 private static final int SELECT_PICTURE = 1;
 private String selectedImagePath;
TextView messageText;
Button uploadButton;
int serverResponseCode = 0;
ProgressDialog dialog = null;
String upLoadServerUri = null;
final String uploadFilePath =  Environment.getExternalStorageDirectory().getPath();
//final String uploadFileName = "";
private Button buttonLoadImage;
private ImageView img;
@Override
public void onCreate(Bundle savedInstanceState) {

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

    img = (ImageView)findViewById(R.id.imgView);

    buttonLoadImage = (Button) findViewById(R.id.buttonLoadPicture);
    buttonLoadImage.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View arg0) {

             Intent intent = new Intent();
             intent.setType("image/*");
             intent.setAction(Intent.ACTION_GET_CONTENT);
             startActivityForResult(Intent.createChooser(intent,"Select Picture"), SELECT_PICTURE);
        }
    });
    uploadButton = (Button)findViewById(R.id.uploadButton);

          return serverResponseCode; 

       } // End else block 
     } 
  }

How can I fix that?


Solution

  • dont hard code the file location, use like this:

    String uploadFilePath=Environment.getExternalStorageDirectory().getAbsolutePath()+"/windows/PublicPictures/SamplePictures/";
    

    try to check the file is exist or not like this:

                File file = new File(picturePath);
                if(file.exists()){
                    //write your uploading functionality here.
                }else{
                    //file not found please select another file.
                }
    

    in your on activity result method change like this:

    @Override
        protected void onActivityResult(int requestCode, int resultCode, Intent data) {
            // TODO Auto-generated method stub
            if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK
                    && null != data) {
                Uri selectedImage = data.getData();
                String[] filePathColumn = { MediaStore.Images.Media.DATA };
    
                Cursor cursor = getContentResolver().query(selectedImage,
                        filePathColumn, null, null, null);
                cursor.moveToFirst();
    
                int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
                String picturePath = cursor.getString(columnIndex);
                cursor.close();
    
                File file = new File(picturePath);
                if (file.exists()) {
                    uploadFileName=picturePath;
                }
    
                ImageView imageView = (ImageView) findViewById(R.id.imgView);
                imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));
            }
        }
    

    and this also:

    uploadButton.setOnClickListener(new OnClickListener() {
                @Override
                public void onClick(View v) {
    
                    dialog = ProgressDialog.show(UploadToServer.this, "",
                            "Uploading file...", true);
    
                    new Thread(new Runnable() {
                        public void run() {
                            runOnUiThread(new Runnable() {
                                public void run() {
                                    messageText.setText("uploading started.....");
                                }
                            });
    
                            uploadFile(uploadFileName);
                        }
                    }).start();
                }
            });
