Java 解包压缩错误

所以当我试图在pc上解压我的zip文件时出现了错误

7zip错误-试图在文件开头之前移动文件指针

UPD-发送到ftp后，在发送存档文件之前发生错误

对于使用ftp，我使用ClientFTP库

首先，在我的设备上，我创建了一个带有gps坐标的文本文件，然后我尝试将其压缩并上传到ftp

然后下载到pc并解压缩

我尝试了许多方法来创建归档

下面的代码创建一个文本文件

 File file;
  try{
    file = new File(path, "locations.lft");
    if (file.exists())
      file.delete();
      file.createNewFile();
    }catch (Exception e){
    try{ftp.quit();}catch(Exception E){}
      return;
    }
   BufferedWriter BW = null;
   try{
BW = new BufferedWriter(new FileWriter(file));
}catch(Exception e){
try{ftp.quit();}catch(Exception E){}
    return;
}
Cursor row = db.Query("locations",null,"date_time BETWEEN " + ToBeggingOfDay(date).getTime() + " AND " + 
                    ToEndOfDay(date).getTime());
try{
   while (row.moveToNext()){
   String line = "" + row.getString(row.getColumnIndex("latitude")) + "~" +  row.getString(row.getColumnIndex("longtitude")) + "~"  + DateFormat.format("yyyy-MM-dd-kk-mm-ss", new Date( row.getLong(row.getColumnIndex("date_time")) )) + "~" + "0~~~~"+row.getString(row.getColumnIndex("speed"));
       BW.write(line);
   BW.newLine();
 }
}catch (Exception e){
SendMsg("ERROR", "Can't write in file (" + e.getLocalizedMessage() + ")");
try{ftp.quit();}catch(Exception E){}
  try{BW.close();}catch(Exception E){}
return;
}finally{
row.close();
try{BW.close();}catch(Exception E){}
 }

packzip文件的代码

范例

                        try {

                           ZipUtil zipper = new ZipUtil();
                            File directoryToZip = new File(path+"locations.lft");
                            String zipFilePath = path + "1.zip";
                            List<File> listFiles = new ArrayList<File>(1);
                            listFiles.add(directoryToZip);

                            zipper.compressFiles(listFiles, zipFilePath);
                        }catch(Exception e){
                             e.printStackTrace();
                        }
                        file = new File(path, "1.zip");

试试看{
ZipUtil拉链=新ZipUtil（）；
File directoryToZip=新文件（路径+“locations.lft”）；
字符串zipFilePath=path+“1.zip”；
List listFiles=new ArrayList（1）；
添加（directoryToZip）；
压缩文件（listFiles，zipFilePath）；
}捕获（例外e）{
e、 printStackTrace（）；
}
file=新文件（路径“1.zip”）；

很抱歉我的英语不好，希望您能了解我为什么会出现此错误

请在通过ftp发送之前尝试解压缩文件。这将有助于确定这是一个压缩问题还是ftp问题。我甚至没有想过！在sendind之前，我可以毫无错误地解包，但问题仍然存在，有什么想法吗？然后错误在ftp上。正在尝试调试同一代码的示例文件。感谢subirkumarsao，问题出现在我的Ftp库中，现在它已经解决了！再次感谢！干杯自我调试万岁。自助是最好的帮助。：）
