Phonegap-如何将.txt文件保存在android mobile的根目录中 [英] Phonegap - How to save .txt file in root directory of android mobile

问题描述

我正在尝试使用phonegap将.txt文件保存在android mobile的根目录中. 我已经安装了这些插件"cordova-plugin-file"和"cordova-plugin-file-transfer".在config.xml文件中，我添加了此首选项.

I m trying to save a .txt file in root directory of android mobile using phonegap. I have installed these plugins 'cordova-plugin-file' and 'cordova-plugin-file-transfer'. In config.xml file i add this preference.

<preference name="AndroidPersistentFileLocation" value="Internal" />

这是我的代码.

<button class="btn-lg btn-success" onclick="saveFile('hello_world.txt', 'This is Dummy Content')">Write File</button>

用于处理点击事件的代码.

Code to handle on click event.

function saveFile(fileName, fileData) {
    // Get access to the file system
    window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, function (fileSystem) {
        // Create the file.
        fileSystem.root.getFile(fileName, {create: true, exclusive: false}, function (entry) {
            // After you save the file, you can access it with this URL
            var myFileUrl = entry.toURL()
            entry.createWriter(function (writer) {
                writer.onwriteend = function (evt) {
                    alert("Successfully saved file to " + myFileUrl)
                }
                // Write to the file
                writer.write(fileData)
            }, function (error) {
                alert("Error: Could not create file writer, " + error.code)
            })
        }, function (error) {
            alert("Error: Could not create file, " + error.code)
        })
    }, function (evt) {
        alert("Error: Could not access file system, " + evt.target.error.code)
    })
}

成功回调后，它将返回此文件位置.

After success callback it return this file location.

file:///data/data/com.adobe.phonegap.app/files/files/hello_world.txt

但是当我尝试在给定位置查找此文件时.它不在那里.我希望此文件位于我的手机根目录中.

But when i try to find this file in given location. Its not there. I want this file in my root directory of mobile.
