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. :(

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
