[25RBazookas]

The PagerSlidingTabStrip crashes on a Samsung S7 Edge in the onDraw method.

crashes on canvas.DrawRect(paddingLeft, height - underlineHeight, tabsContainer.Width + paddingRight, height, rectPaint); //This line crashes

It seems that Paint rectPaint; is disposed on the moment that the OnDraw method is called.

Had crash on Nexus 5 (Android 6 ) and Samsung S7 Edge (Android 7)

Do you have a small sample to look at?

Also, this library has now been deprecated by the new Android Support Design Library. Please see the full component for a sample: https://components.xamarin.com/view/xamandroidsupportdesign

Hello James
I will make a sample project which I will provide in the following days.

My app crashes if I return from an activity to the activity with the pagerslidingtabstrip. I suspect that the GarbageCollector will be a problem here.

I've tested your sample and it does not crash even if I open multiple activities. I'll keep you posted.
