SmoothProgressBar isn't directly needed, and the version number was too high for ActionBar-PullToRefresh, causing crashes.
Bumped ActionBar-PullToRefresh to 0.9.3 (for fixing a swiping bug), swtiched to standard flavor rather than ActionBarCompat one, which we don't need.
(Please empty your .idea/libraries folder if you run into any issue)
