How many times per second is the onDraw method called during animation?

The frequency of calling onDraw during animation depends on the device's screen refresh rate. On most modern Android devices, this rate is 60 Hz or higher (for example, 90 Hz, 120 Hz).

Accordingly, the onDraw method can be called up to 60 times (or more) per second if each frame rendering operation completes faster than the screen refresh period (approximately 16.67 ms for 60 Hz).

If rendering a single frame takes longer, the system may skip some onDraw calls to avoid lag and maintain smoothness.

Overall, during active animation, the system tries to call onDraw at a frequency as close as possible to the screen's refresh rate.
