如何使Android设备没有持有唤醒锁的TCP连接互联网？ [英] How to make the Android device hold a TCP connection to Internet without wake lock?

问题描述

我想我的应用程序连接到服务器，虽然在移动连接，但允许设备进入睡眠模式。我希望当IP packates到达时醒来。

I want my application to be connected to server though the mobile connection, yet allowing the device to go into sleep mode. I expect it to wake up when IP packates arrives.

如何才能做到这一点？如何接收来自互联网的中断不会耗尽电池？

How can this be done? How to receive "interrupts" from the Internet without draining battery?

推荐答案

在被封锁在从TCP读取数据流的设备可以进入深度睡眠，当TCP流量来自于它会短暂地唤醒器件，如一旦一个位的检查是在你开始wakelock，直到你收到整个传输然后松开。

When you are blocked on a read from a tcp stream the device can go into a deep sleep and when tcp traffic comes in it will briefly wakeup the device, as soon as a bit is read in you start a wakelock until you have received the whole transmission then release it.

下面是网络插座一个例子，我已经跑了这个应用程序超过12小时，不带电池影响的背景。 <一href="https://github.com/schwiz/android-websocket-example">https://github.com/schwiz/android-websocket-example

Here is an example with web sockets, I've ran this app for over 12 hours in the background with no battery impact. https://github.com/schwiz/android-websocket-example

The client is here, the blocking read is in the start method. https://github.com/schwiz/android-websockets/blob/master/src/com/codebutler/android_websockets/HybiParser.java
