Public methods

getCpuUsages

Added in API level 24
open fun getCpuUsages(): Array<CpuUsageInfo!>

Return an array of CPU usage info for each core.

Return
Array<CpuUsageInfo!> an array of android.os.CpuUsageInfo for each core. Return null for each unplugged core. Empty if CPU usage is not supported on this system.
Exceptions
java.lang.SecurityException if something other than the device owner or the current VR service tries to retrieve information provided by this service.

getDeviceTemperatures

Added in API level 24
open fun getDeviceTemperatures(
    type: Int, 
    source: Int
): FloatArray

Return an array of device temperatures in Celsius.

Parameters
type Int: type of requested device temperature, one of DEVICE_TEMPERATURE_CPU, DEVICE_TEMPERATURE_GPU, DEVICE_TEMPERATURE_BATTERY or DEVICE_TEMPERATURE_SKIN. Value is android.os.HardwarePropertiesManager#DEVICE_TEMPERATURE_CPU, android.os.HardwarePropertiesManager#DEVICE_TEMPERATURE_GPU, android.os.HardwarePropertiesManager#DEVICE_TEMPERATURE_BATTERY, or android.os.HardwarePropertiesManager#DEVICE_TEMPERATURE_SKIN
source Int: source of requested device temperature, one of TEMPERATURE_CURRENT, TEMPERATURE_THROTTLING, TEMPERATURE_THROTTLING_BELOW_VR_MIN or TEMPERATURE_SHUTDOWN. Value is android.os.HardwarePropertiesManager#TEMPERATURE_CURRENT, android.os.HardwarePropertiesManager#TEMPERATURE_THROTTLING, android.os.HardwarePropertiesManager#TEMPERATURE_SHUTDOWN, or android.os.HardwarePropertiesManager#TEMPERATURE_THROTTLING_BELOW_VR_MIN
Return
FloatArray an array of requested float device temperatures. Temperature equals to UNDEFINED_TEMPERATURE if undefined. Empty if platform doesn't provide the queried temperature. This value cannot be null.
Exceptions
java.lang.SecurityException if something other than the device owner or the current VR service tries to retrieve information provided by this service.

getFanSpeeds

Added in API level 24
open fun getFanSpeeds(): FloatArray

Return an array of fan speeds in RPM.

Return
FloatArray an array of float fan speeds in RPM. Empty if there are no fans or fan speed is not supported on this system. This value cannot be null.
Exceptions
java.lang.SecurityException if something other than the device owner or the current VR service tries to retrieve information provided by this service.
