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!!
  • Have you setup your $PATH variable correspondingly (to include the Android Emulator's directories which hold those executables)?

  • Thanks very much! I updated the $PATH variable and updated the question also.

  • Superb! But placing the answer inside the question is suboptimal :) Would you like to convert it into an answer (you can answer your own question, and are even encouraged to do so) -- or do you prefer me doing that?

The Error stating that the AVD's config is missing a Kernel file is because when I checked the AVD Manager, the concerned AVD had a red cross-mark against it! Once I repaired this AVD I found that the error was eliminated!


Need to add emulator -"$ANDROID_INSTALLATION/Android/Sdk/emulator" to your $PATH variable. after adding the path variable you will need to restart the terminal session. and / or you can permanently add the path variable by editing the bashrc/profile file depending your distribution.
