Expert: Xamarin Android Weather App highlights Weather Awareness API and Login with Huawei Id
HMS Account Kit allows you to connect to the Huawei ecosystem using your HUAWEI ID from a range of devices, such as mobile phones, tablets, and smart screens.
Overview
In this article, I will create a demo app along with the integration of HMS Account & Awareness Kit which is based on Cross platform Technology Xamarin. User can easily login with Huawei Id and get the details of their city weather information. I have implemented Huawei Id for login and Weather Awareness for weather forecasting.
Account Kit Service Introduction
HMS Account Kit allows you to connect to the Huawei ecosystem using your HUAWEI ID from a range of devices, such as mobile phones, tablets, and smart screens.
It’s a simple, secure, and quick sign-in and authorization functions. Instead of entering accounts and passwords and waiting for authentication.
Complies with international standards and protocols such as OAuth2.0 and OpenID Connect, and supports two-factor authentication (password authentication and mobile number authentication) to ensure high security.
Weather Awareness Service Introduction
HMS Weather Awareness Kit allows your app with the ability to obtain contextual information including users’ current time, location, behavior, audio device status, ambient light, weather, and nearby beacons. Your app can gain insight into a user’s current situation more efficiently, making it possible to deliver a smarter, more considerate user experience.

Account Kit Integration
Development Procedure
1. Call the HuaweiIdAuthParamsHelper.SetAuthorizationCode method to send an authorization request.
2. Call the GetService method of HuaweiIdAuthManager to initialize the IHuaweiIdAuthService object.
IHuaweiIdAuthService mAuthManager;
mAuthManager = HuaweiIdAuthManager.GetService(this, mAuthParam);
3. Call the IHuaweiIdAuthService.SignInIntent method to bring up the HUAWEI ID authorization & sign-in screen.
StartActivityForResult(mAuthManager.SignInIntent, 8888);
4. Process the result after the authorization & sign-in is complete.
LoginActivity.cs
This activity perform all the operation regarding login with Huawei Id.
Weather Awareness API Integration
Assigning Permissions in the Manifest File
Before calling the weather awareness capability, assign required permissions in the manifest file.
<!-- Location permission. This permission is sensitive and needs to be dynamically applied for in the code after being declared. -->
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
Developing Capabilities
Call the weather capability API through the Capture Client object.
MainActivity.cs
This activity perform all the operation regarding Weather Awareness api like current city weather and other information.
Xamarin App Build Result
1. Navigate to Solution Explore > Project > Right Click > Archive/View Archive to generate SHA-256 for build release and Click on Distribute.
2. Choose Distribution Channel > Ad Hoc to sign apk.
3. Choose Demo keystore to release apk.
4. Build succeed and Save apk file.
5. Finally here is the result.
Tips and Tricks
1. Awareness Kit supports wearable Android devices, but HUAWEI HMS Core 4.0 is not deployed on devices other than mobile phones. Therefore, wearable devices are not supported currently.
2. Cloud capabilities are required to sense time information and weather.
3. 10012: HMS Core does not have the behaviour recognition permission.
Conclusion
In this article, we have learned how to integrate HMS Weather Awareness and Account Kit in Xamarin based Android application. User can easily login and check weather forecast.
