PerformanceHintManager.Session Class

Definition

Namespace:

Android.OS

Assembly:

Mono.Android.dll

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

Remarks

A Session represents a group of threads with an inter-related workload such that hints for their performance should be considered as a unit. The threads in a given session should be long-life and not created or destroyed dynamically.

Each session is expected to have a periodic workload with a target duration for each cycle. The cycle duration is likely greater than the target work duration to allow other parts of the pipeline to run within the available budget. For example, a renderer thread may work at 60hz in order to produce frames at the display's frame but have a target work duration of only 6ms.

Any call in this class will change its internal data, so you must do your own thread safety to protect from racing.

Note that the target work duration can be #updateTargetWorkDuration(long) updated if workloads change.

After each cycle of work, the client is expected to #reportActualWorkDuration(long) report the actual time taken to complete.

All timings should be in SystemClock#elapsedRealtimeNanos().
