C2DM的Android手机睡眠 [英] Android C2DM sleeping phone
问题描述
根据此内容的Android C2DM保持插座活着有心跳机制，使得它能够接收推送消息。这使我希望我可以用一个积极的WiFi连接睡觉手机传递消息。
According to this Android C2DM keeps a socket alive with a heartbeat mechanism, making it able to receive push messages. This made me hope I could deliver messages to sleeping phones with an active wifi connection.
我做了一个实现设置delay_while_idle为0。如果我的手机的屏幕已关闭的消息传递，但如果手机进入睡眠状态（与间隔20分钟，1-6小时测试）。
I've made an implementation setting the "delay_while_idle" to '0'. The message is delivered if my phones' screen is powered off, but not if the phone goes to sleep (tested with intervals 20mins, 1-6 hours).
我已经获得了部分CPU锁+以防万一一个完整的无线网络锁。
I have acquired a partial cpu lock + a full wifi lock just in case.
有我只是使某种根本性错误还是我误解了C2DM推送功能？
Have I simply made something fundamentally wrong or did I misunderstand the C2DM push functionality?
我可以发送邮件到睡觉的手机不？
Can I send messages to sleeping phones or not?
推荐答案
使用alarmmanager而不是wakelocks的可以保持您的手机活着刚刚够。看到这个实施。将测试这种变体。
Using alarmmanager instead of wakelocks could keep your phone alive just enough. See this implementation. Will test a variant of this.
