Question

我使用apache commons将图像上传到Web托管服务器。

我使用AsyncTask并且它似乎卡在storeFile（），我的copyStreamListener似乎太早完成但后来什么也没做？该方法的其余部分未执行，上传的文件仅部分上传到我们的服务器上（大约30％的图像可见）。 FTP回复代码都可以，但它不会关闭连接或完成asynctask

BUT

我已经在8台设备上测试了它，它只影响其中的3台，而不是所有的时间！有问题的设备都在Android 7.0（Nougat）上运行，也许它与它有关？

我不认为代码存在问题（因为它在大多数设备上都很好）但是这里是如何上传

 FTPClient ftp = new FTPClient();
    try {
        ftp.connect(InetAddress.getByName("my.host"));

        if (ftp.login("user", "pass")) {
            Log.i("Server", " --- FTP Logged In --- ");

            ftp.enterLocalPassiveMode(); 
            ftp.setFileType(FTP.BINARY_FILE_TYPE);
            String directory = "/user" + String.valueOf(userID);
            ftp.makeDirectory(directory);
            ftp.changeWorkingDirectory(directory);

            for (int i = 0; i < imageFilePaths.size(); i++) {
                    uploadFile(imageFilePaths.get(i), ftp, directory);                
                }

            ftp.logout();
            ftp.disconnect();

            Log.i("Server", " --- Logged out --- ");

        }
    } catch (IOException e) {
        e.printStackTrace();
    }




 private void uploadFile(ImageFiles imageFilePaths, FTPClient ftp, String directory) {


    try {

            final File finalFile = new File(imageFilePaths.fullPath);
            final long fileSize = finalFile.length();
            final String filename = String.valueOf(System.currentTimeMillis());

            BufferedInputStream buffIn = new BufferedInputStream(new FileInputStream(finalFile));
            streamListener = new CopyStreamAdapter() {

                @Override
                public void bytesTransferred(long totalBytesTransferred,
                                             int bytesTransferred, long streamSize) {
                    totalFileSizeTrasnfered = totalFileSizeTrasnfered + bytesTransferred;
                    updateProgress();
                    if (totalBytesTransferred == fileSize) {
                        removeCopyStreamListener(streamListener);
                    }
                }
            };
            ftp.setCopyStreamListener(streamListener);

            // excecution seems to stop here
            boolean result = ftp.storeFile(filename + imageFilePaths.fileExt, buffIn);
            Log.i("Server", " --- File uploaded --- " + result);

           buffIn.close();



        }
    } catch (IOException e) {
        e.printStackTrace();
    }
}

登录后在logcat中显示的所有内容都是......

否＆＃34;退出＆＃34;或＆＃34;文件已上传＆＃34;并且应用程序继续运行。

任何人都可以给我任何有关如何解决或指向正确方向的见解吗？谢谢

FTP在图像上传期间停止，而不是执行过去的storeFile（）
