`Caused by: java.lang.ClassNotFoundException: Didn't find class "com.google.android.gms.maps.MapFragment" on path: /data/app/com.example.maptest-2.apk` -- make sure you set up the Play Services SDK library project properly in your app. For example, if you manually modified the build path of your project, you did it wrong. — CommonsWare, Oct 01 '14 at 17:17

Make sure you have declared the fragment in your layout. Like following.

<fragment
          android:id="@+id/map"
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          android:name="com.google.android.gms.maps.MapFragment"/>

Also that you have added Google Play services library in your project.

Follow these instruction step by step : https://developers.google.com/maps/documentation/android/start

I had the same problem and I did the mistake to only add one of the 2 following tags. Note that you are also missing one of these two

        <meta-data
            android:name="com.google.android.geo.API_KEY"
            android:value="<YOUR VALUE>"/>
        <meta-data
            android:name="com.google.android.gms.version"
            android:value="@integer/google_play_services_version" />

The actual error is really misleading, as you might be thinking of some API level UI issue.
