Godot Version
4.6.1
Question
Hello everyone,
I’ve been stuck with the GodotGooglePlayBilling plugin (v3.2.0) on Godot 4.6.1 for about a month now and I can’t figure out what’s wrong.
The problem:
The plugin is correctly detected (I can access it via the singleton), but none of the signals are ever triggered — not even connected or disconnected. It looks like startConnection() does nothing.
What I already checked:
-
Plugin enabled in Project Settings
-
Gradle build enabled in Android export
-
Tested on a real device
-
App uploaded to Google Play Console (internal testing track)
-
App installed via Play Store (not via APK)
-
Tester account configured
Logs (adb logcat):
I can see the plugin initialization:
-
“Initializing Godot plugin GodotGooglePlayBilling”
-
“Completed initialization for Godot plugin GodotGooglePlayBilling”
But after calling startConnection(), nothing else appears:
-
No BillingClient logs
-
No connection attempt
-
No error
My code:
func _ready() -> void:
await get_tree().process_frame
getBillingPaid()
func getBillingPaid():
if Engine.has_singleton("GodotGooglePlayBilling"):
print("in here!")
$Label.text += "\n\n\nTest item SKU: %s" % TEST_ITEM_SKU
payment = Engine.get_singleton("GodotGooglePlayBilling")
$Label4.text = str(payment)
payment.connected.connect(_on_connected)
payment.disconnected.connect(_on_disconnected)
payment.purchases_updated.connect(_on_purchases_updated)

"get.10000.stars_fute"
], payment.TYPE_INAPP)
func _on_QuerySkuDetailsButton_pressed():
payment.querySkuDetails([TEST_ITEM_SKU], payment.TYPE_INAPP)
Does anyone have any idea why no signal would be triggered at all?
Is there something I might be missing in the setup or configuration?
Thanks in advance.
