Answer 1

The blog guy himself posts this in the comments:

Hi guys, I found the problem and unfortunately my news is not good. I discovered that this technique only works for me because I use the security certificate of the simulator (the same certificate used by my device in my case). I researched and saw that there are two ways to use the API hidden:
– Put your application pre-installed into a system folder on the ROM
– Compile your application using the manufacturer’s security certificate
So this will just be useful for you if you will make an application to a specific device and you have the certificate of it, just like me. I apologize for not notifying it before, but I did not know that. I’ll update my post and I’ll warn about it at first. Thank you for the feedback.

What you want is not possible anymore without the phone manufacturers certificate or a rooted device.
