expo-noti-client

Basic HTTP/2 client to interact with the expo notification service. Works both asynchronously and synchronously using the Java HTTPClient class. Allows sending custom mobile notifications through Expo's Push API using a device id gathered from your own mobile device, which works both for IOS and Android devices.

Current Build 1.0.0 - Notes

Implementation to interact with Expo’s ticket service is not implemented yet. This part of the API can tell you if the notification has been sent, usually used when there is a high load and notifications are taking time to reach the user. This is currently being worked on.

Example Usage

Function to return a ExpoNTicket object which contains the success or failure of sending the notification to an example user, defined in the String testToken parameter.

package examples;

import java.util.ArrayList;
import java.util.List;

import client.ExpoNClient;
import client.types.ExpoNMessage;
import client.types.ExpoNTicket;

public class ExampleNotiTest {
    public ExpoNTicket PushExampleAsync(String testToken) {

        //Creating new client object to send the information to Expo's push API
        ExpoNClient client = new ExpoNClient();

        //Check if this is a valid token, this token is found from your device expo notification token, see the expo docs
        if (ExpoNClient.isExpoPushToken(testToken)) {
            List<String> tokens = new ArrayList<>();
            tokens.add(testToken);

            //Create a message objects which will send the notifcation information to the API
            ExpoNMessage message = ExpoNMessage.builder()
                .setTo(tokens)
                .setBody("Hello")
                .setTitle("Title")
                .setSubtitle("Subtitle")
            .build();

            try {
            
                //Send the message data, this is using async but joined straight away
                ExpoNTicket resp = client.sendExpoPushAsync(message).join();
                return resp;   
            } catch (Exception e) {
                System.out.println(e);
            }
        }

        return null;
    }
}
