2. Provide the SHA Key and App Package name of the project in App Information Section and enable the App Messaging API.
3. Download the agconnect-services.json file.
4. Create an Android project.
Integration process
Create a react native project using below command:
Code:
react-native init Project Name
Add below to build.gradle (project) file under buildscript/repositories and allprojects/repositories.
Code:
Maven {url 'http://developer.huawei.com/repo/'}
Add below to build.gradle(app) file, under dependencies to use the App Messaging Sdk.
dependencies{
// Import the App Messaging SDK.
Code:
implementation 'com.huawei.agconnect:agconnect-appmessaging:1.5.1.300'
Note>> to use the Analytics, please add Analytics SDK
Code:
implementation 'com.huawei.hms:hianalytics:5.2.0.300'
}
Add below permissions to manifest file.
Code:
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name= "android.permission.ACCESS_NETWORK_STATE"/>
Open the build.gradle file in the android directory of your React Native project, and change the value of minSdkVersion in buildscript to 19.
Development Process
To make your app's orientation work by default, orientation keywords should be removed from android:configChanges property of the activity tag in AndroidManifest.xml file.
An example of your AndroidManifest.xml is as follows:
Code:
<!-- AndroidManifest.xml. -->
<activity
android:name="com.huawei.agc.rn.appmessaging.example.MainActivity"
android:label="@string/app_name"
android:configChanges="keyboard|keyboardHidden|screenSize|uiMode"
android:launchMode="singleTask"
android:windowSoftInputMode="adjustResize">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
Import the following into APP.js file.
Code:
import AGCAppMessaging from '@react-native agconnect/appmessaging';
import {Alert} from 'react-native';
The React Native App Messaging plugin allows you to enable or disable data synchronization from the AppGallery Connect server. The function is enabled by default. The AGCAppMessaging.setFetchMessageEnable API can be called to enable or disable data synchronization from the AppGallery Connect server.
Code:
import AGCAppMessaging from '@react-native-agconnect/appmessaging';
import {Alert} from 'react-native';
AGCAppMessaging.setFetchMessageEnable(true).then(result => {
Alert.alert("[setFetchMessageEnable] " + JSON.stringify(result));
}).catch((err) => {
Alert.alert("[setFetchMessageEnable] Error/Exception: " + JSON.stringify(err));
});
The AGCAppMessaging.setDisplayEnable API can be called to set whether to enable message display.
Code:
import AGCAppMessaging from '@react-native-agconnect/appmessaging';
import {Alert} from 'react-native';
AGCAppMessaging.setDisplayEnable(false).then(result => {
Alert.alert("[setDisplayEnable] " + JSON.stringify(result));
}).catch((err) => {
Alert.alert("[setDisplayEnable] Error/Exception: " + JSON.stringify(err));
});
Add a listener to obtain app message events.
Code:
const eventEmitter = new NativeEventEmitter(AGCAppMessaging);
this.eventListener = eventEmitter.addListener(AGCAppMessaging.EventTypes.ON_MESSAGE_DISPLAY,
(event) => {
Alert.alert("[onMessageDisplay] " + JSON.stringify(event));
console.log("[onMessageDisplay] " + JSON.stringify(event));
})
Call the AGCAppMessaging.setForceFetch API in the testing code to specify that the in-app message data must be obtained from the AppGallery Connect server forcibly.
