Hello Martin and Umesh,
Umesh, Yes I would like to help you with this. I had created some JDBC wrappers
for SQLite connection. Maybe they can help you to get started.

Hello Umesh, and welcome!
Yes, there is remaining work to be done. A partial port to Android has been
done by Dinush during Google Summer of Code 2017 and is available there:
https://github.com/dinush/sis/commits/Android26
This work has not yet been merged to Apache SIS development branches however.
The reason is that the database accesses have been rewritten for using SQLite.
The use of SQLite is fine, but the replacement of every JDBC usage by
SQLite-specific API usage will make difficult to maintain this branch. A more
convenient solution for us would have been to use or create a "SQLite - JDBC"
bridge. If we could use SQLite through JDBC, it would allow us to have minimal
amount of changes on the development branch.
If you are interested in continuing this work, you are welcome! The next step
would be to look at Dinush commits and prepare a document that describe the
current state and why more work is needed. Note however we don't know yet if we
can have more than one student on Apache SIS this summer, so it would be safer
to prepare proposal for different projects in case.

Hello Weilun, Aditya, Sisinda, Buddhi and Dulaj. Thank Sisinda for your
proposal draft. For other people, if you are still interested in this project,
would you like to show a draft of your proposal before the deadline, so we can
comment on it if you want?

Hi, I am from final year of department of computer science and engineering at
University of Moratuwa. I have a good experience with Android development and
released several apps to the Google play also. I am very interested in
contributing to some Android related open source work now. This idea looks nice
to me, So I would like to start my contribution by selecting this project as my
this year GSoC project. I am now referring Apache SIS and will send a proposal
soon.

Hi,
I am a final year undergraduate of Computer Science & Engineering, University
of Moratuwa, Sri Lanka. I have experience on working in open-source projects
and I am really good at Android project development.
I find this project interesting and would like to contribute by selecting this
as my GSoC project.
Thank you.

{color:blue}Adapted from email thread: {color} For Google Summer of Code 2017
(GSoC), a next step would be to draft a proposal as described in the [student
guide|http://write.flossmanuals.net/gsocstudentguide/writing-a-proposal/].
Students can use any tools at their choice (GoogleDoc, Markdown in a Git
repository, OpenOffice, _etc._) and share the link either publicly on this
mailing list if you are fine with public review, or privately with the mentor
otherwise. We may need many cycles for improving the draft.
The proposal document should list the issues to resolve in this GSoC. Below are
some examples, but need student's review for evaluating if they are valid
issues, and if there is any other issues to resolve:
* Change the Maven project configuration for targeting Android.
* Either get JAXB support, or replace JAXB by something equivalent.
* Replace Java2D dependencies by equivalent classes from Android SDK.
* Port the EPSG dataset to the database engine supported by Android (SQLite).
* Provide a JDBC implementation sufficient for allowing SIS to use EPSG on
SQLite.
The proposal document should give more details for each issue and explain how
they could be solved. Note that Apache SIS does not yet have a graphical user
interface, so all above work is (for now) purely computational.
Finally, I strongly recommend that the student also submit other proposals for
different projects. Each GSoC student can submit up to 5 proposals. We always
receive much more proposals than the number of slots allocated by Google or the
number of mentors available, so putting all expectations on a single proposal
would be risky.

Hello Weilun. I just saw that the list of accepted organizations [has been
published|https://summerofcode.withgoogle.com/organizations/], and Apache is on
the list. Sorry for my mistake in previous comment. So now is the time to
discuss about projects, until April 3th. Aditya already posted an email on the
mailing list; I will reply to [that
thread|https://lists.apache.org/thread.html/b6a85ae93d59294215b6ca413c869ea2fccafce348f8301b7116b631@%3Cdev.sis.apache.org%3E]

Welcome Aditya! Would you like to contribute in the context of Google Summer of
Code (GSoC), or independently of GSoC? If you (or Weilun) want to contribute as
a GSoC student, we first need to wait for confirmation that the Apache Software
Foundation (ASF) is accepted for GSoC participation this year (ASF needs to
apply each year). If you would like to participate independently of GSoC, then
one possible approach could be to start a discussion on the Apache SIS mailing
list?
