使用JCIFS向Windows共享写入权限错误

Question

我正在编写一个简单的应用程序来将文件复制到本地Windows网络上的一个共享中，但是在执行代码时会发现下面的错误。我正在使用JCIFS库和SmbFileOutputStream。

目标共享和文件夹为每个人设置了完全的控制权限(它位于Windows 2008服务器上)。我还在Windows 7工作站上尝试了一个共享文件夹，但也得到了相同的错误。下面是我的Android清单中的代码和权限。我为该应用程序启用了以下权限: ACCESS_NETWORK_STATE、ACCESS_WIFI_STATE、INTERNET

class CopySMBFile extends AsyncTask<String, String, String> {
    @Override
    protected void onPreExecute() {
        super.onPreExecute();
    }
    @Override
    protected String doInBackground(String... f_url) {
        try {
            String fileContent = "This is a test file";
            try{
                String user = "myusername:mypassword";
                System.out.println("User: " + user);

                NtlmPasswordAuthentication auth = new NtlmPasswordAuthentication(user);
                String path = "smb://192.168.1.4/k/temp/fileName.txt";
                System.out.println("Path: " +path);

                SmbFile sFile = new SmbFile(path, auth);
                SmbFileOutputStream sfos = new SmbFileOutputStream(sFile);
                sfos.write(fileContent.getBytes());

                System.out.println("Finished attempt to write file");
            } catch (Exception e) {
                e.printStackTrace();
            }
        } catch (Exception e) {
            e.printStackTrace();
            Log.e("Connected", e.getMessage());
        }

        return null;
    }

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name=".MainActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
    <uses-permission android:name="android.permission.INTERNET"/>
</application>

​

对于如何解决(或进一步诊断)这个问题，有什么想法吗？

Answer 1

将<uses-permission>元素移动为<application>的对等元素，而不是<application>的子元素。
