You need to use androidX dependencies like this:
import com.google.android.material.navigation.NavigationView;
import androidx.core.view.GravityCompat;
import androidx.drawerlayout.widget.DrawerLayout;
import androidx.appcompat.app.ActionBarDrawerToggle;
import androidx.appcompat.app.AppCompatActivity;
import androidx.appcompat.widget.Toolbar;
Make sure you have updated your app.gradle too
api 'androidx.appcompat:appcompat:1.1.0-rc01'
api 'com.google.android.material:material:1.1.0-alpha08'
You also need to add the following to gradle.properties
android.useAndroidX=true
android.enableJetifier=true
Once you update your gradles and delete the old dependencies Android Studio should find the new ones.

Add the support library to the dependency section.
implementation 'com.android.support:design:28.0.0'

How to know which Support Library version my Android app is using?

In my gradle.properties I have this:
android.useAndroidX=true
When I Make Project, I get BUILD SUCCESSFUL. From Android Studio, I go to Refactor > Migrate to AndroidX... I am getting 15 references in 9 files to be changed:
Reading https://medium.com/androiddevelopers/migrating-to-androidx-tip-tricks-and-guidance-88d5de238876, I see that the step 1 of the recommended approach to migrate is to Update to Support Library version 28. In order to do that, I want to know what Support Library version the code of my app is at. Where can I see that? In some of my .java files I have found the following:
import android.support.annotation.NonNull;
import android.support.v4.app.NotificationCompat;
import android.support.v7.app.AppCompatActivity;
import android.support.v4.content.ContextCompat;
import android.support.v4.app.ActivityCompat;
import android.support.v4.app.FragmentActivity;
import android.support.multidex.MultiDex;
In my app\build.gradle I have this: implementation 'com.android.support:multidex:1.0.3'.
Do any of the lines above reveals or helps to reveal the Support Library version that the code of my app is at? Thank you.
What it means is that they suggest upgrading all of the possible support libraries to 28.0.
Those are basically anything that starts with com.android.support:
e.g.:
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support:cardview-v7:28.0.0'
implementation 'com.android.support:gridlayout-v7:28.0.0'
The recommendation there is so the migration in the AS will have to do minimal guessing on how to migrate it.
So to stricly answer your question, the version you use is the version you have in gradle.files.

Is the Material Design NavigationView not yet compatible with AndroidX?

I just converted my App from the support library to AndroidX. Everything compiles now and the App starts successfully. However one of my activities uses com.google.android.material.navigation.NavigationView which seems to still depend on the old support library. Specifically I see dependencies on the following classes if I look into the code of NavigationView:
import android.support.annotation.DimenRes;
import android.support.annotation.Dimension;
import android.support.annotation.DrawableRes;
import android.support.annotation.IdRes;
import android.support.annotation.LayoutRes;
import android.support.annotation.NonNull;
import android.support.annotation.Nullable;
import android.support.annotation.RestrictTo;
import android.support.annotation.StyleRes;
import com.google.android.material.internal.NavigationMenu;
import com.google.android.material.internal.NavigationMenuPresenter;
import com.google.android.material.internal.ScrimInsetsFrameLayout;
import com.google.android.material.internal.ThemeEnforcement;
import android.support.v4.content.ContextCompat;
import android.support.v4.view.AbsSavedState;
import android.support.v4.view.ViewCompat;
import android.support.v4.view.WindowInsetsCompat;
import android.support.v7.content.res.AppCompatResources;
import android.support.v7.view.SupportMenuInflater;
import android.support.v7.view.menu.MenuBuilder;
import android.support.v7.view.menu.MenuItemImpl;
import android.support.v7.widget.TintTypedArray;
In my apps build gradle I depend on:
implementation "androidx.appcompat:appcompat:1.0.2"
implementation "com.google.android.material:material:1.1.0-alpha01"
Since I am using the new dependency to the material design library (which is the one also given my the AndroidX migration guide), I was expecting all the classes having the correct dependencies. Am I wrong here? Is this not ready yet? Does someone have any additional insights I am missing?
I was also facing the same issue, for me adding following dependency in gradle worked.
implementation 'com.google.android.material:material:1.0.0'
EDIT latest stable version available is:
implementation 'com.google.android.material:material:1.3.0'

Android studio doesnt recognize some libraries.(import statements)

Android studio does not recognize some import statements like
import org.jivesoftware.smack.Chat;
import org.jivesoftware.smack.ChatManager;
But it recognizes some import statements like
import android.text.TextUtils;
import android.view.KeyEvent;
How can I fix it?
Ensure you have added the necessary dependency in your gradle file and have done a gradle sync to download the required packages
compile 'org.igniterealtime.smack:smack-android:4.1.8'
compile 'org.igniterealtime.smack:smack-tcp:4.1.8'
This worked for me

cannor resolve symbol "baidu" android studio

import com.baidu.android.pushservice.PushConstants;
import com.baidu.android.pushservice.PushManager;
I am unable to import the above libraries into my android application.
What dependencies should I add in the build.gradle in order to import them?

Cannot resolve symbol 'android' in Import

I am getting error in Android Studio. My import:
imports com.google.android.gms.common.api.GoogleApiClient;
import com.google.android.gms.common.api.GoogleApiClient.ConnectionCallbacks;
are not working.
Use
import com.google.android.gms.common.api.GoogleApiClient;
instead of imports to import a class.
Download new version of google-play-services library.
Always update/download newest version of google-play-services library.
you must add
compile 'com.google.android.gms:play-services-location:7.8.0'
in dependencies block, in app/build.gradle.
also update google play in sdk manager
