Android intercepting proxy - Java for Android App Development

Hi,
I'am thinking about building an Android intercepting proxy.
Main purpose is to intercept browser http traffic and modify it on the fly.
I just started Android programming and wonder if there are any projects for this idea.
Also I would like to know if anybody has some experience with intercepting traffic and which classes to use.
Greetz,

You can look at SandroProxy.

HTTP Server on WM6

Hi Guys!
I'd like to create a webserver on wm6 so I can contact to Localhost (127.0.0.1) to retrieve Phone info.
Purpose is a Flash app which uses GPS and Camera (Those or not accessable with actionscript)
I want the server to put GPS and Camera information on the localhost.
I know Freestyl (aka WhoNeedsAnIphone) uses a http server to pass some device variables to their flash app. But the project stopt and no code was released.
For Nokia Phone there's a Tool called KuneriLite to acces phone info with Flash.
I Also found Depeche But I don't really understand it....
Any Help/Code/App is welcome.

Hi, take a look here: http://goahead.com/products/webserver/download.aspx
I played around with it some time ago.
It has a lot of features like cgi and so on.
Nice Solution....
It Works but im more into C# then C++..
Is there a C# solution for this?
All help is welcome
Depending on how many of the HTTP verbs you really need to support (ie, do you just want to respond to a HTTP get for a certain url?) you could knock up a simple HTTP server in C# in an hour or two tops.
There's tonnes of examples of simple HTTP servers in C# on the web...
Sounds good,
But i'm only able to find C# webservers for PC, not for windows mobile...
The only thing the server has to do is respond from the code, so i dont have to load actual ASP/HTML pages...
Just a listener on Localhost, if i request localhost/req?GetVar=Cam
I can do something like WriteRespone("Cam=" + SomeSysVar)
Here you go
Attached is a C# simple http server application that I knocked up based on the MSDN sample at http://msdn.microsoft.com/en-us/library/bb397809.aspx.
I've not tested it on a phone.
The sample is for the compact framework.
Should work without any hassle.
Complete source included and the simplest parsing possible (currently responds to a http GET request for / with a chunk of HTML with "1" as the body).
Good luck, have fun.
(Oh and I just noticed there's a confusingly commented out line that says "write response" in the source, remove / ignore it.)
You can test the windows app from a web browser by pointing at http://localhost:83
edit:
apologies, i meant to close another thread.
Thnx Alot
Found this solution: http://bansky.net/blog/2007/10/compact-web-server-in-compact-framework/
It Worked for me ;-)
That looks like a good general purpose solution
My example is tailored towards specific custom processing over HTTP rather than serving of files -> in the style of a RESTful API.
From the look of it you can do a similar thing with the Compact Web server by hooking up what the author labels a "Special file type" and adding your custom handling code in there.
[edit]
That said, you could actually edit my example to File.Open whatever was passed as a parameter off the disk and stream that back to the client, providing a more standard HTTP server without configuration.
Nice simple solution u've got!
I will try to get it to work the way i want,
lookin' @ the amount of code it should be a lot faster then my previous solution.
Just noticed a very small bug. I'm refactoring the code to be a little better engineered. I'll upload a new sample shortly (you may have already managed to make use of it).
Right, I've re-engineered the code a little.
While the example now isn't contained in a single file, the source is now far more logical, readable and maintainable.
You'll notice the code that actually deals with the request is now hidden away in the HttpVerbs namespace.
Basically if you look at the file HttpGet.cs there's a good working example of how to implement whatever behaviour you like based off of a HTTP Get request to the server.
Code's pretty decent now, slightly more ready for prime time than previously, generally more type-safe and doesn't rely on string parsing all over the place.
Enjoy.
Binary?
Can you please put here binary (exe file) for Windows Mobile 6.1?
Thanks

TCP/IP Monitoring In Eclipse?

I'm a novice when it comes to Eclipse and Android programming, but I'm pretty familiar with Java and J2ME dev.
I've used the Network Monitor in the Java Wireless Toolkit and I'm trying to find something similar in Eclipse. Mainly, I'd like to see the requests and responses when I attempt to access web data.
What do you guys use?
Thanks,
Matt

API to programatically create wi-fi hotspot

All,
I'm new here. I've heard great things about these forums. I'm interested in developing an application that would require creating a wireless network from the device. I know this functionality is built into the OS, but I don't see an API to do this.
Can anyone point me in the right direction? If possible, I would like to have access to such features as SSID name, authentication type/password (I think I read WPA2 is the only one supported, which is fine) and channel.
I recall reading that Google would make public any API they use in their applications, so I imagine this would fall into that category (Froyo "hotspot" functionality).
Thanks in advance for your help.
Dan Bucholtz
Anybody? Bueller?
Theres no public API but you can use reflection.
Heres a class that does the job for you (also you can find an example Application there):

What Topic Do I Need To Tackle To Develop This Kind Of App?

The harvard university android app from google play store. (I can't seem to post any outside link yet for this account)
I want to create one for may school but I'm just starting to learn android programming, so guys I need your help on the topics that I need to study to create an app like that. I greatly appreciate any kind of comments. Cheers!

Fragments, ListViews, JSON parsing (for communication with the web server to download news etc), Android SQLite databases (I suggest using this to store the information from the webserver locally so the app does not require a constant internet connection to view a news article for example), Google Cloud Messaging notifications, notifications, encryption.
There are lots more but these are some of the main ones. In addition I would not advise trying to copy the "look" or aesthetics of the Harvard application as it frankly looks disgusting, whoever designed that needs a course in UI design
any book suggestions?? im only studying at home and wanted to start studying android app development

Android Application Development for Dummies and Learn Java for Android Development are 2 that I have in ebook form, though I can't say I've used them much as I don't really learn by reading books, more like looking at the source code of other apps and messing with it to see what happens
Android Application Development for Dummies goes through a wide range of topics including widgets, SQLite storage, possibly SharedPreferences (can't remember), ListView etc but does assume that you can at least follow what the sample code is doing - the sample code is commented but if you have not done any coding at all before then you probably should learn the basics of Java before reading it

When you get data from a server to an Android app you use php for the server code - for example you can use php/mysql to run a search for calendar events in the database and return those events. Then you need to use php's JSON encode function to send the data in a JSON array.
The output should look something like this - this is the output of the calendar database for my school:
http://wgsb.cobainschofield.com/android_db/get_calendar.php (note this is not the live schools site, its the test server the guy who maintains the live site allows me to mess with err use).
You would then use a JSON parser class and an AsyncTask from within the app to "download" the content of the JSON array and then display it in a listview or textview etc.
Now obviously to get this information requires an internet connection yes? So every time someone wanted to check for an event on the calendar or read a news article for example they would need a working internet connection to receive the output of the get_calendar script, this is inefficient and bad design as it does not allow for offline viewing of the data.
Therefore what you can do is use androids SQLite implementation to create a local sql database then the first time you need to get the data from the webserver, you connect to the internet and get the output of the php script, the using the JSON parser class you store the information in the sqlite database then get the information from the database to display to the user.
By this way users can view news articles or calendar events offline and you only need to connect to the internet to refresh the information
I've uploaded screenshots in the attachments of how I've done it for my school's app.
That made it clear! Thank you very much.

Has anyone used GoAppzone?

Hi I have been trying out a IDE GoAppzone, its a javascript html based approach to app development, and it provides easy to use connectors for accessing databases. I wondered if anyone on this forum has tried it out and what they think of it as a concept, and what they think of it as an IDE? GoAppzone.com
