Make sure that the 'emulator' file has executor permissions. use chmod +x emulator in that directory. – DaboRoss Jun 8 '13 at 3:34
souenzzo@VPCEG13EB:~/android-sdk-linux/tools$ chmod +x emulator souenzzo@VPCEG13EB:~/android-sdk-linux/tools$ ./emulator bash: ./emulator: Arquivo ou diretório não encontrado.... nothing has changed – Enzzo Pessanha Cavallo Jun 8 '13 at 3:39
That's odd. What's the output of ls -l | grep emulator? – Alaa Ali Jun 8 '13 at 6:25

You are trying to run 32 bit application on hybrid 64/32 bit system without basic 32 bit libraries. Check output of

uname -a
file emulator

You need to install 32 bit version of libc (i386) and some other other libraries that you will need. Check output of

ldd emulator

and install other 32 bit libraries.
