public abstract void onFrameMetricsAvailable (Window window, FrameMetrics frameMetrics, int dropCountSinceLastInvocation)
Called when information is available for the previously rendered frame.
Reports can be dropped if this callback takes too
long to execute, as the report producer cannot wait for the consumer to
complete.
It is highly recommended that clients copy the passed in FrameMetrics
via FrameMetrics.FrameMetrics(FrameMetrics) within this method and defer
additional computation or storage to another thread to avoid unnecessarily
dropping reports.
| Parameters | |
|---|---|
window |
Window: The Window on which the frame was displayed. |
frameMetrics |
FrameMetrics: the available metrics. This object is reused on every call
and thus this reference is not valid outside the scope of this method. |
dropCountSinceLastInvocation |
int: the number of reports dropped since the last time
this callback was invoked. |
