我想使用FTP协议将图像文件从我的Android设备的存储卡上传到我的主机服务器。但在测试运行期间,我得到一个我无法解决的错误。期待别人帮助我。
源代码
public class FTP extends Activity implements OnClickListener {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_ftp);
Button upload=(Button)findViewById(R.id.button1);
upload.setOnClickListener(this);
}
public void goforIt(){
FTPClient con = null;
try
{
con = new FTPClient();
con.connect("longvan.webatu.com");
if (con.login("a4602996", "25251325thanhtung"))
{
con.enterLocalPassiveMode(); // important!
con.setFileType(FTPClient.BINARY_FILE_TYPE);
String data = "/sdcard/paint/takeshi.jpg";
FileInputStream in = new FileInputStream(new File(data));
boolean result = con.storeFile("/paint/takeshi.jpg", in);
in.close();
if (result) Log.v("upload result", "succeeded");
con.logout();
con.disconnect();
Toast.makeText(this, "Tai len thanh cong!", Toast.LENGTH_LONG).show();
}
else
{
Toast.makeText(this, "Ket noi that bai!", Toast.LENGTH_LONG).show();
}
}
catch (Exception e)
{
e.printStackTrace();
}
}
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
switch (arg0.getId()) {
case R.id.button1:
goforIt();
break;
default:
break;
}
}
}
