Ideally, ImageTransitionLibrary should be layout-agnostic. Can you please provide the layout xml and relevant activity code that was causing the crash?

actually i was using coordinator layout inside toolbar when i pass transition view as an image view but after that i debug and found internally coordinator layout is going inside create animator instead of image view.after that i change coordinator layout into frame layout .every thing is working perfect . here is my toolbar layout put it inside your sample and test it. <?xml version="1.0"
