Android开发sensor旋转屏问题解决示例

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

Previous Registrations:
17:57:12 + 0x0000002d pid=20420 uid=10265 package=android.view.OrientationEventListener samplingPeriod=200000us batchingPeriod=0us
17:57:12 + 0x0000002d pid=20420 uid=10265 package=android.view.OrientationEventListener samplingPeriod=200000us batchingPeriod=0us

相关sensor:

// 加速计传感器	handle: 0x0100000b
// app通常会注册回调 android.view.OrientationEventListener 此类内部注册了 加速计sensor,用来监听旋转角度

bugreport device_orient 信息查看上报事件

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:\&gt;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

bugreport 中:
