Thanks for reporting, I can't reproduce it yet. What is your testing device?

[mrhether]

Motorola-Moto-G-2nd-Gen-XT1063 4.4.4.
This was through Crashalytics.

@sockeqwe: It occured when you use it to display an image in an activity. Then you use 3 or 4 fingers to zoom out and in: Keep a finger touch, use 2 or 3 fingers to zoom (in & out). The same log with @mrhether
My testing device: Samsung Galaxy S5, Android 5.0
Please check and fix it, looking forward to see.
Thank in advance!! :)

[sockeqwe]

Thanks for reporting, I will check that

Should be fixed with version 1.0.4
