    copied!<p>I've created a class <code>UploadToImgurTask</code> as an AsyncTask that takes a single file path parameter, creates and sets an MultiPartEntity, and then uses Apache HttpClient to upload the image with said entity. The JSON response from Imgur is saved in a JSONObject, the contents of which I display in LogCat for my own understanding.</p> <p>Here's a screenshot of the JSON I receive from Imgur:</p> <p><img src="https://i.stack.imgur.com/738jW.png" alt="Imgur Screenshot"> </p> <p>I looked up error Status 401 on api.imgur.com and it says that I need to authenticate using OAuth <strong>despite</strong> the fact that Imgur has stated very clearly that apps do not need to use OAuth if images are being uploaded anonymously (which is what I am doing right now).</p> <pre><code>class UploadToImgurTask extends AsyncTask&lt;String, Void, Boolean&gt; { String upload_to; @Override protected Boolean doInBackground(String... params) { final String upload_to = "https://api.imgur.com/3/upload.json"; final String API_key = "API_KEY"; final String TAG = "Awais"; HttpClient httpClient = new DefaultHttpClient(); HttpContext localContext = new BasicHttpContext(); HttpPost httpPost = new HttpPost(upload_to); try { final MultipartEntity entity = new MultipartEntity( HttpMultipartMode.BROWSER_COMPATIBLE); entity.addPart("image", new FileBody(new File(params[0]))); entity.addPart("key", new StringBody(API_key)); httpPost.setEntity(entity); final HttpResponse response = httpClient.execute(httpPost, localContext); final String response_string = EntityUtils.toString(response .getEntity()); final JSONObject json = new JSONObject(response_string); Log.d("JSON", json.toString()); //for my own understanding return true; } catch (Exception e) { e.printStackTrace(); } return false; } } </code></pre> <hr> <p>After doInBackground returns the link to the uploaded image to onPostExecute, I want to copy it to the system clipboard, but Eclipse keeps saying getSystemService(String) isn't defined within my ASyncTask class. </p> <p>There is no legit way to return link (a String) back to the main thread, so I have to do whatever I have to do within onPostExecute within UploadToImgurTask (which extends ASyncTask)</p> <pre><code> @Override protected void onPostExecute(String result) { super.onPostExecute(result); ClipboardManager clipboard = (ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE); ClipData clip = ClipData.newPlainText("label", "Text to copy"); clipboard.setPrimaryClip(clip); } </code></pre> <p>What's causing the problem? </p>
