Modified calls to onShow(height) and onDismiss(height) so they both occur when the action is starting and they both provide an exact height in pixels instead of a maximum height. This helps in implementing floating action buttons movement with respect to the snackbar as specified in the material guidelines.

Also removed some unneeded calls to dpToPx().
Minor fix to text messages
Updated Android Gradle Plugin
mOffset is now retrieved with resources.getDimensionPixelOffset() instead of resources.getDimensionPixelSize()
