清单合并失败：属性application @ appComponentFactory

我正在尝试实现Iconics库，但出现此错误。

Manifest merger failed : Attribute application@appComponentFactory value=(android.support.v4.app.CoreComponentFactory) from [com.android.support:support-compat:28.0.0-rc02] AndroidManifest.xml:22:18-91
    is also present at [androidx.core:core:1.0.0-rc02] AndroidManifest.xml:22:18-86 value=(androidx.core.app.CoreComponentFactory).
    Suggestion: add 'tools:replace="android:appComponentFactory"' to <application> element at AndroidManifest.xml:7:5-58:19 to override.

这是我的依赖项：

final String version= '28.0.0-rc02'
dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation "com.android.support:support-v4:$version"
    implementation "com.android.support:appcompat-v7:$version"
    implementation "com.android.support:design:$version"
    implementation "com.android.support.constraint:constraint-layout:1.1.3"
    implementation "com.github.GrenderG:Toasty:1.3.0"
    implementation "com.github.daniel-stoneuk:material-about-library:2.3.0"
    implementation "com.mikepenz:iconics-core:3.1.0-rc02"
    implementation 'com.mikepenz:community-material-typeface:2.7.94.1@aar'
}

我该怎么办？
