How to invoke an android device from sleep?

Question

In my application I have to enable the device 5 seconds after falling to sleepmode. I have tried different methods like

PowerManager powerManager = (PowerManager) getSystemService(POWER_SERVICE);
                WakeLock wakeLock = powerManager.newWakeLock(PowerManager.ACQUIRE_CAUSES_WAKEUP,
                        "MyWakelockTag");

But its not working. Anyone please help. Thanks in advance.

add these lines in your activity .

 getWindow().addFlags(
                  WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED
                | WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON
                | WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON
                | WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD);
