InflateException when using TextInputLayout

Question

I'm trying to use TextInputEditText from Material Design (https://github.com/material-components/material-components-android/blob/master/docs/components/TextInputLayout.md) and I'm getting runtime exception.

This's part of run log:

E/AndroidRuntime: FATAL EXCEPTION: main               Process: com.example.grigori.materialtextedit, PID: 12036               java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.grigori.materialtextedit/com.example.grigori.materialtextedit.MainActivity}: android.view.InflateException: Binary XML file line #9: Binary XML file line #9: Error inflating class com.google.android.material.textfield.TextInputLayout                   at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2913)                   at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:3048)                   at android.app.servertransaction.LaunchActivityItem.execute(LaunchActivityItem.java:78)                   at android.app.servertransaction.TransactionExecutor.executeCallbacks(TransactionExecutor.java:108)                   at android.app.servertransaction.TransactionExecutor.execute(TransactionExecutor.java:68)                   at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1808)                   at android.os.Handler.dispatchMessage(Handler.java:106)                   at android.os.Looper.loop(Looper.java:193)                   at android.app.ActivityThread.main(ActivityThread.java:6669)                   at java.lang.reflect.Method.invoke(Native Method)                   at com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run(RuntimeInit.java:493)                   at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:858)                Caused by: android.view.InflateException: Binary XML file line #9: Binary XML file line #9: Error inflating class com.google.android.material.textfield.TextInputLayout                Caused by: android.view.InflateException: Binary XML file line #9: Error inflating class com.google.android.material.textfield.TextInputLayout                Caused by: java.lang.ClassNotFoundException: Didn't find class "com.google.android.material.textfield.TextInputLayout" on path: DexPathList 

I cut this log by DexPathList that contains many paths to apk files, like:

zip file "/data/app/com.example.grigori.materialtextedit-jamgTcrgG9neBKIMcqDo7Q==/base.apk" 

My xml file:

<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".MainActivity">  <com.google.android.material.textfield.TextInputLayout     android:layout_width="match_parent"     android:layout_height="wrap_content">      <com.google.android.material.textfield.TextInputEditText         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:hint="@string/hint_text"/>  </com.google.android.material.textfield.TextInputLayout> 

My build.gradle dependences:

    dependencies { implementation fileTree(dir: 'libs', include: ['*.jar']) implementation 'com.android.support:appcompat-v7:28.0.0-rc01' implementation 'com.android.support.constraint:constraint-layout:1.1.2' testImplementation 'junit:junit:4.12' androidTestImplementation 'com.android.support.test:runner:1.0.2' androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'}

Faced this issue when implementing AndroidX in my existing project.

implementation 'com.google.android.material:material:1.0.0-beta01' 

Layout XML

<com.google.android.material.textfield.TextInputLayout     android:id="@+id/userNameWrapper"     android:layout_width="match_parent"     android:layout_height="wrap_content"     android:theme="@style/TextLabel"> 

Old Style

<style name="TextLabel" parent="TextAppearance.AppCompat">         <item name="android:textColorHint">@color/hint_color</item>         <item name="android:textSize">@dimen/text_20sp</item>         <item name="colorControlNormal">@color/primaryGray</item>         <item name="colorControlActivated">@color/colorPrimary</item>     </style> 

New Style

<style name="TextLabel" parent="Widget.MaterialComponents.TextInputLayout.FilledBox">         <item name="android:textColorHint">@color/hint_color</item>         <item name="android:textSize">@dimen/text_20sp</item>         <item name="colorControlNormal">@color/primaryGray</item>         <item name="colorControlActivated">@color/colorPrimary</item>     </style>
