我正在开发一个Android应用程序，我需要将我的图像发送到特定的FTP URL地址，任何人都可以帮助我，我该怎么办呢。

我的代码是：
public class ImageGallery extends Activity
{
private static final int PICK_IMAGE = 1;
private static final int PICK_Camera_IMAGE = 2;
private ImageView imgView;
private Button upload,cancel;
private Bitmap bitmap;
private ProgressDialog dialog;
Uri imageUri;
Uri selectedImageUri = null;
String filePath = null;
MediaPlayer mp=new MediaPlayer();
Handler progressHandler = new Handler();
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_image_gallery);
imgView = (ImageView) findViewById(R.id.ImageView);
upload = (Button) findViewById(R.id.imguploadbtn);
cancel = (Button) findViewById(R.id.imgcancelbtn);
upload.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v)
{
if (bitmap == null)
{
Toast.makeText(getApplicationContext(),"Please select image", Toast.LENGTH_SHORT).show();
}
else
{
dialog = ProgressDialog.show(ImageGallery.this, "Uploading","Please wait...", true);
new ImageGalleryTask().execute();
}
}
});
cancel.setOnClickListener(new OnClickListener()
{
public void onClick(View v)
{
// TODO Auto-generated method stub
ImageGallery.this.finish();
}
});
}

当我使用此代码并单击上传按钮时 我收到以下错误：
Could not find class 'org.apache.commons.net.ftp.FTPClient', referenced from method com.androidmyway.demo.imagedemo.ImageGallery$ImageGalleryTask.doInBackground

您必须添加使用FTPClient类的依赖项。您可以在任何地方轻松找到它。它是“commons apache”，命名为依赖。
