双击Power键会弹出Camer应用该怎样去解决呢

测试平台
Platform: RK3399/RK3328
OS: Android7.1/8.1/9.0/10.0


现象
双击Power键会弹出Camer应用,由于机器默认不带摄像头，所以需要关闭这个快捷操作


分析解决
跟踪代码发现,双击power流程是从PhoneWindowManager传入GestureLauncherService中，然后在GestureLauncherService中进行处理的。


//frameworks/base/services/core/java/com/android/server/GestureLauncherService.java
//frameworks/base/services/core/java/com/android/server/policy/PhoneWindowManager.java


PhoneWindowManager.interceptPowerKeyDown() ->
GestureLauncherService.interceptPowerKeyDown()->
GestureLauncherService.mCameraDoubleTapPowerEnabled-
GestureLauncherService.isCameraDoubleTapPowerSettingEnabled()




    public static boolean isCameraDoubleTapPowerSettingEnabled(Context context, int userId) {
        return isCameraDoubleTapPowerEnabled(context.getResources())
                && (Settings.Secure.getIntForUser(context.getContentResolver(),
                        Settings.Secure.CAMERA_DOUBLE_TAP_POWER_GESTURE_DISABLED, 0, userId) == 0);
    }


    public static boolean isCameraDoubleTapPowerEnabled(Resources resources) {
        return resources.getBoolean(
                com.android.internal.R.bool.config_cameraDoubleTapPowerGestureEnabled);
    }


由上可知道,控制双击Power 键功能的开关有两个:


com.android.internal.R.bool.config_cameraDoubleTapPowerGestureEnabled
Settings.Secure.CAMERA_DOUBLE_TAP_POWER_GESTURE_DISABLED
关闭其中一个即可实现需求


方案1：
关闭com.android.internal.R.bool.config_cameraDoubleTapPowerGestureEnabled
