Upload Picture on FTP Server from Android

This post is very useful to novice users and users facing various problems on uploading picture from android to ftp server. This is very simple and straight forward post and I assumed you have good understanding of android basics. This time I won't start from scratch (i.e. from creating new android project), instead I assumed that you have already created android project with an activity and main.xml (UI).  Please follow the simple steps as given below.

Step#1:
//declare the following in your activity before onCreate Method

      
      private RelativeLayout photos_layout;
      private static Bitmap scaledphoto=null;

      private String filePath=null;

      private Uri u=null;

      private Boolean picTaken=false;

    

Step#2: 

In onCreate Method of your activity, write this code:

      @Override

      protected void onCreate(Bundle savedInstanceState) {

           

            super.onCreate(savedInstanceState);
            setContentView(R.layout.main);

photos_layout=(RelativeLayout)findViewById(R.id.photos); 

            //button with onClickListener to turn on camera for taking picture

            ((Button)photos_layout.findViewById(R.id.capture_photo))

            .setOnClickListener(new View.OnClickListener() {     

     

                  @Override                 

                  public void onClick(View arg0) {

                       

                        String pictureName="Test";//here you can get picture name from user. I supposed Test name

                        Intent intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);

                        File photo = new File(Environment.getExternalStorageDirectory(),  pictureName+".jpg");//save picture (.jpg) on SD Card

                        u=Uri.fromFile(photo);

                        intent.putExtra(MediaStore.EXTRA_OUTPUT,u);      

                        filePath = photo.getAbsolutePath();        

                        startActivityForResult(intent, REQUEST_CODE);

                  }

            }

           

            ((Button)photos_layout.findViewById(R.id.upload_picture))

            .setOnClickListener(new View.OnClickListener() {     

     

                  @Override                 

                  public void onClick(View arg0) {

                       

                        upLoadPicture();

                  }

            }

      }

Step#3:

Now in onActivityResult Method, copy/write this code:

protected void onActivityResult(int requestCode, int resultCode, Intent data) {

super.onActivityResult(requestCode, resultCode, data);

 

 try {

             getContentResolver().notifyChange(u, null);  

             ContentResolver cr = getContentResolver();     

             Bitmap bm = android.provider.MediaStore.Images.Media.getBitmap(cr, u);

//ImageView to set the picture taken from camera.

             photo_captured=(ImageView)photos_layout.findViewById(R.id.pic_captured);

             photo_captured.setImageBitmap(bm);      

             picTaken=true; //to ensure picture is taken 

      }catch(Exception e) {

           

       e.printStackTrace();   

     

     }                            

}

Step#4:

After picture is taken, than implement the upload method as under:

//Method for uploading picture on FtpServer

public void upLoadPicture() {

      if(picTaken){

        

            final ProgressDialog pd = ProgressDialog.show(UserInfoActivity.this, "Please wait", "Uploading Picture ...", true);

            new Thread(){    

                       

                  @Override        

                  public void run() {              

                 

                        File file = new File(filePath);  

                             

                              try {

                                   

                                    FTPClient client = new FTPClient();

                                    client.connect("ftp.********.net");

                                    client.login(ftp_server_username, ftp_server_password); //this is the login credentials of your ftpserver. Ensure to use valid username and password otherwise it throws exception

           

                                    try {

                                         

                                          client.changeDirectory("MyPictures"); //I want to upload picture in MyPictures directory/folder. you can use your own.

                                    } catch (Exception e) {

                                         

                                          client.createDirectory("MyPictures");

                                          client.changeDirectory("MyPictures");

                                    }  

                                    client.upload(file); //this is actual file uploading on FtpServer in specified directory/folder

                                    client.disconnect(true);   //after file upload, don't forget to disconnect from FtpServer.                    

                                    file.delete();

                              }                                              

                              catch (Exception e) {

                                    Toast.makeText(getApplicationContext(), "Exception: "+e.getMessage(), Toast.LENGTH_LONG).show();   

                              }                            

                        }

                        pd.dismiss();          

                  }          

           

            }.start();       

     

            }

            else

            {

                  Toast.makeText(getApplicationContext(), "Please Take Picture First than Upload.", Toast.LENGTH_LONG).show();     

                                         

            }

}

Picture uploading on Ftp Server is done. Similarly, you can upload any file on ftpserver as well.

Please don't forget to ask if you are facing difficulty in implementing this post. Your valuable suggestions are highly appreciated and please correct me if I am doing something wrong in this post.
