Meteor的cordova：geolocation插件不能在手机上工作 [英] Meteor's cordova: geolocation plugin doesn't work on mobile

问题描述

我将Meteor（1.2.0.2）应用程式部署到Android装置。

我是以

安装插件

  meteor add cordova：cordova-plugin-geolocation@1.0.0 
  

b $ b

添加Cordova插件cordova-plugin-geolocation@1.0.0。

I使用的插件：

  document.addEventListener（deviceready，onDeviceReady，false）; 
 function onDeviceReady（）{
 navigator.geolocation.getCurrentPosition（function（p）{// onSuccess 
 console.log（p）; 
}，function（e）{
 console.log（e）; 
}）; 
} 
  

在桌面上完美地打印（打印p作为Geolocation对象）忽略回调（包括成功和错误）。

我通过设置断点在Chrome DevTools（ chrome：// inspect 它会一直到.getCurrentPosition调用，然后（跳过或步进）只是跳过这两个回调（如果我在其中设置一个断点，他们只是没有命中）。

我甚至尝试过

  navigator.geolocation.getCurrentPosition（function（p）{console.log（p）; 
 
 
 >  undefined 
地理位置{...} 
  
 不工作）
 未定义
 //不打印其他内容
  
可能与应用程式的权限有关吗？
 
 
 
  EDIT ：我已验证 AndroidManifest.xml ，且权限实际上由插件设置：
 < uses-permission android：name =android.permission.ACCESS_COARSE_LOCATION/> 
< uses-permission android：name =android.permission.ACCESS_FINE_LOCATION/> 
  
 
 
解决方案
 @dragonmnl，
 
 
 
 
  GPS不可靠。
 
 
 
你没有谈论超时，我必须假设你没有设置超时足够长。尝试将其设置为约20秒 - 至少。 
 
 
 
如果您的阅读不佳，或者您已逾时
 
 
 
 
 
 
 
 
确保您清楚地查看所有视野（无阻挡视图）
 
 
走在一个大圆，直径约15英尺
 
 
 
 
 
在大约30-45秒内，你应该有一个阅读。 
当你阅读我给你的链接时，这将是有意义的。

I'm deploying my Meteor (1.2.0.2) app to an Android device.

I installed the plugin by
 meteor add cordova:cordova-plugin-geolocation@1.0.0



  
Added Cordova plugin cordova-plugin-geolocation@1.0.0.
I used the plugin by:
    document.addEventListener("deviceready", onDeviceReady, false);
    function onDeviceReady() {
        navigator.geolocation.getCurrentPosition(function(p){ // onSuccess
            console.log(p);
        }, function(e){
            console.log(e);
        });
    }
On desktop works perfectly (print p as Geolocation object) but on mobile it just ignores the callbacks (both success and errors).

I tested it in Chrome DevTools (chrome://inspect) by setting breakpoints. It steps until .getCurrentPosition call but then (either step over or step in) just skips both callbacks (and If I set a breakpoint within them, they are just not hit).

I even tried
navigator.geolocation.getCurrentPosition(function(p){ console.log(p); 
both on Desktop console (works)
undefined
Geolocation { ... }
and mobile (does not work)
undefined
// nothing else is printed
Maybe has it something to do with app's permissions?

EDIT: I verified AndroidManifest.xml and the permissions are actually set by the plugin:
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

解决方案
@dragonmnl,


GPS is unreliable.

You did not talk about timeout, I must assume you have NOT set the timeout long enough. Try setting it to about 20 seconds -- as a minimum. 

If your readings are poor, or you are timing out


go outside
make sure you have a clear view of all horizons (nothing blocking the view)
walk in a big circle, about 15ft in diameter


In about 30-45 seconds you should have a reading.
This will make sense when you read the link I gave you.
