Hi, Is the ad called from the main thread(UI thread). try Loading the view example : adView.loadAd() from the activity context and check. if you are on different thread try below code. activity.runOnUiThread(new Runnable() { @Override public void run() { ..... adView.loadAd(); } }); i hope this will solve.

Just look at the crash stack I included. THE PROBLEM IS IN AMAZON CODE. In fact, I am using XML to implement the advert!!!! See here: 11at android.view.ViewGroup.removeAllViews(ViewGroup.java:3681) 12at com.amazon.device.ads.MraidRenderer.boolean render()(SourceFile:86) 13at com.amazon.device.ads.AdController.void handleResponse()(SourceFile:439) 14at com.amazon.device.ads.AdLoader.void finalizeFetchAd()(SourceFile:273) 15at com.amazon.device.ads.AdLoader$AdFetcherTask.void onPostExecute(com.amazon.device.ads.AdLoader)(SourceFile:397) 16at com.amazon.device.ads.AdLoader$AdFetcherTask.void onPostExecute(java.lang.Object)(SourceFile:383) 17at android.os.AsyncTask.finish(AsyncTask.java:602) See ? YOU GUYS are the ones who have not used runOnUiThread on YOUR AsyncTask's onPostExecute..... Now, on most devices this is not a problem. But for a number of devices (including Samsung, LG, Droid), their Android OS does NOT force the AsyncTask's onPostExecute to run on the GUI thread. This is REALLY badly documented, so I am not surprised your dev team did not know it. Please fix (so I can send you 500k+ impressions per day which are mostly Kindle)....

Guys (Kevin probably), AsyncTask's onPostExecute() does NOT ALWAYS RUN ON THE GUI thread..... ESPECIALLY on pre-4.0 Android. Since you wanted code: public class Banner extends Advert_BaseClass implements AdListener { private AdLayout amazonAd; private String network; public Banner(Context context, AttributeSet attrs) { super(context, attrs); ... determine 'network' using sharedprefs LayoutInflater layoutInflater = (LayoutInflater)mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE); if (network.contentEquals("mopub") || network.length() == 0) { } else if (network.contentEquals("amazon")) { AdRegistration.setAppKey("asdf"); AdTargetingOptions options = new AdTargetingOptions(); options.enableGeoLocation(true); LinearLayout layout = (LinearLayout) layoutInflater.inflate(R.layout.ad_banner_amazon, null); amazonAd = (AdLayout) layout.findViewById(R.id.adview); LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT); addView(layout, params); amazonAd.loadAd(options); } else if ()...... And you probably need: public abstract class Advert_BaseClass extends LinearLayout { And the layout/ad_banner_amazon.xml layout is just an Amazon XML snippet with a LinearLayout around it. The custom view ie: Banner() is created as part of a larger XML sheet whose id is passed to setContentView. amazonAd.loadAd() therefore runs in the GUI thread.
