Hi! I am writing an Android game and I need to add in-game purchases.
In the Android in-game purchases docs I found an example.
I downloaded the project, plugin. Installed custom build and connected the plugin (I copied GodotGooglePlayBilling.1.0.0.release.aar, GodotGooglePlayBilling.gdap in android/plugins folder and In export settings enabled the plugin). But when I try to run the game via usb on my phone - I have an error: “ERROR: Couldn’t find singleton for class: org/godotengine/godot/GodotGooglePlayBilling.”
Godot version 3.2.2
So, would be glad to get help.
