Is it possible to implement a custom way to lock/unlock an android mobile phone?
I know that in versions 2.1 from android and before, there was only the locking pattern available, and that in version 2.2 it is now possible to set a password as well, but what if i want to make a custom way of locking/unlocking it myself (such as recognizing handwriting, or making some different alternative method for the locking and unlocking process) ?
Is it possible to achieve this through an application? or would it be necessary to make a version of the Android OS based in the same source code but with changes within it?
If it would be necessary to make a different custom version of Android, can anyone give me any hints or tips as to how and where in the source code files are the blocking options considered?
Thanks in advance.
