This is a java implementation of the node server-side library for working with expo using Java. For other implementations, see the expo docs.
Add package to your source tree (the package is not yet uploaded to e.g. Maven Central).
Then
import org.ubillos.pushnotifications.notificationsSDK.ExpoPushMessage;
import org.ubillos.pushnotifications.notificationsSDK.ExpoPushTicket;
import org.ubillos.pushnotifications.notificationsSDK.PushClient;
public class Main {
public static void main(String[] args) {
String recipient = "ExponentToken[XYZ]";
if (!PushClient.isExponentPushToken(receipient))
throw new Error("Token:" + receipient + " is not a valid token.");
PushClient client = new PushClient();
List<ExpoPushMessage> messages = new ArrayList<>();
ExpoPushMessage epm = new ExpoPushMessage(notifyRequest.to);
if (notifyRequest.title != null)
epm.title = notifyRequest.title;
if (notifyRequest.subtitle != null)
epm.subtitle = notifyRequest.subtitle;
if (notifyRequest.body != null)
epm.body = notifyRequest.body;
messages.add(epm);
List<List<ExpoPushMessage>> chunks = client.chunkPushNotifications(messages);
List<CompletableFuture<List<ExpoPushTicket>>> messageRepliesFutures = new ArrayList<>();
for (List<ExpoPushMessage> chunk : chunks) {
messageRepliesFutures.add(client.sendPushNotificationsAsync(chunk));
}
// Wait for each completable future to finish
List<ExpoPushTicket> allTickets = new ArrayList<>();
for (CompletableFuture<List<ExpoPushTicket>> messageReplyFuture : messageRepliesFutures) {
try {
for (ExpoPushTicket ticket : messageReplyFuture.get()) {
allTickets.add(ticket);
}
} catch (InterruptedException e) {
e.printStackTrace();
} catch (ExecutionException e) {
e.printStackTrace();
}
}
