Android Emulator error libGL.so: cannot open shared object file: No such file or directory

If you run Android Emulator with the error of "libGL.so: cannot open shared object file: No such file or directory", you have to make link for libGL.so.

My machine run Ubuntu 12.04. The following is my solution to fix it. (assume libGL is installed in somewhere in your system)

- Locate your installed libGL:
$locate libGL

- make link to installed libGL.so
$sudo ln -s /usr/lib/i386-linux-gnu/libGLU.so.1 /usr/lib/libGL.so

locate and ln libGL.so

Remark:

~ If your system is 64 bit one, you must link to the 64 bit libGL
