  error: failed linking file resources.

If it's Gradle issuse, then I tried with 5.2.1-all and same happens.

it's an issue with your application, looks like you are referencing @string/appbar_scrolling_view_behavior but do not define it in your resources.

No, the resource is within Android Library itself, and we implement it in xml by app:layout_behavior="@string/appbar_scrolling_view_behavior". But as of Android Studio 3.4-RC1, it seems to be fixed.:)

I'm sorry but it seems to persist. I'm posting a xml layout:

<?xml version="1.0" encoding="utf-8"?>
<layout 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">

    <androidx.coordinatorlayout.widget.CoordinatorLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <com.google.android.material.appbar.AppBarLayout
            android:id="@+id/appbar"
            style="@style/AppTheme.AppBarStyle"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:theme="@style/AppTheme.AppBarOverlay">

            <androidx.appcompat.widget.Toolbar
                android:id="@+id/toolbar"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                app:layout_scrollFlags="scroll|enterAlways|snap"
                tools:title="@string/app_name" />
        </com.google.android.material.appbar.AppBarLayout>

        <androidx.recyclerview.widget.RecyclerView
            android:id="@+id/message_recyclerView"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:contentDescription="@string/message_selection_view"
            android:shadowColor="@color/grey_800"
            app:layout_behavior="@string/appbar_scrolling_view_behavior" />

        <com.google.android.material.floatingactionbutton.FloatingActionButton
            android:id="@+id/fab"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="bottom|end"
            android:layout_margin="@dimen/dp_16"
            android:visibility="invisible"
            app:backgroundTint="@color/white"
            app:rippleColor="?attr/colorControlHighlight"
            app:srcCompat="@drawable/ic_cloud_upload"
            app:tint="@color/colorAccent" />
    </androidx.coordinatorlayout.widget.CoordinatorLayout>
</layout>

As you can see within the RecyclerView that I've used the string resource and it's giving me the error.

Gradle: gradle-5.2.1-all.zip
Project level:
buildscript {
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.4.0-rc01'
    }
}
Modules:
dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation 'androidx.appcompat:appcompat:1.1.0-alpha02'
    implementation 'com.google.android.material:material:1.1.0-alpha04'
    implementation 'androidx.constraintlayout:constraintlayout:2.0.0-alpha3'
    implementation 'androidx.recyclerview:recyclerview:1.1.0-alpha02'
   ...

Another example of AS 3.4 RC 1:

<androidx.core.widget.ContentLoadingProgressBar
                android:id="@+id/progress_bar"
                style="@style/Widget.MaterialProgressBar.ProgressBar.Horizontal.NoPadding"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:max="100"
                android:progress="1"
                android:progressTint="@color/colorPrimary" />

Error I'm getting: Can't resolve symbol '@style/Widget.MaterialProgressBar.ProgressBar.Horizontal.NoPadding'

Gradle: gradle-5.1.1-all

Dependencies are same as above. While with latest AS 3.3.2, I'm getting no such error and clicking it, takes me to Android's resource file of values.xml.

P.S. "looks like you are referencing @string/appbar_scrolling_view_behavior but do not define it in your resources.", I would like to add that it compiles perfectly!

Let's track this in the other bug.

It will be included on 4.0 beta 1. It is worth mentioning that you will see a warning message but it will be different.

Thank you for the update!
