programming on g tab

First of all, when I searched for doing programming on an android device, I got a kazillion results on programming an android app. I don't want that. Currently, what are the languages that I can write and compile on an android device? Is java one of these?

I've always wondered why noone has posted a static gcc build for android. gcc g++ gcj, they all should cross compile. You might have to enable swap to use them though.

Android basically runs Java. That's the simple answer.
You might find some interesting reading on Eclipse with the google plugins.
If WYSIWYG/RAD environments are more to your liking, check out the "google app inventor."

Um, guys, I said I don't care about building apps. I wanted to know if I could write and compile java on an android tablet.

Not quite java...
First, Android doesn't *quite* run Java. It runs Dalvik. That's a tweaked version of Java to help google not use the lawsuit with Sun/Oracle. There's a preprocessor you have to run over he Java bytecodes to get Dalvik code. This is why you can't simply port (or rather, build, given that there's a Linux under there) gcj and use it as is - you need the jvm->Dalvik translator.
The good news is - that runs on Android. There's a Clojure (a JVM/.net language) port for android that uses that translator to run code. While it's not up to building production code, it's fine for writing/testing code on android. I assume the JRuby port also uses it.
If all you're interested in is programming on a g tab, there's lots of options, most notably Google SL4A package (python, ruby, beanshell, sh - I think). But you can find Scheme, BrainF*ck, Pascal, Basic, etc. No Java, but I found at least three languages that run on the Dalvik VM (Clojure, JRuby, and Frink) that let you access some or all of the Android APIs. If you want to explore the Android APIs, one of these will probably work.
Finally, there's IDEDroid. That runs locally, but looks like it exports the compile and execution to their web server. It has support for lots (and lots and lots) of languages - including Java. If you just want edit/run small programs to play with the language, this might be just the ticket. I think I'm going to install it so I can play with haskell....

I wonder. Why in the world hasn't anyone developed a way to write and compile java code on android?

GNU has gcj, I'm fairly certain the same tools you use to compile a kernel would work to make an ARM/Android version.

Could you please clarify? I guess I'm seeing the potential to incorporate the gtab into my work at the lab. Let just say we're a bunch of engineers trying to act like IT programmers. Why hire an honest to god programmer when you could have your engineers lose sleep over trying to program the machines?
So, please could you stop giving me single sentence answers? If I get the gtab will I be able to use it to write, debug, compile, etc. java codes? We've been doing our own things with java and it's too late to switch to something else. I'm sure it's possible, I'm just having trouble finding the answer in search as it seems noone has ever brought this up before. Ever.
Would the following be what I'm looking for?

So, I take it that it is not possible to write, debug, and compile java code on an android tablet?

I did mis-understand you initial post on my first reply.
Now that I understand you question, I'm a bit baffled as to 'Why?'
A tablet just doesn't seem to be a very conducive platform to entering and compiling code.
I don't know about any development tools meant to run on android directly. But there are people running ubuntu on their tablets.

I don't how else I can make it clearer. I'm an engineer, not an idiot. A simple google search turned up millions of links to how to manage android projects on a pc. Why in the world would I be asking this? And I even said I google searched and it turned up nothing.

The whole point of having a tablet is its light weight and the touch screen. I'd like to be able to take it to meetings, take notes with a stylus, show colleagues basic autocad drawings, write and debug java codes for some of our projects, etc. This is not to say I want to use it as my main device. I will still be using either my laptop or my desktop for my projects, but having something like the viewsonic gtab to carry around and do these things seem cool to me.
I'm just baffled why there hasn't been an app development to run/compile java code on the android OS.

Yes, I'm a prick. I fully admit this. This attitude came from years of experience with 1337s online. When I first started getting into linux, and this was back in the days when there was no visual interface for installation and you had to type in a dozen commands for every step of the way while it asks you for the specific models of your peripherals, I searched for several days on solutions pertaining to a problem I ran into. After being fairly confident that there was no answer to it, I signed into a linux forum and asked about it. I got a couple one-liner answers that made no sense, a couple answers that assumed I was an idiot so they answered the wrong thing, and half a dozen "you're an idiot, go away" answers.
My first rule of thumb is if you could interpret a person's question at least 2 ways, then without further info assume the interpretation that doesn't include assuming the other person is an idiot. And this is for an obscure question. My original post clearly stated I was talking about debuging and compiling java on the android tablet itself. I specifically worded my question like that because I knew people were going to assume I was talking about the thing you assumed.
This 1337 attitude online is getting old.

Thanks. I guess this is what I will have to go with for now. I'm sure I'm not the only one who has thought of this before. Surely, if you could run it on a linux distro such as ubuntu, then I'm sure it's possible to do the same thing on a different OS that runs on the same processor. Why in the world hasn't anyone come up with this yet?

I'm a materials/structural engineer who's an amateur programmer. I practically live in my lab. Sure, the other engineers often look at my programming work with oohs and aahs, but I assure you they look like something put together by an idiot if you're a software engineer. Something like this is several miles above my head. Most of my work look like spaghetti code anyway.

The same could be said about autocad, and yet there is an autocad app for it, given that the capabilities are limited.

[Q] computer programs to android

Basically the company I work for has a computer program that one of our old IT guys wrote, now I am wondering if there is a easy way to just transfer the code over to an Android app so that it works on Android phones. or will it just be easier to rewrite the code? Thank you.

Depends on the Code it is written in, what it does, the scale of it and its documentation.

Thank you for that. the company I work for has actually decided just to remote into our windows servers using a RDP client on android. We have explored our other options but this seems to be the best way to move forward without redoing all our systems due to how they are all interlinked.
Thank you for your help

Looking to Develope

Hey Guys (and Gals),
I've been in the tech scene for a while, rooting and unlocking android/softmodding psps and xboxs for fun. However recently I wanted to contribute to the scene, and I'm kind of in a dilemma. I want to make a few apps, nothing crazy ambitious just learn how to. Though I'm not sure what platform to do it on. I am kind of torn about doing it on Android or doing it on the Windows marketplace. I want the simplest setup, (i have 2 windows 7 computers, and a htc rezound and toshiba thrive and tf300). I took a college course on C++ but it didn't even touch on guis or go that far in depth. So basically I am starting from scratch either way.
I like android and have a few pieces from them, but I feel as windows is just getting a start it would be a good chance to start also. Furthermore what language is best for each platform? I have heard java for android, but heard a c type program is overtaking, and html and javascript for windows. Any input is greatly appreciated

Woo! Somewhere I can be helpful.
I'd recommend researching a few game engines / frameworks. For example, check out Marmalade SDK (google madewithmarmalade), it's a cross-platform game engine that will abstract your game from the hardware it's running on.
I'd also suggest sticking with c/c++, it's probably the most versatile, and you'll be able to use it with Android, and iOS (and I believe the new Windows 8 mobile platform).
Hope that helps!

thanks, ill definitely look that up, any suggestions for tutorials on using c++ with android/windows?

App requests?

I know this is a potentially dangerous post, but I'm looking for suggestions for things to port. I make no promises that I'll be willing/able to port any suggested software.
Some ground rules before you hit 'reply'
1) Don't ask for Chrome. I won't port it. Period.
2) The source code must be available and not have any _obvious_ specific ties to non-open source code. Eg: some proprietary or closed source library which it depends on.
3) Code must be in C or C++ (I can deal with porting some assembly if needed)
4) Project must be of a _reasonable_ size for 1 person. Honestly, I do this on my own and in my spare time. Some apps can be just massively overwhelming to port. That being sad, sometimes the big ones are also easy.... so use your own judgement here.
5) Tell me why you want it ported. Whats your "use case".
6) Drivers aren't out of the question, but they generally take significantly more work.
Feel free to +1 others suggestions.
Ok.. <puts on protective gear>.. fire away!
Cheers!

Thanks for all your awesome work.
While this isn't an app, I think that the kexec kernel-mode driver idea that was tossed around earlier would be waay more useful than an individual app. Every time it was brought up somebody said "Oh, that won't be much work." And then nobody did anything :-/
So, I'm hugely grateful for the time you put in here, but I think I'd be even huger-ly grateful-er if you opened the door to other OSs.

I wish XNA could run on Windows RT. It'd be funny to see Terraria and Magicka on Windows RT...
Firefox would be nice, but without a Thumb-2 JITter, it's not worth it.

Would be nice to have InSSIDer. I use it a lot on my laptop, rather leave it at home.

I would say to take a look at monogame. It can actually build microsoft store apps including ARM support, so coercing it into functioning on the windows desktop may be possible. Otherwise it might end up being a rule 4 :/
There are hacks out there to run terraria on MonoGame instead of XNA, most of them pretty complete but sometimes have the odd graphical glitch. A full source port to MonoGame would be far more reliable, and actually very simple, but sadly its closed source (although not obfuscated).
One of the supposedly more reliable ones: http://www.terrariaonline.com/threads/wip-monogame-terraria-terraria-for-linux.72997/

Just found one. TCPMP, this player worked great during the PocketPC/Windows Mobile era. It moved from open source to a commercial different version which is closed source but I believe the link below has the source.

This would bring about a player that supports MKV playback.

I think the problem with the current torrent apps are you either have to pay to get the ability to download files in the background, or the app doesn't support it. I'd like to see a free torrent client that allows background downloading, even if it means speed has to be throttled a bit.
To the OP what is your favorite browser? If it is not Chrome(or Chromium), do you think it is possible to port that browser? At this point I'll even take Safari as I am starting to hate all the crashes that occur for me in IE.

Safari is not open source so cannot be ported.
Chrome is a rule 4 - or in other words is too much effort for 1 man to do in a reasonable time frame.
Firefox is also a rule 4, plus its a ***** to get it to compile properly under microsoft tools apparently, plus its javascript engine is raw ARMv7 JIT whereas windows RT bugs with that and would require a THUMB2 JIT. Chrome also would have javascript issues, although in chrome you can have an interpreted javascript engine I think which would just be hideously slow in comparison.
Opera - Closed source.
The list goes on unfortunately. Browsers are complex creatures. Most will come under rule 4 though.

What the hell are you doing to get all these crashes? I have yet to have IE crash on 8 or 8.1 on RT in desktop or metro.

My only suggestion would be a gui SFTP client. This is probably the one utility I am currently missing on my Surface RT (I use ssh to remote into Linux systems both for work and personal use, point #5). To clarify, I do use the psftp client in the putty suit, and that works well enough, just takes a bit more time and effort than something like winscp. I can continue to use this if an gui alternative is not feasible.
I recall someone requesting winscp at some point in the past, so I searched around this forum and I did find a couple of people that took a stab at it, but with no results, and I haven't found a clear explanation on what the hang up was. Looking at the readme winscp appears to be written in c++ at least (point #3):
To build WinSCP you need:
- Embarcadero C++ Builder XE2 Professional.
- Copy MFC source code from Borland C++ Builder 6 Professional and
build its Unicode version (see readme_mfc.txt).
- nasm from http://www.nasm.us/
- To build 64-bit version of drag&drop shell extension, you need
Windows Platform SDK:

I am unsure if the aforementioned Windows Platform SDK is available for Windows RT, or if it is even needed since Windows RT is not 64-bit.
Is nasm the problem? It looks to be an x86/x64 assembler... which of course wouldn't work on ARM... unless I just don't get what an assembler is...
Not being much of a coder I also don't know if one can import a Borland C++ project into Visual Studio, so maybe that is also a problem too.
So I guess I'm not sure on a lot of the points on the ground rules list...

Borland C++ is an alternative set of 3rd part C++ tools. Would take a bit of work to get a borland project to compile it under microsoft tools.
Nasm is an x86/x64 assembler yes. Assembly language is pretty much the lowest level of programming possible before writing in raw hex or binary. It is *HIGHLY* CPU dependent. Specifically the set of commands available in assembly is the plain text form of the exact instruction set the CPU has available which for x86 is different from ARM. The fact that nasm is required means that the project will have assembly in it, therefore an RT port will not be undertaken (one of the rules in the OP).
Sorry man, its proprietary tools and parts of it are unportable anyway. Doesnt mean another SFTP client can't be ported, just this one.

Here's my wishlist. I've poked at some of them, but I don't really have time to finish any of them.
WinPCap - Iirc, the biggest issue was that it was written targeting an older version of NDIS. The usecase would be to provide network support for BOCHS.
QEmu - There's a build of QEmu that builds on MSVC called WinQEmu, but it's dynarec recompiles to x86 only. I believe the official QEmu repo doesn't support MSVC, and I don't know if it can recompile to THUMB-2.
A good IRC client - X-Chat and mIRC run poorly under the emulator, and the few .net clients I've tried are meh. X-Chat has too many GCC-specific requirements, and mIRC isn't open source, I just want a good IRC client.
An X Server - I've been unable to find an X server that builds with MSVC, or anything short of Cygwin for that matter, but I'd love to have one.

Calibre is a good eBook manager I think this is the correct source code https://code.launchpad.net/calibre
I'm not good with this source code stuff so if its to much you dont need to make a port but if you can it would be appreciated thanks

Greetings, Somewhat tech Savvy retiree with a new device and needing a little help/info

I have a Tab S8 Ultra. I really like using DEX to emulate a computing environment. I have a small business and able to do just about everyting in need with it. However, it's not a 'true' laptop. Nevertheless, I want to cut ties with the laptop. There's one program I really need to do so. I have HGTV Home & Landscape Platimum Suite ver 3. It is, of course, windows based and my tablet is Android. Does anyone know of any available Drivers that will allow me to run it or is it even possible?

I just read an XDA contribution piece by Kyle Wiggers in January 2018 about "WINE - Compatability Layer for Windows. I'm really not sure if im on the right track here. However, this is the closest info I've found concering what I'd like to do. I'm wondering if there is any more development on this.
