修改默认语言（系统本土化）
asop/build/target/product/core_base.mkPRODUCT_PROPERTY_OVERRIDES := \ ro.config.notification_sound=OnTheHunt.ogg \ ro.config.alarm_alert=Alarm_Classic.ogg \ persist.sys.language=zh \ persist.sys.country=CN不休眠
frameworks/base/packages/SettingsProvider/res/values/defaults.xml
里面60000改成-1，就是不进入休眠。
<integer name="def_screen_off_timeout">-1integer>还要修改以下：
修改 /frameworks/base/services/java/com/android/server/power/PowerManagerService.java文件
getScreenOffTimeoutLocked()函数:
if (mUserActivityTimeoutOverrideFromWindowManager >= 0) { timeout = (int)Math.min(timeout, mUserActivityTimeoutOverrideFromWindowManager); }+ if(mScreenOffTimeoutSetting < 0)+ return mMaximumScreenOffTimeoutFromDeviceAdmin; return Math.max(timeout, MINIMUM_SCREEN_OFF_TIMEOUT);去掉导航栏和状态栏
/frameworks/base/packages/SystemUI/src/com/android/systemui/SystemUIService.java

/frameworks/base/services/java/com/android/server/usb/UsbSettingsManager.java
默认返回true
