Early versions of Android included an explicit sensor type for orientation (Sensor.TYPE_ORIENTATION).

Most of the android devices have built-in sensors that measure motion, orientation, and various environmental condition. Motion Sensors; Environmental sensors; Position sensors; Some of the sensors are hardware based and some are software based sensors.

位置传感器Position Sensors. 6. Test for support. Android平台提供了两种决定设备位置的传感器： 地磁场传感器和方向传感器（the geomagnetic field sensor and the orientation sensor）。 还有一种传感器用于检测设备正面和其他物体的距离，叫做接近传感器（proximity sensor）。 Android Sensors Examples. Android Open Source Project sensors. Android Orientation Sensor监听方向. Using android sensor framework, you can implement in your android app the features that use sensors and its raw data. The following rotation modes are available. The android platform supports three broad categories of sensors. The Android Open Source Project (AOSP) provides three software-based motion sensors: a gravity sensor, a linear acceleration sensor, and a rotation vector sensor. Device orientation.

The android.hardware.SensorManager class provides methods : to get sensor instance, to access and list sensors, to register and unregister sensor listeners etc. Mar 31 Orientation Sensor Tips in Android Joshua Jamison I went through some pretty frustrating times recently trying to detect the physical orientation of the mobile device in Android recently so I figure I'll share my experience and what I learned here to … The orientation sensor was software-only, and it combined data from other sensors to determine bearing and tilt for the device. You can control screen orientation from notification area easily. Use sparingly. 关于Orientation Sensor在官方文档中的概述里有这样一句话： The orientation sensor is software-based and derives its data from the accelerometer and the geomagnetic field sensor.

You also can prevent the other application from changing screen orientation. Android sensor api provides many classes and interface. Android devices have a lot of sensors inside.

Android supports sensors which provide the measurements of certain properties such as device motion, orientation and rotation, pressure, temperature, light, magnetic field, proximity and humidity. The device orientation event returns rotation data, which includes how much the device is leaning front-to-back, side-to-side, and, if the phone or laptop has a compass, the direction the device is facing. android-rotation-sensor-sample. This is a sample application that uses the Android rotation sensor and displays the device rotation (pitch/roll) with a custom view (an attitude indicator, aka "artificial horizon"). Android SDK put on the hands of developers all the necessary APIs to take advantages of them and offer to their users applications that use them.

Don't update the UI on every orientation event; instead, sync to requestAnimationFrame. I happen to know the answer to this because I led the Android Sensor team for some time. 在使用方向传感器对手机方向进行监听的时候，如果使用到Sensor.TYPE_ORIENTATION，会发现已经过时了。不过好在官方提供了新的替代方法。即使用加速度传感器和地磁场传感器联合使用从而保证获取到手机方向。

- Auto Rotation: screen orientation is determined by a physical orientation sensor. March 16, 2018. Android Sensor API.

I checked the comments in this question, and it’s specifically referring to what happens on Android. In most cases, using these sensors is a better choice than using the accelerometer and geomagnetic field sensor or the orientation sensor. - Guard: this application prevents the other application from changing screen orientation. In this tutorial, you’re going to learn how to list all the sensors available on an Android device. The important classes and interfaces of sensor api are as follows: 1) SensorManager class.
