I am new to tizen, I have just installed the latest IDE.

I have opened the sample systemInfo and run on the emulator. 

When i click the either of the button, it says “Exception: tizen is not defined”.

It seems i fail to access the device api.

Anything i need to do before using the device api ?

I have tried to set the privilege etc but it doesn’t work.

Anyone can give me some direction ? 

Thanks
