It says AndroidIAPP singleton not found

[GuacGameDev]

I downloaded this and put the android_IAPP (extracted) folder in my addons folder. When running the example for purchases as a singleton and I get the error message: "AndroidIAPP singleton not found"

I used Engine.get_singletons and this is what I get
["Performance", "TextServerManager", "PhysicsServer2DManager", "PhysicsServer3DManager", "NavigationMeshGenerator", "ProjectSettings", "IP", "Geometry2D", "Geometry3D", "ResourceLoader", "ResourceSaver", "OS", "Engine", "ClassDB", "Marshalls", "TranslationServer", "Input", "InputMap", "EngineDebugger", "Time", "GDExtensionManager", "ResourceUID", "WorkerThreadPool", "ThemeDB", "JavaClassWrapper", "JavaScriptBridge", "AudioServer", "CameraServer", "DisplayServer", "NativeMenu", "NavigationServer2D", "NavigationServer3D", "RenderingServer", "PhysicsServer2D", "PhysicsServer3D", "XRServer"]

Did you turn on it on project settings?

Did you turn on it on project settings?

i am having the same problems . when i extracted the files , it didnt create any folder named android_IAPP. so i went on and created a folder in my addons dir and put all four files in that directory . when i opened project settings -> plugins , i had the option to enable the plugin , did that and when i run my game it sends out error saying "AndroidIAPP singleton not found" , do i add the AndroidIAPP.gd script as singleton that came with the plugin ?

heres how my script looks like , and im using it as an autoload .

[GuacGameDev]

Did you turn on it on project settings?

Indeed! Like Protik, I too have it as an autoload and the addon enabled in product settings

Run it on android, the singleton doesn't work on desktop or laptop. The singleton will be found.

[alfredogarciaw]

Run it on android emulator with google play services
used adb logcat
09-27 18:20:12.369 10174 10332 I godot : AndroidIAPP singleton not found

Has the AndroidIAPP.gd to be added as autoload?
ChatGpt suggested to put the plugin on res://android/plugins could this work?

[Suthameow]

I am having the same problems, did anyone solve this issue?

[code-with-max]

@Suthameow
How you run your app?
Plugin will works only on Android with arm v8 platform

[Suthameow]

@code-with-max
I run my app on Sumsung note 8 and poco f6 pro. It says AndroidIAPP singleton not found. But google library 7.0 is working fine.

Could you please provide us a step by step link. (The AndroidIAPP plug in was checked.)

Thank you very much

[alfredogarciaw]

I made it work finally!
1)Test it in Closed testing (google play developer console) testing not in internal testing.
2)Don't release with debug option
3)Await 1 second
func iniciar_facturacion():
print("Intentando cargar singleton AndroidIAPP ")
await get_tree().create_timer(1).timeout
if Engine.has_singleton("AndroidIAPP"):
billing = Engine.get_singleton("AndroidIAPP")

func _on_connected() -> void:
await get_tree().create_timer(1).timeout
print("Conexión con Google Play Billing establecida.")
# Consultar detalles de productos disponibles
billing.queryProductDetails(ITEM_CONSUMABLES, "inapp")
# Consultar compras no consumidas
billing.queryPurchases("inapp")

@alfredogarciaw @code-with-max

Thank you, all.
I finally have passed the "AndroidIAPP singleton not found" issue.
My game has to run in the closed testing or Android remote debug.

Right now I met a new issue: "Invalid call. Nonexistent function 'purchase' in base "'JNISingleton'.""
It occurs when I click on the button that calls billing.purchase(purchase_id).

Thank you very much

[alfredogarciaw]

Remember to add ITEM_CONSUMABLES in google play console with price
Then look if your code looks like this
