Android開發(fā)sensor旋轉(zhuǎn)屏問題解決示例
更新時間：2023年03月08日 10:30:51 作者：拉普
這篇文章主要為大家介紹了Android開發(fā)sensor旋轉(zhuǎn)屏問題解決示例，有需要的朋友可以借鑒參考下，希望能夠有所幫助，祝大家多多進步，早日升職加薪
一、查詢 activity xml 配置screenOrientation信息：
找個測試機器，安裝此APP。as中 devices explorer界面中打開此apk安裝目錄，雙擊apk?；蛘甙補pk托到as中，在反編譯的資產(chǎn)xml文件搜索此activity，并查看 android:screenOrientation 屬性?；蛘呤褂?aapt dump xmltree 命令查看。
configChanges 屬性是為了防止重啟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、事件發(fā)生時間點分析：
事件發(fā)生時間點=錄屏文件名的時間 + 錄屏發(fā)生時視頻經(jīng)過的秒數(shù)
結(jié)合問題描述和usagestats服務(wù)的信息倒推事件發(fā)生時間點
三、logcat查看sensor激活狀態(tài)：
此log是高通 sensors-hal 層打印的
狀態(tài)欄--控制按鈕--“方向鎖定” 開啟時，en=0 即 sensor關(guān)閉！
/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是否注冊旋轉(zhuǎn)屏sensor
有的APP注冊的是加速度sensor，使用自己的算法計算
APP注冊 android.view.OrientationEventListener 回調(diào)，自身代碼調(diào)節(jié)旋轉(zhuǎn)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; // 手機平放時，檢測不到有效的角度
}
// 設(shè)置豎屏
if (((orientation >= 0) && (orientation <= 30)) || (orientation >= 330)) {
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
}
// 設(shè)置橫屏
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 注冊的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
相關(guān)sensor：
// 加速計傳感器 handle: 0x0100000b // app通常會注冊回調(diào) android.view.OrientationEventListener 此類內(nèi)部注冊了 加速計sensor，用來監(jiān)聽旋轉(zhuǎn)角度 // android.sensor.accelerometer public static final int TYPE_ACCELEROMETER = 1; 0x0100000b) lsm6dso Accelerometer Non-wakeup | STMicro | ver: 142870 | type: android.sensor.accelerometer(1) | perm: n/a | flags: 0x00000980 continuous | minRate=1.00Hz | maxRate=415.97Hz | FIFO (max,reserved) = (10000, 3000) events | non-wakeUp | highest rate level = 3, support shared mem: gralloc, 0x0100015f) lsm6dso Accelerometer-Uncalibrated Non-wakeup | STMicro | ver: 142870 | type: android.sensor.accelerometer_uncalibrated(35) | perm: n/a | flags: 0x00000980 continuous | minRate=1.00Hz | maxRate=415.97Hz | FIFO (max,reserved) = (10000, 3000) events | non-wakeUp | highest rate level = 3, support shared mem: gralloc, 0x5f676273) Gyroscope Bias (debug) | AOSP | ver: 1 | type: android.sensor.accelerometer(1) | perm: n/a | flags: 0x00000000 continuous | maxDelay=0us | maxRate=415.97Hz | no batching | non-wakeUp | // 方向傳感器---用戶app旋轉(zhuǎn)屏 handle： 0x0100010f // android.sensor.device_orientation public static final int TYPE_DEVICE_ORIENTATION = 27; 0x0100010f) device_orient Non-wakeup | xiaomi | ver: 1 | type: android.sensor.device_orientation(27) | perm: n/a | flags: 0x00000002 on-change | maxDelay=0us | minDelay=0us | FIFO (max,reserved) = (10000, 0) events | non-wakeUp | // 其 Wakeup handle： 0x01000110 com.android.server.policy.WindowOrientationListener 注冊此類型 0x01000110) device_orient Wakeup | xiaomi | ver: 1 | type: android.sensor.device_orientation(27) | perm: n/a | flags: 0x00000003 on-change | maxDelay=0us | minDelay=0us | FIFO (max,reserved) = (10000, 0) events | wakeUp |
bugreport device_orient 信息查看上報事件
# 0 表示通常的正常 # 1 表示順時針旋轉(zhuǎn)90度 device_orient Wakeup: last 10 events 1 (ts=68477.447943014, wall=17:49:58.724) 0.00, 2 (ts=68478.554363222, wall=17:49:59.831) 0.00, 3 (ts=68478.989033691, wall=17:50:00.265) 0.00, 4 (ts=68479.423711660, wall=17:50:00.701) 1.00, 5 (ts=68482.743111608, wall=17:50:04.022) 0.00, 6 (ts=68486.101931400, wall=17:50:07.379) 0.00, 7 (ts=68495.309003118, wall=17:50:16.585) 0.00, 8 (ts=68505.308247806, wall=17:50:26.584) 1.00, 9 (ts=68507.166153170, wall=17:50:28.444) 0.00, 10 (ts=68513.214244108, wall=17:50:34.491) 0.00,
六、有現(xiàn)場，查看當(dāng)前activity信息
logcat查看當(dāng)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}
根據(jù)DUMP OF SERVICE usagestats:內(nèi)容 查看時間點的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的結(jié)尾：
In-memory daily stats
timeRange="2021/8/21 08:14–18:08"
packages
現(xiàn)場，命令方式查詢當(dāng)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內(nèi)部 AndroidManifest.xml
aapt dump xmltree C:\Users\lish\Desktop\test.apk AndroidManifest.xml
七、App寫旋轉(zhuǎn)屏的幾種方式：
三種方式做旋轉(zhuǎn)屏:
大部分都是直接使用系統(tǒng)控制的，就是SystemServer進程注冊的 com.android.server.policy.WindowOrientationListener 監(jiān)聽，然后直接控制APP的界面旋轉(zhuǎn)，這個使用的 device_orient sensor。 但是因手機不同，廠商不同，有些豎直反向的旋轉(zhuǎn)，系統(tǒng)不準(zhǔn)旋轉(zhuǎn)。
// frameworks/base/services/core/java/com/android/server/wm/DisplayRotation.java // 內(nèi)部類： DisplayRotation.OrientationListener private class OrientationListener extends WindowOrientationListener // 在systemserver進程中是通過 com.android.server.wm.DisplayRotation$OrientationListener 操作
- 因此，大部分視頻app又會獨立注冊 android.view.OrientationEventListener 監(jiān)聽，這個監(jiān)聽直接使用的加速度sensor(android.sensor.accelerometer) 這個sensor直接返回0~360度的角度。然后APP根據(jù)角度，自己控制旋轉(zhuǎn)。此時“方向鎖定”不起作用。
- app直接使用 地磁+加速度 傳感器
八、bugreport 中 mUserRotation 信息
adb shell dumpsys window displays
dumpsys window displays | grep DisplayRotation -A 30
文件中搜索 mUserRotation=
WINDOW MANAGER DISPLAY CONTENTS (dumpsys window displays)
DisplayRotation
mCurrentAppOrientation=SCREEN_ORIENTATION_PORTRAIT
mLastOrientation=1
mRotation=0 mDeferredRotationPauseCount=0
mLandscapeRotation=ROTATION_90 mSeascapeRotation=ROTATION_270
mPortraitRotation=ROTATION_0 mUpsideDownRotation=ROTATION_180
mSupportAutoRotation=true
WindowOrientationListener
mEnabled=false
mCurrentRotation=ROTATION_0
mSensorType=null
mSensor={Sensor name="device_orient Wakeup", vendor="xiaomi", version=1, type=27, maxRange=1.0, resolution=1.0, power=0.001, minDelay=0}
mRate=2
OrientationSensorJudge
mDesiredRotation=-1
mProposedRotation=-1
mTouching=false # 觸摸屏幕情況下，不調(diào)用 DisplayRotation.java$OrientationListener 中的 onProposedRotationChanged 方法。即不會旋轉(zhuǎn)
mTouchEndedTimestampNanos=617520702367 # 抬起手時，機器開機以來的時間 如果當(dāng)前時間
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信息查詢 沒大用，只能查當(dāng)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 不會用于控制屏幕方向, 1 反之. _id:108 name:hide_rotation_lock_toggle_for_accessibility pkg:com.android.systemui value:0 default:0 defaultSystemSet:true

需要自己寫打點log
X、一些知識點：
亮屏是否默認(rèn)開啟旋轉(zhuǎn)屏sensor： 鎖定旋轉(zhuǎn)后，device_orient 這個sensor是否一直處于 enable狀態(tài)，google 默認(rèn)開啟
