Codenameone 奇怪的mkdir（）行为

我的代码运行良好，没有任何麻烦。我真的无法指出是否发生了背景更新，我的代码是否被破坏。我试图在设备上创建目录/文件，但它抛出了一个错误。请参阅下面Logcat的堆栈跟踪和我的代码

您需要一个接一个地创建每个目录，直到找到最后一个。这就是

mkdir

与

mkdirs

相反的工作方式。请发布一个最小、完整且可验证的代码示例。（）您没有使用标准的android工具链。也许你应该标记为代号1以获得答案。谢谢Shai…工作正常。也许在后续更新中可以包含mkdirs（）方法……不幸的是，它并非在所有操作系统上都可用。我同意我也更喜欢这种方法。。。

char sep = FileSystemStorage.getInstance().getFileSystemSeparator();
            String dir = FileSystemStorage.getInstance().getAppHomePath() + sep + "dataplat"+sep+"entries"+sep+code+sep+section+sep+entry;
Display.getInstance().callSerially(new Runnable()
        {
            public void run()
            {
                if(isSilent == false)
                {
                    status.setMessage("Preparing to send...");
                    status.setShowProgressIndicator(true);
                    status.setIcon(createIcon(FontImage.MATERIAL_WORK));
                    status.show();
                    errorCode= "1594";
                }
                char sep = FileSystemStorage.getInstance().getFileSystemSeparator();
                String dir = FileSystemStorage.getInstance().getAppHomePath() + sep + "dataplat"+sep+"entries"+sep+code+sep+section+sep+entry;
                try
                {
                    FileSystemStorage.getInstance().mkdir(dir + sep + "sent"+sep);
                    errorCode= "1595";
             //Line 1771       OutputStream dest = FileSystemStorage.getInstance().openOutputStream(dir + sep + "sent" + sep + "sent.jaji");
                    TarOutputStream out = new TarOutputStream( new BufferedOutputStream( dest ) );
                    String entries[]  = FileSystemStorage.getInstance().listFiles(dir);
