    text
    copied!<p>I have encountered a problem in my Android application. The problem is that the I cannot parse some JSON code because it has no JsonObject. I'm pretty new to programming, and thus have no experience with JSON. Forgive me if this is a newb question. Here is my JSON code:</p> <pre><code>{ "item_id": "51c3d78797c3e6d8d3b546cf", "item_name": "Cola, Cherry", "brand_id": "51db3801176fe9790a89ae0b", "brand_name": "Coke", "item_description": "Cherry", "updated_at": "2013-07-09T00:00:46.000Z", "nf_ingredient_statement": "Carbonated Water, High Fructose Corn Syrup and/or Sucrose, Caramel Color, Phosphoric Acid, Natural Flavors, Caffeine.", "nf_calories": 100, "nf_calories_from_fat": 0, "nf_total_fat": 0, "nf_saturated_fat": null, "nf_cholesterol": null, "nf_sodium": 25, "nf_total_carbohydrate": 28, "nf_dietary_fiber": null, "nf_sugars": 28, "nf_protein": 0, "nf_vitamin_a_dv": 0, "nf_vitamin_c_dv": 0, "nf_calcium_dv": 0, "nf_iron_dv": 0, "nf_servings_per_container": 6, "nf_serving_size_qty": 8, "nf_serving_size_unit": "fl oz", } </code></pre> <p>Here's my code in my Android app.</p> <pre><code> public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build(); StrictMode.setThreadPolicy(policy); EditText one = (EditText) findViewById(R.id.editText1); setContentView(R.layout.dbfiller); Intent intent = getIntent(); final String message = intent.getStringExtra("bnum"); DefaultHttpClient httpclient = new DefaultHttpClient(new BasicHttpParams()); HttpPost httppost = new HttpPost("https://api.nutritionix.com/v1_1/item?upc="+message +"&amp;appId=926eed28&amp;appKey=d1366b0005a0d8f6898ff3df44b52867"); // Depends on your web service httppost.setHeader("Content-type", "application/json"); InputStream inputStream = null; String result = null; try { HttpResponse response = httpclient.execute(httppost); HttpEntity entity = response.getEntity(); inputStream = entity.getContent(); // json is UTF-8 by default BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream, "UTF-8"), 8); StringBuilder sb = new StringBuilder(); String line = null; while ((line = reader.readLine()) != null) { sb.append(line + "\n"); } result = sb.toString(); JSONObject json= (JSONObject) new JSONTokener(result).nextValue(); JSONObject json2 = json.getJSONObject(""); String test = (String) json2.get("nf_ingredient_statement"); one.setText(test); } catch (Exception e) { e.printStackTrace(); } finally { try{if(inputStream != null)inputStream.close();}catch(Exception squish){} } } </code></pre> <p>I think the problem is here:</p> <pre><code> JSONObject json= (JSONObject) new JSONTokener(result).nextValue(); JSONObject json2 = json.getJSONObject(""); String test = (String) json2.get("nf_ingredient_statement"); one.setText(test); </code></pre> <p>But I don't know what I did wrong. I've been banging my head on the wall for a while. Here's my Logcat:</p> <pre><code>11-29 12:36:13.636: W/System.err(25748): org.json.JSONException: No value for 11-29 12:36:13.636: W/System.err(25748): at org.json.JSONObject.get(JSONObject.java:355) 11-29 12:36:13.636: W/System.err(25748): at org.json.JSONObject.getJSONObject(JSONObject.java:574) 11-29 12:36:13.636: W/System.err(25748): at com.example.foodsaver2.DatabaseFiller.onCreate(DatabaseFiller.java:57) 11-29 12:36:13.636: W/System.err(25748): at android.app.Activity.performCreate(Activity.java:5243) 11-29 12:36:13.636: W/System.err(25748): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1087) 11-29 12:36:13.636: W/System.err(25748): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2140) 11-29 12:36:13.636: W/System.err(25748): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2226) 11-29 12:36:13.636: W/System.err(25748): at android.app.ActivityThread.access$700(ActivityThread.java:135) 11-29 12:36:13.636: W/System.err(25748): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1397) 11-29 12:36:13.636: W/System.err(25748): at android.os.Handler.dispatchMessage(Handler.java:102) 11-29 12:36:13.636: W/System.err(25748): at android.os.Looper.loop(Looper.java:137) 11-29 12:36:13.636: W/System.err(25748): at android.app.ActivityThread.main(ActivityThread.java:4998) 11-29 12:36:13.636: W/System.err(25748): at java.lang.reflect.Method.invokeNative(Native Method) 11-29 12:36:13.636: W/System.err(25748): at java.lang.reflect.Method.invoke(Method.java:515) 11-29 12:36:13.636: W/System.err(25748): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:777) 11-29 12:36:13.636: W/System.err(25748): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:593) 11-29 12:36:13.636: W/System.err(25748): at dalvik.system.NativeStart.main(Native Method) </code></pre> <p>The app doesn't crash because the json parser is located inside a try-catch method. What's wrong here? I've checked Google and SO, but I can't seem to find the solution. Any help regarding this problem is greatly appreciated.</p>
