How to upload an image from Android using foursqua

Question

I know how to deal with foursquare API https://developer.foursquare.com/docs/photos/add

I tried this: Sending images using Http Post

Here's my code:

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == CAMERA_PIC_REQUEST) {
        if (resultCode == RESULT_OK) {
            Uri imageUri = data.getData();
            List<NameValuePair> params = new ArrayList<NameValuePair>(4);
            Intent intent = getIntent();
            String message = intent.getStringExtra(SignIn.EXTRA_MESSAGE);
            params.add(new BasicNameValuePair("venueId", message));
            params.add(new BasicNameValuePair("image", imageUri.getPath()));
            Log.d("myresponse", imageUri.getPath());
            params.add(new BasicNameValuePair("oauth_token",
                    [myoauthtoken]));
            params.add(new BasicNameValuePair("v", "20121210"));
            post("https://api.foursquare.com/v2/photos/add", params);
        } 
    }
}

But I get an exception with this stack trace:

Answer 1

You're attempting to make a HTTP request on your UI thread. The exception is NetworkOnMainThreadException, which means you should be doing your work in a background thread.

For doing your upload, I suggest using something like an IntentService to do your HTTP post. In addition to the documentation, you can also check out an example app of mine that highlights different methods for getting work done outside the UI thread.
