Use

<uses-library android:name="com.google.android.maps" /> 

outside the activity tag but inside the application tag. For example:

<application android:icon="@drawable/icon" android:label="@string/app_name"> 
<uses-library android:name="com.google.android.maps" />     
    <activity android:name=".MapsActivity"
              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>
