example, a user is racing in a game or controlling a ball in the game ). In addition, the physical environment of the device is also reflected in the action of the device. For example, the user is driving normally, and the Android device is quietly lying in the seat next to it, although the device does not move, it will continue to vibrate as the car moves, and the device will also move as the car moves.In the first case, You can monitor the relative

Android open-source project Sensors The android open-source project (aosp) provides three software-based mobile sensors: gravity sensor, linear acceleration sensor, and rotation vector sensor. These three sensors are updated in android4.0 and both use Gyroscope (except for o

This example describes Android's ability to create an Android dynamometer using the sensor sensor to refresh the UI in a thread. Share to everyone for your reference, specific as follows: In the previous article, "Android based on sensor sensors to obtain gravitational indu

device's or application's frame of reference. In the second scenario, you need to monitor the movement of devices relative to the global frame. Generally, Mobile sensors are not used to monitor device locations, but they can be used with other sensors, for example, use a Geomagnetic sensor to determine the location of a device relative to a global reference system (for more information, see location sensor

In the second scenario, you need to monitor the movement of devices relative to the global frame. Generally, Mobile sensors are not used to monitor device locations, but they can be used with other sensors, for example, use a Geomagnetic sensor to determine the location of a device relative to a global re

Sensor_delay_normal the default speed of obtaining sensor data. Standard delay, for the general puzzle game or easy to use the game can be used, but the low sampling

Place your finger on the sensor on the back of the device. 6. The measurement results will be displayed after the measurement is completed. You can also select th

Ability to identify sensors and sensors The android sensor framework provides several methods that allow you to easily determine the sensors on the device during running. The API also provides several methods for you to determine the capabilities of each sensor, such as the maximum range, recognition rate, and power re
