What is an alternate entry point in a BlackBerry application?
When should we use this?
Is it for doing background processing?
If the alternate entry point has an icon, then which icon is shown in the BlackBerry app folders -- the main application icon or the alternate app icon?
It is indeed for launching apps that run in the background. See Running in the Background and Creating an Always-On Experience for more details.

I need to create sticky button which is on screen like hike button in ios
If i detect that application(WhatsApp) state event so i solve this problem. Thats why i need to create another application launched event.
Thank you in advance.
Apps on iOS are sandboxed and can not directly communicate with other apps directly. There are some API's in the iOS SDK which allows some interaction, mostly audio, share of items.
Apple does not expose to you app if an other app is launched, so checking that an other is launched is not possible.
The second issue is that you can draw on de screen outside of you own apps windows. So you will not be able to draw a button on top of some other app.
Is there a way to display progress on Ios App icon on the launcher/ main screen like they have default when installing or downloading an app from App store?
I have content that is being downloaded/uploaded in the background. I want to display continuous progress on app icon.
A circular progress bar is not important. I am just looking if there is any provision for such situations.
This is not possible.
Apple does expose any API methods for adding a layer to the app icon on the springboard.
Also changing your apps icon to include the progress will not work, since the app icon is in your apps main bundle which is readonly.
i don't know if it is still possible to use these red numbers like for whatsapp when you receive a message.
Maybe that would be an idea. You could Show the "%" of the upload/download that way.
I am new to IOS, I have a question which is
I have few separate apps. After installation of these apps. It show as different apps icon in the home screen and I have to manually move these apps together to form a folder with apps contains. Do we have any ways to make these apps install and form a folder automatically by programmatically ways?
If yes, can show me how it can be done?
Sorry for my lousy English.
Thanks.
Unfortunately, you cannot do this on a non jailbroken iOS device. Each app is only responsible for what's going on inside the app. There are some exceptions to this (you can run certain logics in the background, subscribe to be woken up as a result of a certain notification, or provide an extension for the user to add to their Today screen or use via other apps), but you have no control over the user's home screen. Positioning the icons there is in the sole responsibility of your user.
I have an application which needs to connect to server whenever the iPhone is active (i.e when the display screen is on). For this to work I need below 2 things.
In android we have combination of
BroadcastReceiver to get notified when the screen is active
Services to run the app process in the back ground to accomplish this task.
But in iOS I couldn't find any such service. Is there any way I can accomplish this task in iOS 8 ? Are there any equivalents for the above 2 in iOS ?
Check out this part of the documentation on downloading data in the background. You'll want to implement application:performFetchWithCompletionHandler: in your AppDelegate, turn on "Background Modes" in the Capabilities (find by clicking top item in Project navigator, the one with the blue icon next to it), and checkmark "Background fetch".
Note that the system decides when to call application:performFetchWithCompletionHandler:-- it is entirely opaque to us. It is only called when your app is not the app running in the foreground.
I don't know of any way to get a notification every time the device is unlocked.
I am trying to deploy a monitoring app and was wondering if one could prevent it from showing up in the most used list.
If you extend your app from Application instead of UiApplication it won't be shown on any home screen at all.
