Android light sensor array data

Question

In the Android developer guide , when dealing with the light sensor, it says:

// The light sensor returns a single value.
// Many sensors return 3 values, one for each axis.

And then proceeds to take the first value of the array:

float lux = event.values[0];

In some cases, I get 0 in the first place of the array and a nonzero value in the second and/or third.

I tried to look for the meaning of this vector, but I couldn't find an explanation.

Can anyone please explain?

Answer 1

The data from the light sensor in lux is located in event.values[0].

Quite a few of the current Android phones have an RGB light sensor. In some cases the data you are getting via the second and third places in the array is related to that.
