    copied!<p>I have a service that I'm using to send SOAP Webservice calls. Everything is working perfectly and it never crashes, but I kinda think it should.</p> <p>My problem is that when I have long running queries (10-50 sec.) onDestroy() is called before my workerthread is done (and I call stopSelfResult). Could it be that System.out.println isn't executed right away/out of sync (cached) in the LogCat window?</p> <p>The is how a start the service through QueryBase class:</p> <pre><code>QueryBase someService = new QueryBase(myActivity); someService.execute(...); </code></pre> <p>My QueryBase Class</p> <pre><code>public class QueryBase { private WeakReference&lt;Activity&gt; currentActivity = null; private static class ResponseHandler extends Handler { private QueryBase mQueryBase; public ResponseHandler(QueryBase vQueryBase) { mQueryBase = vQueryBase; }; public void handleMessage(Message message) { Bundle extras = message.getData(); mQueryBase.handleResult(message.arg1,message.arg2,extras.getInt("FRAMEID"),extras.getString("RESPONSE")); mQueryBase=null; }; }; public QueryBase(Activity vActivity) { currentActivity = new WeakReference&lt;Activity&gt;(vActivity); } /*************************************************************************** * Start the service **************************************************************************/ public boolean execute(Activity vActivity, int cmdID, int frameID, String serverAddress, int requestType, String request) { // Valid activity if (vActivity==null) return false; // Test to see if network is connected if (!isOnline(vActivity)) return false; Intent webService = new Intent(vActivity, WebService.class); final ResponseHandler responseHD = new ResponseHandler(this); Messenger messenger = new Messenger(responseHD); webService.putExtra("QUERYRESULT_MESSENGER",messenger); webService.putExtra("CMDID", cmdID); webService.putExtra("FRAMEID",frameID); webService.putExtra("SERVER_ADDRESS",serverAddress); webService.putExtra("REQUEST_TYPE",requestType); webService.putExtra("REQUEST",request); vActivity.startService(webService); return true; } /*************************************************************************** * Is my Android connected?
