Added the "never sleep" function in Android display settings.

Added the "never sleep" function in Android display settings.

Set def_screen_off_timeout to-1 in frameworks \ base \ packages \ SettingsProvider \ res \ values \ defaults. xml, that is
-1
Then modify alps \ packages \ apps \ Settings \ res \ values \ arrays. xml:

 
     
         
  
   15 seconds
          
  
   30 seconds
          
  
   1 minute
          
  
   2 minutes
          
  
   10 minutes
          
  
   30 minutes
          
  
   never
      
      
    
         
          
  
   15000
          
          
  
   30000
          
          
  
   60000
          
          
  
   120000
          
          
  
   600000
          
          
  
   1800000
           
  
   -1
      
 

Next, modify arrays. xml in the value folder of the comparison language and the translation corresponding to screen_timeout_entries. You don't need to care about the msgid, but google just uses it to indicate that it is his own resource. "Never sleep" You can.

Then the code changes:

Frameworks/base/services/java/com/android/server/power/PowerManagerService. java

private void updateUserActivitySummaryLocked(long now, int dirty) {..... //change code here ==============                      Slog.d(TAG,"mScreenOffTimeoutSetting ="+mScreenOffTimeoutSetting);                      //if (mUserActivitySummary != 0 ) {                if (mUserActivitySummary != 0 && mScreenOffTimeoutSetting > 0) {//change code here  end ==============                    Message msg = mHandler.obtainMessage(MSG_USER_ACTIVITY_TIMEOUT);                    msg.setAsynchronous(true);                    mHandler.sendMessageAtTime(msg, nextTimeout);                }
