[Q] Do I need to write drivers? - Java for Android App Development

I have fair number of years of programming behind me. But I haven't tried anything for Android, as I dislike Java.
But I want to try. I want to make something that works at low level, say, like a firewall. It acts as a filter between two communicating parties/devices.
To write anything like that, can someone suggest which is the best approach - code in Java (if it can perform such a feast) or code driver in C?
Thanks much!

Nayan

The interesting thing in such low level projects is the entry point: So for a firewall you only have to acces iptables because android has linux kernel. So no C-part, no drivers, only plain java. See AFWall, it's an open source firewall.

Excellent! I would certainly study AFWall. Thanks for the reference.
But actually, my quest doesn't stop here. I am exploring Android, and Google's restriction of "UI to be built only via Java". (I am not interested in scripting and widgets for now, unless they are absolutely needed.)
I want to know the answers for same question (driver or app) for the following:
* Network Filter [EmptinessFiller, you already answered this as Java]
* Disk (SD cards) (for many various purposes) - file system should not block the intention, hopefully.
* USB filter
* SMS filter
I am still thinking of other categories. Will write more later.
Please suggest and refer. Thanks again!

General answer: Your app is always built in java. (It's UI components, it's LifeCycle (Activity, Service, Broadcastreceiver))
You may include native code, but that does not have more possibilities. It's only a little bit quicker.
Forgotten: If you have root, you may want to change some binaries, because you can't change things in an app. There you need native code of course.

Shame, isn't it? Too much power in Java's hand

My point exactly! Low level stuff is best written in native code.
But right now, I am learning how to.

Have a look at the Android NDK and this guide about the development of root apps.

Absuluut newbie, help on eMbedded C++ 4.0 please

Hello,
I'm a Visual Basic programmer for some time now.
Made some useful stuff they tell me.
Used C++ (Borland) about 10 years ago, so that’s a bit rusty.
Now I've ordered a Qtek 9090, and I would want to develop some software for it to. So I downloaded and installed the SDK and eMbedded C++ 4.0.
I thought, I start out on the emulator......
I can't even get my own "Hello world" program to work........
I have downloaded a "Hello World" program which I stepped through in debug mode. I have NO idea what they are doing there.
It contains about 20 files, hundreds lines of code, just to put "Hello World" on the screen of the emulator.
And I hoped that:
Code:
#include <stdio.h>
main()
{
printf("Hello, world!\n");
return 0;
}
pleased in a form, would do the trick………
The help in the IDE does not work.
Re-install it tell's me. I have done so, but the help function does not work.
Where is the "visual" part in the embedded Visual C++?
How do I place forms and buttons e.g.?
I have no idea where to start now.
Searched a lot of forum's for starters-help, but I can not find anything that helps me on my way. I just hope I've not become stupid.....
Would somebody please help me on my way?
Can I wholeheartedly recommend the book "Programming Windows CE", by Douglas Boling? It's normally cheap (or the second edition is) on ebay and it really is good.
Failing that, you're writing a console based application for something that uses a windowing environment by default, so you'll either have to change what you're linking to, or have a winmain that makes use of a graphical UI rather than stdout. Call MessageBox perhaps? This is all made *so* much easier with a working help system that you need to get that working.
You can manage resource files visually, so it really is Visual development. Plus, for free, it's an excellent development tool. Well, it isn't bad.
The best advice I can give is to get your machine set up correctly with EVC2002, or EVC 4 with SP4 and the appropriate SDKs, and take it from there.
Good luck starting out.
Cheers,
Nick.

Well, yes. I know. Like I sayed, I usualy work with VB. It was just me, trying to oversimplify things.
What I ment to express is that I'm pretty supprised I still have to write the message-loop and the main-loop and the jsadgkh-loop and....
I just hoped to put up some forms and attach code to it. But maybe I'm missing the clue on this.

And a 'free' tool. Well, that's allways nice. I think it is good for us, AND good for them. The more software there will be on the market, the better the devices sell.

Dox, drop me a PM, I've got an old copy of the book you can have if it would help
Re the message loop stuff, you've indeed got options. You can either use the message loop approach hitting the API directly, or you can opt for using MFC to abstract the stuff away from you.
Personally, I prefer the straightforwardness of using the API rather than MFC. By the time you've written one application, you've got the bulk of the next . I also write for older machines, and the overhead of MFC is a consideration, but on the XDA it really isn't.
If the application is simple, it can all be handled by a DialogBox. You will need to write a DialogProc to handle the appropriate messages, but the need to register a window class, get messages off the queue etc is removed from you. Similarly, you can have multiple pages on a single dialog box using propertypages.
If you did want to write a console application, you can do this but you need to change the linker options within EVC.
Have a good look at the samples, too, there's some real good stuff in there.
Cheers, and good luck

What language and software uses android for programming?

Hey guys im considering porting/recoding an app from VB.net to work on android, but i havent got a clue what language is used in android, could someone tell me its name or some sort of website with this information?
Finally if someone is experienced in programming apps for android, i would like to chat about a few capabilities of the language.
Thanks in advance!
Android is Java-ish based.
i would recommend you checking out the program Eclipse.
The main applayer is java based with some xml thrown in. But there is a native development kit that you can compile c c++ and many other languages to run on an android phone. But since java is virtual machine based an app written in java will run on all phones*(some caveats like os version) while the app in ndk will work on only hardware that it was designed for
Also, is Google not working? A simple search for "Android programming language" would answer this question

hmmm, yes there is google but not what im exactly asking, and that makes me ask this:
You talk about c & c++ and other languages compilations to run on android phone, is vb.net a part of that list?
Could you show me a website or something that says more about that dev kit? im basically trying to port my apps from vb 2010 express (windows forms based) to android and if that thing is not possible should i use java to code it all over again?
Thanks in advance!
http://developer.android.com/sdk/ndk/ this is for the ndk but it is not as simple as just compiling your code with the ndk. You will need to rewrite some of it to actuallytie into the android apis
You should really just use the java sdk. You will reach more people and be able to find more help and info
And I stand corrected, while there are projects trying to bring other languages to the ndk it is at this point just C and C++

oh well in that case i will need to learn java.... thanks mate, i think its easier to just rewrite the whole thing really i like proper optimizations and ports most of the times lack them.
Thanks for the information thats all i needed.
PS: rep added
if you know vb.net well you'll have no real problem with java.. it just adds brackets and semicolons essentially lol. I learned java in college and then was thrown into the .net framework using c# and i love the .net framework.. its so hard for me to go from using Visual Studios to Eclipse to make an android application because Visual Studios (which im assuming you use, is so powerful).. But yes android is java code behind and html (preferred) GUI. You can make your GUI using java but trust me its terrible!

You can use Javascript+HTML5 (it's complicated to express here but the whole things is pretty much native).
Python aswell, use SL4x or Kivy (Kivy is pretty good but it's still too new).
Sorry, being hate Java too much.

No you dont need javascript or html5.
Android has a ui layout system based in xml. Its just there to arrange objects that you can access from the java code. So a little xml and java is all you need

The right way to do GUI is with Java, with the official SDK from Google.
Some non-standard way to do this is with Javascript (just a GUI wrapper from Javascript to Java) and Python (again wrapper to Python).
You can choose which way you want, many people I know didn't like Java, and they choose to use a web application, and then they want to embed this to a native Android application, so they go with Titanium Mobile or some others framework like that. It's not as good as Java, but it's some other way to start with your application (Web app first and then Native app)

well ive been learning vb and i will admit that im still on intermediate level, even though i know all the basic stuff such as messing with its own functions, etc i still havent used any of the apis for it, the main problem with programming is that if u learn a language you would waste your time learning that one or else if u go learn to many languages you will end up not knowing none of them at all.
Ill see if i can mess with java, some people say syntax is a bit similar to c & c++
EDIT: btw, im not saying i dont find java good, a programming language that will basically run on any machine independently of the OS makes the language itself possibly the best and most versatile around.
I'm learning Android and I use Java and XML. I'm still a beginner though.

[DEV] AndroidLib - .NET Android Device Communication and Management Library 01.20.13

Description:
AndroidLib is a .NET assembly written in C# (C-Sharp) that easily handles communication between a connected Android device and your program. Currently, there is a large amount of automated controls, eliminating thousands of lines of code the programmer has to write themselves. The class AndroidController is a semi-wrapper of the ADB (Android Debug Bridge) binary. The other class you will be working with the most is the Device class. This class contains useful information about the device (for example: software/hardware info, memory info, battery stats, mount points for partitions, root status, busybox information, and much more), as well as exposes many instance methods to control your phone such as Rebooting, Mounting Filesystems, Push/Pull/Install Files, and much more to come. AndroidLib contains all of the Android binaries necessary to work properly. AndroidLib also assumes that the phone's USB drivers are already installed correctly on the target machine, or that your program will take care of it on it's own.
This is perfect for any developer who would like to create, for example, an auto-rooter or any other application that needs to connect with Android devices through a .NET application. AndroidLib provides all the methods needed to communicate with the Android device. This will cut back on the code you have to come up with and write yourself by a HUGE amount!
What it does:
Provides easy-to-use code for communicating with Android devices in .NET
Provides easy access to information about the connected Android devices
Has a large list (and growing...!) of methods that control connected Android devices
Please credit the work here by me in your own projects; not only to give thanks to me and the many hours I am putting in to this project, but so others know where to find it if they need to!
Usage:
Add a reference to AndroidLib.dll in your .NET project and begin using this great API. Please refer to the "Getting Started.txt" guide and full documentation included in the zip.
Requirements:
.NET 3.5 or Higher

It's very useful, thank you very much, im planning to code a Filemanager like qtadb, because qtadb is sucking too often
In the process of completely redesigning the library (due to coding stupidity), basically from the base class up. I should have a beta1 out by this weekend for testing. All that are interested in beta testing this library for their Android .NET projects, post here and I'll add you to the list of testers!
It would be great!
Can you add something like adb forward? So we can connect to an android service without using ADB, that as we all know sucks!

Yeah, I'll throw in a method to create a port forward. What I have now uses the bridge, which is included in the assembly, but handles all of it silently and very well. I should have a build out soon (most likely this weekend). As long as you don't dispose the AndroidController object, that port forward will be good, so you can use your own Socket code

Making some last minute changes to the Device class, then I'm going to finish the documentation and release it. Just keeping you updated.
Ok everyone, the new documentation is up (Online) (Offline). For the beginning of this product, I would like developers to pm me, or reply here in the thread if they would like to try the library out for their project, and I'll send it to them. It's still under development, and there will be updates coming out regularly. Shoot me a pm or post here and I'll send you a link right away.

Hey guys, check the first post to download the library. It is in a zip which includes the dll, "Getting Started.txt" and the documentation. Please read the getting started guide before diving into it! And please give me feedback on it. That would be much appreciated in order for me to deliver a better product.
Dan
Great work!
It works without any problem to me!
Next update will have these features internally implemented:
Package Manager (inside the phone's shell)
Ability to install/uninstall apks
Ability to freeze/unfreeze apks
Ability to backup/restore apks
A class that will handle signing of update zips
More internal information about connected device (cpu, environment, etc)
Possible wrapper of AAPT
That seems like a good amount for the next update. Please post anything you wish to share about the library after using it for these few days.

[HELP] Analysis tools that detect common bugs in Android app development

I am looking for analysis tools specific for Android app development!
I have found many tools online that are not specific for Android, only for Java, either free or commercial, like the famous FindBugs but it is not interprocedural so for example it loses several bad NullPointerExceptions that may occur at runtime! Other tools (like CheckStyle) perform just a syntax check that sometimes is not so powerful, and other tools are not suitable for Android app development
What are, among the available tools, those that you prefer and really use?
What kind of properties do these tools check?
What kind of bugs do these tools detect and remove (among the most common errors that an Android developer may do)?
Please help me with sharing your experiences and suggestions, thanks!
Nobody uses any tool for detecting bugs?
What kind of bugs are you specifically looking for? Solving NullPointers is hard to do automatically, it'll probably just show you where the error is and what it is.
And the emulator/logcat does that, too...

If you run FindBugs in your source code, it is able to detect many things, like potential NullPointerExceptions, before running your app...but unfortunately it is not powerful enough to detect interprocedural NullPointerExceptions...that's the reason I am looking for something different...

Yep, that's what I meant. Anyhow, I don't know about anything like it .
The Android SDK provides some API for automatic testing.
You will need to create a test project which checks the functions you want to achieve.
This can be used to ensure that your app is still working correctly after adding new features.
Hi
"static analysis tools" is probably the term you want to be using when looking for these sort of tools, the wikipedia page give a good selection to be going on with http://en.wikipedia.org/wiki/List_of_tools_for_static_code_analysis
Although I would add that if you're getting a lot of these sort of errors then you probably need to work on your own code writing skills and take the time to understand how and when these sort of issues occur rather than just relying on a plethora of tools which keep you dumb to what's going on! You'll benefit from it in the long run
One thing you might give a try is JetBrains Android Studio. It seems to have a decent static analysis tool which is the same used for ReSharper with Visual Studio.
Try Lint, it comes with ADT,
with Eclipse you can right click your project, ans under android tools you will see something like check lint errors
It will create lots of errors, which are just recomendations, you can simply delete those errors.
Tapatalked... just Tapatalked...
If you're mainly looking for a way to detect NPEs then IntelliJ/Android Studio comes with NPE (and other exceptions) detection. It's based on a new set of annotations implemented in the latest SDK and is very accurate, much better than Eclipse's code analysis.
But honestly, the best tool to find bugs remains Logcat imo, it's verbose enough to find-out the origin of most bugs.

Help Developing An App

Morning all,
I have never created an app, but decided to look into it late last year. I began work on an app around September 2014, did a little work every weekend, and haven't really touched anything since November.
I have experience with HTML, CSS etc (I can write them). I can also have a basic understanding of other codes such as PHP, JavaScript, Java, C etc - basically, enough that I could take some code and edit it to suite.
I was hoping that creating an app would a) help grow my current business and b) give me a new challenge to learn new code.
Anyway, I'm really stuck on what to do. I downloaded Eclipse at home, but my laptop is on it's last legs. I have been creating the app at the office, using Adobe Flash Builder 4.7. I read a few tutorials, and downloaded some sample apps to learn from (as part of some of the tutorials). However, none of them have what I want.
My App Idea
So, enough waffling on, I'll try and explain my app without giving away what I want to do.
Basically, the app will be one where users can enter an error code, and press search. The result would be a page showing the description of the error code, and then what the solution is to fix it. There is then potential to add a "buy this part from" link which will suggest suppliers to visit.
So, as an example, let's say a user got a Blue Screen error code on their PC of "ABC1234". They would enter that code into my app, and the result would say something like:
Code: ABC1234
Description: RAM Error - overheating
Fix/Solution: Replace RAM
What I Have So Far
Other than a couple of test files that I've been learning with, I don't have anything solid in terms of an app. What I do have though is an Excel file with 889 error codes and what each code means.
What I Need
So, I guess what I need is either:
some help/guidance on how to create an app that in it's simplest form is a home page with a search box, and then 889 pages in the background that return depending on the searched error code.
or, someone willing to help me develop such an app
Firstly, download Android Studio - Don't use eclipse anymore
Secondly, here is a tut on using an older version of Android Studio
Have a go, see how you end up. Let us know, if you're really needing help, ask here again
Thanks,
I'll have to try that once I get home as the IT Administrator at work has to vet everything that gets installed.

Thanks sir but do we have a highly compressed Android Studio? 800mb+ is such a big file to download.
Like minooch said, install an IDE, understand how it works and then try some tuts on Internet to learn how Android works. What you want to do isn't really hard, you'll manage quickly to do it but you will be prouder if you do all by yourself.
Some hints : Don't go coding directly, try to organize your project (data structure, classes, methods) before starting to code. On a small project, it's not as important but if you start doing things well now, you'll thank yourself in the future

Firstly, download Android Studio - Don't use eclipse anymore
Secondly, here is a tut on using an older version of Android Studio
Have a go, see how you end up. Let us know, if you're really needing help, ask here again

Morning all,
I have never created an app, but decided to look into it late last year. I began work on an app around September 2014, did a little work every weekend, and haven't really touched anything since November.
I have experience with HTML, CSS etc (I can write them). I can also have a basic understanding of other codes such as PHP, JavaScript, Java, C etc - basically, enough that I could take some code and edit it to suite.
I was hoping that creating an app would a) help grow my current business and b) give me a new challenge to learn new code.
Anyway, I'm really stuck on what to do. I downloaded Eclipse at home, but my laptop is on it's last legs. I have been creating the app at the office, using Adobe Flash Builder 4.7. I read a few tutorials, and downloaded some sample apps to learn from (as part of some of the tutorials). However, none of them have what I want.
My App Idea
So, enough waffling on, I'll try and explain my app without giving away what I want to do.
Basically, the app will be one where users can enter an error code, and press search. The result would be a page showing the description of the error code, and then what the solution is to fix it. There is then potential to add a "buy this part from" link which will suggest suppliers to visit.
So, as an example, let's say a user got a Blue Screen error code on their PC of "ABC1234". They would enter that code into my app, and the result would say something like:
Code: ABC1234
Description: RAM Error - overheating
Fix/Solution: Replace RAM
What I Have So Far
Other than a couple of test files that I've been learning with, I don't have anything solid in terms of an app. What I do have though is an Excel file with 889 error codes and what each code means.
What I Need
So, I guess what I need is either:
some help/guidance on how to create an app that in it's simplest form is a home page with a search box, and then 889 pages in the background that return depending on the searched error code.
or, someone willing to help me develop such an app

Hello.. You just cannot make a app like for such kind of work. You have to make make a website server for the same and then make a app for it. I know a technique for such kinda work.Web crawling us your answer. If you could setup a website for that then I can make a app for that easily within two days. Inbox for any further information or quote back
**********Hit thanks if I helped you***********
