Here I want to display the JSON content using API key. But I am unable to get the authentication.
I am getting the error in JsonObject:
org.json.JSONException: Value Authorization of type java.lang.String cannot be converted to JSONObject In my android application, I just pass the API key and URL id to get the JSON response in the following URL. I display the JSON content using JSON array.
But if I:
public class AndroidAPiActivity extends Activity { /* * FlickrQuery = FlickrQuery_url * + FlickrQuery_per_page * + FlickrQuery_nojsoncallback * + FlickrQuery_format * + FlickrQuery_tag + q * + FlickrQuery_key + FlickrApiKey */ String FlickrQuery_url = ""; String FlickrQuery_per_page = "&per_page=1"; String FlickrQuery_nojsoncallback = "&nojsoncallback=1"; String FlickrQuery_format = "&format=json"; String FlickrQuery_tag = "&tags="; String FlickrQuery_key = "&api_key="; // Apply your Flickr API: // String FlickrApiKey = "f65215602df8f8af"; EditText searchText; Button searchButton; TextView textQueryResult, textJsonResult; ImageView imageFlickrPhoto; Bitmap bmFlickr; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); searchText = (EditText)findViewById(R.id.searchtext); searchButton = (Button)findViewById(R.id.searchbutton); textQueryResult = (TextView)findViewById(R.id.queryresult); textJsonResult = (TextView)findViewById(R.id.jsonresult); imageFlickrPhoto = (ImageView)findViewById(R.id.flickrPhoto); searchButton.setOnClickListener(searchButtonOnClickListener); } private Button.OnClickListener searchButtonOnClickListener = new Button.OnClickListener(){ public void onClick(View arg0) { // TODO Auto-generated method stub String searchQ = searchText.getText().toString(); String searchResult = QueryFlickr(searchQ); textQueryResult.setText(searchResult); String jsonResult = ParseJSON(searchResult); textJsonResult.setText(jsonResult); if (bmFlickr != null){ imageFlickrPhoto.setImageBitmap(bmFlickr); } }}; private String QueryFlickr(String q){ String qResult = null; String qString = FlickrQuery_url + FlickrQuery_per_page + FlickrQuery_nojsoncallback + FlickrQuery_format + FlickrQuery_tag + q + FlickrQuery_key + FlickrApiKey; HttpClient httpClient = new DefaultHttpClient(); HttpGet httpGet = new HttpGet(qString); try { HttpEntity httpEntity = httpClient.execute(httpGet).getEntity(); if (httpEntity != null){ InputStream inputStream = httpEntity.getContent(); Reader in = new InputStreamReader(inputStream); BufferedReader bufferedreader = new BufferedReader(in); StringBuilder stringBuilder = new StringBuilder(); String stringReadLine = null; while ((stringReadLine = bufferedreader.readLine()) != null) { stringBuilder.append(stringReadLine + "\n"); } qResult = stringBuilder.toString(); } } catch (ClientProtocolException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } return qResult; } private String ParseJSON(String json){ String jResult = null; bmFlickr = null; String key_id; String category; String subcategory; String title; String icon_image; try { JSONObject JsonObject = new JSONObject(json); JSONObject Json_photos = JsonObject.getJSONObject("interests"); JSONArray JsonArray_photo = Json_photos.getJSONArray("interest"); //We have only one photo in this exercise JSONObject FlickrPhoto = JsonArray_photo.getJSONObject(0); key_id = FlickrPhoto.getString("row_key"); category = FlickrPhoto.getString("category"); subcategory = FlickrPhoto.getString("subcategory"); title = FlickrPhoto.getString("title"); jResult = "\n key_id: " + key_id + "\n" + "category: " + category + "\n" + "subcategory: " + subcategory + "\n" + "title: " + title + "\n"; bmFlickr = LoadPhotoFromFlickr(key_id, category, subcategory,title); } catch (JSONException e) { // TODO Auto-generated catch block e.printStackTrace(); } return jResult; } private Bitmap LoadPhotoFromFlickr( String key_id, String category, String subcategory, String title){ Bitmap bm= null; String icon_image = null; // String FlickrPhotoPath =""; String FlickrPhotoPath =""+icon_image+".jpg"; URL FlickrPhotoUrl = null; try { FlickrPhotoUrl = new URL(FlickrPhotoPath); HttpURLConnection httpConnection = (HttpURLConnection) FlickrPhotoUrl.openConnection(); httpConnection.setDoInput(true); httpConnection.connect(); InputStream inputStream = httpConnection.getInputStream(); bm = BitmapFactory.decodeStream(inputStream); } catch (MalformedURLException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } return bm; } } 6 Answers
Update:
Based on the HTML response, I can tell you that this is not JSON. The response tells me that you have the incorrect URL for your web service.
You need to check your URL.
Extra Info / Previous Answer:
It looks like the simple answer is the right one - your result is not a valid JSON string. See JSON.org website for details on what JSON should look like.
Check out JSON Parser Online - I find its very useful when working with JSON.
It is strange that you are requesting JSON, and it is not returning it properly - perhaps I have missed something.
6Yes, we get such kind of warning when the given URL is not valid.
Just check the URL once.
Remove docType from API. and set content Type Application/json . (as text/html will not read as json . thus you were seeing the error.)

Solved.
It turns out the runtime error stretched back to the previous video.
I was doing
JSONObject currently = new JSONObject("currently"); instead of
JSONObject currently = forecast.getJSONObject("currently"); So my guess is Android thought I was trying to setup an entirely new JSON object instead of trying to retrieve information from an existing one! :) Now the console displays the time perfectly!
I've faced this issue too, I changed my Internet connection to another network and it works.
The problem was that ISP doesn't accept http access.
Another solution you can open VPN and try again, and maybe it works...
I received the same "<!Doctype..." error when working with Google Translate's json URLs. Then, I found this code somewhere and it worked :
BasicHttpParams basicHttpParams = new BasicHttpParams(); HttpConnectionParams.setConnectionTimeout((HttpParams)basicHttpParams, (int)10000); HttpConnectionParams.setSoTimeout((HttpParams)basicHttpParams, (int)10000); HttpConnectionParams.setTcpNoDelay((HttpParams)basicHttpParams, (boolean)true); DefaultHttpClient defaultHttpClient = new DefaultHttpClient((HttpParams)basicHttpParams); HttpGet httpGet = new HttpGet(url); BasicResponseHandler basicResponseHandler = new BasicResponseHandler(); JSONObject json=null; try { json = new JSONObject((String)defaultHttpClient.execute((HttpUriRequest)httpGet, (ResponseHandler)basicResponseHandler)); } catch (ClientProtocolException e) { e.printStackTrace(); } catch (JSONException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); }
