Android Send photo to server using retrofit post method

Question

Hi guys first of all i am new to android and stack overflow.what i need is capture an image from camera and send to php server.

for capturing image i use

    Intent photo= new Intent("android.media.action.IMAGE_CAPTURE");
            startActivityForResult(photo, 0);

    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == 0 && resultCode == RESULT_OK) {
        Bundle extras = data.getExtras();
         imageBitmap = (Bitmap) extras.get("data");
        mImageView.setImageBitmap(imageBitmap);
        delete.setVisibility(View.VISIBLE);
        button.setVisibility(View.INVISIBLE);
        image = ConvertBitmapToString(imageBitmap);

    }
}

//method to convert the selected image to base64 encoded string//////////////
public String ConvertBitmapToString(Bitmap bitmap){

    ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
    bitmap.compress(Bitmap.CompressFormat.JPEG, 25, byteArrayOutputStream);

    String encodedImage= null;
    try {
        encodedImage = URLEncoder.encode(Base64.encodeToString(byteArrayOutputStream.toByteArray(), Base64.DEFAULT), "UTF-8");
    } catch (UnsupportedEncodingException e) {
        e.printStackTrace();
    }

    return encodedImage;
}

my problem is the image is not visible in server.

server connection

      public interface SaveAPI {
     @FormUrlEncoded
    @POST("/example.php")
public void insertUser(
        @Field("username") String name,
        @Field("coname") String cname,
        @Field("location") String location,
        @Field("ddate") String date,
        @Field("dracc") String daccnt,
        @Field("cracc") String cccnt,
        @Field("amount") String samt,
        @Field("narr") String snarration,
        @Field("bill") String image,
        Callback<Response> callback);

     }
   private void insertUser() {
    //Here we will handle the http request to insert user to mysql db
    //Creating a RestAdapter
        RestAdapter adapter = new RestAdapter.Builder()
            .setEndpoint(SAVE_URL) //Setting the Root URL
            .build();
       SaveAPI api = adapter.create(SaveAPI.class);
       api.insertUse r(
            name,
            sCname.getSelectedItem().toString(),
            loc,
            tdate,
            sdamount.getSelectedItem().toString(),
            scamount.getSelectedItem().toString(),
            amt.getText().toString(),
            narration.getText().toString(),
            image,
            new Callback<Response>() {
                @Override
                public void success(Response result, Response response) {
                    //On success we will read the server's output using 
            bufferedreader
                    //Creating a bufferedreader object
                    BufferedReader reader = null;

                    //An string to store output from the server
                    String output = "";

                    try {
                        //Initializing buffered reader
                        reader = new BufferedReader(new 
                    InputStreamReader(result.getBody().in()));

                        //Reading the output in the string
                        output = reader.readLine();
                    } catch (IOException e) {
                        e.printStackTrace();
                    }

                    //Displaying the output as a toast
                    Toast.makeText(ExpenseActivity.this, output, 
              Toast.LENGTH_LONG).show();
                }

                @Override
                public void failure(RetrofitError error) {
                    Toast.makeText(ExpenseActivity.this, error.toString(), 
               Toast.LENGTH_LONG).show();

                }

        }

Actually i am sending 9 data to the server,except image all are displayed in server anyone give solution to the problem.thanks in advance

Answer 1

Now my image conversation works perfectly........

    public String ConvertBitmapToString(Bitmap bitmap)throws 
    FileNotFoundException {
    BitmapFactory.Options options = null;
    options = new BitmapFactory.Options();
    options.inSampleSize = 3;
    ByteArrayOutputStream byteArrayOutputStream = new 
    ByteArrayOutputStream();
    bitmap.compress(Bitmap.CompressFormat.JPEG,40, byteArrayOutputStream);
    byte[] byteArrayImage = byteArrayOutputStream.toByteArray();
    String encodedImage = 
    Base64.encodeToString(byteArrayImage,Base64.DEFAULT);
    return encodedImage;
   }

Answer 2

first check whether that converted image as string is returning data and that response is a valid response u intented to get by again converting it into image.

Answer 3

first of all, debug the app, and check if the image converts into base64. If it is converting correctly and you send it to your server, the problem is in your server server. Debug please your project and tell what is happening. Pot please the part of the server code where you bind the data
