ZegoExpressEngine Audio/Video ReactNative SDK is a react-native wrapper based on [ZegoExpressEngine](https://doc-en.zego.im/en/693.html) native Android / iOS SDK, providing live video and real-time audio/video services. It only needs 4 lines of code and can be easily accessed in 30 minutes.

## 1️⃣ Apply for ZEGO AppID

Log in to [ZEGO Official Website](https://www.zego.im) to register an account, select a scenario according to your actual business needs, and obtain AppID and App Sign for initializing the SDK.

## 2️⃣ Import `zego-express-engine-reactnative` (only support react-native >= 0.60)

In your project, you can type in:

`npm install zego-express-engine-reactnative --save`

or

`yarn add zego-express-engine-reactnative`

Next, In **iOS**, you should `cd` to `ios` folder, and execute this command:

`pod install`

Now, you can use `zego-express-engine-reactnative` module in your project by using javascript or typescript(recommended)

## 3️⃣ Add device permissions

### Android

Open the file `app/src/main/AndroidManifest.xml`, and add the following contents:

```xml
    <!-- Permissions required by the SDK -->
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
    <uses-permission android:name="android.permission.RECORD_AUDIO" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.CAMERA" />
    <uses-permission android:name="android.permission.BLUETOOTH" />
    <uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <!-- Permissions required by the App -->
    <uses-permission android:name="android.permission.READ_PHONE_STATE" />
    <uses-permission android:name="android.permission.WAKE_LOCK" />

    <uses-feature
        android:glEsVersion="0x00020000"
        android:required="true" />

    <uses-feature android:name="android.hardware.camera" />
    <uses-feature android:name="android.hardware.camera.autofocus" />
```

> Note: Because Android 6.0 requires dynamic permissions for some of the more important permissions, you cannot apply for static permissions only through the `AndroidMainfest.xml` file. Therefore, you need to refer to the following code

```javascript
import {PermissionsAndroid} from 'react-native';

const granted = PermissionsAndroid.check(PermissionsAndroid.PERMISSIONS.CAMERA,
                                        PermissionsAndroid.RECORD_AUDIO);
granted.then((data)=>{

        if(!data) {
            const permissions = [PermissionsAndroid.PERMISSIONS.RECORD_AUDIO, PermissionsAndroid.PERMISSIONS.CAMERA];
            PermissionsAndroid.requestMultiple(permissions);
        }
    }).catch((err)=>{
    console.log(err.toString());
    })
}
```

### iOS

Choose the option TARGETS -> Info -> Custom iOS Target Properties

![Add iOS Privacy](https://storage.zego.im/sdk-doc/Pics/iOS/ZegoExpressEngine/Common/privacy-description.png)

Click the + Add button to add camera and microphone permissions.

1. `Privacy - Camera Usage Description`

2. `Privacy - Microphone Usage Description`

After adding permissions, it will be as shown:

![Add iOS Privacy Done](https://storage.zego.im/sdk-doc/Pics/iOS/ZegoExpressEngine/Common/privacy-description-done.png)

## 4️⃣ Init SDK

```javascript
import React, { Component } from 'react';
import ZegoExpressEngine from 'zego-express-engine-reactnative';

export default class App extends Component<{}> {

    componentDidMount() {
        ZegoExpressEngine.createEngineWithProfile({appID: 1234567890, scenario: ZegoScenario.General}).then((engine) => {
            if(engine != undefined)
                console.log("init sdk success");
            else
                console.log("init sdk failed");
        });
    }
}
```
