Error when first time Building apk

[spac3-monk3y]

I followed the installation doc as it says and when building my first android .apk I keep getting the following error output:

Command failed: tar xzf android-sdk_r21-linux.tgz

Buildozer failed to execute the last command
The error might be hidden in the log above this error
Please read the full log, and search for it before
raising an issue with buildozer itself.
In case of a bug report, please add a full log with log_level = 2

I'm running ubuntu 14.04 x86_64

My bad, the thing was that android sdk 'is not available in your country' (mine).

thanks
