Android Question How to completely hide logs?

I'm ready to release my app in the google play store, but I dont'like that anyone can see logs generated by my apk.
Is there a way to completely hide this log? I already removed any log(....) from my code, but still remain other logs, as:

LogCat connected to: Q6VBBBB592805024
--------- beginning of crash
--------- beginning of main
** Activity (chat) Resume **
** Activity (chat) Pause, UserClosed = true **
** Activity (listautenti) Resume **
--------- beginning of system
** Activity (listautenti) Pause, UserClosed = false **
** Activity (chat) Create, isFirst = false **
** Activity (chat) Resume **
** Activity (chat) Pause, UserClosed = false **

I'd like a blank page...

Thank you
