How To - Capturing Device Logs on Android

For troubleshooting and debugging, it is often very helpful to capture the device logs. The device logs contain information about the status of a running application on the device and any errors encountered. The IAP Engineering team requires logs for open issues. It is assumed here that you have an Android device configured with Developer options and attached to a PC with a USB cable. These steps show the process on a Windows system and works similarly on a Mac In Unity, find the location of …

A few questions:
*What are the Editor and IAP versions you use?
*Are you testing with a tester account, and downloading from Google Play? Did you download the APK as the tester from Google Play?
*Can you confirm that you have performed all the steps here?
Unity - Manual: Configuring for Google Play Store . Also, please compare to the Sample project here Sample IAP Project

• Can’t provide device log currently. sorry for that.
  -Unity Version 2019.1.2f1, IAP Latest (Install Through Package Manager)
  -Game downloaded from google play. No Tester.
  -Yes Confirmed.

This Temp Solution Worked For Me. “Someone said use IAP package of unity 2018—. Imported it in unity 2019—. And build. surprisingly its working now.”

You don’t install IAP via Package Manager, you install via the Service window (although there is a Package Manager package installed too). But glad it’s working for you.
