Detect behind VPN in android -


how detect programatically if traffic going through vpn without using intent connect vpnservice. there system call?

the android os aware of when vpn connection active (as shows icon in status bar duration of vpn connection) there no public api method (which appear on vpnservice) check active connection.

two solutions occur. if dealing specific situation know network topology, run 'ping' see if particular ip address available - use system.exec. ping command present on android devices stock roms, i've used part of solution to provide more granular view of state of data connection (ip address not allocated, ip address allocated can't access internet, can access internet)

a better solution run traceroute instead , analyse output. i've not checked if traceroute present on android devices stock roms, i'll edit answer later more complete information.

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).
