当Android手机是睡着了网络访问 [英] Network access when the Android phone is asleep

问题描述

我用报警的组合（设定 AlarmManager ）和后台服务在我的应用程序定期同步数据。

I'm using a combination of alarm (set with AlarmManager) and background service to periodically synchronize data in my application.

唯一的问题我已经是当睡眠政策终止的Wi-Fi连接的同步不再工作。

The only problem I have is that when sleep policy terminates Wi-Fi connection the synchronization no longer works.

有没有办法来唤醒的Wi-Fi连接已被置于睡觉？ GMail的还是设法做到这一点，因为它会通知我关于新的电子邮件即使手机进入睡眠模式。

Is there a way to "wake up" the Wi-Fi connection that has been put to sleep? GMail somehow manages to do that because it notifies me about new e-mail even if the phone entered sleep mode.

推荐答案

[更新]您可以使用的 WifiLock 保持无线活跃，而持有该锁。

[update]You can use a WifiLock to keep WiFi active, while holding the lock.

使用 AlarmManager 和服务对我说：你的服务仅在很短的时间内运行！？我认为，（虽然不能肯定地说），你应该让你的服务forground服务（检查博客为实施这一两个1.x和2.x +的好办法），并离开 AlarmManager 出来。

Using an AlarmManager and a Service says to me your service is running only for a very short time!? I think (though can't say for certain) that you should make your service a forground service (check the blog for a good way to implement this on both 1.x and 2.x+) and leave the AlarmManager out of it.
