homescreen

I am developing an iphone app where i have to change lockscreen image programmatically when app is running in background.I have got lots of stuff saying it is not possible but there is an app for this please let me know how to acheive this. Thanks. The only way you can change the lockscreen image is when you are playing audio. Police Scanner+ does play audio, and therefore can set an image. This only works with iOS 5+ and is done something like this. - (void)setupNowPlayingInfoCenter:(MPMediaItem *)currentSong { NSString *ver = [[UIDevice currentDevice] systemVersion]; CGFloat version = 4.0;

I have a web app and on the Android I would like to display an alert describing how to add my app to the home screen. (Add it to "Bookmarks" and then "Add it to home screen" or "Add to shortcut in Home"). Then a icon will be displayed on the screen that opens my app. But off course I only want this to show if the app is not added to the home screen. Does anybody know how to do this? Any input appreciated, thanks. Yes, you can. While technically a page open in Chrome browser tab can't directly check whether a home screen shortcut exists, the page's local data ( localStorage , IndexedDB) is

Okay, I asked another question here trying to make my activities look like dialogs. I'm thinking maybe instead of asking about a specific method, I should ask about what I'd like to do, and perhaps there is a different way to go about it... Here's what I have. My app allows shortcuts to be placed on the home screen. The code and logic for creating the shortcuts all works flawlessly, and the shortcuts then launch the proper activity which shows what it's supposed to... again, all works flawlessly. What I'm wondering though, is is there a way to have the home screen shortcut launch my activity

I'm making a Live wallpaper for Android, and I want it scroll as user scroll the home screen. I can do that, but on some phones, user can choose the number of home screen. Is there anyway to get the number of home screen? Thanks. There is actually a way to know the number of home screens. The 'onOffsetsChanged' call provides to arguments for that porpouse: float xOffset and float xOffsetStep. xOffset goes from 0 to 1 and xOffsetStep represents the step size for each home scree. So if you configure your home screen with 6 'desktops' xOffsetStep would be 0.2. So the final way to check the number

Can someone tell me how to check that my widget have been placed on the homescreen? I have some code in my app that should run only if the widget is placed on the homescreen. You need to store that information yourself. I usually use the application preferences, but you could use anything. Generally widgets use services to communicate, so your code that does stuff is likely in a service, but using the preference allows any portion of your app to access this. In your widget class that extends AppWidgetProvider the onEnabled is called when the widget is put on a homescreen and the onDeleted is
