    <p>I'm relatively new to Android development and am writing my first REST-based app. I've opted to use the <a href="http://loopj.com/android-async-http/" rel="nofollow">Android Asynchronous HTTP Client</a> to make things a bit easier. I'm currently just running through the main "Recommended Usage" section on that link, essentially just creating a basic static HTTP client. I'm following the code given, but changing it around to refer to a different API. Here's the code in question:</p> <pre><code> public void getFactualResults() throws JSONException { FactualRestClient.get("q=Coffee,Los Angeles", null, new JsonHttpResponseHandler() { @Override public void onSuccess(JSONArray venues) { // Pull out the first restaurant from the returned search results JSONObject firstVenue = venues.get(0); String venueName = firstVenue.getString("name"); // Do something with the response System.out.println(venueName); } }); } </code></pre> <p>The <code>String venueName = firstVenue.getString("name");</code> line is currently throwing an error in Eclipse: "Type mismatch: cannot convert from Object to JSONObject". Why is this error occurring? I searched other threads which led me to try using <code>getJSONObject(0)</code> instead of <code>get(0)</code> but that led to further errors and Eclipse suggesting using try/catch. I haven't changed any of the code on the tutorial, save for the variable names and URL. Any thoughts/tips/advice?</p> <p>Thanks so much.</p> <p>EDIT:</p> <p>Here is the onSuccess method, modified to include the try/catch blocks suggested. Eclipse now shows the "local variable may not have been initialized" for firstVenue here: <code>venueName = firstVenue.getString("name");</code> and for venueName here: <code>System.out.println(venueName);</code> Even if I initialize <code>String venueName;</code> directly after <code>JSONObject firstVenue;</code> I still get the same error. Any help in resolving these would be greatly appreciated!</p> <pre><code>public void onSuccess(JSONArray venues) { // Pull out the first restaurant from the returned search results JSONObject firstVenue; try { firstVenue = venues.getJSONObject(0); } catch (JSONException e) { // TODO Auto-generated catch block e.printStackTrace(); } String venueName; try { venueName = firstVenue.getString("name"); } catch (JSONException e) { // TODO Auto-generated catch block e.printStackTrace(); } // Do something with the response System.out.println(venueName); } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
