Creating a simple virus program(harmless,just for fun / prank)....
This program can infect the phone as well as disinfect it....
(disinfecting will not function properly in some cases,data is not actually lost anywhere but you have to recover it manually in such case... **it is also described below)
so use at own risk....
Screen shot:-
After infecting
but yet it works in most cases
This posts include a simple program in android which is capable to invisible all the SD-Card content of phone from file manager,gallery and media scanner...
The basic idea behind it is only to hide/invisible the SD-Card content from phone.so Android OS gets unaware about that data and don't shows it up.....
In Android system folders having a dot "." as initial of its name considered as hidden .... so what we do is to make each SD-card folder to start with "..." to hide them ex- 'image' --> '...image'
and while disinfecting we have to remove those dots to unhide them from system....
