set FCM high-priority when using firebase-admin - firebase

Question

I have the following code which uses firebase-admin to send messages using Firebase cloud messaging
Message message = null;
message = Message.builder().putData("From", fromTel).putData("To", toTel).putData("Text", text)
.setToken(registrationToken).build();
String response = null;
try {
response = FirebaseMessaging.getInstance().sendAsync(message).get();
responseEntity = new ResponseEntity<String>(HttpStatus.ACCEPTED);
} catch (InterruptedException | ExecutionException e) {
e.printStackTrace();
}
System.out.println("Successfully sent message: " + response);
The above code works fine. But I need to send "high-priority" messages so that the device can receive them while in doze mode.
How can I make the messages "high-priority"?

Answer 1

For sending to Android devices, when building the message, set its AndroidConfig to a value that has Priority.HIGH:
AndroidConfig config = AndroidConfig.builder()
.setPriority(AndroidConfig.Priority.HIGH).build();
Message message = null;
message = Message.builder()
.putData("From", fromTel).putData("To", toTel).putData("Text", text)
.setAndroidConfig(config) // <= ADDED
.setToken(registrationToken).build();
For additional details, see the example in the documentation.
When sending to Apple devices, use setApnsConfig(), as explained in the documentation.

This may help somebody.
public String sendFcmNotification(PushNotificationRequestDto notifyRequest) throws FirebaseMessagingException {
String registrationToken = notifyRequest.getToken();
AndroidConfig config = AndroidConfig.builder()
.setPriority(AndroidConfig.Priority.HIGH).build();
Notification notification = Notification.builder()
.setTitle(notifyRequest.getTitle())
.setBody(notifyRequest.getBody())
.build();
Message message = Message.builder()
.setNotification(notification)
// .putData("foo", "bar")
.setAndroidConfig(config)
.setToken(registrationToken)
.build();
return FirebaseMessaging.getInstance().send(message);
}

public async Task send_PushNotification(FirebaseAdmin.Messaging.Message MESSAGE)
{
var defaultApp = FirebaseApp.Create(new AppOptions()
{
Credential = GoogleCredential.FromFile(Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "key_FB.json")),
});
var message = MESSAGE;
message.Token = FB_TOKEN;
message.Android = new AndroidConfig();
message.Android.Priority = Priority.High;
message.Android.TimeToLive = new TimeSpan(0,0,5);
var messaging = FirebaseMessaging.DefaultInstance;
var result = await messaging.SendAsync(message);
Console.WriteLine(result);
}

Without an AndroidConfig Builder
function sendFCM(token, from, to, text) {
var admin = require("firebase-admin");
var data = {
from: from,
to: to,
text: text
};
let message = {
data: data,
token: token,
android: {
priority: "high", // Here goes priority
ttl: 10 * 60 * 1000, // Time to live
}
};
admin.messaging()
.send(message)
.then((response) => {
// Do something with response
}).catch((error) => {
console.log(error);
});
}
