引发了意图，但操作仅在调试模式下完成

我正在开发一个应用程序，一旦无线连接可用，该应用程序会将数据上传到FTP服务器。 问题是，仅当我处于调试模式时才上传数据。 

            if (sharedpreferences.getBoolean("autoupload",false)){
                // Do your work.
                String directory = context.getFilesDir().getAbsolutePath() + File.separator + "Messdaten";
                File f = new File(directory);
                File[] files = f.listFiles();
                if (files.length != 0 ){
                    for (int i = 0; i < files.length; i++) {
                        String filepath = files[i].toString();
                        FTPupload FTPu = new FTPupload(filepath);
                        FTPu.execute();
                        Toast.makeText(context, "BikeLog Daten werden hochgeladen", Toast.LENGTH_SHORT).show();
                    }
                } 
            }

显示了Toast消息，所以我确信，其他所有内容也应达到。但是，当我通过设备资源管理器检查数据时，它仍然存在，尽管应该在上传后将其删除。

class FTPupload extends AsyncTask<Void, Void, String> {
    String path;
    ProgressDialog uploading;

    public FTPupload(String filepath) {
        path = filepath;
    }

    @Override
    protected String doInBackground(Void... params) {
        FTPSClient con = null;

        try {
            con = new FTPSClient();
            con.connect("XXXXXXXX");

            if (con.login("XXXXXXXXXX", "XXXXXXXXXXX")) {
                con.enterLocalPassiveMode(); // important!
                con.setFileType(FTP.BINARY_FILE_TYPE);
                FileInputStream in = new FileInputStream(new File(path));
                String filename = path.substring(path.lastIndexOf("/") + 1);
                boolean result = con.storeFile(filename, in);

                in.close();
                if (result) {
                    Log.v("upload result", "succeeded");
                    File file = new File(path);
                    boolean deleted = file.delete();
                }
                con.logout();
                con.disconnect();
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
        return path;
    }
}

疯狂的事情是，一旦我将其插入计算机并在FTP连接中设置了断点，一切都会按计划进行，然后将数据发送到服务器。

您能帮我弄清楚哪里出了问题吗？任何提示都很棒！

答案 0 :(得分：0)

这可能是计时问题。在调试模式下，所有操作都会变慢，并且如果您有断点，则执行将在断点处停止。这可能会给其他线程一些时间来做其他事情，这隐藏了问题。从logcat看来，设备无法访问您的服务器。错误“ UnknownHostException”表示“ webhosting31.1blu.de”的DNS解析未返回IP地址。这意味着您没有连接到Internet，或者DNS配置已损坏。

如果您认为这是某种计时问题，则可以在尝试上传数据之前添加一些延迟，或者可以添加一些重试功能，该功能会稍等片刻，然后在上传失败时再次尝试。
