Question

I have installed android SDK and android eclipse plugin successfully on Ubuntu 12.10. I created the AVD in eclipse, and now it's not running. This is the output error I receive when I run the AVD:it tips:

Starting emulator for AVD 'avd'
Failed to start emulator: Cannot run program "/home/sancai/android/adt-bundle-linux-x86_64-20130522/sdk//tools/emulator": java.io.IOException: error=2, No such file or directory

I find information via google, everyone says this is because my system version is 64, while the adt only support 32, to install: sudo apt-get install ia32-libs, when I installed the 32-bit library, other problems arise such as the library file association to other libraries, but has no other library files are fully，it tips:

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 ia32-libs : Depends: ia32-libs-multiarch but it is not installable
E: Unable to correct problems, you have held broken packages.

sancai@ubuntu:~$ sudo apt-get install ia32-libs-multiarch

Package ia32-libs-multiarch is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'ia32-libs-multiarch' has no installation candidate

Answer 1

This should help:

Go to xx/sdk/tools and run:

mv emulator emulator.bak
ln -s emulator64-arm emulator

No need to install any ia32 libs.
