make sure in ur manifest as u added the google map library within the application tag instead of giving it outside.

<application android:icon="@drawable/icon" android:label="@string/app_name">
    <activity android:name=".GoogleMapView"
              android:label="@string/app_name">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <uses-library android:name="com.google.android.maps" />
</application>
<uses-permission android:name="android.permission.INTERNET"></uses-permission>

check if you have used the use-library for google map and permission for Internet in your manifest file and also have you used the debug key in xml .

Did you created the api key? and keep in mind that you need one key for debug certificate and a second key for the release android:apiKey="xxx" generate api key

Are you sure you have obtained a maps key from Google by generating a MD5 hash of your debug/release keys?

What's the output that you see , if you see any ?

Have you given InternetPermission to your app?
