[Vipul Amler]

Hi,
I had previously asked about it but dint get a reply, on the thread.
I was interested on working on Sympy for Android, anyone who I can
discuss this with?

I had posted a question on the thread but in vain. Perhaps i l submit
the full proposal here again,in case that thread doesnt go ahead.

Hi,

I repeat here the answer to Vipul sent today directly to him.

I support a SymPy GUI for Android totally written in Python SL4A,
but maybe the majority will choose a native (Dalvik) version for Android
(and the problem will be the Java communicate with Python/SymPy).

I am a mentor candidate to help the development of a SymPy GUI for
Android using Python SL4A.

Python SL4A (Scripting Layer for Android) is not full feature, for
example, there is no canvas, no line, point graphics.

My suggestions to about my mentorship subject :
- discuss about the SymPy GUI for Android in SymPy group;
- learn Python SL4A :
* SL4A site, search for Python :
http://code.google.com/p/android-scripting/wiki/Tutorials
Python SL4A webview GUI :
http://code.google.com/p/android-scripting/wiki/UsingWebView
* book "Pro Android Python with SL4A", 1st one about Python for Android,
I am using it :
http://www.apress.com/9781430235699
- learn SymPy;
- try to make until beginning of April a simple example using Python
SL4A with webview UI to show your capacity, maybe also using SymPy.

Thanks, will do and report back soon.

Hi Roberto,

I am working on an emulator. 2.2

I happen to have tried out sl4a for python, along with WebView. {The
example you listed and others, although dint check FullScreenUI}
Also sympy seems to work form within sl4a, properly {way slow on the avd}

So, I want to know what example you expect, or perhaps what I should be making?

Hi Vipul,

I don't like emulators, I develop directly (using Python) on
Android 2.2 (on Nokia N900 running NITDroid) and Android 3.2/4.0 (on
Asus Transformer). By the way, I develop directly on PDA, tablets and
smartphones since the Psion's days (1999 until today), from OPL to
Python, sometimes in C/C++ (on Maemo/MeeGo).

> So, I want to know what example you expect, or perhaps what I should be making?

My advice to you, sent 2 days ago, was : "try to make until

beginning of April a simple example using Python SL4A with webview UI to
show your capacity, maybe also using SymPy".

You can also mix Python SL4A webview UI with Facade UI, see my
Python webview template (with commented source-code) :
http://www.robertocolistete.net/Python/Android/

It is my first time trying to participate in GSoC (as a mentor), so
I think it would be better to also get the opinion from the SymPy community.

Regards,

Roberto

I agree with this advice.

After my submissions{last week, which consumed my time}, and scanning past the sl4a tutorials, I have got a bit of idea 

about the whole sl4a environment. Although  there is not much literature, {apart from the book ofcourse}, 

I could find scarce code example for sl4a webview

One, amongst them was Roberto's itself  from  over at [1], and other was this [2]

I was able to package Roberto's script into [3]  a full fledged apk, that calls the python script..

I am having issues in the callbacks to the html page from python script, which I am trying to figure out. {this is in reference to Roberto's script}

Moreover, initial lookout of mine was to get comfortable with sl4a, which I guess I have become for now.

I l be producing 1-2 examples to demonstrate sl4a Webview usage, from below

* Simple TODO Notes Manager

* Simple Calculator

* etc

I was not able to think of more examples.

Will send in the above demo's in my next mail.

About the GSoC Proposal, how should I be looking at it now?

I mean what features are to be envisioned, etc. I need to focus on this too for now, as the deadline ends soon.

P.S. The script from [3] successfully loads the sympy module in android, and makes use of it.

[3] https://github.com/vipulnsward/WebViewSL4A

[Vipul Amler]

The deadline is nearing so I have put in a draft proposal over at https://github.com/sympy/sympy/wiki/GSoC-2012-Application-Vipul-A-M-:-Sympy-for-Android . Please let me know any feedback so that I can make changes accordingly.

Hi Vipul,

Your work is interesting as packaging iOS and Android softwares is
not simple at all. By the way, on Maemo 4 & 5 OS and MeeGo Harmattan a
.deb file can be created on device (Nokia N810, N900, N9) using Python
scripts, it is a matter of editing one simple .py file. All my Maemo 4 &
5 packages were created using my Nokia N900 running py2deb.

There is a new software for Android, AIDE
(https://play.google.com/store/apps/details?id=com.aide.ui) which has
editor, java compiler and .apk packager running directly on Android. So
there is hope that Python .apk can be packaged on device (I will try it).

Could you better describe these issues so I can try to help you ?
