Why am I getting a NullPointerException exception from Tealium in Android?

[jed_ashford]

When I first deploy our app to a device I get a NullPointerException. This only happens on the first install. If I background/restart the app there are no issues. I thought I may have been initializing too early, but I have this at the very end of the onCreate of the class in which we are extending the Application class. Maybe the TLC community can shed some light. Below is the both the Logcat and Tealium verbose logs.

Thank you for your question, it appears you are using the Full Tealium Library version 2.1. This is an auto-tracking conflict resolved in 2.1.2, which is available in Tealium's android-library github repository. As an additional note the Compact Tealium Library does not have auto-tracking, so if the auto-tracking doesn't meet your needs, that option is available to you as well.
