While calling getRoute method on navigation instance, I am having following error:

onFailure: navigation.getRoute()
   java.lang.IllegalArgumentException: Unexpected char 0x2122 at 27 in User-Agent value: TODO Linux/3.18.88-Reloaded™ (aarch64)

Dependecies I am using:

compile ('com.mapbox.mapboxsdk:mapbox-android-sdk:5.2.1@aar'){
       transitive=true
   }
   compile 'com.mapbox.mapboxsdk:mapbox-android-navigation:0.8.0'
   implementation ('com.mapbox.mapboxsdk:mapbox-android-navigation-ui:0.8.0') {
       transitive = true
   }

Android Version: 8.1

UPDATE:

It seems device specific. My Custom ROM's kernal name includes unicode "TM" symbol. That is causing crash!

in User-Agent value

Like mentioned above, this is due to a non-ASCII char (™) in the User-Agent field. We should add a TextUtil to remove any of these characters inside and add it somewhere in the getHeaderUserAgent method.
