UnknownHostException error

[SpaceCow]

Hi,

I was working on my app all day and suddenly I get this message in the logs:

Error. Url=http://android.xxxxx.com/rss.xml?UUID=321455557777 Message=java.net.UnknownHostException: android.xxxxx.com

My app won't connect to any host at the moment. I changed to another server, checked the feed, opened an backup that used to work but still that message!

Can someone please tell me what to do? I get no errors when I debug the code and I get the same error when I install the APK on my phone.

Thank!

This error means that the device cannot resolve the host to an IP address.
Make sure that the device is connected to the internet. If you are working with the emulator then try to restart it.

What i said, i changed to another server (different IP, other location) and installed the app on my phone (wich uses another connection). On the emulator and on my phone i was getting the same error.

I closed b4a en re-opened all the files and the error is gone. It was very strange... i tried everything. It seems solved!

I still have another problem though. I have a tabhost with 3 pages attached. From one of the pages i want to go to another page so i use Panel.LoadLayout("page3"). Now the page is showed and it looks great... the only problem is that i can't fill the listview on that page!

When i use Panel4.AddView(ListView1, 0, 0, 100%x, 100%y) and put some data in it, the listview doesn't show. When i change the panel name to Panel1 it works perfectly but not on a page that is not shown.

I checked all names, checked for double panels/listviews and nothing...

Do you have some advise?

It is better to start a new thread for a new question.
Calling Panel.LoadLayout will load the layout file to the current panel. Is this what you really want? Don't you want to switch the current tab instead?

I don't want another tab for this page. It is just a subpage from a tab.

Like this structure:

Tab1 -> Page1
Tab2 -> Page2 -> Subpage2
Tab3 -> Page3

I thought a new page in the designer with an panel in it does the job... But it seems not to

(for other questions i will open a net thread next time )

See this thread for a number of examples of working with multiple layouts: http://www.b4x.com/forum/basic4andr...6-different-examples-2-layouts.html#post47102

It is not possible to say what is the problem without seeing the code.
Is Panel4 visible? Are you sure that there are no views with the same name in other layouts?
Please upload your project if you do not find the problem (File - Export as zip).
