Android Location update

阅读更多关于 Android Location update

问题 Im writing an android aplication in which is required the actual location of the user, but I'm having trouble acquiring that location. I'm using a LocationListener to listen for the location update, via Wifi (NETWORK_PROVIDER). The problem is I don't get an update, and I imagine it only happens when I change network. If I don't get updates, I can use lastKnowLocation but it does not provide me with the actual user's location. Is there a way to force a location update, via NETWORK_PROVIDER?

LocationClient does not update getLastLocation() on emulator

问题 I'm using the google play services api to get location updates in my app. However, for some reason, client.getLastLocation() doesn't changes its value when a client is connected. Only after requesting location updates by registering a listener will the location change. I think it may be an emulator only problem, but even when I manually change the location using ddms or telnet, the value of getLastLocation() still doesn't change. Unfortunately, my phone isn't showing up in adb, so I can't

问题 I'm building an iOS app using phonegap. I'm trying to get iOS to update its current position to my app when the app runs in the background. I've registered the location updates background mode however it's not reliable. After some research, I believe that iOS is automatically pausing the location updates. There's an attribute in CLLocationManager called 'pausesLocationUpdatesAutomatically' that I think is responsible for this behavior. The following declaration is from CLLocationManager.h in

该指令一般用于对请求的客户端直接返回响应状态码。在该作用域内 return后面的所有nginx配置都是无效的。可以使用在 server、location以及 if配置中。除了支持跟状态码，还可以跟字符串或者url链接。直接返回状态码：示例1： server{ listen 80; server_name www.aming.com; return 403; rewrite /(.*) /abc/$1; //该行配置不会被执行。 } 示例2： server { ..... if ($request_uri ~ "\.htpasswd|\.bak") { return 404; rewrite /(.*) /aaa.txt; //该行配置不会被执行。 } //如果下面还有其他配置，会被执行。 ..... } 返回字符串：示例3： server{ listen 80; server_name www.aming.com; return 200 "hello"; } 说明：如果要想返回字符串，必须要加上状态码，否则会报错。还可以支持json数据示例4： location ^~ /aming { default_type application/json ; return 200 '{"name":"aming","id":"100"}'; } 也支持写一个变量示例5：
