                               public void run() {                                   iv_loading.setvisibility(view.visible);                               }                           }             );     }     ...     @override     protected void onpostexecute(string result) {         super.onpostexecute(result);         runonuithread(new runnable() {                               @override                               public void run() {                                   iv_loading.setvisibility(view.gone);                               }                           }             );      }    }
