How to add adMob Banner into getView using the latest SDK - com.google.android.gms.ads

Question

I'm trying to add adMob Banner ads into the getView method used for my ListView in one of my fragments. I'm using the latest adMob SDK (com.google.android.gms.ads.).

I'm only finding examples which use the older versions of the Google SDK. If anyone has a link to example of a current version of Google admob please let me know.

FYI - I took Tim's suggestion. I found a complete sample of code from http://jmsliu.com/1482/adding-admob-banner-in-android-listview-header.html.

Its a different one that I first showed you but is set up with 3 Activities. After several hours of testing I thought I would show you my code and the error I'm currently getting, and the original code. I added "Log.i" throughout the program to determine which line causes the abend. It appears that the ads is returning null. Also, note that the original version of code (after the error section) has special "keytwordSet" logic. I was unable to get rid of the syntax errors so I removed it from my version.

AdRequest adRequest = new AdRequest(); Set keywordsSet = new HashSet(); keywordsSet.add("game"); keywordsSet.add("dating"); keywordsSet.add("money"); keywordsSet.add("girl"); adRequest.addKeywords(keywordsSet); adView.loadAd(adRequest);

New Code:

• PostItemAdapter.java
• • Adapter Class which configs and returns the View for ListView

• */ package com.jms.admobinlistview;

Tim, thanks for getting back to me. The following is my code and error message that I'm getting. I tried several things and I keep getting the same type of errors. Can you please clarify your explanation you gave? Is purview really preview?

It looks like you are hiding the class variable 'adView' in the new code by declaring a local variable of the same name. Due to the scope, you're setting convertView to the global adView, which is always null. Just change "AdView adView =" to "adView ="
