Google Map V2 Blank screen

Question

I'm currently developing an application using the Galaxy S3 with Android version 4.0, Ice Cream Sandwich. I followed Vogella's tutorial on how to use Google Map v2 for Android to create a sample map and it worked on Ice Cream Sandwich. Shows everything on the map. However when I try to access application's map activity on my friends Android device with version 2.3 Gingerbread I gets a blank screen with only the GPS button and zoom in and out button visible but on my phone it's running perfectly fine.

Manifest:

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

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="15" />

<permission
    android:name="com.example.mapApp.permission.MAPS_RECEIVE"
    android:protectionLevel="signature" />

<uses-permission android:name="com.example.mapApp.permission.MAPS_RECEIVE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.SET_DEBUG_APP" >
</uses-permission>

<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name="com.example.mapApp.HomeActivity"
        android:label="@string/title_activity_home" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity android:name="com.example.mapApp.MyMap" />

    <meta-data
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="MY API KEY" />
</application>

Layout:

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

Activity:

public class MyMap extends FragmentActivity{
private GoogleMap map;
@SuppressLint("NewApi")
protected void onCreate(Bundle savedInstanceState) 
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_map);
    SupportMapFragment FMap = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
    map = FMap
}}

Thank you.

You actually wrote that you made the changes which were suggested, but you had still problems... could you let us know, which was the last error message you received — Xavjer, Mar 19 '13 at 14:12
I've edited the question and my activity code as now I'm not getting a force close anymore but a blank screen with no error messages when running on Gingerbread. — user1832478, Mar 20 '13 at 11:27
Do you have a valid or correct map api key? Post your entire manifest file not just a portion of it. — Ariel Magbanua, Mar 20 '13 at 11:32
Yep I'm using a valid key as I am able to access the map activity without any problems on my device version ICS. — user1832478, Mar 20 '13 at 11:35
Post your entire manifest file, the problem is probably there. — Ariel Magbanua, Mar 20 '13 at 11:38

<meta-data
    android:name="com.google.android.maps.v2.API_KEY"
    android:value="my api key" />

Your Manifest Must be like Below :

<?xml version="1.0" encoding="utf-8"?>  
 <manifest xmlns:android="http://schemas.android.com/apk/res/android"  
   package="com.djandroid.mapsv2"  
   android:versionCode="1"  
   android:versionName="1.0" >  
   <uses-sdk  
     android:minSdkVersion="8"  
     android:targetSdkVersion="16" />  
   <uses-permission android:name="android.permission.INTERNET" />  
   <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />  
   <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />  
   <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />  
   <uses-permission android:name="com.djandroid.mapsv2.permission.MAPS_RECEIVE" />  
   <uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />  
   <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" >  
     <activity  
       android:name="com.djandroid.mapsv2.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>  
     <meta-data  
       android:name="com.google.android.maps.v2.API_KEY"  
       android:value="API_KEY" />  
     <uses-library  
       android:name="com.google.android.maps"  
       android:required="true" />  
   </application>  
 </manifest>

You are forgate this in your manifest file :

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

thats Why you may get below error in log:

Then error is : java.lang.RuntimeException: Google Maps Android API only supports OpenGL ES 2.0 andabove. Please add <uses-feature android:glEsVersion="0x00020000" android:required="true" /> into AndroidManifest.xml
