Isuseramonkey? Android really funny

QA reported a problem, said the wireless hotspot under the switch is gone, looked at the code, originally this is the protection mechanism of Android.

In the case of user information, Android will use Activitymanagernative.isuseramonkey () to determine whether a person is currently operating, and if not, some switches, functions are hidden and closed. If you try to run with the Monkeyrunner.bat in ADT, it will trigger the protection mechanism, and it appears that only a reboot is needed to recover.

android4.3 related code is as follows:

    public boolean Isuseramonkey () throws RemoteException {
         Parcel data = Parcel.obtain ();
        Parcel reply = Parcel.obtain ();
        Data.writeinterfacetoken (iactivitymanager.descriptor);
        mremote.transact (is_user_a_monkey_transaction, data, reply, 0);
        reply.readexception ();
        Boolean res = Reply.readint ()! = 0;
        data.recycle ();
        reply.recycle ();
        return res;
   }
