showing a message dialog only once , when application is launched for the first time in android
<p>I've developed an application in android and one of the important requirements is to show  a message dialog  for language support ONLY when the application is running for the first time ,then it will disappear each time the user is running the application again , I've tried to use shared preferences but it didn't work , is there is any other way to do that ?? </p>
