RK3288 Android7.1 永久关闭休眠功能

• 修改 Android 里面的源码，如下：

  • frameworks/base/services/core/java/com/android/server/power/PowerManagerService.java

  1863     private int getScreenOffTimeoutLocked(int sleepTimeout) {
  1864         int timeout = mScreenOffTimeoutSetting;
  1866         if(timeout < 0){
  1867             return mMaximumScreenOffTimeoutFromDeviceAdmin;
  1868         }
  

  • frameworks/base/packages/SettingsProvider/res/values/defaults.xml

   22     <integer name="def_screen_off_timeout">-1</integer>
   23     <integer name="def_sleep_timeout">-1</integer>
