[web2py] Re: web2py on android

[eric cuver]

you can use local storage for example :

var objet = { propriete1 : "valeur1", propriete2 : "valeur2" }; var 
monobjet_json = window.JSON.stringify(monobjet); window.localStorage
.setItem("objet",monobjet_json);

what if I need to store data in the mobile when there is no internet 
connection and sync with the webserver when there is connection?

what db or sqlite, can I use?

Hello,

Yes, you can write your backend Restful service with Web2py, and connect 
consumer web applications, android or iOS apps, etc.

I use to read ODoo web services, process data with Web2py and publish to 
customers with a Restfull service.
Web2py is perfect for this tasks. It is very fast and powerful to code the 
restful services and the web GUI is almost done out of the box.

Regards
Francisco.

You can use web2py for build a ret_api server and build your app with 
NativeScript (Angular2), ionic or reactnative

[Massimo Di Pierro]

Any web app can run as an android app or ios app. What the server side is 
written in irrelevant.

One of the easiest ways is to use gonative.io but it is not free. 

Everything you see in the article you mention works if you replace Flask 
with web2py.

I am sure other users have other recommendations.

[web2py] Re: web2py on Android

[xinx]

I am facing perhaps a similar issue when I try to get my web2py (Version 
2.5.1-stable+timestamp.2013.06.06.15.39.19) application running on a tablet 
with Android 4.3 and sl4a (python 2.6). GETs seems to be okay but POSTs 
(e.g. login as user) result in tickets. As any attempt to login results in 
tickets and is unsuccessful finally the content of tickets is not displayed 
in the browser but I manged to extract the complain:

(self=FieldStorage(None, None, ''))

When I add some python code to the cgi module function ' 
read_lines_to_outerboundary' to inspect self.fp ...

   while 1:
print 'DBG: fp - %s' % str(self.fp)
line = self.fp.readline(116)
if not line:
self.done = -1
break

 ... I get the following:

DBG: fp - open file 'fdopen', mode 'w+b' at 0x40b41ed0

Any help or hints how to track down the root cause of this issue are 
appreciated very much.

Regards,
Michael

 Web2py copies the input stream into a temp file in order to be able to 
 parse it but also pass a copy to the app. I suspect something happens to 
 the original stream and it gets closed twice (not sure why, not by web2py, 
 but by the wsgi adapter). If we isolate the problem we can find a work 
 around.

 Full web2py version (from git) has the same problem. 

 I have tried to detect the source of error with no luck. Has anyone run

 thoughts on this?. 

 Thank you very much. Greetings. Fernando.
