android - Cordova 5.0.0 上的地理定位插件总是返回超时过期错误

Question

我已经使用这些插件安装了 Cordova 5.0.0:

cordova插件列表

cordova-plugin-device 1.0.1-dev "Device"
cordova-plugin-geolocation 1.0.0 "Geolocation"
cordova-plugin-globalization 1.0.0 "Globalization"
cordova-plugin-inappbrowser 1.0.1-dev "InAppBrowser"
cordova-plugin-network-information 1.0.0 "Network Information"
cordova-plugin-whitelist 1.0.1-dev "Whitelist"

在任何安卓虚拟设备上运行这段代码:

onDeviceReady: function () {

    var onSuccess = function(position) {
        alert('Latitude: '          + position.coords.latitude          + '\n' +
              'Longitude: '         + position.coords.longitude         + '\n' +
              'Altitude: '          + position.coords.altitude          + '\n' +
              'Accuracy: '          + position.coords.accuracy          + '\n' +
              'Altitude Accuracy: ' + position.coords.altitudeAccuracy  + '\n' +
              'Heading: '           + position.coords.heading           + '\n' +
              'Speed: '             + position.coords.speed             + '\n' +
              'Timestamp: '         + position.timestamp                + '\n');
    };

    // onError Callback receives a PositionError object
    function onError(error) {
        alert('code: '    + error.code    + '\n' +
              'message: ' + error.message + '\n');
    }
    var options = { maximumAge: 3000, timeout: 5000, enableHighAccuracy: true };
    navigator.geolocation.getCurrentPosition(onSuccess, onError, options);
}

返回:

为什么总是返回超时过期？

这听起来很愚蠢，但是，您是否激活了手机中的“GPS”选项？
