How to disable sleep mode ?o?

Hello,
It's quite easy,
You should use the PowerManager object to retrieve PowerService, then get the PowerManager.WakeLock object and ask for it. So in your Activity class declare the following attribute:

/**

 * The WaveLock object

 */

private PowerManager.WakeLock dimWaveLock;

/**

 * The tag to obtain the wave lock

 */

private static final String WAVE_LOCK_TAG = "MyLightLockTag";

In your onResume method, initialize and acquire the waveLock

// The phone should not go in sleep mode:

PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);

dimWaveLock = pm.newWakeLock(PowerManager.SCREEN_DIM_WAKE_LOCK, WAVE_LOCK_TAG);

dimWaveLock.acquire();

And in your onPause method, release the object:
//and also don't forget to accept the phone go back in sleep mode
waveLock.release();

And if you want to keep the brigthness of your application, do the same with the SCREEN_BRIGHT_WAKE_LOCK parameter :

/**

 * The WaveLock object

 */

private PowerManager.WakeLock dimWaveLock;

/**

 * The WaveLock object

 */

private PowerManager.WakeLock screenWaveLock;

/**

 * The tag to obtain the wave lock

 */

private static final String WAVE_LOCK_TAG = "MyLightLockTag";
....
/*

 * (non-Javadoc)

 *

 * @see android.app.Activity#onResume()

 */

@Override

protected void onResume() {

…

// The phone should not go in sleep mode:

PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);

dimWaveLock = pm.newWakeLock(PowerManager.SCREEN_DIM_WAKE_LOCK, WAVE_LOCK_TAG);

screenWaveLock = pm.newWakeLock(PowerManager.SCREEN_BRIGHT_WAKE_LOCK, WAVE_LOCK_TAG);

dimWaveLock.acquire();

screenWaveLock.acquire();

}

...

/*

 * (non-Javadoc)

 *

 * @see android.app.Activity#onPause()

 */

@Override

protected void onPause() {

...

// and also don't forget to accept the phone go back in sleep mode

dimWaveLock.release();

screenWaveLock.release();

}

So, Thanks who?
