Question

 I am new to android. So, not able to trace out the error message while uploading image to the server. 

I got some code from the internet for uploading image to the server and the link is and changed my program accordingly . When am trying to run the program it is giving error message in the emulator as following screen shot.

And even checked all the things in the local host and it is running fine. And here is my code for upload image.Please check this and give me some suggestions.

public class uploadimage extends Activity {

    InputStream inputStream;

        @Override

    public void onCreate(Bundle icicle) {

            super.onCreate(icicle);

            setContentView(R.layout.main);



            Bitmap bitmap = BitmapFactory.decodeResource(getResources(),R.drawable.icon);           ByteArrayOutputStream stream = new ByteArrayOutputStream();

            bitmap.compress(Bitmap.CompressFormat.PNG, 90, stream); //compress to which format you want.

            byte [] byte_arr = stream.toByteArray();

            String image_str = Base64.encodeBytes(byte_arr);

            ArrayList<NameValuePair> nameValuePairs = new  ArrayList<NameValuePair>();



            nameValuePairs.add(new BasicNameValuePair("image",image_str));



            try{

                HttpClient httpclient = new DefaultHttpClient();

                HttpPost httppost = new HttpPost("http://localhost/Upload_image_ANDROID/upload_image.php");

                httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

                HttpResponse response = httpclient.execute(httppost);

                String the_string_response = convertResponseToString(response);

                Toast.makeText(uploadimage.this, "Response " + the_string_response, Toast.LENGTH_LONG).show();

            }catch(Exception e){

                  Toast.makeText(uploadimage.this, "ERROR " + e.getMessage(), Toast.LENGTH_LONG).show();

                  System.out.println("Error in http connection "+e.toString());

            }

        }


        public String convertResponseToString(HttpResponse response) throws IllegalStateException, IOException{



             String res = "";

             StringBuffer buffer = new StringBuffer();

             inputStream = response.getEntity().getContent();

             int contentLength = (int) response.getEntity().getContentLength(); //getting content length…..

             Toast.makeText(uploadimage.this, "contentLength : " + contentLength, Toast.LENGTH_LONG).show();

             if (contentLength < 0){

             }

             else{

                    byte[] data = new byte[512];

                    int len = 0;

                    try
                    {

                        while (-1 != (len = inputStream.read(data)) )

                        {

                            buffer.append(new String(data, 0, len)); //converting to string and appending  to stringbuffer…..

                        }

                    }

                    catch (IOException e)

                    {

                        e.printStackTrace();

                    }

                    try

                    {

                        inputStream.close(); // closing the stream…..

                    }

                    catch (IOException e)

                    {

                        e.printStackTrace();

                    }

                    res = buffer.toString();     // converting stringbuffer to string…..



                    Toast.makeText(uploadimage.this, "Result : " + res, Toast.LENGTH_LONG).show();

                    //System.out.println("Response => " +  EntityUtils.toString(response.getEntity()));

             }

             return res;

        }

}

Thanks in advance.

Answer 1

Instead of

"http://localhost"

use

http://10.0.2.2

its for emulator. And if you want to test for device then use specific IP of System given by router or network.

Thankx.
