I know there are lot of questions like this in stack overflow, but i want know at this present date, still this problem did't solved ?
I saw this document for Sencha Touch 2 Native Packaging for Android and i tried it in my Ubuntu 12.4.
when i run this command sencha package run android.json
in terminal, I got
Sencha Cmd v3.0.0.250
[ERR] stbuild is not yet supported on linux
Then i searched and i come to that "Native packaging is not yet supported on Linux, only OS X and Windows at the moment."
my environment is Ubuntu 12.4, is there any solution? or i need to change environment (windows or mac environment).
