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

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.

有人可以告诉我为什么ParsePushbroadcaseReceiver没有启动？当我打电话时,知道我的应用程序“无法订阅推送”也可能有所帮助：

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);
        }
      }
    });

解决方法:

在项目清单中添加此行.

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