TODO: Write a proper readme.

Thanks to the following repos to provide ideas and insight about how to do this. https://github.com/voximplant/react-native-foreground-service https://github.com/zo0r/react-native-push-notification/

Installation

- Add to package.json
"react-native-foreground-service": "github:cristianoccazinsp/react-native-foreground-service",

-- For react native >= 60.0 , autolinking is used  

-- For react native previous versions 

react-native link react-native-foreground-service

Add/configure the following into the AndroidManifest.xml

```
<uses-permission android:name="android.permission.FOREGROUND_SERVICE"/>
<uses-permission android:name="android.permission.WAKE_LOCK" />


add a color.xml file in /android/app/src/main/res/values
```
<?xml version="1.0" encoding="utf-8"?>
<resources>
<item  name="orange"  type="color">#FF4500
</item>
<integer-array  name="androidcolors">
<item>@color/orange</item>
</integer-array>
</resources>
```

<!-- inside application -->

<meta-data android:name="com.zinspector.foregroundservice.notification_channel_name"
            android:value="zInspector Service"/>
<meta-data  android:name="com.zinspector.foregroundservice.notification_channel_description"
            android:value="zInspector Service."/>
<meta-data  android:name="com.zinspector.foregroundservice.notification_color"
            android:resource="@color/orange"/>

<service android:name="com.zinspector.foregroundservice.ForegroundService"></service>
<service android:name="com.zinspector.foregroundservice.ForegroundServiceTask"></service>
```

Usage:

TODO, but basically: register headless task (at module level) and then call the methods from index.js with the notification config

```
import ForegroundService from 'react-native-foreground-service';


// register task with a given name and function
let foregroundTask = async (data) => {
    await myTask();
}
ForegroundService.registerForegroundTask("myTaskName", foregroundTask);


// then later, start service, and send tasks

let notificationConfig = {
    id: 3,
    title: 'Service',
    message: `blah message`,
    visibility: 'public',
    importance: 'low',
    number: String(1)
};

await ForegroundService.startService(notificationConfig);

await ForegroundService.runTask({
  taskName: 'myTaskName',
  delay: 0
});


// stop service when no longer needed
await ForegroundService.stopServiceAll();
// or await ForegroundService.stopService();


```
