问题 I am planning to make an equalizer app for Android. I noticed in the Equalizer class documentation here, it says: NOTE: attaching an Equalizer to the global audio output mix by use of session 0 is deprecated. I see from other questions that although this is deprecated, it was still possible in certain Android versions; however the most recent answer is from 2013.

Then, when you call startActivity you have to pass a Bundle to that function that you obtain by calling ActivityOptions.makeSceneTransitionAnimation(getActivity()).toBundle() .

Also a SlidingMenu of Feinstein is added and that causes the problem that the that the Activity (and therefore the inside Fragments) overlap with the navigation buttons of Android (it is not fully shown, cut off at the bottom) if i add: android:layout_marginBottom="48dp" in the layout it everything is visible (of course).
