Question

I am creating a free version of android widget, and i want to display ads in it. But when we add Google Adsense in xml like

   <com.google.ads.GoogleAdView
    android:id="@+id/adview"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />

it shows following error. (I added the jar files also)

Anybody suggest that is it possible to display ads in android widget in anyother ways. Thanks in advance.

Answer 1

Widgets use RemoteViews to display their screen. RemoteViews typically require that all the display classes be available WITHOUT your entire APK having been loaded. http://developer.android.com/guide/topics/appwidgets/index.html#CreatingLayout shows you what View classes you can use: you currently can not use any custom views, therefore there is no way right now to use a com.google.ads.GoogleAdView in a widget.
