From your own link:

System.out.println() (or printf() for native code) should never be used. System.out and System.err get redirected to /dev/null, so your print statements will have no visible effects. However, all the string building that happens for these calls still gets executed.

In addition, at the beginning of that page, it says:

The rules below are not guidelines or recommendations, but strict rules. Contributions to Android generally will not be accepted if they do not adhere to these rules.

So DON'T do it!
