Defects in IabHelper.java used for in-Android application billing, and solutions and workarounds.

IabHelper in the trivialdrivesample utility group, which is often cited as a common use for Android in-app billing, points to a problem that causes NullPointerException to occur at startup due to devices.

• IAB startSetup NullPointerException

Previously, Google updated the fix when there was another problem, but this problem still exists or has not been updated since the end of 2013.

We have already confirmed a similar error report on some LG devices in Japan.
Are developers currently implementing in-app billing implemented by themselves without using IabHelper?Or are you using another source code that solves the above problems?

I look forward to your kind cooperation.
