Android 9 Development Cookbook - Third Edition

Position sensors

Position sensors include:

• Geomagnetic Field
• Proximity

The following sensor types use the Geomagnetic field:

• TYPE_GAME_ROTATION_VECTOR
• TYPE_GEOMAGNETIC_ROTATION_VECTOR
• TYPE_MAGNETIC_FIELD
• TYPE_MAGNETIC_FIELD_UNCALIBRATED

These sensors return three values in the onSensorChanged() event, except for TYPE_MAGNETIC_FIELD_UNCALIBRATED, which sends six values.

A third sensor, the Orientation sensor, has been deprecated, and you are now recommended to use getRotation() and getRotationMatrix() to calculate orientation changes. (For device orientation, such as Portrait and Landscape modes, see the next recipe: Reading device orientation.)
