Please [edit] your question to provide the complete [stack trace from the crash](https://stackoverflow.com/a/23353174). Please also have a look into how to create a [mcve]. Posting your entire project is never really necessary. — Mike M., Nov 21 '19 at 14:09

It'd be better if you post your XML here, instead of sharing the whole code. Share the part where you are using CoordinatorLayout — Kartik Shandilya, Nov 22 '19 at 03:43
@NovoLucas Check Above Code i have added xml file by editing this Question — atul chikane, Nov 22 '19 at 05:46
You need to add support design library to use CoordinatorLayout. Please add 'com.android.support:design:28.0.0' — Anand Jain, Nov 22 '19 at 10:04

Your project is AndroidX enabled, but you are not using AndroidX dependencies in your app level build.gradle. So, inside your project

Navigate to the Refactor menu
Click on Migrate to AndroidX

You might have to also make changes to your XML layouts-

Change android.support.design.widget.CoordinatorLayout to androidx.coordinatorlayout.widget.CoordinatorLayout and android.support.v7.widget.RecyclerView to androidx.recyclerview.widget.RecyclerView and likewise CardView to androidx.cardview.widget.CardView

I'd suggest you look into the Android Logcat for any errors or messages. Do some digging as to what is causing it to happen. – Kartik Shandilya Nov 22 '19 at 17:27
