将Android Sutdio升级到了3.6.0。现在，我的Manifest.xml文件中出现以下错误。
Expecting 'android:screenOrientation="unspecified"' or '"fullSensor"' for this activity so the user can use the application in any orientation and provide a great experience on Chrome OS devices.
此活动需要'android：screenOrientation =“ unspecified”'或'“ fullSensor”'，以便用户可以在任何方向使用该应用程序，并在Chrome OS设备上提供出色的体验
我应该将其转换为“ fullSensor”吗？我如何摆脱这个问题？
这是一种警告，告知开发人员对于大屏幕设备，限制方向是不好的。但是，如果您的应用程序仅支持纵向模式，则可以通过执行以下操作禁用此警告。Mac：Android Studio->“偏好设置”->搜索Chrome（我已经附上了相同的屏幕截图）->取消选中“活动已锁定到某个方向”->应用并确定。

screenOrientation
Added in API level 1
public static final int screenOrientation
Specify the orientation an activity should be run in. If not specified, it will run in the current preferred orientation of the screen.
This attribute is supported by the <activity> element.
Must be one of the following constant values.
| Constant | Value | Description |
|---|---|---|
| behind | 3 | Keep the screen in the same orientation as whatever is behind this activity. Corresponds to ActivityInfo.SCREEN_ORIENTATION_BEHIND. |
| fullSensor | a | Orientation is determined by a physical orientation sensor: the display will rotate based on how the user moves the device. This allows any of the 4 possible rotations, regardless of what the device will normally do (for example some devices won't normally use 180 degree rotation). Corresponds to ActivityInfo.SCREEN_ORIENTATION_FULL_SENSOR. |
| fullUser | d | Respect the user's sensor-based rotation preference, but if sensor-based rotation is enabled then allow the screen to rotate in all 4 possible directions regardless of what the device will normally do (for example some devices won't normally use 180 degree rotation). Corresponds to ActivityInfo.SCREEN_ORIENTATION_FULL_USER. |
| landscape | 0 | Would like to have the screen in a landscape orientation: that is, with the display wider than it is tall, ignoring sensor data. Corresponds to ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE. |
| locked | e | Screen is locked to its current rotation, whatever that is. Corresponds to ActivityInfo.SCREEN_ORIENTATION_LOCKED. |
| nosensor | 5 | Always ignore orientation determined by orientation sensor: the display will not rotate when the user moves the device. Corresponds to ActivityInfo.SCREEN_ORIENTATION_NOSENSOR. |
| portrait | 1 | Would like to have the screen in a portrait orientation: that is, with the display taller than it is wide, ignoring sensor data. Corresponds to ActivityInfo.SCREEN_ORIENTATION_PORTRAIT. |
| reverseLandscape | 8 | Would like to have the screen in landscape orientation, turned in the opposite direction from normal landscape. Corresponds to ActivityInfo.SCREEN_ORIENTATION_REVERSE_LANDSCAPE. |
| reversePortrait | 9 | Would like to have the screen in portrait orientation, turned in the opposite direction from normal portrait. Corresponds to ActivityInfo.SCREEN_ORIENTATION_REVERSE_PORTRAIT. |
| sensor | 4 | Orientation is determined by a physical orientation sensor: the display will rotate based on how the user moves the device. Ignores user's setting to turn off sensor-based rotation. Corresponds to ActivityInfo.SCREEN_ORIENTATION_SENSOR. |
| sensorLandscape | 6 | Would like to have the screen in landscape orientation, but can use the sensor to change which direction the screen is facing. Corresponds to ActivityInfo.SCREEN_ORIENTATION_SENSOR_LANDSCAPE. |
| sensorPortrait | 7 | Would like to have the screen in portrait orientation, but can use the sensor to change which direction the screen is facing. Corresponds to ActivityInfo.SCREEN_ORIENTATION_SENSOR_PORTRAIT. |
| unspecified | ffffffff | No preference specified: let the system decide the best orientation. This will either be the orientation selected by the activity below, or the user's preferred orientation if this activity is the bottom of a task. If the user explicitly turned off sensor based orientation through settings sensor based device rotation will be ignored. If not by default sensor based orientation will be taken into account and the orientation will changed based on how the user rotates the device. Corresponds to ActivityInfo.SCREEN_ORIENTATION_UNSPECIFIED. |
| user | 2 | Use the user's current preferred orientation of the handset. Corresponds to ActivityInfo.SCREEN_ORIENTATION_USER. |
| userLandscape | b | Would like to have the screen in landscape orientation, but if the user has enabled sensor-based rotation then we can use the sensor to change which direction the screen is facing. Corresponds to ActivityInfo.SCREEN_ORIENTATION_USER_LANDSCAPE. |
| userPortrait | c | Would like to have the screen in portrait orientation, but if the user has enabled sensor-based rotation then we can use the sensor to change which direction the screen is facing. Corresponds to ActivityInfo.SCREEN_ORIENTATION_USER_PORTRAIT. |
