I'm working on an Android project that requires FTP download to be paused/resumed.

Here is the code I use for FTP connection:

```
ftpClient.setConnectTimeout(25000);
ftpClient.login("login", "password");
ftpClient.changeWorkingDirectory("/audio");
ftpClient.enterLocalPassiveMode();
ftpClient.setFileType(FTP.BINARY_FILE_TYPE);

```

then I start download:

```
OutputStream outputStream = new BufferedOutputStream(new FileOutputStream(localFile));

byte[] bytesArray = new byte[4096];
int bytesRead = -1;
totalRead = 0;

if (localFileSize > 0) {
    ftpClient.setRestartOffset(localFileSize);
    ftpClient.restart(localFileSize);
}

InputStream inputStream = ftpClient.retrieveFileStream(fileName);

while ((bytesRead = inputStream.read(bytesArray)) != -1) {
    totalRead += bytesRead;
    outputStream.write(bytesArray, (int) localFileSize, bytesRead);
}

success = ftpClient.completePendingCommand();

```

and I try to pause using `abort` like this: 

```
if (ftpClient.abort()) {
   //connection aborted!;
}

```

But it seems that `abort` doesn't work while there is an active download as mentioned here: <https://issues.apache.org/jira/browse/NET-419>

**Is there any way I can perform pause/resume for FTP downloads in Android?**
