Fabric initialization could not calculate hash for app icon in case of Android Instant Apps

Question

I am initializing Fabric in Application class as

Fabric.with(context, crashlyticsKit);

My project is divided into three modules - base feature module, apk-wrapper module and an instant-app module. App Icon is declared as application attribute in AndroidManifest.xml of base feature module.

At startup of Instant app, Fabric throws following error

E/Fabric: Could not calculate hash for app icon.

Ok, so it looks like you’ve already seen https://stackoverflow.com/questions/30606527/twitter-no-package-identifier-when-getting-value-for-resource-number-0x00000000. Double check your setup https://stackoverflow.com/questions/44361850/how-do-i-integrate-crashlytics-with-android-instant-apps and make sure you are on the latest version 2.6.8 https://fabric.io/kits/android/crashlytics/install — TWL, Aug 08 '17 at 00:22

This is a known issue with Fabric + Instant Apps. It's not critical though and will only mean your console will not be able to display your app icon.

Go over the app icons and make sure your app has the proper launcher icon for all versions (both android:icon and android:roundIcon )

Make sure to have a proper fallback to versions below 26 if you use adaptive icons.

Simply add an app icon in your manifest like so:

<application
        android:name=".MyApplication"
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher" <----- add this
        android:label="@string/app_name"
        android:theme="@style/AppTheme">
        ...
        ...
        ...
</application>
