​

Methods

​

getResolution()

Resolution[] getResolution()

getMaxFrameRate()

float getMaxFrameRate(Resolution resolution)

Gets the maximum FrameRate for particular width and height. Platform internally uses some existing measurement points in idle condition to extrapolate framerate for particular width/heigh which should be treated as hint and may not be feasible in all the system conditions.

​

Parameters

resolution

Resolution — Required for which supported max frame rate is to be queried
