  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.

#8: What I mean to say is "not *by default* on Win7" (as opposed to Win10, where it is installed by default).

It's not even that. You get it if you take any updates at all. You don't
have to specifically install it.

The SDK platform tools update at a different cadence from the IDE, so I'm hesitant to call it out in the WNA. Do we have an idea of how users this affects?

Looking at https://studio-stats.corp.google.com/#report_id=Studio/Usage/By%20OS%20Version, it's hard to tell what percentage of the W7 6.1 users are on SP1.

Considering that it's already included in the sdk tools release notes, do you think another useful place is the ADB Connection assistant?

#11: I don't have more data related to how many users would be affected.

One option would be connection assistant, another option would be to create a new system health check (specific to Windows) that would ensure that the universal c runtime is installed on the machine.

Happy to help you draft any UI text :)

FYI: See b/128869875: We are getting regular bug reports from Windows 7 users for this issue. It started March 17th, and we already have 33 duplicates. This is significant inflow.

I opened b/129776958 to track implementation of the system health check.
