我的纵横

模仿谷歌纵横的应用，可在后台被动地记录用户到过的地点，同时可以查看好友的位置。

因谷歌纵横被关闭，市面上却没有好用的替代品，在我寻找了很久之后，我就打算自己做一个。但我并不喜欢 Java 开发，虽然已经决定做一个，却迟迟没有动手，一直拖到现在。

既然是谷歌纵横的替代品，那么各方面的功能都会和原有的谷歌纵横相当。另外，我非常厌恶那些滥用权限、狂吃电量的国产应用，这个应用自然只会要求最少的权限，并尽我所能减少电量消耗。

特性
* 显示 24 小时内的自己的移动轨迹
* 在地图上显示好友的位置
* 支持且仅支持使用谷歌账号登录（国内什么新浪微信之流不考虑）
* 与谷歌纵横一样，使用被动位置源（Passive Provider）获取位置信息，获取位置信息不消耗额外的电量，使耗电最小化
* 持续记录位置，定期上传位置信息。可以设置为仅上传最新的位置信息，以降低电池和流量消耗
* 检测到无线网络时自动上传旧的位置信息

权限说明
国内很多应用经常申请一长串权限，有很多权限根本与应用的需求无关，不知这些应用的开发商是无心之过，或是行苟且之事。用户应该有权利知道应用申请权限之用途，在此我将本应用申请的所有权限用途解释如下。
* 完全的网络访问权限
用于上传位置信息到云端。请放心，所有与网络有关的行为皆经由 HTTPS 传输，不会有被监听的风险。
* 大致位置（基于网络）
* 精确位置（基于 GPS 和网络）
这两项权限用于获取位置信息。
* 开机启动
用于开机时自动启动后台位置记录服务，以便开机后能够自动记录位置。
* 查看 WLAN 连接
* 查看网络连接
用于监视网络状态变化，以便在连接到可用的 WLAN 网络时自动上传旧的位置信息。

性能
“我的纵横”的用户界面使用 HTML5 技术构建，而 HTML5 应用的性能很是糟糕（相对于原生应用来说）。为了提高性能，建议您安装“Android 系统 WebView”（https://play.google.com/store/apps/details?id=com.google.android.webview），这可以显著提升 HTML5 应用的性能。

隐私
保存位置信息的服务器位于美国，且数据未加密存放，故国外相关机构（你懂的）有能力在我不知情的情况下获取所有的位置信息及位置历史，以及您的谷歌账号唯一编号（google uid)。


其他
如前文所述，我只是半路起家的非专业 Android 开发人员，且不喜欢 Java 开发，所以应用界面是借助 PhoneGap 使用 HTML 5 构建的。而 HTML 5 应用程序在性能上存在不可克服问题，故使用应用时可能遇到卡顿等问题，请保持耐心，应用并没有死掉，只是反应慢了一些而已。

鸣谢
感谢 +DendriformCola 提供的应用图标以及大量界面改进建议 Imitate Google Latitude application, can passively record the user visited place in the background, while you can view your friends' locations.

Because Google Latitude is closed, the market was not easy alternatives, after I was looking for a long time, I intend to make a. But I do not like Java development, although already decided to do a, has as yet no hands, till now.

Since it is a substitute for Google Latitude, then all aspects and functions are quite original Google Latitude. In addition, I am very loathe those who abuse authority, domestic consumption binge application, this application only requires a minimum of natural rights, and do my best to reduce power consumption.

characteristic
* Show their movement locus within 24 hours
* Show your friends' locations on a map
* Support and only supports Google account login (what domestic Sina and his ilk do not consider the letter)
* And Google Latitude, the use of passive location sources (Passive Provider) to obtain location information, obtain location information does not consume additional power, so the power consumption is minimized
* Continuous recording location, upload location information periodically. It can be set to only upload the latest location information to reduce battery consumption and flow
* Old location information is automatically uploaded to a wireless network is detected

Permission Description
Many domestic applications often apply a long list of rights has nothing to do a lot of competence and application requirements, application developers do not know which is intentional, or the line is having an affair. Users should have the right to know to apply for permission to use the application, all rights I use in this application of the present application are explained below.
* Full network access
Location information for uploading to the cloud. Please be assured that all network-related behaviors are transmitted via HTTPS, without the risk of being monitored.
* Approximate location (network-based)
* Precise location (GPS and network-based)
These two permissions are used to obtain location information.
* Boot
Automatically start recording background location services for power to be able to automatically record the location of the boot.
* View WLAN connection
* View Network Connections
For monitoring network status changes to automatically upload the old location information when connected to an available WLAN network.

performance
"My aspect" of the user interface using HTML5 technology to build, while the performance of HTML5 applications is very bad (as opposed to native applications). To improve performance, we recommend that you install the "Android System WebView" (https://play.google.com/store/apps/details?id=com.google.android.webview), which can significantly improve the performance of HTML5 applications.

privacy
Save location information server located in the US, and the data is stored unencrypted, so foreign-related institutions (you know) have the ability to get all of the location information and location history in my knowledge, and your Google account unique number (google uid).


other
As mentioned before, I just started halfway non-professional Android developers, and not like Java development, the application interface is the use of HTML 5 built using PhoneGap. The HTML 5 application exists in the performance of insurmountable problems and other issues that may be encountered when Caton so the use of the application, please be patient, the application did not die, but some of it is slow to respond.
