You get logs for your device from the Android Developer tool called ‘monitor’. Here’s the section about debugging, here’s how to read and write logs, and here is some command lines for logcat. You can use the command lines or if you want to shortcut monitor for later use it will be inside your NVPACK, somehere like this: C:\NVPACK\android-sdk-windows\tools
However, if you’re completely unable to package Tappy or anything, that means your SDK probably isn’t set up right. Please include the entirety of the failed build output logs for Tappy to this thread as a txt file so I can check the errors.
