NullPointerException

[ligao]

Hi Lorensius, Thanks for your great work.

I'm still using your July-16 commit and one of my users encountered the following exception. Has this been fixed in the latest release? Thanks!

You have any repro steps?

Sorry. I don't. This was reported by an anonymous user and I couldn't reproduce it on my handsets. Searching online I found a few people encountered similar issues. At least one of them looks like also related to QuickAction.

I think this issue might be related with ui thread. Do you perform a process in separated thread within quick action?

[xDragonZ]

I don't think so. I have emailed you my source code to lorenz [at] londatiga [dot] n e t, this might help you.

I always get same error reports from my users. For example:

manufacturer: unknown
model: rk29sdk
android version: 2.3.1
sdk version: 9
locale: pl_PL
