During tests, activities were not closed properly causing increasing
memory usage, which resulted in failing tests because of
out of memory errors.
This has been fixed by using the test orchestrator which runs
each test in its own instrumentation instance.
Removed the instrumentationTest flavor and replaced it by using the
default debug build type. The flavor was used to keep the required
permissions during testing separate from release versions. This can
also be accomplished using the debug build type.
The PagerSlidingTabStrip from astuetz doesn't work with the new
android build tools. As the project seems dead, I replaced it with
PagerTabStrip from the support library.
Added SharedElementCallback to be able to detect if shared element
is still visible. If not, the shared element transition should not
be performed when returning to the previous fragment.
Added the pager tab strip to the fade animation to keep shared element
transition smooth when poster is partly below the toolbar.
* Refactored OnMovieSelectedListener interface to keep argument list small.
* Changed fragment transition animation to make shared element transition
smooth and nicely integrated with the whole scene animation.
