Subject: Urgent: Google Play Billing Library 7.0.0+ integration in .NET MAUI (.NET 9) – No official NuGet package or binding available (Subscriptions) #30405
-
|
Hello everyone, I'm seeking assistance and visibility on a critical issue affecting .NET MAUI developers implementing subscriptions or in-app purchases on Android. Google Play Console now mandates that all new apps and updates to existing apps must use version 7.0.0 or later of the Google Play Billing Library. The deadline for this compliance is August 31, 2025. My application," previously used Plugin.InAppBilling for subscriptions. Unfortunately, this plugin has been archived by its maintainer (James Montemagno) and will no longer receive updates. The official Microsoft alternative, the Xamarin.Android.Google.BillingClient NuGet package (currently at version 7.1.1.4), still appears that is only compatible with Xamarin.Android and do not work with .NET MAUI.. This means that even after migrating to Xamarin.Android.Google.BillingClient, the warning in Google Play Console persists, blocking app updates. Currently, the only workaround I've found to upload my app to Play Console is to temporarily remove all subscription functionality, which is not a sustainable long-term solution. This is a significant roadblock for the .NET MAUI ecosystem, as monetization is a core aspect for many applications. Is anyone else experiencing this issue? Are there any alternative solutions, known workarounds, or are there plans from the Microsoft/.NET MAUI team to update the Xamarin.Android.Google.BillingClient package to support Google Play Billing Library 7.0.0+ before the deadline? Any insights or assistance would be greatly appreciated. Best regards, Shmenkare |

I'm adding paid subscriptions to my app and so I think I'll be facing the same problem soon. |

You should have a warning in your play console account. |

Plugin.InAppBilling Is no longer being maintained but the source code is available. Clone the repo on GitHub and update the billing package to the 7.x version. That’s what I did. |

James M had already completed most of the work, and you can see what needs to be changed in his PR: jamesmontemagno/InAppBillingPlugin#635 |

This is not a solution, but an important read: jamesmontemagno/InAppBillingPlugin#676 |

I recommend you take the code into your application, just clone it locally and pull in the code from the androidbilling7 branch. I will create a new version off this branch as folks have tested it and re-archive after that. |

Just to be sure: does 9.1.0 use Google Play Billing Library 7? Because I updated to 9.1.0, but the warning still persists in the Google Play Store. (By the way, I really appreciate your work James and everybody here) |

Should yes, double check androidmanifest: https://github.com/jamesmontemagno/InAppBillingPlugin?tab=readme-ov-file#version-7-major-updates it should AUTO add this though in your bin/obj and such |

Thanks! I see that the warning in Google Play is now gone. I should have been more patient :-) |

Additionally to note Xamarin.Android.Google.BillingClient is what I use, it is .NET 8+ and uses billing library 7. You can use it directly just like i did, which is better IMHO |

But the package Xamarin.Android.Google.BillingClient appears to be not compatible with .net maui, only with android.xamarin classic |

It is only for Android. Maui is multi platform so you would access from the android folder. https://learn.microsoft.com/en-us/dotnet/maui/platform-integration/invoke-platform-code?view=net-maui-9.0 Via an interface exactly like I do |

The package is literally .NET 8 + there is no more xamarin just legacy package name. I use it in my library, look at my code |

Thank you @jamesmontemagno for the android v7 billing support (published and confirmed to resolve the new requirement). This will give me plenty of time to roll it into my own code for future releases. Really appreciate all the work you put into it over the years and understand the reasoning for archiving the project. |

First, thank you @jamesmontemagno for all the amazing work you have done on the billing library through the years 🙏 @jfversluis, from a long term perspective, I'm curious to understand if there are any plans to support a billing library in .NET MAUI or in the .NET MAUI Community Toolkit? Thank you. |
