Creating a Project in AppGallery Connect

Creating an app in AppGallery Connect is required in order to communicate with the Huawei services. To create an app, perform the following steps:

Step 1. Sign in to AppGallery Connect and select My projects.

Step 2. Select your project from the project list or create a new one by clicking the Add Project button.

Step 3. Go to Project Setting > General information, and click Add app. If an app exists in the project and you need to add a new one, expand the app selection area on the top of the page and click Add app.

Step 4. On the Add app page, enter the app information, and click OK.

• A signing certificate fingerprint is used to verify the authenticity of an app when it attempts to access an HMS Core service through the HMS Core SDK. Before using HMS Core (APK), you must locally generate a signing certificate fingerprint and configure it in AppGallery Connect. Ensure that the JDK has been installed on your computer.

Configuring the Signing Certificate Fingerprint

Step 1. Go to Project Setting > General information. In the App information field, click the icon next to SHA-256 certificate fingerprint, and enter the obtained SHA256 certificate fingerprint.

Step 2. After completing the configuration, click check mark.

React-Native Integration

Step 1: Sign in to AppGallery Connect and select My projects.

Step 2: Find your app project, and click the desired app name.

Step 3: Go to Project Setting > General information. In the App information section, click agconnect-service.json to download the configuration file.

Step 4: Create a React Native project if you do not have one.

Step 5: Copy the agconnect-service.json file to the android/app directory of your React Native project.

Step 6: Copy the signature file that generated in Generating a Signing Certificate section, to the android/app directory of your React Native project.

Step 7: Check whether the agconnect-services.json file and signature file are successfully added to the android/app directory of the React Native project.

Step 8: Open the AndroidManifest.xml file, add the following lines, and replace the value <app_id> with the value you found in the agconnect-services.json file.

<application>
...
     <meta-data
            android:name="com.huawei.hms.client.appid"
            android:value="appid=<app_id>" />
</application>

Step 9: Open the build.gradle file in the android directory of your React Native project.

• Go to buildscript then configure the Maven repository address and agconnect plugin for the HMS SDK.

buildscript {    
  repositories {        
    google()        
    jcenter()        
    maven { url 'https://developer.huawei.com/repo/' }   
  }    

  dependencies {        
    /*          
      * <Other dependencies>        
      */   
    classpath 'com.huawei.agconnect:agcp:1.4.1.300'    
  }
}

• Go to allprojects then configure the Maven repository address for the HMS SDK.

allprojects {
  repositories {
    /*          
      * <Other repositories>        
      */  
    maven { url 'https://developer.huawei.com/repo/' }
  }
}

Step 10: Open the build.gradle file in the android/app directory of your React Native project.

• Package name must match with the package_name entry in agconnect-services.json file.

defaultConfig {
  applicationId "<package_name>"
  minSdkVersion 21
  /*
   * <Other configurations>
   */
}

android {
  /*
   * <Other configurations>
   */

  signingConfigs {
    config {
      storeFile file('<keystore_file>.jks')
      storePassword '<keystore_password>'
      keyAlias '<key_alias>'
      keyPassword '<key_password>'
    }
  }

  buildTypes {
    debug {
      signingConfig signingConfigs.config
    }
    release {
      signingConfig signingConfigs.config
      minifyEnabled enableProguardInReleaseBuilds
      ...
    }
  }
}

Step 11: Open the build.gradle file in the android/app directory of your React Native project.

• Configure build dependencies.

buildscript {
  ...
  dependencies {
    /*
    * <Other dependencies>
    */
    implementation ('com.huawei.hms:rn-adapter:5.1.0.300'){
        exclude group: 'com.facebook.react'
    } 
    ...    
  }
}

Step 12: Import the following class to the MainApplication.java file of your project.

import com.huawei.hms.jsb.adapter.rn.RnJSBReactPackage;

Then, add the RnJSBReactPackage() to your getPackages method. In the end, your file will be similar to the following:

@Override
protected List<ReactPackage> getPackages() {
    List<ReactPackage> packages = new PackageList(this).getPackages();
    packages.add(new RnJSBReactPackage()); // <-- Add this line 
    return packages;
}
...

Step 13: Download js-sdk using command below.

npm i @hmscore/hms-js-contactshield

Step 14: Import HMSContactShield in App.js as following line.

import HMSContactShield from "@hmscore/hms-js-contactshield";

Step 15: Run your project.

• Run the following command to the project directory.

react-native run-android  

Cordova Integration

  ...
  
  import com.huawei.hms.jsb.adapter.cordova.CordovaJSBInit;
  
  public class MainActivity extends CordovaActivity
  {
      @Override
      public void onCreate(Bundle savedInstanceState)
      {
          super.onCreate(savedInstanceState);
          CordovaJSBInit.initJSBFramework(this);
  
          ...
      }
      ...
  }

Step 10: Open the AndroidManifest.xml file, add the following lines, and replace the value <app_id> with the app_id value that can be found in the agconnect-services.json file.

4. Configuration and Description

Configuring Obfuscation Scripts

React Native

In order to prevent error while release build, you may need to add following lines in proguard-rules.pro file.

-ignorewarnings
-keepattributes *Annotation*
-keepattributes Exceptions
-keepattributes InnerClasses
-keepattributes Signature
-keep class com.hianalytics.android.**{*;}
-keep class com.huawei.updatesdk.**{*;}
-keep class com.huawei.hms.**{*;}
-repackageclasses

Cordova

Before building the APK, configure the obfuscation configuration file to prevent the HMS Core SDK from being obfuscated.

NOTE: This step is required only if you want to minify and obfuscate your app. By default obfuscation is disabled in Cordova and Ionic apps.

The obfuscation is done by ProGuard. By default, in Cordova and Ionic apps ProGuard is disabled. Even though ProGuard is not available, ProGuard support can be added through 3rd party ProGuard plugins. If ProGuard is enabled in your project, the Huawei Cordova Contact Shield plugin's ProGuard rules need to be added to your project. These rules are as follows:

-ignorewarnings
-keepattributes *Annotation*
-keepattributes Exceptions
-keepattributes InnerClasses
-keepattributes Signature
-keep class com.huawei.hianalytics.**{*;}
-keep class com.huawei.updatesdk.**{*;}
-keep class com.huawei.hms.**{*;}
-repackageclasses

5. Questions or Issues

If you have questions about how to use HMS samples, try the following options:

• Stack Overflow is the best place for any programming questions. Be sure to tag your question with huawei-mobile-services.
• Huawei Developer Forum HMS Core Module is great for general questions, or seeking recommendations and opinions.
• Huawei Developer Docs is place to official documentation for all HMS Core Kits, you can find detailed documentations in there.
