Question

我是phonegap的新手，我正在测试一个教程中的android示例代码，每当我调用window.requestFileSystem（LocalFileSystem.TEMPORARY，0，onFileSystemSuccess，fail）时，我没有得到onFileSystemSuccess的回调函数的任何响应或失败，我运行我的Android模拟器时唯一看到的是html设计，我使用api 19版使用phonegap 3.5.0版我真的很感激任何提供的帮助。这是代码..

    fileSystem.root.getFile("readme.txt",{ create: true, exclusive: false}, null, fail);

    var directoryReader = fileSystem.root.createReader();
    directoryReader.readEntries(success,fail);

}
function success(entries){

    var i;

我还在他们的网站上提供了正确的权限，并提供了正确的权限...这里是我的androidmanifest.xml文件

<?xml version='1.0' encoding='utf-8'?>
<manifest android:hardwareAccelerated="true" android:versionCode="1" android:versionName="0.0.1" android:windowSoftInputMode="adjustPan" package="io.cordova.hellocordova" xmlns:android="http://schemas.android.com/apk/res/android">
