audio - Creating an application that overwrite lock and unlock sound on Android -

-

i want create application able override lock.ogg , unlock.ogg android phone without needing root phone. don't know how code these nor if it's possible programmatically on android studio

here's basic idea:

  1. perform file searching obtain ogg files stored in phone.
  2. when user has confirmed sound, app copy file (so original file's name not overwritten), rename copied file lock.ogg/unlock.ogg.

the problem me other implementing ogg explorer, have code destination of new ogg file /system/media/audio/ui/ overwrite previous lock , unlock sound.

is possible using android studio?

i'm newbie on android studio.
