java – Google Cloud Messaging – 即时或长时间收到的消息

我已经看过这个,我真的不认为这适用于这种情况：

GCM will usually deliver messages immediately after they are sent.
However,this might not always be possible. For example,the device
could be turned off,offline,or otherwise unavailable. In other
cases,the sender itself might request that messages not be delivered
until the device becomes active by using the delay_while_idle flag.
Finally,GCM might intentionally delay messages to prevent an
application from consuming excessive resources and negatively
impacting battery life.

在我的项目中,一分钟就从服务器上发出了最多5或6条消息.如果GCM可以用于聊天应用程序,肯定他们无法阻止以这种速率发送/接收的消息？如果我的项目只在50％的时间工作,那么它变得非常烦人,会非常糟糕

这是服务器发送的消息的代码：

@Override
public void run() {

    Message.Builder messageBuilder = new Message.Builder().delayWhileIdle(false);
    Gson gson = new Gson();
    messageBuilder.addData("profile",gson.toJson(profile));
    databaseConnection.notifyDevices(messageBuilder.build());

}

public void notifyDevices(Message message) {

        Sender sender = new Sender(xxx);

        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
        nameValuePairs.add(new BasicNameValuePair("message",message.toString()));

        //LOG
        System.out.println("Notifying devices with the following message n "" +message+ """);

        List<String> deviceIDsList = new ArrayList<String>();
        String [] deviceIDArray;

        //Get devices to notify
        List<JSONDeviceProfile> deviceList = getDevicesToNotify();

        for(JSONDeviceProfile device : deviceList) {
            deviceIDsList.add(device.getDeviceId());

            try {
                sender.send(message,device.getDeviceId(),5);
            } catch (IOException e) {
                System.out.println("Error sending GCM message!");
                e.printStackTrace();
            }
        }
}

和我的Android onMessage方法：

@Override
protected void onMessage(Context arg0,Intent intent) {

    String message = intent.getStringExtra("profile");

    Log.d(TAG + "Received Message: ","Received Message: " + message.toString());

    //CALL NEW INTENT WITH PROFILE DETAILS
    Intent displayProfileIntent = new Intent(arg0,DisplayProfile.class);
    displayProfileIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    displayProfileIntent.putExtra("message",message); 
    startActivity(displayProfileIntent);

    /*
    //generateNotification(arg0,username);

    handler.post(new Runnable() {
        @Override
        public void run() {
            //Toast.makeText(getApplicationContext(),username,Toast.LENGTH_SHORT).show();

        }
    });
    */
}

我希望有人有类似的问题,我只想确认问题是我正在做的事情,或者是我的手中.

tl; dr GCM消息可以立即到达或大约10分钟后(延迟通常是一致的).
