Modify AndroidManifest.xml for Google Maps Android API v2

To use Google Maps Android API v2 on your app, you have to modify your AndroidManifest.xml as listed below:

Insert <meta-data> element to include API key as a child of the <application>

<meta-data
android:name="com.google.android.maps.v2.API_KEY"
android:value="--- your API Key here ---"/>

Remember to replace value with your own API Key.

Please notice that you have to use debug API Key (refer to "Generate Debug API Key for Google Maps Android API v2 service") in your testing. And then replace with release API key (refer to "Create and Obtain API Key for Google Maps Android API v2 service") in your release APK.
Add <permission> and <uses-permission> of MAPS_RECEIVE.

<permission
android:name="com.example.androidmapsv2.permission.MAPS_RECEIVE"
android:protectionLevel="signature"></permission>
<uses-permission
android:name="com.example.androidmapsv2.permission.MAPS_RECEIVE"/>

where com.example.androidmapsv2 is my package, replace with your own package name.
Add uses-permission:

<uses-permission
android:name="com.google.android.providers.gsf.permission.READ_GSERVICES"/>
<uses-permission
android:name="android.permission.INTERNET"/>
<uses-permission
android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

and optional:

<uses-permission
android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission
android:name="android.permission.ACCESS_FINE_LOCATION"/>
Specify uses-feature of OpenGL ES 2:

<uses-feature
android:glEsVersion="0x00020000"
android:required="true"/>

Finally, the AndroidManifest.xml will like it:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.androidmapsv2"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="16" />
    
    <permission 
        android:name="com.example.androidmapsv2.permission.MAPS_RECEIVE" 
        android:protectionLevel="signature"></permission>
    <uses-permission 
        android:name="com.example.androidmapsv2.permission.MAPS_RECEIVE"/>
    <uses-permission 
        android:name="com.google.android.providers.gsf.permission.READ_GSERVICES"/>
    <uses-permission 
        android:name="android.permission.INTERNET"/>
    <uses-permission 
        android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
    <uses-permission 
        android:name="android.permission.ACCESS_COARSE_LOCATION"/>
    <uses-permission 
        android:name="android.permission.ACCESS_FINE_LOCATION"/>
    
    <uses-feature
        android:glEsVersion="0x00020000"
        android:required="true"/>
    
    <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="--- your API Key here ---"/>
        <activity
            android:name="com.example.androidmapsv2.MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
