我要评论一、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

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:\>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;以上就是android开发sensor旋转屏问题解决示例的详细内容，更多关于android sensor旋转屏的资料请关注代码网其它相关文章！
