android 设置 永不休眠

http://blog.csdn.net/lb5761311/article/details/50820671

如果想第一次烧录系统开机就是永不休眠。这个需要修改def_screen_off_timeout = -1，在Android 第一次开机的时候会去读取这个值， 

在文件SettingsProvider/src/com/android/providers/settings/DatabaseHelper.Java

<code class="hljs avrasm has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">loadIntegerSetting(stmt, Settings<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.System</span><span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.SCREEN</span>_OFF_TIMEOUT,

中将def_screen_off_timeout 保存在数据库中SCREEN_OFF_TIMEOUT
= def_screen_off_timeout，

读取数据中SCREEN_OFF_TIMEOUT 的值并更新到设置应用中。

这个函数会在设置时间有改动的时候被调用， 

mMaximumScreenOffTimeoutFromDeviceAdmin 为系统支持最大不休眠的时间 大概为2147483647 ，大概200小时 。远远超过我们的电池电量的时间。
