I am facing issue in Last three parameters. Please Help me if you have done it.Thank You in Advance...

Answer 1

I successfully uploaded the images to Foursquare via the code below:

mBitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream);
byte[] bitmapdata = stream.toByteArray();

HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("https://api.foursquare.com/v2/photos/add");

try 
{
    MultipartEntity entity = new MultipartEntity();
    entity.addPart("v", new StringBody("20121210")); 
    entity.addPart("venueId", new StringBody(venue.getId()));
    entity.addPart("public", new StringBody("1"));
    entity.addPart("oauth_token", new     StringBody(mAccessToken));
    ByteArrayBody imgBody = new ByteArrayBody(bitmapdata, "image/jpeg",    "FS_image");

    entity.addPart("image",imgBody);
    httppost.setEntity(entity);
    HttpResponse response = httpclient.execute(httppost);
    Log.v("response","" +response);
    responseResult = inputStreamToString(response.getEntity().getContent()).toString();
} 
catch (ClientProtocolException e) 
{
    Log.d(TAG, "Opening URL " +e);
} 

Answer 2

The parameters postUrl, postContentId, and postText are optional, so you do not need to provide them. postUrl and postContentId are used to provide a link that your photo can link to for more information. postText is a short comment about the photo.

Answer 3

/* * put foursquare sdk file into projects libs folder and the later code into the Activity file */

todaydate = Latest Date;
venueId = The Venue Id is important.
URL = The image url from which the image will be downloaded to sd card;

foursquare = new Foursquare(
        "Your Client Id", //*client id
        "Your Client Secret", //*client secret
        "Callback Url");

foursquare.authorize(ActivityName.this, new FoursquareAuthenDialogListener());

// Creates Bitmap from InputStream and returns it   
private Bitmap downloadImage(String url) {
    Bitmap bitmap = null;
    InputStream stream = null;
    BitmapFactory.Options bmOptions = new BitmapFactory.Options();
    bmOptions.inSampleSize = 1;

    try {
        stream = getHttpConnection(url);
        bitmap = BitmapFactory.decodeStream(stream, null, bmOptions);
        stream.close();
    } catch (IOException e1) {
