RootTools 3.5
RootTools 3.5 brings official support for Android L.
It also brings support for context switching for ChainFire's su binary. (http://su.chainfire.eu/#selinux-contexts-unconfined)
You can find the available contexts in the enum Shell.ShellContext
You can set the default context (Shell.defaultContext)
You can open a shell by passing in a context to the getShell constructor
You can also switch the context of an existing shell by using the method switchRootShellContext (Using this method will close the current shell and re-open a root shell with the appropriate context)
