52.5 Reviewing the Application Manifest File

In order for MainActivity to be able to launch ActivityB using an intent, it is necessary that an entry for ActivityB be present in the AndroidManifest.xml file. Locate this file within the Project tool window (app -> manifests), double-click on it to load it into the editor and verify that Android Studio has automatically added an entry for the activity:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

    <application

        android:allowBackup="true"

        android:icon="@mipmap/ic_launcher"

        android:label="@string/app_name"
