MapView bloat issue

I am browsing the documentation in Hello MapView to add MapView to my activity.

When I start my activity, I get an inflation error on MapView.

Here is the MapView in my xml layout:

<com.google.android.maps.MapView
    android:id="@+id/mymap"
    android:layout_width="fill_parent"
    android:layout_height="200dip"
    android:clickable="true"
    android:apiKey="withheld"
    />

Here is the code in my MapActivity (the class is called ActivityDetails and extends the MapActivity class):

    MapView mMap;
    mMap = (MapView) findViewById(R.id.mymap);
    mMap.setBuiltInZoomControls(true);

Here is the error:

As far as I can tell, I did everything right, as described in the documentation. I set the build target for the Google APIs, I added the uses-library tag to my manifest, I run the emulator with the Google API target ...

The problem was calling super.onCreate () after setContentView () in MapActivity.

xml MapView

, MapActivity, setContentView() xml,

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
