Android开发sensor旋转屏问题解决示例

2023-03-08 11:03:25 示例 解决 旋转

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：

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:
  Package [com.android.stk] (ac39f18):
    userId=1001
    sharedUser=SharedUserSetting{411f5ce android.uid.phone/1001}

    codePath=/system/app/Stk

    cpuAbiOverride=null
    versionCode=31 minSdk=31 targetSdk=31
    minExtensionVersions=[]
    versionName=12                    # 版本号
    usesNonSdkapi=true
    splits=[base]
    apkSigningVersion=3
    applicationInfo=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 ]

    timeStamp=2009-01-01 08:00:00
    firstInstallTime=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=false
    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：

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

        
        public static final int SHOW_ROTATION_SUGGESTIONS_DEFAULT =
                // SHOW_ROTATION_SUGGESTIONS_ENABLED;
                SHOW_ROTATION_SUGGESTIONS_DISABLED;
