kulichin / unrealandroidplaybilling Goto Github PK

Hello I wanted to know if there were a reason for using a UGameInstanceSubsystem for the UAndroidPlayBillingSubsystem instead of UBlueprintFunctionLibrary as all functions inside are static

Looks like there is a bug on line 440 in AndroidPlayBillingSubsystem.cpp. Please replace IsIAPInitialized_MethodID to IsPurchased_MethodID.

bool UAndroidPlayBillingSubsystem::IsPurchased(const FString& ProductID)
{
#if PLATFORM_ANDROID
	if (JNIEnv* Env = FAndroidApplication::GetJavaEnv())
	{
		auto JProductID = FJavaHelper::ToJavaString(Env, ProductID);
		
		// Call Java method
--->		return CallBooleanMethod(Env, IsIAPInitialized_MethodID, *JProductID);
	}
#endif

	return false;
}

Any new on when it's going to be available on unreal 5.1? thanks!

Calling Query SkuDetails causes crash with error:

Fatal signal 6 (SIGABRT), code -6 (SI_TKILL) in tid 13251 (PlayBillingLibr)

PS: do have same issue with OnlineSubsystem GooglePlay buildin plugin. (though there it crash only in armv7 build not arm64)

Hi,

I found that it will crash on QuerySkuDetail.
It caused by "'Primitive char conversion on invalid type 0’"
It can fix by update AndroidPlayBillingSubsystem.cpp

- int IntroductoryPriceCycles			= GetScopedStringFromObject(Env, Object, SkuDetailsRecord_IntroductoryPriceCycles_FieldID);
+ int IntroductoryPriceCycles			= (int)Env->GetIntField(Object, SkuDetailsRecord_IntroductoryPriceCycles_FieldID);

I hope this article can help someone.

Thanks.

Using UE 5.0 with the latest version of the plugin and I get this error while trying to package my game for android

Z:\app\src\main\java\com\android\vending\billing\util\IabHelper.java:476: error: cannot find symbol
UATHelper: Packaging (Android (ETC2)): String sku = purchase.getSkus().get(0);
UATHelper: Packaging (Android (ETC2)): ^
UATHelper: Packaging (Android (ETC2)): symbol: method getSkus()
UATHelper: Packaging (Android (ETC2)): location: variable purchase of type Purchase

As mentioned here: https://developer.android.com/google/play/billing/deprecation-faq?hl=en

Google Play Billing 4.X is now deprecated since August 1st 2023 and we need to move on to the 5.0.
I would like to know if any update about this is planned so far? Thanks!

The in app purchases work just fine. But I cannot seem to fetch all the available IAP and their SKU details. The response, despite being OK, returns empty. I just want to fetch the details so that I can update the pricing and values in the UI for the user according to their country.

Add GooglePlayBilling dependency to PublicDependencyModuleNames in your {ProjectName}.Build.cs file (located in Source{ProjectName}\ directory).

Don't you mean

PublicDependencyModuleNames.Add("AndroidPlayBilling");

Hi!

I found another nasty bug.

The type of IntroductoryPriceCycles field is integer. But this field obtained as string which causes the program to crash in Development mode. This bug in function GetSkuDetailsRecordStructFromJavaObject in file AndroidPlayBillingSubsystem.cpp on line 251.

	int64 IntroductoryPriceAmountMicros	= (int64)Env->GetLongField(Object, SkuDetailsRecord_IntroductoryPriceAmountMicros_FieldID);
	auto JIntroductoryPricePeriod		= GetScopedStringFromObject(Env, Object, SkuDetailsRecord_IntroductoryPricePeriod_FieldID);
-->	int IntroductoryPriceCycles		= GetScopedStringFromObject(Env, Object, SkuDetailsRecord_IntroductoryPriceCycles_FieldID);
	auto JIconURL				= GetScopedStringFromObject(Env, Object, SkuDetailsRecord_IconURL_FieldID);

Also for the UE4 engine it is better to use the int32 type instead of int.
