Platform specific notes

Windows

The Windows backend is supported in Qt installations that were built with MSVC.

Android

The sensors provided by the Android backend can be read without requesting any Android permission.

The only restriction concerns the sampling rate of the accelerometer, gyroscope, and magnetometer. Starting from Android 12 (API level 31), reading these sensors at a rate higher than 200 Hz requires the android.permission.HIGH_SAMPLING_RATE_SENSORS permission. This is a normal permission that is granted at install time without prompting the user. If the permission is not declared, the sampling rate is capped at 200 Hz.

Declare the permission for the application with qt_add_android_permission:

qt_add_android_permission(myapp
    NAME android.permission.HIGH_SAMPLING_RATE_SENSORS
)

Note: When using a hand-written AndroidManifest.xml, it must contain the  tag for the permission to be added. See Qt Permissions and Features.
