Android - Image upload to .net Web service Error

Question

I have created the following code to connect to a .net Web Service API and upload a image. I am however presented with an error. Can someone please explain how this can be resolved?

 private static int RESULT_LOAD_IMAGE = 1;
 Button imageLoad, uploadBtn;
 ImageView imageView;
 TextView imagePath, message;
 String imgPath;
 private Bitmap bitmap;
 private ProgressDialog dialog;

 @Override
 protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    imageLoad = (Button) findViewById(R.id.buttonLoadPicture);
    uploadBtn = (Button) findViewById(R.id.upload);
    imageView = (ImageView) findViewById(R.id.imgView);
    imagePath = (TextView) findViewById(R.id.imagePath);
    message = (TextView) findViewById(R.id.message);

    imageLoad.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {               
            Intent i = new Intent(
                    Intent.ACTION_PICK,
   android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);

            startActivityForResult(i, RESULT_LOAD_IMAGE);               

        }
    });

    uploadBtn.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {

            dialog = ProgressDialog.show(MainActivity.this, "", "Uploading 
      file...", true);
            new uploadFile().execute();
        }
    });
 }

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

    if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data) {
        Uri selectedImage = data.getData();
        Log.d("Selected image URI", selectedImage.toString());

        String[] filePathColumn = { MediaStore.Images.Media.DATA };
        Log.d("Image Path Column", filePathColumn.toString());

        Cursor cursor = getContentResolver().query(selectedImage,
                filePathColumn, null, null, null);
        cursor.moveToFirst();

        int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
        String picturePath = cursor.getString(columnIndex);
        cursor.close();
        Log.d("Picture Path", picturePath);
        imagePath.setText(picturePath);
        imgPath = picturePath;
        ImageView imageView = (ImageView) findViewById(R.id.imgView);
        imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));

    }
 }


 class uploadFile extends AsyncTask<Void, Void, String> {

    @Override
    protected String doInBackground(Void... params) {

        Bitmap bm = BitmapFactory.decodeFile(imgPath);
        ByteArrayOutputStream baos = new ByteArrayOutputStream();  
        bm.compress(Bitmap.CompressFormat.PNG, 100, baos);
        byte[] b = baos.toByteArray();

        Log.d("b", b.toString());
        Log.d("baos", baos.toString());


        SoapObject request = new SoapObject("http://tempuri.org/", "sendImage");        
        request.addProperty("myImage", b);

        SoapSerializationEnvelope envelope=new   
     SoapSerializationEnvelope(SoapEnvelope.VER11);
        new MarshalBase64().register(envelope);
        envelope.dotNet = true; 
        envelope.setOutputSoapObject(request);

        try {
            Toast.makeText(getApplicationContext(), "Sending Pic", 
                       Toast.LENGTH_LONG).show();
            Toast.makeText(getApplicationContext(), "array length=" + b.length, 
                              Toast.LENGTH_LONG).show();
            HttpTransportSE androidHttpTransport = new 
                  HttpTransportSE("http://www.letstrend.com/spursService.asmx?WSDL");
            androidHttpTransport.call("http://tempuri.org/sendImage", envelope);
            SoapObject result = (SoapObject)envelope.bodyIn;
            Log.d("Soap Response", result.toString());
        } catch (Exception e) {
            e.printStackTrace();            
            Toast.makeText(getApplicationContext(), "in catch e=" + e.getMessage(), 
                  Toast.LENGTH_LONG).show();
            Toast.makeText(getApplicationContext(), "fault=" + ((SoapFault) 
                  envelope.bodyIn).faultstring, Toast.LENGTH_LONG).show();
        }

        return null;
    }

 }

Do not acces your UI-Thread from AsyncTask, your Toast tries to acces it. So please make all UI-Thread Actions in the onPostExecute and overgive this method something to work with, eg. an Object with your Bitmap and some string with a error.

//DEFINE TO RETURN A SOAP OBJECT
class uploadFile extends AsyncTask<Void, Void, SoapObject> {


//DEFINE TO RETURN A SOAP OBJECT
@Override
protected SoapObject doInBackground(Void... params) {

    Bitmap bm = BitmapFactory.decodeFile(imgPath);
    ByteArrayOutputStream baos = new ByteArrayOutputStream();  
    bm.compress(Bitmap.CompressFormat.PNG, 100, baos);
    byte[] b = baos.toByteArray();

    Log.d("b", b.toString());
    Log.d("baos", baos.toString());


    SoapObject request = new SoapObject("http://tempuri.org/", "sendImage");        
    request.addProperty("myImage", b);

    SoapSerializationEnvelope envelope=new   
    SoapSerializationEnvelope(SoapEnvelope.VER11);
    new MarshalBase64().register(envelope);
    envelope.dotNet = true; 
    envelope.setOutputSoapObject(request);

    try {
    // ---> THIS IS BAD!!!!
        Toast.makeText(getApplicationContext(), "Sending Pic", 
                   Toast.LENGTH_LONG).show();
        Toast.makeText(getApplicationContext(), "array length=" + b.length, 
                          Toast.LENGTH_LONG).show();
   //<------- DELETE IT

        HttpTransportSE androidHttpTransport = new 
              HttpTransportSE("http://www.letstrend.com/spursService.asmx?WSDL");
        androidHttpTransport.call("http://tempuri.org/sendImage", envelope);
        SoapObject result = (SoapObject)envelope.bodyIn;
        Log.d("Soap Response", result.toString());
    } catch (Exception e) {
        e.printStackTrace();  

// ---> THIS IS BAD!!!!      
        Toast.makeText(getApplicationContext(), "in catch e=" + e.getMessage(), 
              Toast.LENGTH_LONG).show();
        Toast.makeText(getApplicationContext(), "fault=" + ((SoapFault) 
              envelope.bodyIn).faultstring, Toast.LENGTH_LONG).show();
//<------- DELETE IT

    }
    //TRY TO RETURN A MORE PROPRIATE OBJECT LIKE YOUR RESULT! AND HANDLE IT IN onPostExecute
    return result ;
}

@Override
onPostExecute(SoapObject result){

     if(result == null){
         Toast.makeText(_context, "Something went wrong", Toast.LENGTH_SHORT).show();
         return;
     }
     //HANDLE YOUR RESULT HERE

}

Hi, A.S. Thanks for your reply. Can you please correct the coding and send me back. I don't understand what you said...

A.S. Over a year ago

Made you a code, but please look out for a Android book, it has no sense to only copy it, becouse the next time you are going to use it you have no idea what to do!

MKD Over a year ago

Thank you so much A.S. I am just a newbee. I'll study the android book as you adviced...

MKD Over a year ago

sorry for the delay A.S.

Pavan Over a year ago

@MKD I agree with A.S. Simply copying code is not going to be helpful to you for the future should you face similar problems again. Instead, learn and revise the code; understand what each code block is doing so that you can learn and create custom code; and you will find that you can debug better since you will understand the code. Good luck
