License applicable for the modified Android source code

[Raghavan Santhanam]

Hi,

As part of an academic project I have taken the Android source from here and I have modified
it for the sake Samsung Nexus S device.

Now, since I am intending to contribute my project work to Android Open Source Project,
I would like to know whether I need to have a separate license or the existing Apache license
must be preserved with an option to include my name in the top Copyright comment stating
my exact modification in each source file.

I have also taken Android source from here and I have modified it for the sake of same
academic project work. I am intending to contribute these modified files as well to the
Android Open Source project. So, please let me know if I need to have a different license
or the existing Apache License must be preserved with an option to include my name
specifying what exactly I modified or what exactly my modification implements.

By the way, my work is on Sensor Emulation which emulates 10 sensors defined by
Android sensor subsystem. The real 5 sensors: Accelerometer, Magnetic, Light,
Proximity, Gyroscope, and the 5 virtual sensors: Corrected Gyroscope, Linear Acceleration,
Orientation, Gravity and Rotation Vector sensors.

For the sensor emulation, I had to write an entirely new source code from scratch intended to
be placed under <android_src_path>/hardware/libsensors targeted for the emulated Android.
So, please let me know the applicable license for this file and the related helper scripts like
Makefile etc under the same path.

Here are the demo videos of my work.
1) Real Android device scenario
2) Remote server scenario

For those who are interested, the details of the work are briefed in the description
of the above videos.

Thanks,
Raghavan

What Brian said.  And regarding attribution, in media we prefer attribution via git history not in source code.

Thanks Glenn. This sounds good now. I think I need to submit my work

as a patch explained as in here, right?
