配置文件在：frameworks/base/packages/SettingsProvider/res/values/defaults.xml

????falsefalse

直接將def_auto_time 和?def_auto_time_zone設(shè)置成false，就不會(huì)同步網(wǎng)絡(luò)時(shí)間了。

如果用戶去設(shè)置中去勾選，還是可以同步時(shí)間的，下面將把設(shè)置中的自動(dòng)同步選項(xiàng)移除，

移除packages/apps/Settings/res/xml/date_time_prefs.xml

-->

在packages/apps/Settings/src/com/android/settings/DateTimeSettings.java刪除有關(guān)獲取auto_time的ID的代碼。

如果覺得還是不放心，可以直接禁止同步時(shí)間的服務(wù)

frameworks/base/services/java/com/android/server/SystemServer.java

在這里找到NetworkTimeUpdateService把相關(guān)代碼注釋掉就可以。
