Phonegap 地理定位有时无法在 android 上运行

如下编辑 plugin.xml 文件:

edit the plugin.xml file like below:

... ...
<name>Geolocation</name>
<description>Cordova Geolocation Plugin</description>
<license>Apache 2.0</license>
<keywords>cordova,geolocation</keywords>
<repo>https://git-wip-us.apache.org/repos/asf/cordova-plugin-geolocation.git</repo>
<issue>https://issues.apache.org/jira/browse/CB/component/12320638</issue>

        <uses-permission android:name="android.permission.ACCESS_LOCATION_EXTRA_COMMANDS" />
    </config-file>

</platform>

 <!-- amazon-fireos change to android-->
<platform name="android">

</platform>

<!-- ios -->
<platform name="ios">

6.再次添加插件

$ cordova plugin add E:org.apache.cordova.geolocation

7、运行build commond

7、run build commond

$ cordova build android

8.检查是否正常

检查 YOUR_APPpluginsandroid.json 必须包括:

{
   "xml": "<feature name="Geolocation"><param name="android-package" value="org.apache.cordova.geolocation.GeoBroker" /></feature>",
   "count": 1
},
... ...
{
  "xml": "<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />",
  "count": 4
},
{
   "xml": "<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />",
    "count": 4
},
{
  "xml": "<uses-permission android:name="android.permission.ACCESS_LOCATION_EXTRA_COMMANDS" />",
  "count": 1
 }

检查 YOUR_APPplatformsandroidAndroidManifest.xml 必须包括:

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_LOCATION_EXTRA_COMMANDS" />

检查 YOUR_APPplatformsandroid esxmlconfig.xml 必须包括:

<feature name="Geolocation">
    <param name="android-package" value="org.apache.cordova.geolocation.GeoBroker" />
</feature>

9.运行应用程序

编写地理定位代码以获取 lat 和 lng:

write the geelocation code to get lat and 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

});

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 超时，然后 geolocation 将使用 gps 定位位置本机实现.

if your phone support use wifi/3G locate then we will get location immediately,else you will see the errMsg timeout and then geolocation will use gps to locate postion with native implement.

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.

now we get the lat and lng, and never need reboot the android phone agian,thank goodness.

如果还是有问题，尝试安装插件清理webview缓存:

if you still have the problem,try to install the plugin to clean the webview cache:
