</LinearLayout>

I added the google.service jar in this way: moved the folder: google-play-services_lib to the main app folder.

then, I entered eclipsed, and imported my app > right click on the app name > Properties > Android > on the Libery Clicked 'Add' > added the Google play service: http://i.stack.imgur.com/9dHrM.png

got the library in my project: http://i.stack.imgur.com/1gEq6.jpg

when I'm trying to run my app, this error appear::

(26935): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.manishma/com.manishma.MainActivity}: android.view.InflateException: Binary XML file line #287: Error inflating class com.google.ads.AdView

the unitID is checked (changed the code for the example).

what I'm doing wrong?

Answer 1

You are mixing the 2 ways possible right now to display Admob ads. The first one is based on the Android SDK, the second one is based on Google Play services.

The difference between the 2 implementations are explained in details in the developers documentation

In my opinion Google Play services is still too buggy to be used, but soon this will be the only option left.

In your case you mix both because you are using the XML declarations from the Android SDK but at the same time you are integrating the Google Play Services library. You cannot use both, you need to choose one and follow the developer guide I gave above.

Update

1) If you want to use Google Play services, change your XML with this:

<com.google.android.gms.ads.AdView
xmlns:ads="http://schemas.android.com/apk/res-auto"
android:id="@+id/adView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
ads:adUnitId="MY_AD_UNIT_ID"
ads:adSize="BANNER"/>

2) If you want to use the Android SDK, you have to add the GoogleAdMobAdsSdk jar in your libs folder and remove the Google Play services library.

Those are not the only things to do, manifest files must for example also be updated (see documentation).
