Odd Android Studio warning that seems ACRA related

[JMoore]

I am getting the warning below when I do a build of my app. Does anyone know what it means and whether it is a problem?

> Task :app:processDebugManifest
/Users/john/tvs/android-intellij/projects/Radar_Main/app/src/main/AndroidManifest.xml:39:9-45:51 Warning:
    provider#org.acra.attachment.AcraContentProvider@android:authorities was tagged at AndroidManifest.xml:39 to replace other declarations but no other declaration present
/Users/john/tvs/android-intellij/projects/Radar_Main/app/src/main/AndroidManifest.xml:39:9-45:51 Warning:
    provider#org.acra.attachment.AcraContentProvider@android:authorities was tagged at AndroidManifest.xml:39 to replace other declarations but no other declaration present

The manifest has the following clause. Line 39 is the first line inside this (anyDensity):

   <supports-screens
        android:anyDensity="true"
        android:largeScreens="true"
        android:normalScreens="true"
        android:resizeable="true"
        android:smallScreens="true"
        android:xlargeScreens="true" />

 
In build.gradle, ACRA is shown only in the dependencies clause:

dependencies {
    implementation 'com.google.android.gms:play-services-location:16.0.0'
    compileOnly "com.google.auto.service:auto-service:1.0-rc4"
    annotationProcessor "com.google.auto.service:auto-service:1.0-rc4"
    implementation "com.android.support:appcompat-v7:28.0.0"
    implementation 'com.android.volley:volley:1.1.1'
    implementation 'com.android.support:support-compat:28.0.0'
    implementation "ch.acra:acra-http:5.3.0"
    implementation "ch.acra:acra-toast:5.3.0"
    implementation "ch.acra:acra-limiter:5.3.0"
    implementation 'com.android.support:support-v4:28.0.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
}
