Android 5.0 (API 21) UnknownHostException:

Question

I am getting these error logs when the API is called from any device running Android 5 (API 21). Not sure if it's related to the networking library or any legacy issue with Android version 5 and below.

Log:

Before Android 4.1, method android.graphics.PorterDuffColorFilter 
androidx.vectordrawable.graphics.drawable.VectorDrawableCompat.updateTintFilter(android.graphics.PorterDuffColorFilter, android.content.res.ColorStateList, android.graphics.PorterDuff$Mode) would have incorrectly overridden the package-private method in android.graphics.drawable.Drawable

The log suggests that there is something to do with either Graphics or Network call.

Answer 1

There's no f78bc3d7.api.splkmobile.com host. Probably you've made a typo or were given a wrong address.

% ping f78bc3d7.api.splkmobile.com
ping: cannot resolve f78bc3d7.api.splkmobile.com: Unknown host
