Firebase通知未從Java代碼發送

[英]Firebase notification not sending from Java code

 原文  2017-04-13 00:36:59  8   1    java/ android/ firebase/ firebase-cloud-messaging

問題描述

我可以將通知從Firebase控制台成功發送到我的設備，但是當我嘗試從Java代碼執行通知時，出現一個非常無用的錯誤： 

04-12 20:18:09.284 17549-17549/com.package.example W/System.err:       at com.package.example.FCMNotification.pushFCMNotification(FCMNotification.java:102)

這是我的FCMNotification類別 

public class FCMNotification {
public final static String AUTH_KEY_FCM = "FCM_SERVERKEY";
public final static String API_URL_FCM = "https://fcm.googleapis.com/fcm/send";

public static void pushFCMNotification(String deviceToken, String title, String body)
        throws IOException, JSONException {
    String authKey = AUTH_KEY_FCM;   // You FCM AUTH key
    String FMCurl = API_URL_FCM;

    URL url = new URL(FMCurl);
    HttpURLConnection conn = (HttpURLConnection) url.openConnection();

    conn.setUseCaches(false);
    conn.setDoInput(true);
    conn.setDoOutput(true);

    conn.setRequestMethod("POST");
    conn.setRequestProperty("Authorization","key="+authKey);
    conn.setRequestProperty("Content-Type","application/json");

    JSONObject json = new JSONObject();
    json.put("to",deviceToken.trim());
    JSONObject info = new JSONObject();
    info.put("title", title);   // Notification title
    info.put("body", body); // Notification body
    json.put("notification", info);

    OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream());
    wr.write(json.toString());
    wr.flush();
    conn.getInputStream();
  }
}

我在這樣的活動中稱這堂課 

FCMNotification obj = new FCMNotification();
obj.pushFCMNotification("DEVICE_TOKEN", "TITLE", "BODY");

編輯

我的應用可能無法連接到Firebase服務器本身，因此我包含了清單和Gradle：
