I wanted to try the litho library from facebook for recycler view. Read the official docs and few other articles, and i started implementing using a basic example of hello world. But the app shows a white screen and crashes without displaying anything.
Searched online and few told to add multidex support, but multidex is by default enabled after sdk version 23. will attach my logcat for ref.
