POAndroid: IllegalStateException in HttpGet
text
Body
copied!<p>I'm trying to send a <code>GET</code> request using <code>HttpClient</code>, but I keep getting an <code>IllegalStateException</code>. Any idea what's causing this? I've been looking around for a solution, but I don't get what it means by <code>"host=null"</code> in the log. How do I set the host, and how is it different from the path? Here's my logcat out:</p> <pre><code>07-17 11:54:18.002: W/System.err(15422): java.lang.IllegalStateException: Target host must not be null, or set in parameters. scheme=null, host=null, path=google.com 07-17 11:54:18.002: W/System.err(15422): at org.apache.http.impl.client.DefaultRequestDirector.determineRoute(DefaultRequestDirector.java:591) 07-17 11:54:18.002: W/System.err(15422): at org.apache.http.impl.client.DefaultRequestDirector.execute(DefaultRequestDirector.java:293) 07-17 11:54:18.002: W/System.err(15422): at org.apache.http.impl.client.AbstractHttpClient$1.executeRequestSending(AbstractHttpClient.java:609) 07-17 11:54:18.002: W/System.err(15422): at org.apache.http.impl.client.naf.redirect.NafRequestExecutorWrapperRedirectionHandler.executeRequestSendingUsual(NafRequestExecutorWrapperRedirectionHandler.java:96) 07-17 11:54:18.002: W/System.err(15422): at org.apache.http.impl.client.naf.redirect.NafRequestExecutorWrapperRedirectionHandler.executeRequestSending(NafRequestExecutorWrapperRedirectionHandler.java:73) 07-17 11:54:18.002: W/System.err(15422): at org.apache.http.impl.client.naf.auth.NafHttpAuthStrategyDefault.sendFirstRequest(NafHttpAuthStrategyDefault.java:487) 07-17 11:54:18.002: W/System.err(15422): at org.apache.http.impl.client.naf.auth.NafHttpAuthStrategyDefault.performAuthExecutionUnsafe(NafHttpAuthStrategyDefault.java:388) 07-17 11:54:18.002: W/System.err(15422): at org.apache.http.impl.client.naf.auth.NafHttpAuthStrategyDefault.performAuthExecution(NafHttpAuthStrategyDefault.java:200) 07-17 11:54:18.002: W/System.err(15422): at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:558) 07-17 11:54:18.002: W/System.err(15422): at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:508) 07-17 11:54:18.002: W/System.err(15422): at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:486) 07-17 11:54:18.002: W/System.err(15422): at myapp.httprequest.free.GETActivity$1sendRequestTask.doInBackground(GETActivity.java:102) 07-17 11:54:18.002: W/System.err(15422): at myapp.httprequest.free.GETActivity$1sendRequestTask.doInBackground(GETActivity.java:1) 07-17 11:54:18.002: W/System.err(15422): at android.os.AsyncTask$2.call(AsyncTask.java:264) 07-17 11:54:18.002: W/System.err(15422): at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:305) 07-17 11:54:18.002: W/System.err(15422): at java.util.concurrent.FutureTask.run(FutureTask.java:137) 07-17 11:54:18.002: W/System.err(15422): at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1076) 07-17 11:54:18.002: W/System.err(15422): at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:569) 07-17 11:54:18.002: W/System.err(15422): at java.lang.Thread.run(Thread.java:856) </code></pre> <p>and the source:</p> <pre><code>HttpClient getClient = new DefaultHttpClient(); HttpGet getData = new HttpGet(this.address); try { HttpResponse gameResponse = getClient.execute(getData); return EntityUtils.toString(gameResponse.getEntity()); } catch (ClientProtocolException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } catch (IllegalStateException e) { e.printStackTrace(); } </code></pre>
