## 1. Introduction

## 2. Installation Guide

### 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](https://developer.huawei.com/consumer/en/service/josp/agc/index.html)  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](https://developer.huawei.com/consumer/en/service/josp/agc/index.html) 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](https://developer.huawei.com/consumer/en/codelab/HMSPreparation/index.html#3) 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.

```xml
<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.

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

  dependencies {        
    /*          
      * <Other dependencies>        
      */   
    classpath 'com.huawei.agconnect:agcp:1.4.2.301'    
  }
}
```

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

```groovy
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.

```groovy
defaultConfig {
  applicationId "<package_name>"
  minSdkVersion 19
  /*
   * <Other configurations>
   */
}
```

```groovy
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.

```groovy
buildscript {
  ...
  dependencies {
    /*
    * <Other dependencies>
    */
    implementation ('com.huawei.hms:rn-adapter:5.2.0.300'){
        exclude group: 'com.facebook.react'
    } 
    ...    
  }
}
```

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

```java
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:

```java
@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.

```bash
npm i @hmscore/hms-js-iap
```

**Step 14:** Import **HMSIAP** in App.js as following line.

```js
import HMSIAP from "@hmscore/hms-js-iap";
```

**Step 15:** Call HMSIAP's init method to initialize. 

```js
import { NativeModules, DeviceEventEmitter } from "react-native";
...

HMSIAP.init(NativeModules, DeviceEventEmitter);

## 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.

```text
-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 IAP plugin's ProGuard rules need to be added to your project. These rules are as follows:

```text
-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
```
