When I migrated to AndroidX I am getting java.lang.RuntimeException: Unable to start activity ComponentInfo

Question

Recently I pushed the app to live and it was'nt working on android 9 & above. So, I upgraded android studio to 2020.3.1, updated the plugins, migrated code to AndroidX. Since then I am facing following issue.

Here is the error at runtime

E/AndroidRuntime: FATAL EXCEPTION: main

    title = toolbar.findViewById(R.id.tv_tittle);
    toolbar.findViewById(R.id.Main_navBtn).setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            drawerFragment.openDrawerFrag();
        }
    });
    toolbar.setNavigationIcon(null);
    toolbar.setContentInsetsAbsolute(0, 0);
    setSupportActionBar(toolbar);
    getSupportActionBar().setDisplayHomeAsUpEnabled(false);

    userPref = new AppPreferences(this);

    DrawerLayout mDrawerLayout = findViewById(R.id.drawer_layout);
    drawerFragment.setUp(R.id.fragment_navigation_drawer, mDrawerLayout);
    drawerFragment.setDrawerListener(MainActivity.this);

    displayView(0);
}

I can't figure out how to fix this. Any suggestions?

Seems to be some issue with the class CalligraphyLayoutInflater. Are you using some third party library?If yes then has it been migrated to AndroidX? — gtxtreme
I am using a dependency. implementation 'uk.co.chrisjenx:calligraphy:2.2.0' — Kiran Rai Chamling

Version of Calligraphy you are using is outdated, you need to update the Calligraphy 3 to support android 10 and above. Refer to this link:
https://github.com/InflationX/Calligraphy

When I migrated to AndroidX I am getting java.lang.RuntimeException: Unable to start activity ComponentInfo
