Android - 无法启动接收器 com.parse.ParsePushBroadcastReceiver

Question

我正在尝试使用 Parse 测试一个非常基本的推送通知程序，但是当我广播通知时我的应用程序崩溃了。这是我的错误日志。

有人能告诉我为什么 ParsePushBroadcaseReceiver 没有启动吗？当我调用时，了解我的应用程序“无法订阅推送”也可能会有所帮助:

ParsePush.subscribeInBackground("channel_name", new SaveCallback() {
      @Override
      public void done(ParseException e) {
        if (e != null) {
          Log.v("com.parse.push", "successfully subscribed to the broadcast channel.");
        } else {
          Log.v("com.parse.push", "failed to subscribe for push", e);
        }
      }
    });

在项目的 list 中添加这一行。

 <meta-data
            android:name="com.parse.push.notification_icon"
            android:resource="@drawable/ic_launcher" />
