sms - Android unleavable activity -


i'm writing anti theft app, , want when sim card changed dialog opens on boot , tell finder bring phone. activity must unleavable, can't leave unless correct code entered.

other situation when user send lock sms phone.

i know how device admin can lock phone, lock don't tell message , password can't entered. , lock may not have password or pattern finder can pass easily.

maybe combination of device lock , full screen activity disable keyguard job?

in research, without being installed @ oem level, can't make 100% un-leavable, annoying.

in app wrote businesses use kiosk, since weren't @ oem level, kept menu bar hidden , set app loaded whenever home hit. keeping menu bar hidden pain, achieved making invisible , when re-triggered, making go away after 1 second. it's still able exited hitting clock in 1 second, though. :(
