I'm implementing push notification in Huawei devices and I've got this exception while trying to get token. And this this because of this line:

    Client = HmsInstanceId.GetInstance(Application.Context);

Exception:

{Java.Lang.NoClassDefFoundError: Failed resolution of: Lcom/huawei/hms/framework/common/EmuiUtil; ---> Java.Lang.ClassNotFoundException: Didn't find class "com.huawei.hms.framework.common.EmuiUtil" on path: DexPathList[[zip file....

The exception message :

failed resolution of: Lcom/huawei/hms/framework/common/EmuiUtil

How can I solve it?

  • hi@Yasmine Abdelsamie, Could you kindly help us with some information to locate this issue? 1. what SDK version are you integrated with? 2. Have you configured obfuscation scripts? And also it would be nice if you could provide your test apk for us to test, you can send it to hmscore@huawei.com. – zhangxaochen Dec 30 '21 at 10:04

According to this solution on GitHub, installing the NuGet package Huawei.Hms.NetworkFrameworkCompat will fix the issue. The install should be done for the Android Project.
