My PC CONFIGURATION :
UBUNTU 11.10 version 64 bit ,
ECLIPSE 3.7 ,
ANDROID SDK
I tried hard to remove adb error but itsms not working and showing following Errors:
/platform-tools/adb:Error While loading Shared libraries
libncurses.so.5:wrong ELF class:ELFCLASS64
I even set all path for android set correctly but it wont works.
The elf (executable and link format) problem is due to your setup using amd64 and i386 stuff. The official Android SDK only runs on i386 JVM, so you need to manually specify the i386 JVM on Eclipse.
Sun(Oracle) 32-bit JVM. Here is a step-by-step on how to do this:Add the JVM to Eclipse. Navigate:
Put the location of the JVM. Probably will be

/usr/lib/jvm/java7/(my is/usr/lib/jvm/java-7-sun-1.7.0.01). The external libraries will be automatically added when you put the location of the JVM.Sun(Oracle) 32-bit JVM as default.
