【Android 4.4 不休眠+不锁屏+默认中文+去除导航栏】白日放歌须纵酒,青春作伴好还乡。这篇文章主要讲述Android 4.4 不休眠+不锁屏+默认中文+去除导航栏相关的知识,希望能为你提供帮助。
1、不休眠frameworks/base/packages/SettingsProvider/res/values/defaults.xml里面60000改成-1,就是不进入休眠。这个文件还保存其他默认设置,如:"def_location_providers_allowed" translatable="true"> gps"def_location_providers_allowed_network" translatable="true"> network"assisted_gps_enabled"> true"def_netstats_enabled"> true"def_bluetooth_on"> true"def_wifi_display_on"> false"def_install_non_market_apps"> false"def_package_verifier_enable"> true"def_dim_screen"> false但是这个方法只适合于4.2以前的版本,4.4的版本还要修改以下: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); 2、移除锁屏功能./frameworks/base/packages/Keyguard/src/com/android/keyguard/KeyguardViewMediator.javaprivate boolean mExternallyEnabled = true把mExternallyEnabled 改成false。但是这只是改了开机默认值,用户还是可用disableKeyguard/enableKeyGuard来启动。为确保3rd app无法修改,/frameworks/base/packages/keyguard/src/com/android/keyguard/KeyguradViewMediator.java:private void doKeyguardLocked(Bundle options) {    ...    if (DEBUG) Log.d(TAG, "doKeyguard: showing the lock screen"); +         // showLocked(options); }3、修改默认语言/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=CN4.去掉导航栏\frameworks\base\core\res\res\values\config.xmlbool name="config_showNavigationBar"> true ------------> true和false控制开关。参考http://m.blog.csdn.net/blog/lcpajj/8850152
