In Swift 3.0 you can build Android apps in Linux but only console apps as
there is no framework to build GUI apps using JNI.
What I propose is to build an initial limited framework coded in C that
calls enough of the Java Android API via JNI to bootstrap the android app
and to create widgets and layouts.A default Androidmanifest.xml file and
some files needed to be generated to make a valid android app.
The Android API java surface is vast, so this framework needs to be build
over many releases to be useful. Developing a graphical Android app
requires interaction with "Activities" and the package manager and some
widgets like Button and some layouts like "RelativeLayout" and
"LinearLayout".
The result will be the ability to develop GUI Android apps on Linux using
Swift 3.0
Further support for additional APIs will be provided once the basics are
solid..
Who am I: Senior Android mobile developer with more than six years
experience on Android.
Am I able to build Swift 3.0 on Linux: Yes
Any help, suggestions, or ideas are most welcome
Warms regards,
Tony Constantinides
The swift-evolution process is primarily focused on the Swift language and standard library. Large-scale API development, which binding to/creating a GUI library entails, is out-of-scope for this process and should occur in a different forum.

It's not a cop-out. We would never include UIKit in Swift's standard
library, which is the set of definitions you get without so much as an
“import”. UI functionality simply belongs elsewhere.

Its a nice cop-out, but this framework is an extension of the standard library of Swift
Then it requires a proposal as much. Bear in mind that the Swift Standard Library is platform-agnostic. Adding support for Android necessarily contradicts that and will be a hard sell. Further, I don’t believe stdlib is the right target for this kind of library at all and will lead to the same lowest-common-denominator style of application as with Java on every other platform they support.
This doesn’t belong anywhere near core libs, but as a 3rd-party project it would certainly be welcome to have Android bindings.
as it will allow Swift developers to target new mobile platforms. This is the mailing lists for the evolution of Swift which is what this is. I not sure any of the other Swift mailing lists suits this goal. I not making Swift language changes(maybe) but adding an additional library that developers can build against if they are interested in having their Swift code running on Android.

https://github.com/apple/swift/blob/master/docs/Android.md
The main issue is that swiftcore is missing on Swift for Linux.
Unless Android gets support for Objective-C (shudder) I don’t think you need SwiftCore for this.
Its only important to understand I going to build this framework with or without support from Swift.org. However I want other developers to benefit from my work and I want to give back to the community. I find it extremely disappointing if Swift core members reject enhancing Swift to target additional mobile platforms as making Swift cross-platform is a stated goal.
I think this is a bit of a strawman. Members of this community have spent a lot of time and effort getting Swift to even build on Android. To say we’d “reject” this because it’s out of bounds for inclusion in the libraries you’re trying to include it in is ignoring the larger problems inherent in this proposal.

It’s disappointing that you seem not to understand what this mailing list is for. Building a Framework does not require the evolution process. It’s all up to you to open a GitHub repository and just start building.
Sure you can ask for help, but I believe other platforms like stackoverflow or even swift-users would be a better place for that.
And I think your statement about rejection is totally wrong. The core team has enough work and responsibility to care about.

Ok,
I was trying to follow the evolution process which states to "discuss your
idea on the mailing lists" before i begin work on it.That is what I am
doing. If you feel this work is not part of swift-evolution I shall bother
this group no longer. You have to remember I am very new to interfacing
with the Swift team hence the cautious approach. I do realize this is a
proposal and not a pitch and I am prepare to provide a great many more
details in a proposal. If you wish to point me to another swift mailing
list then please do so. If you feel this a "third party lib" then tell me
where it slots in. In other words be helpful and not react like a teen age
girl.
Of course I will begin development of this feature on github and give
talks to my local developer group. When I create a github with this
framework I going to have to add a licence. Making the software
copyrighted to my company and not link to the swift.org project in any way
seem odd to me. Not my idea of "open source" or contributing to a "major
open source project". You state that the Swift community members have spent
a great deal of time and effort in getting getting Swift to even build on
Android. Congrats! I here to take it to the next level.
If there is Swift community interest the code will be free via open
source. If there is none and judging by the response from the developers in
my "Bay Area Android Developer meetup group" that hard to believe then I
make it it commercial software to be sold.
Many thanks in advance.
Sincerely yours,

Ok,
Any other feedback from the Swift community other than it does not belong
as part of Swift? Or get the hell out of here?
I discussing this issue so people in the Swift community are aware of what
I am planning to do and have the ability to shape if they they so wish.
Some Technical points
Keep in mind when I say framework I do NOT mean a OSX like framework like
XCTest, I mean a third party library that doing two way communication with
your app.
a) It's not an Android Binding as that will not work, its a framework
wrapped up in a library using the bridging pattern
b) I want Swift to bootstrap the Android runtime indirectly when using the
framework. I want to make the Swift source the driving code and not the
Android Code. All events that the device sends out we be rerouted to Swift
code which will call the Java API using JNI in response
c) Android apps have a directory structure that must be maintained by the
framework to be valid. This will be handled by the framework.
d) Packages of Swift code will wrap the calls to the Java API which will
cause the need for a large library on the Swift side. The Swift developer
will use the Swift Library like any other and be unaware of its internal
routing to the Android API
e) This library will only work on Linux as there is where the Android
compilers are for ARM
Please provide input as it is welcome.
Right now I getting *crickets* which is not good.
I will be releasing a statement to the press when this work is working.
I want to state that the Swift Community actively supported it, including
Apple employees
I wish that statement to be true!

As others have said, this is outside of the scope of the current swift project. I’d suggest discussing this on swift-users and consider forming a new project around it. No one is trying to be mean about this, it just isn’t relevant to swift.org, which is why you’re not getting a lot of feedback.

Tony--
First off, welcome to the Swift community! Second, I think you're
misunderstanding the feedback here. The swift-evolution list is not a
mailing list for Swift community discussions in general. It's a mailing
list for proposals to change the core language (how do generics work? how
does control flow work? what about arrays, dictionaries, strings?). You'll
want to write to swift-users, or another forum where the Swift community is
active, to get feedback and participation about other libraries. If there's
something in the core language that you'll need to hook into to make
Android apps work better, then this is a great place to propose those
specific changes, and you could demonstrate a compelling use case by
describing how it enables critical features in your third-party library.
Cheers,
X
