    Woke up this morning to discover a new type of crash in the Android console. Something going on in Unity's purchasing code according to the stack (and I don't see any callback methods in there - appears to be all in the java code). It is apparently reproducible because it looks like the same user have the problem multiple times.

    Here are all the details I have:

    java.lang.Error: FATAL EXCEPTION [pool-14-thread-1]
    Unity version : 5.3.5f1
    Device model : samsung SM-T560
    Device fingerprint: samsung/gtelwifixx/gtelwifi:4.4.4/KTU84P/T560XXU0AOK1:user/release-keys
    Caused by: java.lang.NullPointerException

    We're not sure what would cause that error. Could you try an uninstall / reinstall of the Google Play store and clearing Google play app cache.

    The workaround would be to catch the exception and fail more gracefully.

    Unfortunately it is from an anonymous crash report shown on Android dev console. I don't have access to the device that's causing the trouble.

    Also, I'm not sure how I'd go about catching the expression? All the stack appears to be in java-land and running directly from the main thread. Any suggestion on how to do that?

    I have the same crash report on exactly the same device.
    I was wondering if there's any progress on the issue?

    This looks like it is a failure of Google's IAB Service. It might be worth submitting a bug report to their IAB github page or some other Google support area.

    It could be a low memory issue, where the billing service is killed to free memory and then throws errors when it the app tries to use it.
