如何在BroadcastReceiver中接收解析通知的消息

Question

如何在BroadcastReceiver中接收解析通知消息？ 我想通过解析通知显示通知的标题：

package com.parse.tutorials.pushnotifications;


public class RetrieveNotify extends BroadcastReceiver {
    private static final String TAG = "RetrieveNotify";

      @Override
      public void onReceive(Context context, Intent intent) {
        try {
          String action = intent.getAction();
          if(action.equals(TAG)){


          String channel = intent.getExtras().getString("com.parse.Channel");
          JSONObject json = new JSONObject(intent.getExtras().getString("com.parse.Data"));

          Log.e(TAG, "got action " + action + " on channel " + channel + " with:");
          Iterator itr = json.keys();
          while (itr.hasNext()) {
            String key = (String) itr.next();
            Log.e(TAG, "..." + key + " => " + json.getString(key));
           }
          }
        } catch (JSONException e) {
          Log.e(TAG, "JSONException: " + e.getMessage());
        }
      }
    }

我想在log.e：

中收到此消息

虽然我收到了你好世界！通知，我没有任何log.e！

Answer 1

解析后来的SDK版本的默认行为是推送通知。您可以选择接收推送消息。

Answer 2

根据您的清单，使用parse webconsole

发送这样的JSON警报

{ "message": "Here goes the promotional text", "messageTitle": "Promotional Title", "action": "RetrieveNotify" }

在您的广播接收器中，

    public void onReceive(final Context context, final Intent intent) {

        action = intent.getAction();

if (action.equals("RetrieveNotify"){
            notificationPayload = new JSONObject(intent.getExtras().getString("com.parse.Data"));

            message = notificationPayload.getString("message");
            messageTitle = notificationPayload.getString("messageTitle");

//记录您的变量     }
