React Native Module for **Floating/Popup** video player on Android. From android 8.0 Oreo onwards we have `PictureInPicture` mode built into android which is great but even today there are many devices below android 8.0 and hence there is a need for some alternative. This library helps you with that issue if you are making a video application with floating video support starting from android 4.4.2 kitkat.

## Run the Example
To run the example app clone the project

git clone https://github.com/ammarahm-ed/rn-floating-video-widget.git

then run ` yarn or npm install` in the example folder and finally to run the example app:
       
   
    react-native run-android

## Installation

npm install rn-floating-video-widget --save
or if you use yarn:

yarn add rn-floating-video-widget

If you are using `react-native <= 0.59.0` you also need to run:

react-native link rn-floating-video-widget

Add permission `SYSTEM_ALERT_WINDOW` to `AndroidManifest.xml`:

```xml
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>
```

Add the following `service` in `AndroidManifest.xml` inside `<application>` tag:

```xml
<application>
    ...
    <service android:name="com.rnfloatingvideowidget.FloatingVideoWidgetShowService"  
    android:enabled="true"></service>
    ...
</application>
```
 
## Usage
For complete usage, see the example project.

```jsx
import React from "react";
import {
  StyleSheet,
  View,
  TouchableOpacity,
  ToastAndroid,
  Text
} from "react-native";
import FloatingVideo from "rn-floating-video-widget";

export default class App extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      floating: false,
      granted: false
    };
    // The Data Object
    this.data = {
      video: {
        url:
          "http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4"
      },
      videos: [
        {
          url:
            "http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4"
        },
        {
          url:
            "http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/ElephantsDream.mp4"
        },
        {
          url:
            "http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/ForBiggerBlazes.mp4"
        }
      ],
      seek: 10,
      index: 0
    };
  }

componentDidMount() {
    // Add event listeners

FloatingVideo.onClose(data => console.log(data));
    FloatingVideo.onOpen(data => console.log(data));
    FloatingVideo.onPlay(data => console.log(data));
    FloatingVideo.onPause(data => console.log(data));
    FloatingVideo.onNext(data => console.log(data));
    FloatingVideo.onPrev(data => console.log(data));
    FloatingVideo.onError(data => console.log(data));
  }

enterPipMode() {
    FloatingVideo.requestOverlayPermission()
      .then(() => {
        this.setState({
          floating: true,
          granted: true
        });
        FloatingVideo.open(this.data);
      })
      .catch(e => {
        ToastAndroid.show(
          "Please grant draw over other apps permission" + JSON.stringify(e),
          800
        );
      });
  }

componentWillUnmount() {
    FloatingVideo.removeAllListeners();
  }

render() {
    const floating = this.state.floating;

return (
      <View style={styles.container}>
        <TouchableOpacity
          style={styles.start}
          onPress={() => {
            this.enterPipMode();
          }}
        >
          <Text
            style={{
              color: "white",
              fontSize: 20
            }}
          >
            START
          </Text>
        </TouchableOpacity>
      </View>
    );
  }
}

const styles = StyleSheet.create({
  container: {
    flex: 1,

alignItems: "center",
    paddingTop: 20,
    backgroundColor: "#F5FCFF"
  },
  welcome: {
    fontSize: 20,
    textAlign: "center",
    margin: 10
  },
  start: {
    width: "90%",
    alignSelf: "center",
    padding: 15,
    backgroundColor: "red",
    justifyContent: "center",
    alignItems: "center",
    elevation: 5,
    borderRadius: 5
  },
  button: {
    alignSelf: "center",
    padding: 5,
    borderWidth: 1,
    borderColor: "red",
    backgroundColor: "white",
    justifyContent: "center",
    alignItems: "center",
    elevation: 5,
    borderRadius: 5
  }
});
```

## FloatingVideo API
FloatingVideo API has been kept very simple and practical in use.
### Methods
|Name|Arguments|Description|
|--|--|--|
|open|Data `object` (see below)|Initialise the player and play video
|play ||Play/Resume the video
|pause||Pause the video
|next||Play the next video in playlist
|prev||Play the previous video in playlist
|close||Close the Foating Video Player
|requestOverlayPermission||Ask for `draw over other apps` permission

#### `Data Object`
The video data object is a single object that can have the following properties

### Event Listeners
All event listeners should have a callback function as an argument to handle the event.

|Name|Description|Data recieved from event|
|--|--|--|
| onOpen |Floating video is open and video is playing | `{type:"open",seek,index,url}`
| onPlay |Video started playing | `{type:"play",seek,index,url}`
| onPause|Video was paused| `{type:"pause",seek,index,url}` 
|onNext|Next video started playing| `{type:"next",seek,index,url}`
|onPrev|Previous video started playing| `{type:"prev",seek,index,url}`
|onClose|Floating Video Player was closed| `{type:"close",seek,index,url}`
|onError|An error occurred| `{type:"error",seek,index,url}`

Don't forget to call `FloatingVideo.removeAllListeners()` when component unmount.

## Todo List
 - [ ] Improve native code quality
 - [ ] Complete error handling
 - [ ] Use ExoPlayer w/o ExoMedia Library
