How to make the phone screen not standby in Android

On Android, applying for Wakelock can keep your process going even if your phone goes into sleep mode, it's useful to have a network function in the background, which can keep the operation going.

Method: Join before the operation

PowerManager pm = (powermanager) mcontext.getsystemservice (Context.power_service);
WakeLock = Pm.newwakelock (Powermanager.partial_wake_lock, Constants.tag);
Wakelock.acquire ();
Where Newwakelock has two parameters, the first parameter defines the behavior, the second parameter is the debug tag, which can be defined as the class name. The first parameter takes the following values:

flag Value	CPU	screen	keyboard
partial_wake_lock	on*	off	off
screen_dim_wake_lock	on	dim	off
screen_bright_wake_lock	on	bright	off
full_wake_lock	on	bright	bright

Don't forget to release it after the operation is complete.

if (wakeLock! = null) {
Wakelock.release ();
WakeLock = null;
}
Also, to add permission: <uses-permission android:name= "Android.permission.WAKE_LOCK"/>

Another way is to

1. @Override   
2. protected void onCreate (Bundle icicle) {
3. Super . onCreate (Icicle);
4. 
   
5. After testing this is still relatively useful, multimedia playback settings are not standby.
6. GetWindow (). Addflags (WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
7.     }  

This parameter also keeps the screen active and does not go into hibernation, saving some more than the previous security.
