Prevent screen lock on dimming/standby while using android app?

Question

I'm developing an application and the last touch I need to put on it is preventing the screen to lock when the device goes into standby (screen off). The exact behavior as Google Navigation.

I'm wondering what, programatically I will have to use to keep this feature enable the entire time while using the app?

Answer 1

writing the following code to your xml file will prevent the screen from locking

android:keepScreenOn="true"

Answer 2

In the onCreate of your activity after the setContentView use this:

getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);

Not tried it myself.
