工作灯 6.2.0.00-20120814-0824

位置代码在浏览器模拟器中运行良好，但在 Android 模拟器中失败，成功或失败回调均未触发。

Logcat 显示：

10-06 16:00:40.707：W/PluginManager(3193)：线程警告：对 WLGeolocationPlugin.getLocation 的 exec() 调用阻塞了主线程 75 毫秒。插件应该使用 CordovaInterface.getThreadPool()。

代码：

var showPosition = function(position) {
        WL.Logger.debug("got a position");
        var latitude = Number(position.coords.latitude).toFixed(2);
        var longitude = Number(position.coords.longitude).toFixed(2);
        $("#currentLocation").text(latitude + " / " + longitude);

    };

    var positionError = function(err) { 
        WL.Logger.debug("failed to get  a position");
        $("#status").text("position error" + err); 

    };

    var geoPolicy = WL.Device.Geo.Profiles.RoughTracking(); // other profiles tried, same result

    WL.Device.Geo.acquirePosition(showPosition, positionError, geoPolicy);

Android清单有

<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_LOCATION_EXTRA_COMMANDS"/>

在我添加之前，我有不同的错误条件，表明权限错误，所以我认为权限现在是正确的。

我已经部署到真正的 Android 设备，但仍然没有触发回调。我确实在 LogCat 中看到了这些消息，表明 Worklight 正在使用 gps 执行某些操作，但就我的代码而言没有提供答案

答案似乎是我需要指定一个 maximumAge 选项

  var geoPolicy = WL.Device.Geo.Profiles.RoughTracking(); // other profiles tried, same result

  geoPolicy.maximumAge = 5000;

  WL.Device.Geo.acquirePosition(showPosition, positionError, geoPolicy);

日志（如上所示）表明已获得答案，但由于其年龄而被丢弃。似乎我需要指定的 maximumAge 大于获得职位所需的时间。
