get meta data from manifest android

You can get meta data value from your android manifest. Simply writing two line of code.

Here, I caught the API_KEY from com.google.android.maps.v2.API_KEY meta data tag inside my application manifest file.
 ApplicationInfo ai = getPackageManager().getApplicationInfo(  
                          getPackageName(), PackageManager.GET_META_DATA);  
                ApplicationData.GoogleMapKey = ai.metaData  
                          .getString("com.google.android.maps.v2.API_KEY");
