Google map api v2 shows blank screen with only zoom buttons on emulator

Solution The problem was caused by Google Maps Android API v2 not being supported on emulator. Using a real device for testing solved the problem.

Question I am trying for google map, I got API key from Google. But when I run an application it shows blank white screen with zoom buttons

Here is my code - MainActivity.java 

public class MainActivity extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

}

Here is my XML file - activity_main.XML

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >

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

Here is Manifest.XML file 

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.demogooglemapv2"
    android:versionCode="1"

    <uses-feature android:glEsVersion="0x00020000"

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >

        <meta-data 
           android:name="com.google.android.maps.v2.API_KEY"
            android:value="AIzaSyB2jvxyj-WbkYc1Y1WR9Sc1E1W22QywA_k"
            />
        <activity
            android:name="com.example.demogooglemapv2.MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>
</manifest>

I find that if initially you happened to submit the androidManifest wrong. and once you corrected it and you verified that the It helps to remove your app from your device and let it install again from your IDE. somehow Android does cache that info.
