Android Question Camera Exposure Time and ISO

[jrj]

I am developing an Android App to measure the radiation level using mobile camera which requires control on camera exposure time and ISO (sensitivity increases with exposure time). I could not find any camera class which can set exposure time or ISO in this forum. Does anybody have worked on it? Kindly help.

You can set the exposure with CameraEx.

It is also possible with Camera2 but will be more difficult.

Thank you very much for your prompt response.
I could find the following code in CameraEx class for setting the exposure compensation

Public Sub setExposureCompensation (expo As Int )
r.target = parameters
r.RunMethod2("setExposureCompensation", expo, "java.lang.int")
End Sub

But I couldn't find a method to set the exposure time.

I don't think that it can be configured with Camera 1 API. Might be possible with Camera2. It is not implemented in CamEx2.
