My app was crashing when I tried to create a notification. For my case, I was using an Android Studio sample project, "Basic Activity" that contained the AndroidManifest.xml below. The mipmap/ic_launcher and mipmap/ic_launcher_round are used as app icon.

<application
    android:name=".DriveMeApp"
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:roundIcon="@mipmap/ic_launcher_round"
    android:supportsRtl="true"
