The bug appears in crash logs; I have not reproduced it first hand. Possibly a bug in support library version 25.3.1. I am unsure if it affects other support library versions. Also do not know what Chrome version this affects.

String packageName = CustomTabsHelper.getPackageNameToUse(activity);

the packageName may be invalid as it is cached in CustomTabsHelper. Steps to reproduce:

1. Start the Activity where bindCustomTabsService is called.
2. Go to system settings and disable the Custom Tabs browser (eg. Chrome).
3. Resume the Activity and try opening the Custom Tab.
