- 九、setting信息查询 没大用,只能查当前信息
- 十、用户点击状态栏“锁定旋转”行为分析:
- 十一、app调用 setRequestedOrientation 请求变更activity方向配置
一、查询 activity xml 配置screenOrientation信息:
找个测试机器,安装此APP。as中 devices explorer界面中打开此apk安装目录,双击apk。或者把apk托到as中,在反编译的资产xml文件搜索此activity,并查看 android:screenOrientation 属性。或者使用 aapt dump xmltree 命令查看。
configChanges 属性是为了防止重启activity
<activity
android:theme="@ref/0x7f130170"
android:label="@ref/0x7f1200c6"
android:name="com.miui.gallery.activity.ExternalPhotoPageActivity"
android:screenOrientation="4"
android:configChanges="0xda0"
android:showWhenLocked="true">
二、事件发生时间点分析:
事件发生时间点=录屏文件名的时间 + 录屏发生时视频经过的秒数
结合问题描述和usagestats服务的信息倒推事件发生时间点
三、logcat查看sensor激活状态:
此log是高通 sensors-hal 层打印的
状态栏--控制按钮--“方向锁定” 开启时,en=0 即 sensor关闭!
/vendor/qcom/proprietary/sensors-see/sensors-hal-2.0/framework/sensors_hal.cpp
logcat中搜索 device_orientation
2021-08-09 17:07:23.037 1021-1021/? I/sensors-hal: activate:209, android.sensor.device_orientation/272 en=1 2021-08-09 17:07:23.048 1021-1021/? I/sensors-hal: activate:220, android.sensor.device_orientation/272 en=1 completed
四、查看APP是否注册旋转屏sensor
有的APP注册的是加速度sensor,使用自己的算法计算
APP注册 android.view.OrientationEventListener 回调,自身代码调节旋转Demo:
private void registerOrientation(){
OrientationEventListener orientationListener = new OrientationEventListener(this) {
@Override
public void onOrientationChanged(int orientation) {
Log.d(TAG, "onOrientationChanged: " + orientation);
if (orientation == OrientationEventListener.ORIENTATION_UNKNOWN) {
return; // 手机平放时,检测不到有效的角度
}
// 设置竖屏
if (((orientation >= 0) && (orientation <= 30)) || (orientation >= 330)) {
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
}
// 设置横屏
else if (((orientation >= 230) && (orientation <= 310))) {
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
}
}
};
orientationListener.enable();
}
五、sensorservice 信息
DUMP OF SERVICE CRITICAL sensorservice:
bugreport dumpsys sensorservice信息查看 注册的sensor信息

六、有现场,查看当前activity信息
logcat查看当前activity: 有很多其他日志可供查看
07-31 17:50:25.687563 4486 4486 D Nav_RecentsImpl: onResumed className=com.miui.gallery.activity.ExternalPhotoPageActivity,mIsInAnotherPro=false,isKeyguardLocked=false,mNavStubView=com.miui.home.recents.NavStubView{f994da4 G.E...... ......I. 0,0-1080,35}
根据DUMP OF SERVICE usagestats:内容 查看时间点的APP
time="2021-07-08 09:29:02" type=ACTIVITY_PAUSED package=com.ainemo.dragoon class=com.meeting.call.activity.XylinkMeetingActivity instanceId=40437940 taskRootPackage=com.ainemo.dragoon taskRootClass=com.ainemo.android.activity.MainActivity flags=0x0
log的结尾:
In-memory daily stats
timeRange="2021/8/21 08:14–18:08"
packages
现场,命令方式查询当前activity:
adb shell dumpsys window | findstr mCurrentFocus dumpsys window | grep mCurrentFocus
查看包信息
adb shell dumpsys package com.eg.android.AlipayGphone
$ adb shell dumpsys package com.android.stk
Packages:

pkgFlags=[ SYSTEM HAS_CODE ALLOW_CLEAR_USER_DATA ALLOW_BACKUP ]
查看apk内部 AndroidManifest.xml
aapt dump xmltree C:\Users\lish\Desktop\test.apk AndroidManifest.xml
七、App写旋转屏的几种方式:
三种方式做旋转屏:
大部分都是直接使用系统控制的,就是SystemServer进程注册的 com.android.server.policy.WindowOrientationListener 监听,然后直接控制APP的界面旋转,这个使用的 device_orient sensor。 但是因手机不同,厂商不同,有些竖直反向的旋转,系统不准旋转。
// frameworks/base/services/core/java/com/android/server/wm/DisplayRotation.java // 内部类: DisplayRotation.OrientationListener private class OrientationListener extends WindowOrientationListener // 在systemserver进程中是通过 com.android.server.wm.DisplayRotation$OrientationListener 操作
- 因此,大部分视频app又会独立注册 android.view.OrientationEventListener 监听,这个监听直接使用的加速度sensor(android.sensor.accelerometer) 这个sensor直接返回0~360度的角度。然后APP根据角度,自己控制旋转。此时“方向锁定”不起作用。
- app直接使用 地磁+加速度 传感器
八、bugreport 中 mUserRotation 信息
adb shell dumpsys window displays
dumpsys window displays | grep DisplayRotation -A 30
文件中搜索 mUserRotation=
WINDOW MANAGER DISPLAY CONTENTS (dumpsys window displays)
DisplayRotation
mCurrentAppOrientation=SCREEN_ORIENTATION_PORTRAIT
mLastOrientation=1
mRotation=0 mDeferredRotationPauseCount=0
mLandscapeRotation=ROTATION_90 mSeascapeRotation=ROTATION_270
mPortraitRotation=ROTATION_0 mUpsideDownRotation=ROTATION_180
mSupportAutoRotation=true
WindowOrientationListener
mEnabled=false
mCurrentRotation=ROTATION_0
mSensorType=null
mSensor={Sensor name="device_orient Wakeup", vendor="xiaomi", version=1, type=27, maxRange=1.0, resolution=1.0, power=0.001, minDelay=0}
mRate=2
OrientationSensorJudge
mDesiredRotation=-1
mProposedRotation=-1
mTouching=false # 触摸屏幕情况下,不调用 DisplayRotation.java$OrientationListener 中的 onProposedRotationChanged 方法。即不会旋转
mTouchEndedTimestampNanos=617520702367 # 抬起手时,机器开机以来的时间 如果当前时间
mCarDockRotation=-1 mDeskDockRotation=-1
mUserRotationMode=USER_ROTATION_LOCKED mUserRotation=ROTATION_90 mAllowAllRotations=false # 正常 mUserRotationMode=USER_ROTATION_LOCKED mUserRotation=ROTATION_0
mDemoHdmiRotation=ROTATION_90 mDemoHdmiRotationLock=false mUndockedHdmiRotation=-1
mLidOpenRotation=-1
mFixedToUserRotation=false
九、setting信息查询 没大用,只能查当前信息
D:\>adb shell "dumpsys settings | grep rotation" _id:109 name:user_rotation pkg:android value:0 default:0 defaultSystemSet:true _id:17 name:accelerometer_rotation pkg:android value:0 default:0 defaultSystemSet:true # /frameworks/base/core/java/android/provider/Settings.java ACCELEROMETER_ROTATION # 0 表示 加速度sensor 不会用于控制屏幕方向, 1 反之. _id:108 name:hide_rotation_lock_toggle_for_accessibility pkg:com.android.systemui value:0 default:0 defaultSystemSet:true

- Label=方向锁定. State=2 表示 锁定
- logcat 搜索 “ send click msg ” 状态栏点击事件
- android_util_SeempLog.cpp 这个高通的log似乎未起作用
十一、app调用 setRequestedOrientation 请求变更activity方向配置
需要自己写打点log
X、一些知识点:
亮屏是否默认开启旋转屏sensor: 锁定旋转后,device_orient 这个sensor是否一直处于 enable状态,google 默认开启
/frameworks/base/core/java/android/provider/Settings.java
/**
* The default state of SHOW_ROTATION_SUGGESTIONS.
* @hide
*/
public static final int SHOW_ROTATION_SUGGESTIONS_DEFAULT =
// SHOW_ROTATION_SUGGESTIONS_ENABLED;
SHOW_ROTATION_SUGGESTIONS_DISABLED;
