Worklight 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,既没有成功也没有失败回调。
Logcat显示:
10-06 16:00:40.707:W / PluginManager(3193):THREAD WARNING:exec()调用WLGeolocationPlugin.getLocation阻塞主线程75ms。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
<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。
-------编辑添加更多信息----
我已部署到真正的Android设备但仍未获得回调。我确实在LogCat中看到了这些消息,表明Worklight正在使用gps做一些事情,但到目前为止我的代码并没有提供答案

答案 0 :(得分:4)
答案似乎是我需要指定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)表示获得了答案,但根据其年龄被丢弃。似乎我需要指定maximumAge大于获得位置所需的时间。
