Not enough space to show ad with ViewPager

[FiltrSoft]

Has anyone successfully integrated AdMob into an Android app with a ViewPager?  I'm getting an issue where they are not showing or they show, but sporadically.  I think it has something to do with how ViewPagers cache the views, but I'm not entirely sure.

I have a SO post that details it more:

Hey FiltrSoft,

We have an example on including ads within a Tabbed View in our Ad Catalog project. It doesn't use a VIewPager, but was based off of the Android ViewPager example. This example puts the ad outside of the TabHost (as you can see from the XML file) so you don't have to worry about changing the ad state when the tab changes.

Thanks,
Eric

From your SO post, it looks like you're actually using a ListView. The Ad Catalog has an example for that too, which includes a List Adapter wrapper that adds an ad at the top and bottom of your ListView.

Thanks,

Eric, thanks for the response. Setting the ad via XML, as opposed to programmatically, seemed to get the ads working.

One other thing, have you seen this issue before?  If there is an ad showing on one of the pages of the ViewPager and I swipe on the ad itself, my app is crashing with a NullPointerException coming from the ad itself.  Something to do with "canScrollHorizontally"?  A Google search of "canScrollHorizontally" didn't seem to return many results.

I ended up reverting to the older AdMob JAR, which didn't seem to have this issue.

[Eric Leichtenschlag]

It looks like this crash was introduced with v6.3.0. v6.2.1 shouldn't have the issue, and it'll be fixed for the next release.

Thanks,
Eric
