How to check the release date of an Android smartphone device?

Question

I want to measure properties like energy consumption of my Android application.

I know about tools like PowerTutor, but because I need a more accurate tool I want to use Qualcomm's trepn profiler. In Qualcomm's website, there is a list of devices that can be used for this purpose. However, in the (old, now-removed version of the) list there is also a release date for the devices.

How can I programmatically check the release date of a smartphone device? Is it possible to check the release date in Android device?

Answer 1

The only date I was able to find was android.os.Build.TIME. However, this is not the exact release date, it looks like the release date of firmware installed (though it is the release date in case no firmware upgrade took place).
