support for different screen sizes in android -


i want apps support different screen sizes. add folders "layout-small , layout-large " in /res directory. xmls inside folders aren't accessible in activity.so add xmls in default layout , add code

if((getresources().getconfiguration().screenlayout &&        configuration.screenlayout_size_small) == configuration.screenlayout_size_small) {           setcontentview(r.layout.main1);     }else if((getresources().getconfiguration().screenlayout &&                 configuration.screenlayout_size_large) == configuration.screenlayout_size_large){                      setcontentview(r.layout.main2);         }         else             setcontentview(r.layout.main);

in activity, when avd skin 1024*600 , hw.lcd.dencity 160 (large) didn't work.

any help?

size: small, normal, large
density: ldpi, mdpi, hdpi,
nodpi(no auto-scale) aspect ratio: long, notlong
orientation: land

usage:

res/layout/my_layout.xml             res/layout-small/my_layout.xml       res/layout-large/my_layout.xml       res/layout-large-long/my_layout.xml       res/layout-large-land/my_layout.xml      res/drawable-ldpi/my_icon.png   res/drawable-mdpi/dpi/my_icon.png   res/drawable-hdpi/my_icon.png       res/drawable-nodpi/composite.xml

restricting app specific screen sizes(via androidmanifest):

<manifest xmlns:android="http://schemas.android.com/apk/res/android"> ... <supports-screens           android:largescreens="true"           android:normalscreens="true"           android:smallscreens="true"           android:anydensity="true" /> ... </manifest>

and code level tweeking: 

float scale = getcontext().getresources().getdisplaymetrics().density;

and don't forget:

dpi    = 160; //at 160dpi pixels = dips * (density / dpi)

also refer support multiple screen in android

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).
