android - setDisplayOrientation changes upon onResume() -


i'm using camera , have in portrait mode app 

camera.setdisplayorientation(90);

when activity goes background , comes display orientation 0 aka landscape, when try setdisplayorientation(90) again fails , throws error (possibly because final).

how maintain camera being in portrait aka 90degrees mode?

also have support 2.2 , higher can use api 8

per android api documentation, prior api level 14 not allowed set orientation while preview active: setdisplayorientation() reference.

i'm guessing need call stoppreview(), set desired orientation, , call startpreview().

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).
