Google Maps v2 for Android not working on built apk

Hi I followed this documentation and It's working on my device when Im development stage. But when I package my app and install the apk on my device. The map is just blank. How can I enable to work this Google Maps v2 for my published/packaged apk?

My tiapp.xml:

<android xmlns:android="http://schemas.android.com/apk/res/android">
        <tool-api-level>15</tool-api-level>
        <manifest android:installLocation="preferExternal"
            android:versionCode="3" android:versionName="1.0.2">
            <uses-permission android:name="android.permission.INTERNET"/>
            <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
            <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
            <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
            <uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES"/>
            <uses-feature android:glEsVersion="0x00020000" android:required="true"/>
            <uses-permission android:name="***.permission.MAPS_RECEIVE"/>
            <permission
                android:name="net.proudcloud.NowShowing.permission.MAPS_RECEIVE" android:protectionLevel="signature"/>
            <uses-sdk android:minSdkVersion="7" android:targetSdkVersion="15"/>
            <application android:hardwareAccelerated="true" android:theme="@style/Theme.Action">
                <meta-data
                    android:name="com.google.android.maps.v2.API_KEY" android:value="*******"/>
                <activity android:configChanges="screenSize|orientation" android:name="org.appcelerator.titanium.TiActivity"/>
            </application>
        </manifest>
    </android>
