Can you put a code snippet of the code around line 132 in your Main Activity? That is where it is crashing and it will be helpful to have context.

dgonz7 commented 8 years ago

Ok I think I figured it out. Make sure that in your onCreate you call startLoggingApplicationStartup(). The reason it is failing is that that method wasn’t called. I’ll fix the error handling so that it gives a more useful message.

This was fixed in v2, closing this.
