Android开发sensor旋转屏问题解决示例

这篇文章主要为大家介绍了Android开发sensor旋转屏问题解决示例，有需要的朋友可以借鉴参考下，希望能够有所帮助，祝大家多多进步，早日升职加薪

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

<activityandroid: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=12021-08-09 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) {@Overridepublic 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=0us17:57:12 + 0x0000002d pid=20420 uid=10265 package=android.view.OrientationEventListener samplingPeriod=200000us batchingPeriod=0us

相关sensor：

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 17:50:25.68756344864486 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 statstimeRange="2021/8/21 08:14–18:08" packages

现场，命令方式查询当前activity：

adb shell dumpsys window | findstr mCurrentFocusdumpsys window | grepmCurrentFocus

查看包信息

adb shell dumpsys package com.eg.android.AlipayGphone$ adb shell dumpsys package com.android.stkPackages:Package [com.android.stk] (ac39f18):userId=1001sharedUser=SharedUserSetting{411f5ce android.uid.phone/1001}pkg=Package{fde9cef com.android.stk}codePath=/system/app/StkresourcePath=/system/app/Stk# apk 安装包位置legacyNativeLibraryDir=/system/app/Stk/libextractNativeLibs=trueprimaryCpuAbi=nullsecondaryCpuAbi=nullcpuAbiOverride=nullversionCode=31 minSdk=31 targetSdk=31minExtensionVersions=[]versionName=12# 版本号usesNonSdkApi=truesplits=[base]apkSigningVersion=3applicationInfo=PackageImpl{fde9cef com.android.stk}flags=[ SYSTEM HAS_CODE ALLOW_CLEAR_USER_DATA ALLOW_BACKUP ]privateFlags=[ PRIVATE_FLAG_ACTIVITIES_RESIZE_MODE_RESIZEABLE_VIA_SDK_VERSION ALLOW_AUDIO_PLAYBACK_CAPTURE DEFAULT_TO_DEVICE_PROTECTED_STORAGE DIRECT_BOOT_AWARE PRIVATE_FLAG_ALLOW_NATIVE_HEAP_POINTER_TAGGING ]forceQueryable=falsequeriesPackages=[]dataDir=/data/user_de/0/com.android.stk# 数据目录supportsScreens=[small, medium, large, xlarge, resizeable, anyDensity] ############timeStamp=2009-01-01 08:00:00firstInstallTime=2009-01-01 08:00:00# 首次安装时间lastUpdateTime=2009-01-01 08:00:00# 上次更新时间signatures=PackageSignatures{573d3fc version:3, signatures:[b4addb29], past signatures:[]}installPermissionsFixed=falsepkgFlags=[ SYSTEM HAS_CODE ALLOW_CLEAR_USER_DATA ALLOW_BACKUP ]

查看apk内部 AndroidManifest.xml

aapt dump xmltree C:UserslishDesktoptest.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 ，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.OrientationListenerprivate 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 ，这个直接使用的加速度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)DisplayRotationmCurrentAppOrientation=SCREEN_ORIENTATION_PORTRAITmLastOrientation=1mRotation=0 mDeferredRotationPauseCount=0mLandscapeRotation=ROTATION_90 mSeascapeRotation=ROTATION_270mPortraitRotation=ROTATION_0 mUpsideDownRotation=ROTATION_180mSupportAutoRotation=trueWindowOrientationListenermEnabled=falsemCurrentRotation=ROTATION_0mSensorType=nullmSensor={Sensor name="device_orientWakeup", vendor="xiaomi", version=1, type=27, maxRange=1.0, resolution=1.0, power=0.001, minDelay=0}mRate=2OrientationSensorJudgemDesiredRotation=-1mProposedRotation=-1mTouching=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=-1mUserRotationMode=USER_ROTATION_LOCKED mUserRotation=ROTATION_90 mAllowAllRotations=false# 正常 mUserRotationMode=USER_ROTATION_LOCKED mUserRotation=ROTATION_0mDemoHdmiRotation=ROTATION_90 mDemoHdmiRotationLock=false mUndockedHdmiRotation=-1mLidOpenRotation=-1mFixedToUserRotation=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

bugreport 中：

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;
