NPE on auto-test done by Google

[CyrilleGuimezanes]

Hello,

When I publish my app, Google starts auto-test on various devices. Since two releases Google give a NPE with this stack trace:

java.lang.NullPointerException: Attempt to invoke interface method 'android.os.Bundle com.android.vending.billing.IInAppBillingService.getBuyIntent(int, java.lang.String, java.lang.String, java.lang.String, java.lang.String)' on a null object reference
 	at com.smartmobilesoftware.util.IabHelper.launchPurchaseFlow(IabHelper.java:386)

 	at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:587)
 	at java.lang.Thread.run(Thread.java:818)

In a physical use, no exception...

Google told me that the tested device is Galaxy S6 under Android 5.1. Others 5.1 devices pass all the tests.

Thanks for pointing out this issue. 👍

I'll try to have a look at this this week.

@CyrilleGuimezanes By the way, do you have any JS code to share that could help reproduce/understand this issue?

[CyrilleGuimezanes]

Actually it's a really simple use of your plugin and in a normal use (when I use my phone under android 6.0), it not crash

Here is the logcat attached to Google bug report if that can help:

Hello,
Thanks for the logcat file! I tried to trace back your error but I couldn't find why you have this exception as everything seems to be properly initialized.
As I have no way to reproduce it currently, would you be able to make a new build with debug logs activated in IabHelper and attach the resulting logs?
This can be done either by:

• directly replacing IabHelper.java l.74 by: boolean mDebugLog = true;
• or adding in WizPurchase.java l.359 this line: mHelper.enableDebugLogging(true);
