addProximityAlert doesn't work as expected

阅读更多关于 addProximityAlert doesn't work as expected

ios sdk has great region monitoring functions. I need something like that in android and i think we have two alternatives. Geofencing and LocationManager. Geofencing has really tidy examples and bugs , so i prefered LocationManager. Everyting works fine in LocationManager except one. If you add your current location as ProximityAlert , it immediatly fires "ENTERING" , but it is my current location , it doesnt mean that i entered this region. Because of that , it fires "ENTERING" each time i start my application if i am in region.(Even if i am not moving) How can i solve this problem and fire

问题 server { listen 80; server_name pwta; root html; location /test/{ alias html/test/; autoindex on; } location ~ \.php$ { fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } } This configuration works. However, if location /test/ is replaced e.g. location /testpath/ it doesn't work (No input file specified). I assumed base on the explanation of alias directive that the "location" part is dropped and

问题 I've been working on this for the past 2 weeks - i have an app that shows a legible route on a map that goes from a start point to a destination point. the destination point is the users address (as defined/entered by the user in the settings menu we have set up) and if i hard code the start point, the map, route and application all work fine. once i try to implement anything that involves using the cllocation or cllocationmanager, it crashes and gives me a thread error (there are 3).

Nginx 配置详细文件

阅读更多关于 Nginx 配置详细文件

概述 Nginx 是使用一个 master 进程来管理多个 worker 进程提供服务。master 负责管理 worker 进程，而 worker 进程则提供真正的客户服务，worker 进程的数量一般跟服务器上 CPU 的核心数相同，worker 之间通过一些进程间通信机制实现负载均衡等功能。Nginx 进程之间的关系可由下图表示： Nginx 服务启动时会读入配置文件，后续的行为则按照配置文件中的指令进行。Nginx 的配置文件是纯文本文件，默认安装 Nginx 后，其配置文件均在 /usr/local/nginx/conf/ 目录下。其中，nginx.conf 为主配置文件。配置文件中以 # 开始的行，或者是前面有若干空格或者 TAB 键，然后再跟 # 的行，都被认为是注释。这里只是了解主配置文件的结构。 Nginx 配置文件是以 block（块）形式组织，每个 block 都是以一个块名字和一对大括号 “{}” 表示组成，block 分为几个层级，整个配置文件为 main 层级，即最大的层级；在 main 层级下可以有 event、http 、mail 等层级，而 http 中又会有 server block，server block中可以包含 location block。即块之间是可以嵌套的，内层块继承外层块。最基本的配置项语法格式是“配置项名配置项值1 配置项值2

How to animate a marker through an ArrayList of LatLng points?

阅读更多关于 How to animate a marker through an ArrayList of LatLng points?

I am using Google Maps API V2 to get the location of the current user and am recording his route by using the onLocationChanged listener. While the user records their route I save all the LatLngs detected at each location change in an arraylist. When the user stops recording their route I place a marker at the first point in the arraylist. My problem now is that I wish to animate the marker through all the points in the arraylist. Can someone please tell me how can I do this? Things to note is that the array doesn't need sorting because I record the points as they come. I have tried using a

Location headers in Laravel

阅读更多关于 Location headers in Laravel

I'm working with a Library for my university's authentication system (Ucam_Webauth) which means I have to redirect to the authentication server in one of the methods. Unfortunately, I cannot return a Redirect:to() because of the architecture of this library. The library itself uses header('Location: ...'); but this isn't working for some reason. If I make the programme die(); after sending the header it works, but otherwise it doesn't. Any idea how I can fix this? I'm not sure I follow. Laravel sets the Location header as part of the Redirect::to() method. If you want to more explicitly define
