POhttpClient.execute(httpPost) causing crash (Android 4.1)
text
Body
copied!<p>maybe you can help me out. I'm working on an Android app project that calls on the Rotten Tomatoes API, which returns JSON data. But whenever I run my code the application crashes. The specific bit of code that's giving me problems is httpClient.execute(httpPost);</p> <p>The url string that's being passed to the method is fine and returns the correct data when I type it in my browser, so I know that isn't the problem. I'm kinda at a loss. I've never had an issue with an HttpClient, though in the past I've only worked with XML, never JSON.</p> <p>I've been struggling with this for a while now. If anyone has any insight, it would be greatly appreciated.</p> <pre><code> public JSONObject getJSON(String url) { //Make HTTP Request try { //defaultHttpClient DefaultHttpClient httpClient = new DefaultHttpClient(); HttpPost httpPost = new HttpPost(url); //Log.d("RunTest", url); HttpResponse httpResponse = httpClient.execute(httpPost); // THIS LINE CAUSES APPLICATION TO CRASH HttpEntity httpEntity = httpResponse.getEntity(); is = httpEntity.getContent(); } catch (UnsupportedEncodingException uee) { Log.d("Exceptions", "UnsupportedEncodingException"); uee.printStackTrace(); } catch (ClientProtocolException cpe) { Log.d("Exceptions", "ClientProtocolException"); cpe.printStackTrace(); } catch (IOException ioe) { Log.d("Exceptions", "IOException"); ioe.printStackTrace(); } 10-27 02:52:44.484: I/Choreographer(627): Skipped 147 frames!
