In the project, the Android board needs to enter the desktop when it is turned on and never sleep. The project uses Fibocom’s SC806 Android development board and msm8909 platform.
Configure never sleep

Detailed description
Setting UI
First modify the setting -> display -> sleep menu array and add the Never option
File path: packages/apps/Settings/res/values/arrays.xml
Add the following two lines:
<item>Never</item>
--------------------------------------------------
<!-- Do not translate. -->
<item>0</item>
Turn off the screen pause function
File path: frameworks/base/packages/SettingsProvider/res/values/defaults.xml
Modify the value of def_screen_off_timeout to -1
<!-- <integer name="def_screen_off_timeout">60000</integer> -->
<integer name="def_screen_off_timeout">-1</integer>
Change the power management scheme
File path: frameworks/base/services/core/java/com/android/server/power/PowerManagerService.java
Add the following statement in the getScreenOffTimeoutLocked method:
private int getScreenOffTimeoutLocked(int sleepTimeout) {<!-- -->
int nosleep; // Add new
int timeout = mScreenOffTimeoutSetting;
if (isMaximumScreenOffTimeoutFromDeviceAdminEnforcedLocked()) {<!-- -->
timeout = Math.min(timeout, mMaximumScreenOffTimeoutFromDeviceAdmin);
}
if (mUserActivityTimeoutOverrideFromWindowManager >= 0) {<!-- -->
timeout = (int)Math.min(timeout, mUserActivityTimeoutOverrideFromWindowManager);
}
if (sleepTimeout >= 0) {<!-- -->
timeout = Math.min(timeout, sleepTimeout);
}
// Start new judgment
nosleep = mScreenOffTimeoutSetting;
if(nosleep == 0) {<!-- -->
nosleep = mMaximumScreenOffTimeoutFromDeviceAdmin;
return Math.max(nosleep, mMaximumScreenOffTimeoutFromDeviceAdmin);
}
//End of new judgment
return Math.max(timeout, mMinimumScreenOffTimeoutConfig);
}
private int getScreenDimDurationLocked(int screenOffTimeout) {<!-- -->
return Math.min(mMaximumScreenDimDurationConfig,
(int)(screenOffTimeout * mMaximumScreenDimRatioConfig));

Small modifications to the default environment modification plan
Modify the path: frameworks/base/packages/SettingsProvider/res/values/defaults.xml
Change the value of def_screen_off_timeout to 0.
Note: It is found that at -1, it will never sleep in the Chinese environment. If you select 15s in sleep in time, it will not sleep.
