2. Must have a Huawei phone with HMS 4.0.0.300 or later
3. React Native environment with Android Studio, Node Js and Visual Studio code.
Major Dependencies
1. React Native CLI : 2.0.1
2. Gradle Version: 6.0.1
3. Gradle Plugin Version: 3.5.2
4. React Native Account Kit SDK : 5.0.0.300
5. React-native-hms-account kit gradle dependency
6. AGCP gradle dependency
Preparation
1. Create an app or project in the Huawei app gallery connect, click My apps, as shown below.
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
1.0 Click on New app.
2. Provide the SHA Key and App Package name of the project in App Information Section and enable the required API.
2.0 Add the below information to create a new app and project
2.1 Once app is created, navigate to My projects
2.2 Click on the created project, as shown below.
2.3 Enable the AccountKit API
2.4 Put SHA signature generated using Android Studio
2.5 Download agconnect-services.json services file and paste it under App folder of the project.
3. Create a react native project, use the below command
Code:
“react-native init project name”
4. Download the React Native Account Kit SDK and paste it under Node Modules directory of React Native project.
Tips
1. Run below command under project directory using CLI if you cannot find node modules.
Code:
“npm install” & “npm link”
Integration
1. Configure android level build.gradle
Add to buildscript/repositories and allprojects/repositories
Code:
maven {url 'http://developer.huawei.com/repo/'}
2. Configure app level build.gradle. (Add to dependencies)
Code:
Implementation project (“:react-native-hms-account”)
3. Linking the HMS Account Kit Sdk.
Run below command in the project directory
Code:
react-native link react-native-hms-account
Adding permissions
Add below permissions to Android.manifest file.
Code:
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
Development Process
Once sdk is integrated and ready to use, add following code to your App.js file which will import the API’s present.
Import the SDK
Silent Sign In
On Cancel Authorization
On Adding Authorization Scopes
Retrieve SMS Verification Code
Testing
Import the SDK
Add below line of code in the app.js file
Code:
import RNHMSAccount from "react-native-hms-account";
Silent Sign In
With silent sign in, the users can sign in without using their login credientials for consecutive sign-ins. To silent sign in, invoke the silentSignIn method of the HMSAccount module. The promise is resolved if the silent sign in is successful, is rejected otherwise.
Add below code on the “SILENT SIGN IN” button click
Code:
const onSilentSignIn = () => {
RNHMSAccount.HmsAccount.silentSignIn()
.then((response) => {
logger(JSON.stringify(response));
})
.catch((err) => {
logger(err);
});
};
On Cancel Authorization
Cancelling authorization is intended to increase security by forcing the users to use login credentials while signing in. To cancel authorization, invoke the cancel Authorization method of the HMSAccount module. The promise is resolved if the silent sign in is successful, is rejected otherwise.
Add below code on the “ONCANCELAUTHORIZATION” button click.
Code:
const onCancelAuthorization = () => {
RNHMSAccount.HmsAccount.cancelAuthorization()
.then((response) => {
logger(JSON.stringify(response));
})
.catch((err) => {
logger(err);
});
};
On Adding Authorization Scopes
Auth Manager class is responsible for creating the authorization scopes to build the data.
Add below code on the “ONADDAUTHSCOPES” button click.
Code:
const onAddAuthScopes = () => {
let buildData = {
requestCode: 888,
scopes: [RNHMSAccount.HmsAccount.SCOPE_ID_TOKEN],
};
RNHMSAccount.HuaweiIdAuthManager.addAuthScopes(buildData)
.then((response) => {
logger(JSON.stringify(response));
})
.catch((err) => {
logger(err);
});
};
Retrieve SMS Verification Code
Read SMS manager is a service to listen verification code SMS events. To start read SMS manager, invoke the startReadSMSManager method of the module.
Code:
const onStartReadSMSManager = () => {
RNHMSAccount.SMSManager.startReadSMSManager()
.then((response) => {
logger(JSON.stringify(response));
})
.catch((err) => {
logger(err);
});
};
Testing
Run the below command to build the project
Code:
React-native run-android.
After successful build, run the below command in the android directory of the project to create the signed apk.
Code:
gradlew assembleRelease
