You have three broadcasts available Intent.ACTION_SCREEN_OFF, Intent.ACTION_SCREEN_ON and Intent.ACTION_USER_PRESENT. First is pretty obvious. The other two are distinct in the way the user wakes the screen. If it is just a wake it is ACTION_SCREEN_ON, if it is followed by unlocking the screen Intent.ACTION_USER_PRESENT is launched too.

Make a broadcast receiver with a following intent filter:

        <intent-filter>
            <action android:name="android.intent.action.SCREEN_ON" />
            <action android:name="android.intent.action.SCREEN_OFF" />
            <action android:name="android.intent.action.USER_PRESENT" />
        </intent-filter>

Alternatively to get current state you can use Display.getState() and PowerManager.isInteractive()
