What steps will reproduce the problem?
Add the contents of «Using Wake Locks» to the full-screen example.
1. Add this lines into onCreate method (same after or before seting content 
view):
PowerManager powerManager =
      (PowerManager)context.getSystemService(Context.POWER_SERVICE);
wakeLock = powerManager.newWakeLock(PowerManager.FULL_WAKE_LOCK, 
       "My Lock");

2. Add «wakeLock.acquire();» and «wakeLock.release();» lines into onResume 
and onPause methods respectively.

What is the expected output? What do you see instead?
It doesn't works. Eclipse underline first «context» word and shows de error 
«context cannot be resolved».

What version of the product are you using? On what operating system?

Please provide any additional information below.
It's solved without «context.» in that line.
