Apps Camera2 Shutter Speed

[LordPato]

I'm trying to capture images with 30 seconds exposure times in my app (I know it's possible since the stock camera allows it).

But SENSOR_INFO_EXPOSURE_TIME_RANGE (which it's supposed to be in nanoseconds) gives me the range :

13272-869661901
in seconds it would be just

0.000013272-0.869661901
Which obviously is less than a second.

How can I use longer exposure times?

Thanks in advance!.
