Hi folks,
Newbie here, and I expect some bashing as I don't know the rules, but I did saw similar questions so started a thread here.
So, I have decompiled an apk file, and I can see that there are folders in 'src', and after googling a bit I can find some libraries like rebound in the 'com' folder of the decompiled apk. But I couldn't find other libraries as someone suggested me on twitter that devs at times obfuscate things( not sure of the obfuscation!).
I am a business guy, I know less in-depth tech stuff and I am trying to do this for a market research initiative. Is there any easy way to find libraries? For example, I learned about XML and read the structure and got information on one more library present in that APK. Is there a way as easy as this one?
Or incase, if there's a more difficult way, I am ready to learn that no matter what level of difficulty it brings. Hit me up folks!
NOTE: I'm not trying to steal any one's work. This is just a market research work.
You should analyze source code and look for relevant JARs.
Also you can use a software like Charles (charlesproxy com). It analyses all the HTTP traffic on your network, so you can run the app and then monitor the HTTP packets on Charles to detect all possible GET-requests to APIs.

Thanks for the information. I will try doing that. But will also give me information on obfuscated libraries?
What kind of library did you mention? If you looking for native libraries, you can Use an app developed by Savier, named Native Libs Monitor. Search it on Play store.
Check out http://appbrain.com, they got quite nice analytics on apps, including libraries any given app using (under Basic Information -> libraries tab)

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
Sorry if this is the wrong place to post, but this is my first jump into android app development-
I'm *trying* to develop a cross platform gis data entry solution for editing shapefile/ geo-database polygon (or point) attributes in the field. Network connectivity can only be relied upon before going to, or upon returning from, the field. Is there an android friendly method for using a (any) type of geo-database file? Right now, I'm planning on exporting polygons to a kml/kmz or similar, and separately export the attributes to sqlite for editing. Upon return from the field, the edited sqlite rows can be used to update the (server-side) geo-database attributes.
However, I would eventually like to be able to directly edit the geometry, but am not sure if this means having to write something from scratch to read from a local geodatabase file, or if some sort of *local* android geodatabase solution already exists.
Just trying to get an idea of the initial direction I should be taking, as I have gis programing and database experience, but haven't ever done any native android development.
Any suggestions or links to related references would be appreciated!
Thanks!

I don't have any connection to that project.
I'll check it out- thanks. I also spoke with esri, and they will be releasing some android products soon, complete with apis. Certainly not ideal or open source, but probably cheaper than developing my own. Gonna keep trying to develop a simple solution for managing and edditing attributes on my own till then.

Hello! overflowers? I'm a beginner android developer and I have developed several apps that use the "basics" of android and java (for college requirements)
Now, I need to develop a new project that consists of making a web app which stores the records of all students from my college and the students will be able to check their records and other information from the college from their android phones.
I have done a lot of stuff with Android but I haven't done anything incluiding web queries, pulling info from a website to display into the device, etc etc.
So I want some advice here and/or tutorials that focus on this.
also, I have some important questions: 1. Can I pull information from the actual website from my college? If so, do I need to recieve some sort of permissions?
2. In case of not being able to pull information from the actual website from my college (for any reason whatsoever, like them not giving me permissions to do this), I could create a website that imitates its behavior, I would appreciate some tutorial or guide which could help me to achieve this.
Your help is very appreciated.
Btw, excuse if I'm breaking a rule here but something is not making sense to me.. the forum title says Q&A but when I mark this as a question it says this is not Q&A. I am aware this might be moved somewhere else but I dont know where.

I would look into hosting an sqlite3 database on a server, and access it to retrieve the data from within your app.
But the problem is, by default you cannot access an online database on Android, so you'll need to add some kind of RESTful interface, the easiest way probably being a php script which will retrieve the data from the database and return it into a JSON object for example, that you can then pull from within your app.
You'll need to expose some kind of syntax from your php script so that your app can request the data for a specific user (ie row X / column Y).
There's probably a better approach, but this is what comes to my mind.
This thread is for announcements and discussion around the WP8NativeAccess project (https://wp8nativeaccess.codeplex.com/). The purpose of this project is to provide general-purpose libraries, usable from C++ or .NET, which enable access to the underlying functions of the OS. In some cases, this will mean simple wrappers around native APIs; in other cases, these will be more advanced operations which simplify using the low-level APIs.
Some of the functions that the Native Access project exposes are already available via the official APIs. Other functions, however, are not. While I have no objection to these libraries being used in Store apps (license permitting), it is unlikely that Microsoft will permit the ones which use unofficial APIs.
Note that this library does not provide any method for elevation of privileges. Consequently, the use of these APIs will be constrained by the sandbox in which all third-party WP8 apps run, as defined by the capabilities in the app manifest. In practical terms, this means that most of the system will be either inaccessible or read-only. Even so, it has already proven useful to myself. When combined with interop-unlock and Capability-unlock hacks (making it possible for apps to obtain higher privileges), these APIs become much more useful. In fact, the EnableAllCapabilities utility uses the Registry library. Similarly, if you have the ability to use restricted Capabilities in an app you are developing, you may find these libraries useful.
The libraries are as follows:
FileSystem version 0.4.0: Implements functionality to read, write, and get information about files and directories, plus supports creating symbolic links and enumerating file system volumes. This version contains a breaking change from 0.3.x: the NativeFileSystem functions are now static and the constructor is removed. This library may be built with or without the macro USE_NON_PUBLIC_APIS; by default it now includes this macro and require kernelbase.lib to build. If this macro is not defined, it builds using the public APIs without requiring any special libraries.
Registry version 0.2.9: Implements functionality to read and write registry values, and to create and delete registry keys and values. Many, though not yet all, registry value types are fully supported. This library consists entirely of non-public (for WP8) APIs and requires the KERNELBASE.LIB and ADVAPI32LEGACY.LIB export libraries for Windows Phone 8 in order to build (the DLLs are in C:\Windows\System32 on the phone; you can use Dll2Lib.exe to extract the .LIB files).
Processes version 0.1.0: Implements basic functionality to get information about your process, and to create or kill a child process. Very early version.
They are licensed under the Microsoft Permissive License.
The FileSystem and Registry libraries are currently being used by my WP8 File Access Webserver project (http://forum.xda-developers.com/showthread.php?t=2355034).
My EnableAllSideloading app uses the Registry library (http://forum.xda-developers.com/showthread.php?t=2435697).
@hjc4869 has a basic FileExplorer app which uses the FileSystem library (http://forum.xda-developers.com/showthread.php?t=2497788).
You may need to use 7-Zip or another extraction program better than the built-in Windows Zip extractor to open the archive.
Reserved for OP...
Updated. This will be the main place on XDA for releases of the NativeAccess libraries going forward. Additionally, please report problems or make feature requests here.
I think there should be some way to list all the volumes...
Perhaps windows runtime has provided an async win32 file API wrapper which has the same ability as win32 ones ,so I think undocumented file API and registry ,process and etc are more important.
The latest version of the NativeFileSystem library can give you the mount points (as strings) for all volumes (C:\, D:\, etc.)... I implemented that a few days ago; it should be in this update. Sorry for not highlighting that more clearly (typo in the OP fixed now).
Can't open "NativeAccessLibraries_040_029_010.zip"
Edit Ok with 7-zip
How odd, you're right. I didn't do anything terribly fancy while building that ZIP, so I really don't know what's up with that.
I have added the NativeFileSystem library to my PDF to Office app...
Thanks again for all your work !
@GoodDayToDie: Congratulations, good work! Unfortunately I can't import the registry library, it says it's not a valid DLL. I have Visual Studio 2013 Pro. Does it work for WP8? Please help me solving the problem. Thanks!

You need to reference .winmd file, not the .dll file.
Thanks! Can we also modify hex registry values with it?

If you have the required permissions, yes. There's read/write functions for REG_BINARY, and also a simple wrapper around RegSetValue that will work for any type.
However, the library doesn't actually give you any privileges your app didn't already have. Without special Capabilities (which usually require hacks to enable), you won't have write access anywhere in the registry at all...

OK, thanks, but another question: I referenced .winmd file, but it gives me error, the component was not found. Any idea how to fix it?
Do you have the DLL and the WINMD in the same location? Are you creating a WP8.0 app (I don't know if apps targeting 8.1 specifically will work)? Are you building for ARM?
Yeah, I have. Library now working, but it doesn't recognize the commands, I mean if I write NativeRegistry.ReadDWORD command not found :/ Can you help me?
Sent from my RM-915_lta_lta_330 using Tapatalk
You're going to need to be way more specific.
How far did you get, i.e. can you compile the app? Install the app? Launch the app? Does it crash immediately or does it actually load? Etc.
What, *exactly*, breaks? Does it break when you try to reference the NativeRegistry library, or only when you try to actually use ReadDWORD function, or some time later? If you are able to call readDWORD, what is the return value? If it fails, what is the error code?
Are you getting an exception, or does it just not work? If it's an exception, give me as much detail about it as you can (the type, the message, the code where it happened, etc. if possible).

Hi, I can't even build it, it doesn't recognize the command and makes a red line under it. I can reference the library, but not use any commands like ReadDWORD, WriteDWORD and so on. Screenshot is attached, this is happening if I load your EnableAllSideloading App, for example. With self-created projects I have the same problem. My system is Win 8.1 Pro x64 and I'm using Visual Studio 2013 Professional. Can you help me? Thanks!
You have added
Registry.winmd in reference library
and
Using Registry;
in your source code
Source code for EnableAllSideloading already has the requisite using directives...
When you look in the project's References, is the Registry library referenced correctly? By default it'll try to use a relative path that I use on my PC, but probably not the same path you use. You may need to manually adjust the reference, or delete it and re-create it.
Alternatively, what auto-fix options does Visual Studio give you when you click on those red lines?

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

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.
