↳	android.os.PerformanceHintManager

The PerformanceHintManager allows apps to send performance hint to system.

Summary

Nested classes
	`Session` A Session represents a group of threads with an inter-related workload such that hints for their performance should be considered as a unit.

Public methods
PerformanceHintManager.Session?	`createHintSession(tids: IntArray, initialTargetWorkDurationNanos: Long)` Creates a `Session` for the given set of threads and sets their initial target work duration.
Long	`getPreferredUpdateRateNanos()` Get preferred update rate information for this device.

fun createHintSession(
    tids: IntArray, 
    initialTargetWorkDurationNanos: Long
): PerformanceHintManager.Session?

Creates a Session for the given set of threads and sets their initial target work duration.

Parameters
`tids`	IntArray: The list of threads to be associated with this session. They must be part of this process' thread group This value cannot be `null`.
`initialTargetWorkDurationNanos`	Long: The desired duration in nanoseconds for the new session

Return
`PerformanceHintManager.Session?`	the new session if it is supported on this device, null if hint session is not supported on this device or the tid doesn't belong to the application

Exceptions
`java.lang.IllegalArgumentException`	if the thread id list is empty, or initialTargetWorkDurationNanos is non-positive

fun getPreferredUpdateRateNanos(): Long

Get preferred update rate information for this device.

Return
`Long`	the preferred update rate supported by device software
