I'm currently developing an Android-app, in which I have already implemented an Slidingmenu (jfeinstein10's library). As above-views I have several activities I'd like to switch between with the menu-items in my Slidingmenu. For the most part, these activities consist of two fragments, a list and a content-view. In landscape-mode both are displayed, in portrait-mode only the list. Currently I'm switching between these activities with intents, which is not a very pretty "solution". How should I implement this? Thanks in advance.
