Best practice on Android is not to implement your own custom search, but to hook into the system-wide search: http://developer.android.com/guide/topics/search/adding-custom-suggestions.html. Otherwise your app will feel like it doesn't integrate well into Android. (The system-wide search, of course, is already hooked up to Google search.)
