Is Huawei HMS tolerated on Google Play Store?

3.2k views Asked by At

I have an app with the usual Google ad and in-app-payment stuff. It's accepted into the Play Store all right. Now I'd like to make it support both GMS and HMS at the same time (based on the availability of the appropriate services, the app can decide which platform to use). The app, with the Huawei functionality built in, works just fine while testing on my own devices.

However, as soon as Huawei's libraries are bundled with the app, the Play Store Console simply refuses it. No error message, just a red exclamation point. There's no doubt about the situation, I started to remove the Huawei-related parts one by one and as soon as the last bit was removed, the bundle was automagically accepted again.

Yes, sure, I might have made some error I'm not aware of but the situation is, well, rather suspicious. If it makes any difference, I use Flutter and I try to upload an app bundle, not APKs, as per normal these days. The HMS library that seems to make it or break it is com.huawei.hms:hwid:4.0.0.300 from the maven repo at https://developer.huawei.com/repo/.

So, am I just seeing things or not?

Update:

OK, the quest goes on.

This is quite recent news: https://support.google.com/googleplay/android-developer/answer/9934569

Any existing app that is currently using an alternative billing system will need to remove it to comply with this update. For those apps, we are offering an extended grace period until September 30, 2021 to make any required changes. New apps submitted after January 20, 2021 will need to be in compliance.

No matter what the policy says, the Play Console seems to enforce it already. And as I found by looking into the app bundle, the flavor approach is just not enough. Even with the other flavor, there will remain some packages referenced by Flutter. Maybe just the referenced names, not the actual code after tree shaking, but this is already enough for the refusal.

So, at the end of the day, I really think this question needs to be sorted out and some clear guidelines found for and by ourselves, developers, if we really want to write cross-ecosystem, single source Flutter apps. As for me, I sure want to do it.

I have finally found a kind of a workaround, not automatic, but a useable approach.

Create two subpackages inside your project. They look like normal Flutter packages but reside inside your app. Basically, create two folders, gms_support and hms_support beside your usual lib. Both are packages with the usual structure:

  • lib
  • lib\Xms_support.dart
  • lib\src
  • lib\pubspec.yaml

Put all your vendor-dependent stuff into identically structured files inside the respective lib\src folders and make sure both XXX_support.dart files export them the usual way. The implementations should use the same classes and same signatures. Each pubspec.yaml refers to its own, vendor-specific Flutter plugins required for their implementation.

Your main app pubspec.yaml contains both references:

dependencies:
  ...
  gms_support:
    path: gms_support/
  hms_support:
    path: hms_support/

Also, add another support.dart inside your main app:

export 'package:gms_support/gms_support.dart';
export 'package:hms_support/hms_support.dart';

Wherever you need vendor-specific behavior in your app, you import and use this support.dart file.

Then, when you have to change from one flavor to another, you always have to change three things in sync:

  • the flavor (see the details of your IDE)
  • comment out the other export in support.dart
  • comment out the other reference in pubspec.yaml and make a pub update

Different App store has different requirements for In-App Purchase Kit. The possible cause for the Play Store Console refusing your app is that your app integrated with other IAP Kit, and it does not meet the requirements of the app store review guide. You are advised to make your project support different app packages for different channels, to adapt different app store requirements.

Supporting Multiple Flavors

If your app needs to support multiple build types or flavors, configure the agconnect-services.json configuration file downloaded from AppGallery Connect for your app to implement the function. The agconnect-services.json file provides configuration information required by various services in your AppGalleryConnect project. Therefore, if you need to use multiple flavors to release different app versions, copy the agconnect-services.json file to the folder of each flavor and configure it.

Supporting Multiple Channels

If your project needs to support different app packages for different channels, the package name needs to vary depending on the channel. Change the package name in productFlavor in the build.gradle file under the app directory.

productFlavors { 
    huawei{ 
        // Unique package name. 
        applicationId "com.example.demo.huawei" 
        resValue "string", "app_name", "Huawei" 
    } 
    amazon{ 
        applicationId "com.example.demo.amazon" 
        resValue "string", "app_name", "Amazon" 
    } 
}

The preceding sample code shows different packaging configurations for different channels, Huawei and Amazon. The package names are different for the two channels. If the same agconnect-services.json file is used for the two channels, the package name verification fails. To support multiple channels, you need to add the agconnect-services.json file to the flavor folder of only the Huawei channel and ensure that the AppGallery Connect plug-in version in the project is 1.2.1.301 or later classpath'com.huawei.agconnect:agcp:1.2.1.301'). If the plug-in version is earlier than 1.2.1.301, upgrade it to 1.2.1.301 or later.
