Android8.1 MTK 去掉锁屏功能

1、源码：

*****\vendor\mediatek\proprietary\packages\apps\SettingsProvider\res\values\defaults.xml

<string name="def_wireless_charging_started_sound" translatable="false">/system/media/audio/ui/WirelessChargingStarted.ogg</string>

//将false改为true即可，false锁屏，true不锁屏
<bool name="def_lockscreen_disabled">true</bool>

<bool name="def_device_provisioned">false</bool>
<integer name="def_dock_audio_media_enabled">1</integer>

2、源码：

*****\vendor\mediatek\proprietary\packages\apps\SettingsProvider\src\com\android\providers\settings\DatabaseHelper.java

loadBooleanSetting(stmt, Settings.Secure.ACCESSIBILITY_SPEAK_PASSWORD,
                    R.bool.def_accessibility_speak_password);
//将false改为true
if (SystemProperties.getBoolean("ro.lockscreen.disable.default", true) == true) {
      loadSetting(stmt, Settings.System.LOCKSCREEN_DISABLED, "1");
} else {
      loadBooleanSetting(stmt, Settings.System.LOCKSCREEN_DISABLED,
                        R.bool.def_lockscreen_disabled);
}

loadBooleanSetting(stmt, Settings.Secure.SCREENSAVER_ENABLED,
                    com.android.internal.R.bool.config_dreamsEnabledByDefault);

注意：改之前，需要根据自己的项目配置，看清楚用的是哪个目录下的SettingsProvider
