title: Android Material and appcompat Manifest merger failed
body: <p>I have next grade     </p>
  
  <pre><code>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'
      implementation 'com.google.android.material:material:1.0.0-rc01'
  }
  </code></pre>
  
  <p>But when I want to build app I get next log:</p>
  
  <pre><code>Manifest merger failed : Attribute application@appComponentFactory value=(android.support.v4.app.CoreComponentFactory) from [com.android.support:support-compat:28.0.0-alpha3] AndroidManifest.xml:22:18-91
      is also present at [androidx.core:core:1.0.0-alpha3] AndroidManifest.xml:22:18-86 value=(androidx.core.app.CoreComponentFactory).
      Suggestion: add 'tools:replace="android:appComponentFactory"' to &lt;application&gt; element at AndroidManifest.xml:5:5-19:19 to override.
  </code></pre>
  
  <p>Okey! Go to manifest and do it:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;manifest xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:tools="http://schemas.android.com/tools"
      package="ru.chopcode.myapplication"&gt;
  
      &lt;application
          tools:replace="android:appComponentFactory"
          android:allowBackup="true"
          android:icon="@mipmap/ic_launcher"
          android:label="@string/app_name"
          android:roundIcon="@mipmap/ic_launcher_round"
          android:supportsRtl="true"
          android:theme="@style/AppTheme"&gt;
      &lt;/application&gt;
  
  &lt;/manifest&gt;
  </code></pre>
  
  <p>Then I get this error in my Logcat:</p>
  
  <pre><code>Manifest merger failed with multiple errors, see logs that I have Linked with it
  </code></pre>
