XML 在 Android 上不显示

Question

我创建了一个天气数据查询。数据以 xml 形式加载。 在 Adob​​e Animate 中测试场景时，将加载所有数据。

当生成的apk文件安装在android手机上时，没有加载任何数据

villach.addEventListener(MouseEvent.CLICK, clickHandler_vf);
function clickHandler_vf(event: MouseEvent): void {
gotoAndStop(2)
wetter_header.ort_name.text = "Villach"
var wetterloader: URLLoader = new URLLoader();
var wetterrequest: URLRequest = new URLRequest("http://api.weatherapi.com/v1/forecast.xml?key=XXXXX&q=Villach&days=1&aqi=no&alerts=no");
wetterrequest.method = URLRequestMethod.POST;
wetterloader.load(wetterrequest);
wetterloader.addEventListener(Event.COMPLETE, completeHandlerwetter);
function completeHandlerwetter(event: Event): void {
    var xml: XML = XML(wetterloader.data);
    var aktual = xml.current.last_updated;
    var derzeit_temp = xml.current.temp_c
    var max_temp = xml.forecast.forecastday.day.maxtemp_c
    var min_temp = xml.forecast.forecastday.day.mintemp_c
    var wind_max = xml.forecast.forecastday.day.maxwind_kph
    var uv_max = xml.forecast.forecastday.day.uv
    var wettericon = "http:" + xml.forecast.forecastday.day.condition.icon
    wetter_header.version.text = aktual
    temp_derzeit.anzeige.text = derzeit_temp + "ºC"
    temp_max.anzeige.text = max_temp + "ºC"
    temp_min.anzeige.text = min_temp + "ºC"
    wind.anzeige.text = wind_max + " km/h"
    uv.anzeige.text = uv_max
    picloader.source = wettericon
}
}
