    public static String postFile(String url,String fileName, String userName) throws Exception {

    HttpClient client = new DefaultHttpClient();

对于复制的文件错误，请使用：

packagingOptions {
    exclude 'META-INF/DEPENDENCIES.txt'
    exclude 'META-INF/LICENSE.txt'
    exclude 'META-INF/NOTICE.txt'
    exclude 'META-INF/NOTICE'
    exclude 'META-INF/LICENSE'
    exclude 'META-INF/DEPENDENCIES'
    exclude 'META-INF/notice.txt'
    exclude 'META-INF/license.txt'
    exclude 'META-INF/dependencies.txt'
}

它不仅可以用Apache的libs解决许多“重复文件”，而且可以忽略依赖项错误。
