Import statements giving errors after migrating to androidx, How to fix them?

Question

This import statements in the MainActivity are giving errors(after migration to androidx), what to do?

import android.support.design.widget.FloatingActionButton;
import android.support.design.widget.Snackbar;
import android.support.v7.widget.GridLayoutManager;
import android.support.v7.widget.LinearLayoutManager;
import android.support.v7.widget.RecyclerView;

import android.support.design.widget.NavigationView;
import android.support.v7.app.ActionBarDrawerToggle;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;

You have to replace the import statements to comply with AndroidX libraries version. For more details, check this: https://developer.android.com/jetpack/androidx/migrate — Sneh Pandya, Jun 18 '19 at 04:51
while migrating to androidx, package names should be changed in every class automatically, why that didn't happen? I'm confused. — Subhasish Nath, Jun 18 '19 at 04:57

Please remove your all appcompat-v7 and other implementation for androidx you need androidx libraries like below

import com.google.android.material.floatingactionbutton.FloatingActionButton
import androidx.appcompat.widget.Toolbar
import androidx.appcompat.app.AppCompatActivity

after migration, All the package names were supposed to be changed automatically, but that didn't happen. So now I have to do it manually for all packages? – Subhasish Nath Jun 18 '19 at 04:54

If your project is big then best approach is find and replace from whole project intend of changing on every single file. using `Shift` + `Ctrl` + `F` you can find from all file. – Vipul Prajapati Jun 18 '19 at 05:25

As Vipul Prajapati said, I manually changed all the package names by going to: https://developer.android.com/jetpack/androidx/migrate

searching for my existing package and then replacing by androidx specific ones.

I also made the following changes to my

gradle.properties

file.

android.useAndroidX=true
android.enableJetifier=true
