React Native Local and Remote Notifications for iOS and Android



## State of the repository



This repository is not actively maintained. The main reason is time. The second one is probably the complexity of notifications on both iOS and Android.

Since this project probably need a huge refactor to fix some issue or to implement new features. I think you should probably consider these alternatives: [Notifee](https://notifee.app) free since september or [react-native-notifications](https://github.com/wix/react-native-notifications).



If you are interested in being a maintainer of this project, feel free to ask in issues.



## 🎉 Version 7.x is live ! 🎉

# Supporting the project



Maintainers are welcome ! Feel free to contact me :wink:



## Changelog



Changelog is available from version 3.1.3 here: [Changelog](https://github.com/zo0r/react-native-push-notification/blob/master/CHANGELOG.md)



## Installation



### NPM



```

npm install --save react-native-push-notification

```



### Yarn



```

yarn add react-native-push-notification

```



**NOTE: If you target iOS you also need to follow the [installation instructions for PushNotificationIOS](https://github.com/react-native-community/react-native-push-notification-ios) since this package depends on it.**



**NOTE: For Android, you will still have to manually update the AndroidManifest.xml (as below) in order to use Scheduled Notifications.**



## Issues



Having a problem? Read the [troubleshooting](./trouble-shooting.md) guide before raising an issue.



## Pull Requests



[Please read...](./submitting-a-pull-request.md)



## iOS manual Installation



The component uses PushNotificationIOS for the iOS part. You should follow their [installation instructions](https://github.com/react-native-community/react-native-push-notification-ios).



## Android manual Installation



**NOTE: `firebase-messaging`, prior to version 15 requires to have the same version number in order to work correctly at build time and at run time. To use a specific version:**



In your `android/build.gradle`



```gradle

ext {

    googlePlayServicesVersion = "" // default: "+"

    firebaseMessagingVersion = "" // default: "21.1.0"



    // Other settings

    compileSdkVersion =  // default: 23

    buildToolsVersion = "" // default: "23.0.1"

    targetSdkVersion =  // default: 23

    supportLibVersion = "" // default: 23.1.1

}

```



**NOTE: localNotification() works without changes in the application part, while localNotificationSchedule() only works with these changes:**



In your `android/app/src/main/AndroidManifest.xml`



```xml

    .....

    

    



    

        

        

        

         



        

        

        

            

                

                

                

            

        



        

            

                

            

        

     .....

```



If not using a built in Android color (`@android:color/{name}`) for the `notification_color` `meta-data` item.

In `android/app/src/main/res/values/colors.xml` (Create the file if it doesn't exist).



```xml



    #FFF



```



If your app has an @Override on onNewIntent in `MainActivity.java` ensure that function includes a super call on onNewIntent (if your `MainActivity.java` does not have an @Override for onNewIntent skip this):



```java

    @Override

    public void onNewIntent(Intent intent) {

        ...

        super.onNewIntent(intent);

        ...

    }

```



### If you use remote notifications



Make sure you have installed setup Firebase correctly.



In `android/build.gradle`



```gradle



buildscript {

    ...

    dependencies {

        ...

        classpath('com.google.gms:google-services:4.3.3')

        ...

    }

}

```



In `android/app/build.gradle`



```gradle

dependencies {

  ...

  implementation 'com.google.firebase:firebase-analytics:17.3.0'

  ...

}



apply plugin: 'com.google.gms.google-services'



```



Then put your `google-services.json` in `android/app/`.



**Note: [firebase/release-notes](https://firebase.google.com/support/release-notes/android)**



> The Firebase Android library `firebase-core` is no longer needed. This SDK included the Firebase SDK for Google Analytics.

>

> Now, to use Analytics or any Firebase product that recommends the use of Analytics (see table below), you need to explicitly add the Analytics dependency: `com.google.firebase:firebase-analytics:17.3.0`.



### If you don't use autolink



In `android/settings.gradle`



```gradle

...

include ':react-native-push-notification'

project(':react-native-push-notification').projectDir = file('../node_modules/react-native-push-notification/android')

```



In your `android/app/build.gradle`



```gradle

 dependencies {

    ...

    implementation project(':react-native-push-notification')

    ...

 }

```



Manually register module in `MainApplication.java` (if you did not use `react-native link`):



```java

import com.dieam.reactnativepushnotification.ReactNativePushNotificationPackage;  // <--- Import Package



public class MainApplication extends Application implements ReactApplication {



  private final ReactNativeHost mReactNativeHost = new ReactNativeHost(this) {

      @Override

      protected boolean getUseDeveloperSupport() {

        return BuildConfig.DEBUG;

      }



      @Override

      protected List getPackages() {



          return Arrays.asList(

              new MainReactPackage(),

              new ReactNativePushNotificationPackage() // <---- Add the Package

          );

    }

  };



  ....

}

```



## Usage



**DO NOT USE `.configure()` INSIDE A COMPONENT, EVEN `App`**

> If you do, notification handlers will not fire, because they are not loaded. Instead, use `.configure()` in the app's first file, usually `index.js`.



```javascript

import PushNotificationIOS from "@react-native-community/push-notification-ios";

import PushNotification from "react-native-push-notification";



// Must be outside of any component LifeCycle (such as `componentDidMount`).

PushNotification.configure({

  // (optional) Called when Token is generated (iOS and Android)

  onRegister: function (token) {

    console.log("TOKEN:", token);

  },



  // (required) Called when a remote is received or opened, or local notification is opened

  onNotification: function (notification) {

    console.log("NOTIFICATION:", notification);



    // process the notification



    // (required) Called when a remote is received or opened, or local notification is opened

    notification.finish(PushNotificationIOS.FetchResult.NoData);

  },



  // (optional) Called when Registered Action is pressed and invokeApp is false, if true onNotification will be called (Android)

  onAction: function (notification) {

    console.log("ACTION:", notification.action);

    console.log("NOTIFICATION:", notification);



    // process the action

  },



  // (optional) Called when the user fails to register for remote notifications. Typically occurs when APNS is having issues, or the device is a simulator. (iOS)

  onRegistrationError: function(err) {

    console.error(err.message, err);

  },



  // IOS ONLY (optional): default: all - Permissions to register.

  permissions: {

    alert: true,

    badge: true,

    sound: true,

  },



  // Should the initial notification be popped automatically

  // default: true

  popInitialNotification: true,



  /**

   * (optional) default: true

   * - Specified if permissions (ios) and token (android and ios) will requested or not,

   * - if not, you must call PushNotificationsHandler.requestPermissions() later

   * - if you are not using remote notification or do not have Firebase installed, use this:

   *     requestPermissions: Platform.OS === 'ios'

   */

  requestPermissions: true,

});

```



## Example app



Example folder contains an example app to demonstrate how to use this package. The notification Handling is done in `NotifService.js`.



Please test your PRs with this example app before submitting them. It'll help maintaining this repo.



## Handling Notifications



When any notification is opened or received the callback `onNotification` is called passing an object with the notification data.



Notification object example:



```javascript

{

    foreground: false, // BOOLEAN: If the notification was received in foreground or not

    userInteraction: false, // BOOLEAN: If the notification was opened by the user from the notification area or not

    message: 'My Notification Message', // STRING: The notification message

    data: {}, // OBJECT: The push data or the defined userInfo in local notifications

}

```



## Local Notifications



```js

PushNotification.localNotification(details: Object)

```



EXAMPLE:



```javascript

PushNotification.localNotification({

  /* Android Only Properties */

  channelId: "your-channel-id", // (required) channelId, if the channel doesn't exist, notification will not trigger.

  visibility: "private", // (optional) set notification visibility, default: private

  ignoreInForeground: false, // (optional) if true, the notification will not be visible when the app is in the foreground (useful for parity with how iOS notifications appear). should be used in combine with `com.dieam.reactnativepushnotification.notification_foreground` setting

  shortcutId: "shortcut-id", // (optional) If this notification is duplicative of a Launcher shortcut, sets the id of the shortcut, in case the Launcher wants to hide the shortcut, default undefined

  onlyAlertOnce: false, // (optional) alert will open only once with sound and notify, default: false

  

  when: null, // (optional) Add a timestamp (Unix timestamp value in milliseconds) pertaining to the notification (usually the time the event occurred). For apps targeting Build.VERSION_CODES.N and above, this time is not shown anymore by default and must be opted into by using `showWhen`, default: null.

  usesChronometer: false, // (optional) Show the `when` field as a stopwatch. Instead of presenting `when` as a timestamp, the notification will show an automatically updating display of the minutes and seconds since when. Useful when showing an elapsed time (like an ongoing phone call), default: false.

  timeoutAfter: null, // (optional) Specifies a duration in milliseconds after which this notification should be canceled, if it is not already canceled, default: null



  messageId: "google:message_id", // (optional) added as `message_id` to intent extras so opening push notification can find data stored by @react-native-firebase/messaging module.

  picture: "https://www.example.tld/picture.jpg", // (optional) Display an picture with the notification, alias of `bigPictureUrl` for Android. default: undefined

  userInfo: {}, // (optional) default: {} (using null throws a JSON value '' error)

  playSound: false, // (optional) default: true

  soundName: "default", // (optional) Sound to play when the notification is shown. Value of 'default' plays the default sound. It can be set to a custom sound such as 'android.resource://com.xyz/raw/my_sound'. It will look for the 'my_sound' audio file in 'res/raw' directory and play it. default: 'default' (default sound is played)

  number: 10, // (optional) Valid 32 bit integer specified as string. default: none (Cannot be zero)

  repeatType: "day", // (optional) Repeating interval. Check 'Repeating Notifications' section for more info.

});

```



## Scheduled Notifications



```js

PushNotification.localNotificationSchedule(details: Object)

```



EXAMPLE:



```javascript

PushNotification.localNotificationSchedule({

  //... You can use all the options from localNotifications

  message: "My Notification Message", // (required)

  date: new Date(Date.now() + 60 * 1000), // in 60 secs

  allowWhileIdle: false, // (optional) set notification to work while on doze, default: false



  /* Android Only Properties */

  repeatTime: 1, // (optional) Increment of configured repeatType. Check 'Repeating Notifications' section for more info.

});

```



## Get the initial notification



```js

PushNotification.popInitialNotification(callback)

```



EXAMPLE:



```javascript

PushNotification.popInitialNotification((notification) => {

  console.log('Initial Notification', notification);

});

```



## Custom sounds



In android, add your custom sound file to `[project_root]/android/app/src/main/res/raw`



In iOS, add your custom sound file to the project `Resources` in xCode.



In the location notification json specify the full file name:



    soundName: 'my_sound.mp3'



## Channel Management (Android)



To use channels, create them at startup and pass the matching `channelId` through to `PushNotification.localNotification` or `PushNotification.localNotificationSchedule`.



```javascript

import PushNotification, {Importance} from 'react-native-push-notification';

...

  PushNotification.createChannel(

    {

      channelId: "channel-id", // (required)

      channelName: "My channel", // (required)

      channelDescription: "A channel to categorise your notifications", // (optional) default: undefined.

      playSound: false, // (optional) default: true

      soundName: "default", // (optional) See `soundName` parameter of `localNotification` function

      importance: Importance.HIGH, // (optional) default: Importance.HIGH. Int value of the Android notification importance

      vibrate: true, // (optional) default: true. Creates the default vibration pattern if true.

    },

    (created) => console.log(`createChannel returned '${created}'`) // (optional) callback returns whether the channel was created, false means it already existed.

  );

```



**NOTE: Without channel, notifications don't work**



In the notifications options, you must provide a channel id with `channelId: "your-channel-id"`, if the channel doesn't exist the notification might not be triggered. Once the channel is created, the channel cannot be updated. Make sure your `channelId` is different if you change these options. If you have created a channel in another way, it will apply options of the channel.



If you want to use a different default channel for remote notification, refer to the documentation of Firebase:



[Set up a Firebase Cloud Messaging client app on Android](https://firebase.google.com/docs/cloud-messaging/android/client?hl=fr)



```xml

  

```



For local notifications, the same kind of option is available:



- you can use:

  ```xml

    

  ```

- If not defined, fallback to the Firebase value defined in the `AndroidManifest`:

  ```xml

    

  ```

- If not defined, fallback to the default Firebase channel id `fcm_fallback_notification_channel`



### List channels



You can list available channels with:



```js

PushNotification.getChannels(function (channel_ids) {

  console.log(channel_ids); // ['channel_id_1']

});

```



### Channel exists



You can check if a channel exists with:



```js

PushNotification.channelExists(channel_id, function (exists) {

  console.log(exists); // true/false

});

```



### Channel blocked



You can check if a channel blocked with:



```js

PushNotification.channelBlocked(channel_id, function (blocked) {

  console.log(blocked); // true/false

});

```



### Delete channel



You can delete a channel with:



```js

PushNotification.deleteChannel(channel_id);

```



## Cancelling notifications



### 1) cancelLocalNotification



The `id` parameter for `PushNotification.localNotification` is required for this operation. The id supplied will then be used for the cancel operation.



```javascript

PushNotification.localNotification({

    ...

    id: '123'

    ...

});

PushNotification.cancelLocalNotification('123');

```



### 2) cancelAllLocalNotifications

Available options:



```

"max" = NotficationCompat.PRIORITY_MAX\

"high" = NotficationCompat.PRIORITY_HIGH\

"low" = NotficationCompat.PRIORITY_LOW\

"min" = NotficationCompat.PRIORITY_MIN\

"default" = NotficationCompat.PRIORITY_DEFAULT

```



More information: https://developer.android.com/reference/android/app/Notification.html#PRIORITY_DEFAULT



## Notification visibility

Available options:



```

"private" = NotficationCompat.VISIBILITY_PRIVATE\

"public" = NotficationCompat.VISIBILITY_PUBLIC\

"secret" = NotficationCompat.VISIBILITY_SECRET 

```

More information: https://developer.android.com/reference/android/app/Notification.html#VISIBILITY_PRIVATE



## Notification importance

Constants available on the `Importance` object. `import PushNotification, {Importance} from 'react-native-push-notification';`



Available options:

```

Importance.DEFAULT = NotificationManager.IMPORTANCE_DEFAULT\

Importance.HIGH = NotificationManager.IMPORTANCE_HIGH\

Importance.LOW = NotificationManager.IMPORTANCE_LOW\

Importance.MIN = NotificationManager.IMPORTANCE_MIN\

Importance.NONE= NotificationManager.IMPORTANCE_NONE\

Importance.UNSPECIFIED = NotificationManager.IMPORTANCE_UNSPECIFIED

```



More information: https://developer.android.com/reference/android/app/NotificationManager#IMPORTANCE_DEFAULT



## Show notifications while the app is in foreground



If you want a consistent results in Android & iOS with the most flexibility, it is best to handle it manually by prompting a local notification when `onNotification` is triggered by a remote push notification on foreground (check `notification.foreground` prop).



Watch out for an infinite loop triggering `onNotification` - remote & local notification will trigger it. You can overcome this by marking local notifications' data.



## Notification while idle



(optional) Specify `allowWhileIdle` to set if the notification should be allowed to execute even when the system is on low-power idle modes.



On Android 6.0 (API level 23) and forward, the Doze was introduced to reduce battery consumption when the device is unused for long periods of time. But while on Doze the AlarmManager alarms (used to show scheduled notifications) are deferred to the next maintenance window. This may cause the notification to be delayed while on Doze.



This can significantly impact the power use of the device when idle. So it must only be used when the notification is required to go off on a exact time, for example on a calendar notification.



More information:

https://developer.android.com/training/monitoring-device-state/doze-standby



## Repeating Notifications



(optional) Specify `repeatType` and optionally `repeatTime` (Android-only) while scheduling the local notification. Check the local notification example above.



### iOS

Property `repeatType` can only be `month`, `week`, `day`, `hour`, `minute`.



NOTE: `repeatTime` do not work with iOS.



### Android

Property `repeatType` could be one of `month`, `week`, `day`, `hour`, `minute`, `time`. 



The interval used can be configured to a different interval using `repeatTime`. If `repeatType` is `time`, `repeatTime` must be specified as the number of milliseconds between each interval.

For example, to configure a notification every other day



```javascript

PushNotification.localNotificationSchedule({

    ...

    repeatType: 'day',

    repeatTime: 2,

    ...

});

```



## Notification Actions



(Android Only)



This is done by specifying an `actions` parameters while configuring the local notification. This is an array of strings where each string is a notification action that will be presented with the notification.



For e.g. `actions: ['Accept', 'Reject']`



When you handle actions in background (`invokeApp: false`), you can open the application and pass the initial notification by using use `PushNotification.invokeApp(notification)`.



Make sure you have the receiver in `AndroidManifest.xml`:



```xml

  

```



Notifications with inline reply: 



You must register an action as "ReplyInput", this will show in the notifications an input to write in. 



EXAMPLE:

```javascript

PushNotification.localNotificationSchedule({

  message: "My Notification Message", // (required)

  date: new Date(Date.now() + (60 * 1000)), // in 60 secs

  actions: ["ReplyInput"],

  reply_placeholder_text: "Write your response...", // (required)

  reply_button_text: "Reply" // (required)

});

```



To get the text from the notification: 



```javascript

...

if(notification.action === "ReplyInput"){

  console.log("texto", notification.reply_text)// this will contain the inline reply text. 

}

...

```



For iOS, you can use:



```javascript

PushNotification.setNotificationCategories(categories);

```



And use the `category` field in the notification.



Documentation [here](https://github.com/react-native-push-notification-ios/push-notification-ios#how-to-perform-different-action-based-on-user-selected-action) to add notification actions.



## Set application badge icon



```js

PushNotification.setApplicationIconBadgeNumber(number: number)

```



Works natively in iOS.



Uses the [ShortcutBadger](https://github.com/leolin310148/ShortcutBadger) on Android, and as such will not work on all Android devices.



## Android Only Methods



```js

PushNotification.subscribeToTopic(topic: string)

```

Subscribe to a topic (works only with Firebase)



```js

PushNotification.unsubscribeFromTopic(topic: string)

```

Unsubscribe from a topic (works only with Firebase)



## Android Custom Notification Handling



Unlike iOS, Android apps handle the creation of their own notifications. React Native Push Notifications does a "best guess" to create and handle incoming notifications. However, when using 3rd party notification platforms and tools, the initial notification creation process may need to be customized.



### Customizing Notification Creation



If your notification service uses a custom data payload format, React Native Push Notifications will not be able to parse the data correctly to create an initial notification.



For these cases, you should:



1. Remove the intent handler configuration for React Native Push Notifications from your `android/app/src/main/AndroidManifest.xml`.

2. Implement initial notification creation as per the instructions from your Provider.



### Handling Custom Payloads



Data payloads of notifications from 3rd party services may not match the format expected by React Native Push Notification. When tapped, these notifications will not pass the details and data to the `onNotification()` event handler. Custom `IntentHandlers` allow you to fix this so that correct `notification` objects are sent to your `onNotification()` method.



Custom handlers are added in Application init or `MainActivity.onCreate()` methods:



```java

RNPushNotification.IntentHandlers.add(new RNPushNotification.RNIntentHandler() {

  @Override

  public void onNewIntent(Intent intent) {

    // If your provider requires some parsing on the intent before the data can be

    // used, add that code here. Otherwise leave empty.

  }



  @Nullable

  @Override

  public Bundle getBundleFromIntent(Intent intent) {

    // This should return the bundle data that will be serialized to the `notification.data`

    // property sent to the `onNotification()` handler. Return `null` if there is no data

    // or this is not an intent from your provider.

    

    // Example:

    if (intent.hasExtra("MY_NOTIFICATION_PROVIDER_DATA_KEY")) {

      return intent.getBundleExtra("MY_NOTIFICATION_PROVIDER_DATA_KEY");

    }

    return null;

  }

});

```



## Checking Notification Permissions



```js

PushNotification.checkPermissions(callback: Function) //Check permissions

```



`callback` will be invoked with a `permissions` object:



- `alert`: boolean

- `badge`: boolean

- `sound`: boolean



## iOS Only Methods



```js

PushNotification.getApplicationIconBadgeNumber(callback: Function) //Get badge number

```
