Thank you for your support!

## Installation
See npm package for versions - https://www.npmjs.com/package/cordova-plugin-firebase

Install the plugin by adding it your project's config.xml:
```
<plugin name="cordova-plugin-firebase" spec="0.1.24" />
```
or by running:
```
cordova plugin add cordova-plugin-firebase@0.1.24 --save
```
Download your Firebase configuration files, GoogleService-Info.plist for ios and google-services.json for android, and place them in the root folder of your cordova project:

```
- My Project/
    platforms/
    plugins/
    www/
    config.xml
    google-services.json       <--
    GoogleService-Info.plist   <--
    ...
```

See https://support.google.com/firebase/answer/7015592 for details how to download the files from firebase.

This plugin uses a hook (after prepare) that copies the configuration files to the right place, namely platforms/ios/\<My Project\>/Resources for ios and platforms/android for android.

**Note that the Firebase SDK requires the configuration files to be present and valid, otherwise your app will crash on boot or Firebase features won't work.**

## Changing Notification Icon
The plugin will use notification_icon from drawable resources if it exists, otherwise the default app icon will is used.
To set a big icon and small icon for notifications, define them through drawable nodes.  
Create the required styles.xml files and add the icons to the  
`<projectroot>/res/native/android/res/<drawable-DPI>` folders.  

The example below uses a png named "ic_silhouette.png", the app Icon (@mipmap/icon) and sets a base theme.  
From android version 21 (Lollipop) notifications were changed, needing a seperate setting.  
If you only target Lollipop and above, you don't need to setup both.  
Thankfully using the version dependant asset selections, we can make one build/apk supporting all target platforms.  
`<projectroot>/res/native/android/res/values/styles.xml`
```
<?xml version="1.0" encoding="utf-8" ?>
<resources>
    <!-- inherit from the holo theme -->
    <style name="AppTheme" parent="android:Theme.Light">
        <item name="android:windowDisablePreview">true</item>
    </style>
    <drawable name="notification_big">@mipmap/icon</drawable>
    <drawable name="notification_icon">@mipmap/icon</drawable>
</resources>
```
and  
`<projectroot>/res/native/android/res/values-v21/styles.xml`
```
<?xml version="1.0" encoding="utf-8" ?>
<resources>
    <!-- inherit from the material theme -->
    <style name="AppTheme" parent="android:Theme.Material">
        <item name="android:windowDisablePreview">true</item>
    </style>
    <drawable name="notification_big">@mipmap/icon</drawable>
    <drawable name="notification_icon">@drawable/ic_silhouette</drawable>
</resources>
```

## Notification Colors

On Android Lollipop and above you can also set the accent color for the notification by adding a color setting.

`<projectroot>/res/native/android/res/values/colors.xml`
```
<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="primary">#FFFFFF00</color>
    <color name="primary_dark">#FF220022</color>
    <color name="accent">#FF00FFFF</color>
</resources>
```


### Notes about PhoneGap Build

Hooks does not work with PhoneGap Build. This means you will have to manually make sure the configuration files are included. One way to do that is to make a private fork of this plugin and replace the placeholder config files (see src/ios and src/android) with your actual ones, as well as hard coding your app id and api key in plugin.xml.


## Methods

### getToken

Get the device token (id):
```
window.FirebasePlugin.getToken(function(token) {
    // save this server-side and use it to push notifications to this device
    console.log(token);
}, function(error) {
    console.error(error);
});
```
Note that token will be null if it has not been established yet

### onTokenRefresh

Register for token changes:
```
window.FirebasePlugin.onTokenRefresh(function(token) {
    // save this server-side and use it to push notifications to this device
    console.log(token);
}, function(error) {
    console.error(error);
});
```
This is the best way to get a valid token for the device as soon as the token is established

### onNotificationOpen

Register notification callback:
```
window.FirebasePlugin.onNotificationOpen(function(notification) {
    console.log(notification);
}, function(error) {
    console.error(error);
});
```
Notification flow:

1. App is in foreground:
    1. User receives the notification data in the JavaScript callback without any notification on the device itself (this is the normal behaviour of push notifications, it is up to you, the developer, to notify the user)
2. App is in background:
    1. User receives the notification message in its device notification bar
    2. User taps the notification and the app opens
    3. User receives the notification data in the JavaScript callback

### grantPermission (iOS only)

```
window.FirebasePlugin.grantPermission();
```
### hasPermission

Check permission to recieve push notifications:
```

    console.log(data.isEnabled);
});

```

### activateFetched

Activate the Remote Config fetched config:
```
window.FirebasePlugin.activateFetched(function(activated) {

    // or false if no fetched config was found, or the fetched config was already activated.
    console.log(activated);
}, function(error) {

}, function(error) {
    console.error(error);
});
```

### getByteArray (Android only)
**NOTE: byte array is only available for SDK 19+**
Retrieve a Remote Config byte array:
```
window.FirebasePlugin.getByteArray("key", function(bytes) {
    // a Base64 encoded string that represents the value for "key"
    console.log(bytes.base64);
    // a numeric array containing the values of the byte array (i.e. [0xFF, 0x00])
    console.log(bytes.array);

    console.log(info.configSettings.developerModeEnabled);
    // the timestamp (milliseconds since epoch) of the last successful fetch
    console.log(info.fetchTimeMillis);
    // the status of the most recent fetch attempt (int)
    console.log(info.lastFetchStatus);
}, function(error) {

    mDouble: 3.14,
    mBoolean: true,
    // map "mBase64" to a Remote Config byte array represented by a Base64 string
