RK3568 Android12 长按power键功能设置

问题
在测试Android12时发现，长按power键没有反应。对比Android11，是会弹出关机菜单，有emergency，power off和 reboot 这几个选项。

解决方案
frameworks/base/core/res/res/values/config.xml 中修改config_longPressOnPowerBehavior的属性值

简单分析
查了下这应该是Android12的新特性，长按关机默认功能是唤醒Google Assistant，我的机器中没有预装该应用所以就没有任何反应。
可以在Settings——System——Gestures——Press and hold power button中关闭Hold for Assistant功能，关闭后测试长按power键是可以直接关机，但没有出现任何提示。这样也不太好，最好是能和Android11的效果类似。

跟下settings源码
RK3568的Android12在这里：
packages/apps/Settings/src/com/android/settings/gestures/LongPressPowerButtonPreferenceController.java

可以看到getSummary() 的显示是根据getPowerButtonValue() 的值来判断的

@Override
    public CharSequence getSummary() {
        final int powerButtonValue = getPowerButtonValue();
        if (powerButtonValue == LONG_PRESS_POWER_ASSISTANT_VALUE) {
            return mContext.getString(R.string.power_menu_summary_long_press_for_assist_enabled);
        } else if (powerButtonValue == LONG_PRESS_POWER_GLOBAL_ACTIONS) {
            return mContext.getString(
                    R.string.power_menu_summary_long_press_for_assist_disabled_with_power_menu);
        } else {
            return mContext.getString(
                    R.string.power_menu_summary_long_press_for_assist_disabled_no_action);
        }   
    }   

getPowerButtonValue() 是获取POWER_BUTTON_LONG_PRESS_DEFAULT_VALUE_RESOURCE的值

private int getPowerButtonValue() {
        return Settings.Global.getInt(mContext.getContentResolver(),
                POWER_BUTTON_LONG_PRESS_SETTING,
                mContext.getResources().getInteger(POWER_BUTTON_LONG_PRESS_DEFAULT_VALUE_RESOURCE));
    }   

/**
     * Value used for long press power button behaviour when the Assist setting is disabled.
     * If this value matches Assist setting, then it falls back to Global Actions panel or
     * power menu, depending on their respective settings.
*/
private static final int POWER_BUTTON_LONG_PRESS_DEFAULT_VALUE_RESOURCE =
    com.android.internal.R.integer.config_longPressOnPowerBehavior;

RK3568的Android12在这里：
Android13.0/packages/apps/Settings/src/com/android/settings/gestures/PowerMenuSettingsUtils.java

这边可以看到最终是获取 config_longPressOnPowerBehavior 的属性值，该属性值是在frameworks/base/core/res/res/values/config.xml中定义，各个值代表的含义已注释得很明确了

<!-- Control the behavior when the user long presses the power button.
            0 - Nothing
            1 - Global actions menu
            2 - Power off (with confirmation)
            3 - Power off (without confirmation)
            4 - Go to voice assist
            5 - Go to assistant (Settings.Secure.ASSISTANT)
    -->
    <integer name="config_longPressOnPowerBehavior">5</integer>

测试属性设置为1,长按power键，出现如下界面，类似Android11的效果了
属性设置为2,长按power键，出现如下关机确认界面
这两个属性配置基本可以满足需求，问题解决

修改这里：
Z:\Android13.0\frameworks\base\core\res\res\values\config.xml

    <!-- How long to show a warning message to user before the device goes to sleep after prolonged
         user inactivity. -->
    <integer name="config_attentiveWarningDuration">30000</integer>

    <!-- Control the behavior when the user long presses the power button.
            0 - Nothing
            1 - Global actions menu
            2 - Power off (with confirmation)
            3 - Power off (without confirmation)
            4 - Go to voice assist
            5 - Go to assistant (Settings.Secure.ASSISTANT)
    -->
    <integer name="config_longPressOnPowerBehavior">3</integer>

    <!-- The time in milliseconds after which a press on power button is considered "long". -->
    <integer name="config_longPressOnPowerDurationMs">500</integer>

修改为：

    <!-- How long to show a warning message to user before the device goes to sleep after prolonged
         user inactivity. -->
    <integer name="config_attentiveWarningDuration">30000</integer>

    <!-- Control the behavior when the user long presses the power button.
            0 - Nothing
            1 - Global actions menu
            2 - Power off (with confirmation)
            3 - Power off (without confirmation)
            4 - Go to voice assist
            5 - Go to assistant (Settings.Secure.ASSISTANT)
    -->
    <integer name="config_longPressOnPowerBehavior">1</integer>

    <!-- The time in milliseconds after which a press on power button is considered "long". -->
    <integer name="config_longPressOnPowerDurationMs">500</integer>

【编译之后就修改了这里，原因未知！】
    <!-- Whether to only install system packages on a user if they're allowlisted for that user
         type. These are flags and can be freely combined.
         0  - disable allowlist (install all system packages; no logging)
         1  - enforce (only install system packages if they are allowlisted)
         2  - log (log non-allowlisted packages)
         4  - any package not mentioned in the allowlist file is implicitly allowlisted on all users
         8  - same as 4, but just for the SYSTEM user
         16 - ignore OTAs (don't install system packages during OTAs)
         Common scenarios:
          - to enable feature (fully enforced) for a complete allowlist: 1
          - to enable feature for an incomplete allowlist (so use implicit allowlist mode): 5
          - to enable feature but implicitly allowlist for SYSTEM user to ease local development: 9
          - to disable feature completely if it had never been enabled: 16
          - to henceforth disable feature and try to undo its previous effects: 0
        Note: This list must be kept current with PACKAGE_WHITELIST_MODE_PROP in
        frameworks/base/services/core/java/com/android/server/pm/UserSystemPackageInstaller.java -->
    <integer name="config_userTypePackageWhitelistMode">5</integer> <!-- 1+4+8 -->

修改为：

    <integer name="config_userTypePackageWhitelistMode">13</integer> <!-- 1+4+8 -->
