I have installed android-sdk-linux on my ubuntu 12.04 netbook and I see that the commands android (which opens the AVD Manager) and emulator (to which on appending the name of a specific AVD, the AVD boots) are not found! It suggested qemulator But that turned out to have nothing to do with the android-sdk-linux.
I do know how to boot it via eclipse, where you open the AVD list and then select an AVD and click Start and then Launch.
But I don't want to go through these many stages. Instead I would like Launch it using a single command line viz. the emulator command, which I found on the website developer.android.com. I followed installation instructions. Yet I didn't get success.
UPDATE: As our friend suggested, I updated the $PATH variable and had partial success. However there is still an error and I have to get that rectified. Here is what panned out.
aneesh@nb-14:~$ export PATH=$PATH:android-sdk-linux/tools
aneesh@nb-14:~$ emulator @Andreud
emulator: ERROR: This AVD's configuration is missing a kernel file!!
$PATH
variable correspondingly (to include the Android Emulator's directories which hold those executables)?
