当应用程序关闭时将LocationListener的工作？ [英] will locationListener work when application is off?
本文介绍了当应用程序关闭时将LocationListener的工作？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我想送GPS位置到服务器的每5分钟，
甚至当我的应用程序已关闭。
我明白AlertManager可以preform这一点。
会是相同的效率明智的设置与LocationMaanger
minTime = 5分钟
minGPS_delta = 0
在一般的时候你可以使用：
1）View.postDelay（）;
2）LocationMaanger.setListener（）与minTime = 5分钟并minGPS_delta = 0
3）AlertManager
4）定时

对不起，迟到的答复...
I want to send a GPS location to the server every 5 minutes,
Even when my application is off.
I understand AlertManager can preform this.
would it be the same efficiency wise to set a LocationMaanger with
minTime = 5 min minGPS_delta = 0
in general when would you use:
1) View.postDelay();
2) LocationMaanger.setListener() with minTime = 5 min and minGPS_delta = 0
3) AlertManager
4) Timer
