Answer 1

For this version of sencha, for creating build, "st-res" directory is required.which contains AndroidManifest.xml , nimblekit.jar. And also have to make following changes in packager.json file.
"androidAPILevel":"14",
"sdkPath":"/home/.android-sdk-linux" /* path to android-sdk-linux */

Answer 2

I had the same issue so I simply upgraded Sencha on my machine:
$ sudo sencha upgrade
If you'll go for that remember to close and re-open your terminal window. Then when you use the above
command again and you should see something like:
Sencha Cmd v4.0.2.67
[INF] Determining the latest version of Sencha Cmd
[INF] The latest version of Sencha Cmd is 4.0.2.67
[INF] Sencha Cmd 4.0.2.67 is this version.
I hope this will help
