Kivy Complete VM

[ZenCODE]

Greetings

This post serves to announce the impending upload of the Kivy Complete VM. The goals of this VM is provide a complete, flexible and fully functional run and build environment for Android. The idea is to remove any technical frustrations setting up Kivy or Buildozer, and have a VM that 'just works'. In my books, the technical barriers to building APK's is way too high. I want lower that.

Similarly to the official Kivy VM, this will be provided as a VirtualBox appliance. Main features include:

* Kivy 1.10.0 installed and running in Python 2.7.12

* Kivy 1.10.0 installed and running in Python 3.5.2

* buildozer 0.33 installed and out-of-the-box support for:
    * Android SDK 23
    * Android API 19

    * buildozer support for building both Python2 (hostpython2) and Python3 (hostpython3) APKs

The Kivy and Buildozer installations are built from source (github checkouts) into separate folders, so that master branch can be checked out and built/installed without complication. The VM in based on Xubuntu 16.04 LTS and includes a ReadMe.txt on the desktop explaining where things are and how to do stuff.

So, the question is where do I put this? Should it be uploaded to the kivy website? It's too large for my google drive and I have no personal hosting space. At over 10GB, it's not small and it contains many things you won't use. But you should be able to build and run kivy apps without issue (that is the goal, not minimalism). If you would find this VM useful, please also make a post here so we can gauge the need for such a VM.

Thanks and peace out

I would find it useful.   Getting Kivy to work on a Redhat machine is seemingly impossible.  So I use a VM myself for Kivy.

I'm a Fedora KVM virtual machine user. So while I understand the math behind the Oracle VM plus Ubuntu work station implementation decision, I am not willing or able to make the leap to this cirtualization toolchain.

My enterprise deployments revolve around Redhat's eco system. That means a heavy investment in KVM and or Docker techology plus Flatpacks, RPM's and the like.

Whatever deployment strategy is picked, if it can support the uoloading of additional VM's (aka KVM) this would be most appreciated. Not asking that you do the development by the way. I'd be willing to take a crack at converting the VM. The more difficult part would be in recreating this on another Linux desktop.

[yoav glazner]

I find it **very** useful! if you can find a place to store it would be great!

That's very nice and appreciated. In case the VM build process
involved only calling command line tools and not GUI interaction, could
you share those commands so that one can create a Dockerfile or a
Vagrantfile out of it?

Hi all

Thanks for the feedback. The VM is ready but I am really struggling to upload it. I'm trying mega.nz but just hangs on the upload. I'll try a different browser tomorrow, but also, living in Africa, we have pretty flaky connections. The image is 6.5gb and any break means you have to start from the beginning.

@Samuel Loury. The build command would be the standard bulldozer commands, so no should be GUI required.

Peace out

[Matthew Einhorn]

I'm not sure how much server space we have, dessant would know. But we can try kivy org google drive. Although that also has limited space. Is it compressible?

Torrent is also a good choice. I think tshirtman seeded it for previous VM versions.

Also, didn't Tito recently update the android VM? How is this different?

--

[ZenCODE]

@matham. It's already compressed during the 'Export appliance' process in VBox, so I doubt i will get much smaller. Yes, there is a new buildozer VM, but all of our devs (including myself) encountered multiple issues when trying to build as the VM still has to download the Android SDK and NDK and compile requirements. This seems quite fragile currently. Plus it cannot run a Kivy app.

This VM runs Kivy apps in Py2 and Py3 and has the SDK 23 / API 19 pre-installed with compiling an APK using these specs tested and functional.

Let me try mega.nz again with a different browser. If that does not work, I'll ask at the Python User Group meeting tomorrow if anyone can let me use their fibre connection for the task. And that gives me another chance to mention Kivy to them... :-)

[st...@btp.nl]

@zencode, can we at braintrainerplus help you?

[qua non]

Hi Zencode,

Most of the sms provided by kivy.org were able to run kivy directly, if the current one does not, then it's just a matter of installing the dependencies onto it.

My point is the vm on kivy.org is 1.2Gb compressed, adding kivy would at most add another 100 mb when compiled from source. 

I am confused on why your VM takes so much more,  perhaps you did not run zero free on it ?

[ZenCODE]

@Stas. Thanks for the offer. The uploading seems to work much better using Vivaldi (was using FireFox), so hopefully that works.

@qua-non. It was 9gb before zero-ing it. Keep in mind, it contains all the build tools (for Py2 + Py3), all dependencies, full checkouts of Kivy + Buildozer, the SDK, the NDK etc. My goal was not a small machine, but a complete one. With today's connectivity I don't think people will mind a few extra GB to avoid the complexities and installing and configuring Kivy/Buildozer. If size is an issue, they don't have to use this. Once it's available, it's post more details on what's inside it...

[Dave McCormick]

I am looking forward to a complete solution.  

The size does not matter as long as it works.

[Geekademy]

Just a random guy's opinion here so take with a grain of salt, but I'd drop the
Python 2.X support. It just doubles+ the complexity of everything.

Not to mention, no *new* projects should be started in Python 2. The EOL date
is now just over two years away. Supporting it means new projects will be
tasked with a potentially big porting (and kivy toolchain) upgrade shortly.

Not to mention your own time, which could be put to better use making the Python
3 support better.

I'm happy to say the VM is now available.

@Geekademy: It would be nice to go Python3 only, but that is not a deployment reality e.g. kivy-ios currently only supports python 2, so it's an unrealistic option for anyone wanting iOS deployment. But the VM supports both, so you are free to choose :-)

[Dave McCormick]

Thank you ZenCODE!!!!!  

I have it downloaded and it works!!

Just curious... which IDE or editor do you recommend / use when working with python / kivy ?

[Karla Muguerza]

You are a charm! Thanks a lot for this!

[ZenCODE]

@Dave McCormick. Definitely PyCharm, although it is rather heavyweight and slow to load. It's debugging and feature set is outstanding though. As a matter of interest, I also have a file with adds syntax highlighting to kv files...

Hi,

As someone who is writing a new app in Python3 and hoping to port it eventually
to iOS this is going to be a problem for me, and perhaps others. Previously it
was mentioned that the countdown clock on Python2 is already ticking and will be
here before we know it.

Is there a technical roadblock to Python3 on iOS, or just needs some time spent
on it?

I could fund some time on the project. Are there any others that want to join
and contribute either cash or effort to get Python3 working on iOS?

The savings in time from having to support Python 2 might help pay for itself as
well.

[Matthew Einhorn]

See https://github.com/kivy/kivy/wiki/Kivy-Python-2-Support-Timeline.

[Dave McCormick]

Is there a solution for SSL with Python 3 yet?

Hi all

I have been advised (by trusted parties), that hosting this on a trusted server is the only option. The VM could easily be modified, malware inserted, and offered as an alternative download location. Mega seems to be a dubious host...:-(

The most sensible option seems to have it hosted on an official Kivy server, and offered as an alternative to the official KivyVM. I am in the process of adding PyJnius support for Version 0.2 (amongst other improvements) and will explore this option when uploading. Other dev's would need to sanction and approve this for it to happen, but I doubt that will be a problem....

Peace out
Zen-CODE

[Dave McCormick]

If anyone wants the 0.1 version that Zen-CODE gave us I have a copy of it available.  Unmodified from when I downloaded it.

Once this is on an official Kivy server or when Zen-CODE makes version 0.2 available I will take this down.

Hi.

I do not understand a single thing in the Zen tutorial. When I want to generate the APK with Python 3 I must execute:

git checkout 1.10.0

And how much I want to generate the APK with Python 2 should I run:

git checkout master

Is this what the tutorial is saying?

Thank you very much !!

[ZenCODE]

No need for that. Everything is installed and funtional. You only need to use git if you want to update and build any of the kivy projects. But it is already installed and working for python 2 and 3.

[sac]

That would be awesome if you add Pyjnius with new version of Buildozer VM, thats solves most..

[ZenCODE]

@sac. It is :-) It's just taking me a while to get around to the Python3 Android deployment using Crystax. One's that's working, I'll upload a 0.2 version with a checksum (there was concern over 'rogue' versions).

In time, another interesting suggestion is to investigate building for Windows using Wine? @KeyWeeUsr? Not sure if that is feasible or legal, but it's worth asking the question I think....

[Pedro Sams]

I can not understand how I switch between the py2 and py3 versions without using virtualenv.

[ZenCODE]

python main.py
python2 main.py
python3 main.py

[ZenCODE]

md5 checksum added below the link. Thanks

[sac]

Looks really interesting :)

[sac]

Hi ZenCODE, It could be a silly question, but like to know if Kivy has any option to support Firefox OS phones, like we have for Android and IOS?

[ZenCODE]

I very much doubt it as FireFox OS has been discontinued.

https://en.wikipedia.org/wiki/Firefox_OS

It's theoretically possible, but I doubt it's worth spending that amount of time on an Operating System that has no future.

[sac]

I agree,  below is the reason I thought about it :) 

******************************

A fork called KaiOS have been used on a few feature phones, including Alcatel's OneTouch Go Flip^[63] (known as Cingular Flip 2 on AT&T^[64]), Reliance Jio's JioPhone(LYF F30C),^[65][66] and Intex's Turbo+ 4G.^[67] Primary features of the system is to bring support of 4G LTE, Wi-Fi, GPS and Wi-Fi with HTML5-based apps and longer battery life onto non-touch devices with optimized user interface, less memory and energy.^[68] They are launched by the company known as "KaiOS Technologies Inc." in the US^[69], with the company's president also being the president of the US branch of TCL Mobile.^[70] T2 Mobile, a branch of TCL Corporation, is also responsible for maintaining modules in the KaiOS.^[71]

*******************************

[ZenCODE]

@sac. Thanks for that. Very interesting. We should keep an eye on this to see what level of adoption occurs. Kivy is, by design, very portable. The real question  is: is it worth the effort? Let's see where this goes. If KiaOS proves popular, it may be worth supporting..,

[sac]

Hi ZenCODE,

Happy thanks giving :), just had a quick question with this VM, does it has hostpython2?

Thanks,
Sac

How are you ZenCODE?

I tried to use the new VM, but I got distribution error, it says my build is in ../platform/ path, but i dont see the platform folder created.

Cython==0.26 for py3 which is by default with this VM, not sure if i have to downgrade this. Please advise :)

Thank you so much ZenCODE, as the distribution error which got pasted below. It says Dist can be found in that location, but looks like platform folder is not created..Anyways will wait for the VM you are uploading :), thanks again

Yes, I cannot really test all requirements. Please make a new post with the full error log as these issues are not really related to the VM but (probably) the recipes themselves.
