Phonegap geolocation sometimes not working on android
提问by WuZhonghua
I have using cordova v3.4.1 to build android and ios app, on ios geolocation function is returning very quickly and works fine always,but on android, sometimes it not working.
我使用cordova v3.4.1 来构建android 和ios 应用程序，在ios 上的地理定位功能返回非常快并且始终工作正常，但是在android 上，有时它不起作用。
The strange thing is after I reboot my android phone,it works fine. In more than a few hours geolocation gets the postion very quickly both in wifi and 3G.
奇怪的是在我重新启动我的安卓手机后，它工作正常。在几个多小时内，地理定位在 wifi 和 3G 中都很快得到了定位。
But after serval hours, I open the app again, the geolocation can not work.Sometimes when I outside, it can get postion with gps satellite,but very slow,often occur timeout error.
但是几个小时后，我再次打开应用程序，地理定位无法工作。有时我在外面时，可以使用gps卫星定位，但速度很慢，经常出现超时错误。
I try to remove the app and reinstall it again,but the problem still exist,unless reboot my android phone.when I reboot my android phone,geolocation function is working fine again in future a few hours.
我尝试删除该应用程序并重新安装它，但问题仍然存在，除非重新启动我的 android 手机。当我重新启动我的 android 手机时，地理定位功能在未来几个小时内再次正常工作。
I have test serval android`s phone such as samsang note2, galaxy4 etc, they all have the same problem.when I reboot it, they can get location very quicly.
我测试了 samsang note2、galaxy4 等 serval android 手机，它们都有相同的问题。当我重新启动它时，它们可以非常快速地获取位置。
This problem has troubled me for a long time, so somebody help me?
这个问题困扰我很久了，有人帮帮我吗？
here is my code below:
这是我的代码如下：
navigator.geolocation.getCurrentPosition(function(pos){
cb(null,pos)
},function(errMsg){
navigator.geolocation.getCurrentPosition(function(pos){
cb(null,pos)
},function(errMsg){
cb(errMsg)
}, {
enableHighAccuracy: true,
timeout: 60*1000*2,
maximumAge: 1000*60*10
});
}, {
enableHighAccuracy: false,
timeout: 10*1000,
maximumAge: 1000*60*10
});
my config.xml:
我的 config.xml：
<feature name="Geolocation">
<param name="android-package" value="org.apache.cordova.geolocation.GeoBroker" />
</feature>

Finally I have solve the problem,now on my android phone, getCurrentPositionfunction return location infomation very quickly every time, I never need reboot my phone again!
I'm not sure wether cordova v3.4.1's geoloation plugin has bugs.
终于我解决了这个问题，现在在我的安卓手机上，getCurrentPosition功能每次都很快返回位置信息，我再也不需要重启手机了！我不确定cordova v3.4.1 的geoloation 插件是否有错误。
The reason to occur this problem is we always to use browser's navigator.geolocation.getCurrentPositionfunction to locate the postion,so we must let app use cordova native implementation instead of html5.
出现这个问题的原因是我们总是使用浏览器的navigator.geolocation.getCurrentPosition功能来定位位置，所以我们必须让app使用cordova原生实现而不是html5。
Here is the the solution with cordova v3.4.1, hope it can help you,in fact it has resolved my question.
这是cordova v3.4.1的解决方案，希望能帮到你，其实已经解决了我的问题。

$ cordova plugin add E:\org.apache.cordova.geolocation
7、run build commond
7、运行build commond
$ cordova build android
8.check if it work fine
8.检查它是否工作正常
check YOUR_APP\plugins\android.jsonmust include:
检查YOUR_APP\plugins\android.json必须包括：

9.run the app
9.运行应用程序
write the geelocation code to get lat and lng:
编写地理定位代码以获取 lat 和 lng：
navigator.geolocation.getCurrentPosition(function(pos){
alert('suc')
alert(JSON.stringify(pos))
},function(errMsg){
alert(JSON.stringify(errMsg))
navigator.geolocation.getCurrentPosition(function(pos){
alert('suc')
alert(JSON.stringify(pos))
},function(errMsg){
alert(JSON.stringify(errMsg))
}, {
enableHighAccuracy: true,
timeout: 60*1000*2,
maximumAge: 1000*60*10
});
}, {
enableHighAccuracy: false,
timeout: 60*1000,
maximumAge: 1000*60*10
});
});
if your phone support use wifi/3G locate then we will get location immediately,else you will see the errMsg timeoutand then geolocationwill use gps to locate postion with native implement.
如果您的手机支持使用 wifi/3G 定位，那么我们将立即获取位置，否则您将看到errMsg timeout然后geolocation使用本机工具使用 GPS 定位位置。
now we get the lat and lng, and never need reboot the android phone agian,thank goodness.
现在我们得到了 lat 和 lng，再也不需要重启安卓手机了，谢天谢地。
if you still have the problem,try to install the plugin to clean the webview cache:
如果问题仍然存在，请尝试安装插件来清理 webview 缓存：
