Widget Update when user switches homescreen

Is there an Event that is fired when an widget becomes visible on to the homescreen. I didn't mean at install time, I mean if the user changes his homescreen by wiping the surface of the phone. The background of this question is that I setup a timer in a service inside the widget that gets updates from a url but that should stop if the widget is not on the current homescreen.

No, sorry. There are dozens of home screen applications, some of whom may not even have the concept of "wiping the surface of the phone". A home screen is merely an activity with a particular <intent-filter>.

This is strange. I put the Yahoo-Currency Widget on an different homescreen. If I wipe from my default homescreen to that screen this widget starts to update its curreny data. So somehow it knows that it is visible now.

How do you you know it is only on the swipe that it "starts to update its currency data"?

I didn't know it. I just see it. What's your guess?

Do you think that it is updating all the time and I just think that it is done when I activate it? BTW. I have a Desire with HTC Sense but I can see the same effect on my Android 2.1 Emulator. I will try to check out if the yahoo-widget keeps updating when it is on an invisible screen.

I believe the app widget is updating all of the time. If you have solid evidence to the contrary, let me know!

I will try to find it out in my development machine. The expierence are from my real mobile. In my developing machine I have a lot more informations whats going on.

There is a way to do that, you can listen to Intent.ACTION_USER_PRESENT broadcast and update your widget on receiving the intent.

It will be fired when the user unlocks the home screen.

I am using it in my app and works great to update your widgets upon unlock.

Not sure if this helps, but I stumbled across this..

WallpaperManager.setWallpaperOffsets() and WallpaperService.onOffsetChanged()

Perhaps you could use this? Set wallpaper offsets and use onOffsetChanged() to get current offsets?
