我试图登录到我的Windows服务器中使用JCIFS下载文件。 该应用程序工作正常，在我的Android 2.2手机和一个老2.3的平板电脑。 我刚刚购买了乐潘II我升级到了4.0.3。 当我尝试运行我的应用程序它的崩溃试图访问服务器时。 有没有什么新的东西，我需要为4.0.3呢？ 我试着注释掉属于输出流，以确保它是输入端导致了问题的一切。 如果我注释掉里面的东西最里面的try块一切工作正常，所以它的东西在里面。 只要我去掉的InputStream在= file.getInputStream（）; 然后崩溃。

权限清单文件。 

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="15" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<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"/>
<uses-permission android:name="android.permission.WRITE_MEDIA_STORAGE"/>

下载功能

public static String DlFile() {
    SmbFile file = null;
    try {
        file = new SmbFile("smb://NAME:PASSWORD@10.0.0.4/jws/Data/Inspection Reports/forms/0990125.txt");

        Log.v(TAG, "smbFile: " + file.toString());
        try {
                InputStream in = file.getInputStream();
                FileOutputStream out = new FileOutputStream(cfgSDFolder + myFile);
                byte[] b = new byte[8192];
                int n;
                while(( n = in.read( b )) > 0 ) {
                    out.write( b, 0, n );
                }
                in.close();
                out.close();    
        } catch (Exception e) {
            e.printStackTrace(); 
            Log.v(TAG, "DSZerror: " + e.getMessage().toString());
            return "error: " + e.getMessage().toString();
        }
    } catch (MalformedURLException e) {
        e.printStackTrace();
        Log.v(TAG, "DSZerror:" + e.getMessage().toString());
        return "error: " + e.getMessage().toString();
    } // note the different format  
    return "ok";

}
