Ive got two activities in the same application.
the first one is with gui(main activity)
the second one is a listener which works infinite without gui.

Wierd problem occurs:

i am running the second activity with a diffrent thread so i could keep on
manipulate the gui..

but for some reason, the gui losing it’s focus for some reason, only when i press ‘home’ and come back to it, then i can continune maniuplate the gui.

it feels like after i launch the second activity, the gui activity(the main) is losing the focus.
how come?

in my mainactivity i have:

setContentView(R.layout.main);

and its setted as the launcher in the manifest.

thanks,

ray.

    I don’t think trying to have more then one Activity open at a time is right according to the “Android Model”.

    According to the guide:

    “An activity presents a visual user
    interface for one focused endeavor the
    user can undertake”

    If it had any GUI elements associated with it you might want to create a dialog. But if it is truly a background operation do what the guy before me said.
