Accessing depth camera via android sdk

I am kind of new to android developement and would like to use the data captured by the depth sensor of my phab 2 pro. (IR sensor) I know, that accessing the standard camera is possible via the Camera API using the camera2 class. But I do not know how to do so, or is it even possible, by using the phab 2's depth camera!? I already got familiar with the Tango C API but it does not provide the raw depth data, where depth is represented according to the image plane pixels.

Long story short question: Can I work with the depth camera of my smarthphone similar to the standard one?

Unclear why you need to access the depth camera via camera api when you can get access to the data in a Tango Point Cloud developers.google.com/tango/apis/c/reference/struct/… - Morrison Chang
I do not need the point cloud representation of the depth data. Rather I need the depth information as "raw" pixel data. Where each pixel of the image plane is assigned with a depth value (equal e.g. using the kinect) - mrks
There's no raw depth image from Tango's stand of point. All data comes from HAL is as points. stackoverflow.com/questions/41572682/… - xuguo
That tango url no longer works. - pete
You can find the SDK docs on archive.org. - Droid Coder

The best you can do is to capture a point cloud and use TangoSupport_upsampleImageBilateral() to interpolate the depth, for each pixel.

See:

Note that if you're trying to pair a depth image with an image from the color camera, they will possibly (always, in the case of the Yellowstone tablet) be captured at different times.
