but when tested layout on lg optimus l3 e400. red buttons not on position set.

the code of layout : 

<relativelayout xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:tools="http://schemas.android.com/tools"     android:layout_width="fill_parent"     android:layout_height="fill_parent"     android:background="@drawable/background" >      <textview         android:id="@+id/textview_navigationbar"         android:layout_width="fill_parent"         android:layout_height="wrap_content"         android:background="@drawable/navigationbar"         android:text="@string/string_map"         android:gravity="center"         android:textisselectable="false" />       <relativelayout          android:layout_below="@+id/textview_navigationbar"         android:layout_width="fill_parent"         android:layout_height="fill_parent"         android:layout_margintop="50sp"         android:layout_marginbottom="50sp"         android:background="@drawable/map">          <imagebutton             android:id="@+id/imagebutton_1"             android:layout_width="wrap_content"             android:layout_height="wrap_content"             android:layout_margintop="100dip"             android:layout_marginleft="50dip"             android:background="@drawable/button_1" />          <imagebutton             android:id="@+id/imagebutton_2"             android:layout_below="@+id/imagebutton_1"             android:layout_width="wrap_content"             android:layout_height="wrap_content"             android:layout_margintop="30dip"             android:layout_marginleft="6dip"             android:background="@drawable/button_2" />                  <imagebutton             android:id="@+id/imagebutton_3"             android:layout_below="@+id/imagebutton_2"             android:layout_width="wrap_content"             android:layout_height="wrap_content"             android:layout_margintop="1dip"             android:layout_marginleft="40dip"             android:background="@drawable/button_3" />      </relativelayout>  </relativelayout>

in lg optimus l3 e400 looks :

layout 2

the red buttons not on position. don't want use map view don't know , never used it.

please guide me how move out of problem. how create layout maximum resolution , screen support.

the easiest way create custom view holds image (bitmap) , buttons on top of it, , use ondraw method draw buttons, , analyse coordinates on ontouch create touch events.

if maintain image's aspect ration (width:height) can map buttons suitable location using scaling.

here list of custom views examples:

you can use andengine 2d graphics/gaming engine android, , take care of scaling you.

take here : official website , examples

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).
