That's it! You're done! Now your custom menu will show up, you don't have to worry about the selection, and you barely have to concern yourself with the ActionMode lifecycle.
This works nearly flawlessly with a WebView that occupies its entire parent Activity. I am not sure how well it will work if there are multiple Views within your Activity at one time. It will likely require some tweaking in that case.

Android Studio - Dynamic Fragment crashing App

I am trying to link a Fragment, RecycleView and CardView using a variation of the tutorial found on:

Unfortunately my app crashes with the following error message:
"java.lang.IllegalStateException: RecyclerView has no LayoutManager"

I am fairly new with Android development. I tried to find similar issues on Stackoverflow but am unable to find the issue. Any help would be greatly appreciated!

 That's it! You're done! Now your custom menu will picture up, you don't take to worry about the selection, and you barely own to concern yourself with the ActionMode lifecycle. 
 This works closely flawlessly with a WebView that concern its entire parent action. I am not sure how well it will work if there be multiple Views within your Activity at one fourth dimension. It will probably require some tweaking in that case.
