Library version: 0.10.0

Repro steps, stacktrace, screenshots:

  1. Assign any application's certificate footprint in uber developer's settings to enable SSO.
  2. Integrate the sdk in your project
  3. call LoginManager.login()

Expected Behavior: launching of Uber app with login activity

Real result: NPE crash

java.lang.NullPointerException: collection == null
        at java.util.ArrayList.<init>(

The cause is the default value of productFlowPriority collection which is null and therefore while constructing ArrayList it crashes the app.

I would like to know if it's ok to pass to setProductFlowPriority() Collections.emptyList() to bypass the crash ?

Yes, passing Collections.emptyList() should be fine. This will default you to using only the Uber app.

Thanks for the detailed issue report.
