SecurityManager

public class SecurityManager
extends Object

java.lang.Object
↳	java.lang.SecurityManager

Legacy security code; do not use.

Security managers do not provide a secure environment for executing untrusted code and are unsupported on Android. Untrusted code cannot be safely isolated within a single VM on Android. Application developers can assume that there's no SecurityManager installed, i.e. System.getSecurityManager() will return null.
