GCM字符串而不是布尔值

Question

我收到了来自GCM的消息,但我得到了字符串而不是布尔值.似乎问题在于我的JSON数组.我收到警告信息:

04-17 00:41:04.058: W/Bundle(6702): Key alarm expected Boolean but value was a java.lang.String.  The default value false was returned.
04-17 00:41:04.058: W/Bundle(6702): Attempt to cast generated internal exception:

PHP发送脚本.

   $devices = array();
   $data = array();
   array_push($devices, getRegId($user_id, $mysqli));
   $data = array("alarm" => true);

   SendGCM(true, $devices, $data);

JSON消息:

{"registration_ids":["APA91bFjtwqq2q5Ji88JjLjuivAzNVGxLDYXaIahCeRUOmaD6vb0T5C22uQSlygztpq_KsVGCZ-0TKQTqUsmp0PU4FXjKYfdsfsdfaxRM1gQ7oh5xHf576-JwQ9FuItsBvhQeQmiKoX3UIi0s3onBh9vO7wI3_Pvw"],"data":{"alarm":true}}

最后我的OnMessage方法:

@Override
    protected void onMessage(Context context, Intent intent) {

        boolean alarm = false;

        alarm = intent.getBooleanExtra("alarm", false);


    }

当邮件发送给您时,它是一个字符串,引用Google 发送消息下的在线文档,请求格式 "数据"部分:

值可以是任何JSON对象,但我们建议使用字符串,因为无论如何,值都将转换为GCM服务器中的字符串.如果要包含对象或其他非字符串数据类型(例如整数或布尔值),则必须自行转换为字符串.
