title: Where is the Order and Export tab in Android Studio 2.x?
body: <p>After updating Android Studio 2.1.2 apps running on my local device now fatal errors with "java.lang.RuntimeException: Unable to instantiate activity ComponentInfo{today.trsc.songs/today.trsc.songs.MainActivity}: java.lang.ClassNotFoundException: Didn't find class". But the MainActivity is there in the IDE. Others with this problem suggested updating java libraries in "Order and Export" but that's an Eclipse feature; where is that in Android Studio 2.x? There is no "Properties" choice when right-clicking on Project. </p>
