Inflation exception when using Java 8 dependency

[mpowloka]

UPDATE: Some time after posting this issue I found it is because of Java 8 dependency in the project. Removing it removed the issue. Although this is still a problem to look into.

compileOptions { sourceCompatibility JavaVersion.VERSION_1_8 targetCompatibility JavaVersion.VERSION_1_8 }

I make a simple test application with MaterialCalendarView in fragment and I get following exception. It leads nowhere to my code. The calendar is placed in fragment and I use AndroidX if that is relevant.

I use the latest library version. Ask me for any further info as necessary.

We are also facing same issue. Any solution for this.

Caused by: android.view.InflateException: Binary XML file line #78: Error inflating class com.prolificinteractive.materialcalendarview.MaterialCalendarView

seems this solution you mentioned not working, are you using 2.0.1 which is latest?
