I want to make an app (for both Android and iPhone) where user puts some info to the app and that info (text) will be then permanently shown on a lock screen. Is it possible to make something like this? If yes, how please?
You can't show any info permanently on lock screen on iOS. There is no App Extension for that. But, something close to that can be done by creating Today Widget in iOS. The widget can be viewable even when device is locked. You just need to swipe down. For more info on creating it. Please look into the following tutorial:

Seems you can only add notifications. What you are referring to would involve jailbreaking.
Has anyone got experience with developing an application to replace the default lock screen? I've been told it is not possible, however this application manages it.
Any tutorials or guidance you know of would be appreciated.
100% possible. Here are some links to get you started.

I am new to android and I am trying to make a security based app in which I want create android lock screen which appears after clicking an item of list view.
Am I suppose to use the same lock screen code as available and make some changes?
I tried to search for my problem but couldn't find anything.
Thanks in advance .
See http://developer.android.com/guide/topics/admin/device-admin.html
I'm trying to make a screen with a pattern like Android Pattern Screen but not using it (I don't want lock my phone, only put a "private" section with a "door").
I need a screen to control the access a special section of my app so I have thought to use a pattern screen.
How can I do this? Where can I found a piece of code or and example?
Thanks :)
PD. The Screen I need is similar to this: http://www.actualidadgoogle.com/wp-content/uploads/2011/11/patron-desbloq-android.png
You can get the code from the android source. You can find the source here
I want do an app,i want it look the same as this one:
I don't know how to write the word "writing" as the red mark ,and how to add the app icon on
the screen.
The answer is simple and yet annoying: It is not possible using the standard lock screen. Source of Android's lock screen describes where to find the source code of the default lock screen, and if you look into the source code of LockScreen.java you will find out that this information is hard coded. So basically you will have to wait for a new Android version to support this feature or program your own lock screen, which kind of misses the point. :-/
I only found a comment in the docu here that it could be possible to add a widget to the lock screen sometime. Any than this I found some apps that deliver a complete alternative lock screen.
So my guess it, that the clock on your screen is only able to show the info on the lock screen due to an extra (HTC?)-API that is not available for third party developer as suggested here: https://stackoverflow.com/questions/3556430 too.
