Crash on API 15
My app is crashing for devices on API 15 (4.0.3) when mTutorialHandler.next() is called in my TourGuide sequence. I would appreciate any insight as to why this might be happening. This code is now in production, so I would really like to figure it out!

Same here, everything works fine on Lollipop but crashes on ICS.

mExitAnimation.setFillAfter(true);
// the return handler is used to manipulate the cleanup of all the tutorial elements

.setToolTip(new ToolTip()
.setTitle(getString(R.string.tutorial1_title))
.setDescription(getString(R.string.tutorial1))
.setGravity(Gravity.CENTER)
)
// note that there is not Overlay here, so the default one will be used
.playLater(screenCenter);
TourGuide tourGuide2 = TourGuide.init(this)
.setToolTip(new ToolTip()

.setDescription(getString(R.string.tutorial2))

Sequence sequence = new Sequence.SequenceBuilder()
.add(tourGuide1, tourGuide2, tourGuide3)
.setDefaultOverlay(new Overlay()
.setEnterAnimation(mEnterAnimation)
.setExitAnimation(mExitAnimation).setBackgroundColor(Color.parseColor("#8800796B")).setStyle(Overlay.Style.Rectangle)
)
.setDefaultPointer(null)
.setContinueMethod(Sequence.ContinueMethod.Overlay)
.build();
TourGuide.init(this).playInSequence(sequence);
Still not fixed on ICS (API 15) any updates?

I had the same problem, and I found that it's caused by the Overlay exit animation. Don't set any exit animation for Android API 15, and it's fixed!
