					I am developing a google maps app for android.  But, somehow my application crashes giving an error like :  java.lang.IllegalStateException: A required meta-data tag in your app's AndroidManifest.xml
				
				
			 
		 
	 
Error:
com.google.android.gms.common.GooglePlayServicesMissingManifestValueException: A required meta-data tag in your app's AndroidManifest.xml does not exist.  You must have the following declaration within the <application> element:     <meta-data android:name="com.google.android.gms.version" android:value="
@Integer/google_play_services_version" />
Solution:
That is, inclue this in manifest:
AddApplicationText(<meta-data android:name="com.google.android.gms.version"
      android:value="
@Integer/google_play_services_version" />    )
