PhoneGap App connect error

I hope this solves some of your problem too. If your PhoneGap app says that "Server is running" with given IP Address and port, chances are that the app is serving the files through it server well.

 I didn't need internet in my mobile device so I was working offline. However, my device when I try to connect through Phonegap Developer app in mobile device gives: "Error" .... "Time Out" message. Obviously some problem with connection? 

I connect back to mobile internet in device, but no, the problem still persists. Then I connect to my wifi network, and Problem Solved! Yes, I realised that the way it works is like a intranet. The reasons this happened was my computer and device were not in the same network, this does not have to be related to internet but just same network so that the IP address that Developer app is serving the files can be reached by device. Like simple server/client system, thats is only possible if they are in same network. Hopefully this solves few minutes of your wondering and pondering

!MESSAGE The workspace exited with unsaved changes in the previous session; refreshing workspace to recover changes.

This might happen when:

• sometimes the computer is put for hibernate many times when the eclipse is still working or
• resources gets called too early before the instance of workspace can be created, or
• Eclipse did not shutdown correctly.

And eclipse might crash (freeze on splash) with messages like (check workspace\.metadata\.log)

!ENTRY org.eclipse.core.resources 2 10035 2011-07-12 00:32:14.925
!MESSAGE The workspace exited with unsaved changes in the previous session; refreshing workspace to recover changes.

It might need to starting everything with a new workspace and then set up all the projects again properly (takes hours to do). Some solutions that can be worth trying :

1.  remove folder workspace\.metadata\.plugins\org.eclipse.core.resources\.root\.indexes
   and restart Eclipse (Referenced here) . Good to rename rather than delete because some also metioned that there was some other problem after that.
2.  Go to:
   \.metadata\.plugins\org.eclipse.core.resources and remove the file .snap
   
   Or remove file : .metadata\.plugins\org.eclipse.core.resources\.projects\<project>\.markers.snap . This is a large snapshot file which Eclipse constantly polls for some projects. (Referenced from here )
3. The third solution (which worked for me) is  when workbench is restarted/quit, then its need to save the workspace, before existing the workbench then the above message comes.
   

   Overload the preWindowShellClose() method in your of WorkbenchWindowAdvisor. You can save the workspace by using ResourcesPlugin.getWorkspace().save(...) method. (Sited here)

   import org.eclipse.core.resources.ResourcesPlugin;
   import org.eclipse.core.runtime.CoreException;
   import org.eclipse.ui.application.WorkbenchWindowAdvisor;
   
   public class ApplicationWorkbenchWindowAdvisor extends WorkbenchWindowAdvisor {
   
      // other methods...
   
      @Override
      public boolean preWindowShellClose() {
         try {
            // save the full workspace before quit
            ResourcesPlugin.getWorkspace().save(true, null);
         } catch (final CoreException e) {
            // log exception, if required
         }
   
         return true;
      }
   
   }

   
   

Another day of "sigh"

This error/exception belongs to wrong Run Configurations in the project.:

My setting was set with an product mode (Program to run:) , and it thus could not start. Changing the Program to run as Run as application and setting the "plugin" tabs to the default mode solved and saved the rest of day. I thought this was worth mentioning, as it was taking almost 3-4 hours of my time and googling the problems, even though there was no problem - just a mis configurations, sighhhh indeed.
