### API End Points Supported

1. To Get Access Token Endpoint : => https://docs.v-empower.com/docs/MeetHour-API/a44a7d7669f91-user-login-get-access-token

   ```
       ApiServices.login({

## Usage

In this SDK, you can make APIs calls and allow join the conference in Native View or React Native View.

```
import MeetHour, {MeetHourView, ApiServices} from 'react-native-meet-hour-sdk';
import React, {useState, useEffect} from 'react';
import {
  StyleSheet,
  View,
  Pressable,
  Text,
  Platform,
  Alert
} from 'react-native';

const loginBody = {
  client_id: '',
  client_secret: '',
  username: '',
  password: '',
};

const ScheduleBody = {
  meeting_name: 'Quick Meeting',
  agenda: '',
  passcode: '123456',
  meeting_date: '23-02-2025', // Make sure you give a future date for this parameter
  meeting_time: '11:30',
  meeting_meridiem: 'AM',
  timezone: 'Asia/Kolkata',
  instructions: 'Team call',
  is_show_portal: 0,
  options: ['ALLOW_GUEST', 'JOIN_ANYTIME'],
  // attend: [] // Pass the values as per documentation.
  // hostusers: []
};

let getJWTBody = {
  meeting_id: '',
};

const conferenceOptions = {
  room: '',
  token: '', // JWT Token
  pcode: '', //Dynamic Password of Conference. Will get from Schedule API & ViewMeeting APIs
  audioMuted: false,
  videoMuted: false,
  prejoinPageEnabled: true, // Make it false to Skip PrejoinPage
  disableInviteFunctions: true, // To disable invite functions in Mobile SDK.
};

function App() {
  const [showMeetHourView, setShowMeetHourView] = useState(false);

      Note:
        MeetHour.launchMeetHourView will return a promise, which is resolved once the conference is terminated and the MeetHourView is dismissed.

See [Options](#options) for further information.

## iOS install

1.) This library uses Swift code, so make sure that you have created the `Objective-C bridging header file`.

If not, open your project in Xcode and create an empty Swift file.

Xcode will ask if you wish to create the bridging header file, please choose yes.

For more information check [Create Objective-C bridging header file](https://developer.apple.com/documentation/swift/imported_c_and_objective-c_apis/importing_objective-c_into_swift).

2.) Replace the following code in AppDelegate.m (ONLY required for mode 1. If you're using mode 2, skip this step):

```objective-c
UIViewController *rootViewController = [UIViewController new];
rootViewController.view = rootView;
self.window.rootViewController = rootViewController;
```

with this one

```objective-c
UIViewController *rootViewController = [UIViewController new];
UINavigationController *navigationController = [[UINavigationController alloc]initWithRootViewController:rootViewController];
navigationController.navigationBarHidden = YES;
rootViewController.view = rootView;
self.window.rootViewController = navigationController;
```

This will create a navigation controller to be able to navigate between the MeetHour component and your react native screens.

3.) Add the following lines to your `Info.plist`

```xml
<key>NSCameraUsageDescription</key>
<string>Camera Permission</string>
<key>NSMicrophoneUsageDescription</key>
<string>Microphone Permission</string>
<key>NSCalendarUsageDescription</key>
<string>Calendar Permission</string>
```

4.) Modify your platform version in Podfile and Xcode to have platform version `12.0` or above.

5.) In Xcode, under `Build settings` set `Enable Bitcode` to `No` and `Always Embed Swift Standard Libraries` to `Yes`.

6.) In Xcode, under `Signing & Capabilities` add the capability `Background Modes` and check `Voice over IP`. Otherwise, it won't work well in background.

7.) Clean your project and run `npx pod-install`.

## Android install

1.) In `android/app/build.gradle`, add/replace the following lines:

```groovy
project.ext.react = [
    entryFile: "index.js",
    bundleAssetName: "app.bundle",
    ...
]
```

2.) In `android/app/src/main/java/com/xxx/MainApplication.java` add/replace the following methods:

```java
  import androidx.annotation.Nullable; // <--- Add this line if not already existing
  ...
    @Override
    protected String getJSMainModuleName() {
      return "index";
    }

    @Override
    protected @Nullable String getBundleAssetName() {
      return "app.bundle";
    }
```

3.) In `android/build.gradle`, add the following code

```groovy
allprojects {
    repositories {
        jcenter()
        maven {
            // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
            url "$rootDir/../node_modules/react-native/android"
        }
        maven {
            url "https://maven.google.com"
        }
        maven { // <---- Add this block
            url "https://repo.meethour.io/maven/releases/"
        }
    }
}
```

4.) In the `<application>` section of `android/app/src/main/AndroidManifest.xml`, add (ONLY required for mode 1. If you're using mode 2, skip this step)

```xml
<activity
    android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|screenSize|smallestScreenSize"
    android:launchMode="singleTask"
    android:resizeableActivity="true"
    android:supportsPictureInPicture="true"
    android:windowSoftInputMode="adjustResize"
    android:name="go.meethour.io.react.sdk.MeetHourActivityExtended">
</activity>
```

5.) And set your minSdkVersion to be at least 24.

```groovy
buildscript {
    ext {
        buildToolsVersion = "33.0.1"
        minSdkVersion = 24 // <-- this line
        compileSdkVersion = 33
        targetSdkVersion = 33
        ndkVersion = "20.1.5948944"
    }
    ...
}
```

6.) Remove allow back up from Androidmanifest.xml

```xml
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
  package="com.sdktest">

    <uses-permission android:name="android.permission.INTERNET" />

    <application
      android:name=".MainApplication"
      android:label="@string/app_name"
      android:icon="@mipmap/ic_launcher"
      android:roundIcon="@mipmap/ic_launcher_round"
      android:allowBackup="false" <-- this line
      android:theme="@style/AppTheme">
      <activity
        android:name=".MainActivity"
        android:label="@string/app_name"
        android:configChanges="keyboard|keyboardHidden|orientation|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>
    </application>
</manifest>
```

## Troubleshooting

If your having problems with `duplicate_classes` errors, try exclude them from the react-native-meet-hour-sdk project implementation with the following code:

```groovy
implementation(project(':react-native-meet-hour-sdk')) {
  
      // Un-comment below if using hermes
//    exclude group: 'com.facebook',module:'hermes'

      // Un-comment any packages below that you have added to your project to prevent `duplicate_classes` errors
//     exclude group: 'com.facebook.react',module:'react-native-locale-detector'
//     exclude group: 'com.facebook.react',module:'react-native-vector-icons'
//     exclude group: 'com.facebook.react',module:'react-native-async-storage'
//     exclude group: 'com.facebook.react',module:'react-native-community_netinfo'
//     exclude group: 'com.facebook.react',module:'react-native-svg'
//     exclude group: 'com.facebook.react', module:'react-native-gesture-handler'
//     exclude group: 'com.facebook.react',module:'react-native-fetch-blob'
//     exclude group: 'com.facebook.react',module:'react-native-webview'
//     exclude group: 'com.facebook.react',module:'react-native-linear-gradient'
//     exclude group: 'com.facebook.react',module:'react-native-sound'
//     exclude group: 'com.facebook.react',module:'react-native-add-calendar-event'
}
```


If you are having problems -> Suggestion: add 'tools:replace="android:exported"' to <provider> element at AndroidManifest.xml to override.

Please add the below code in manifest.xml

```
    <provider
        android:name="com.reactnativecommunity.webview.RNCWebViewFileProvider"
        android:authorities="${applicationId}.fileprovider"
        android:enabled="false"
        android:exported="true"
        tools:replace="android:authorities,android:exported">
    </provider>
```
