OK, I have figured out how to execute programs using the "make your own" in anycut.
However, can someone explain to me how to run a command line? Such as... "SU"?
If we can get it to load up SU, then it would be simple to execute the tether start/stop commands.
This is the only info I could find regarding intents....
http://code.google.com/android/reference/android/content/Intent.html
If you want to send commands to the console from a Java application, you need to use runtime exec. If you just want to make a toggle app, you might want to check with jasoncheng, as he seems to be trying something similar. The documentation on runtime is here. Example code here.
Thanks!!! That is what I was looking for but I guess after being up for 30 hours, my brain is coming to a crawl...
I have a few questions for the devs here. Please forgive any assumptions that may be incorrect. I've tried to do as much research as I can online but I think I need a more experienced Android dev to help me solidify my direction. Thank you in advance for your time.
That being said, I have some experience with a device known as the GP2X. It uses ARM architecture and, in the past, I have been able to cross compile for it. Notably the Stella VCS 2600 emulator. I do have some open source experience, but I've never had any formal training in programming. Seeing that Android uses the DVM to sandbox program code, I'm still a little iffy on what I can and can't get away with programatically.
First off, I've read that the Android Chrome Lite browser allows plugins/extensions through the NPAPI. I'm assuming this is the stock web browser. It's not clear to me at the moment what the default browser is or how it works. It appears that Gnash has a C++ NPAPI plugin that may need to be cross compiled and I'm hoping to get away with as little Java coding as possible.
My main questions are:
1. Does the stock browser allow NPAPI plugins?
2. If question 1 is true, does the plugin have to be compiled in ARM architecture? Are there any caveats to this?
3. From what I've been able to gather, Chrome Lite looks in the following location for Plugins:
Code:
/data/data/com.android.browser/app_plugins
Is this correct?
4. If a plugin is dropped in the correct folder, and assuming that the mime types are associated, will the Android browser recognize/utilize it? In which case, I'm sure there would be an API call that would cause it to rescan like Firefox or Opera would.
5. If cross compilation is necessary, is it better to use OpenGL, AGG, or Cairo as far as wide Android compatibility? Again, I don't know what's native or widely available in Android. I guess I'm looking for Best Practices.
I just wanted some feedback from someone knowledgeable before I go through the trouble of setting up a toolchain to handle this. Seeing that the community has been looking for a Flash player, I wanted to see if Gnash had any practical value on Android.
Thank you in advance for your time and again, please pardon my ignorance. I have holes in my knowledge and I want to get a little closer to understanding this particular subject before investing my time in development.

Hi there, this is my first post on xda so forgive me if this is put in the wrong forum.
I am new to android and wish to play around with the emulator.
What I want to do is to create my own piece of virtual hardware that can collect OpenGL commands and produce OpenGL graphics.
I have been told that in order to do this I will need to write a linux kernal driver to enable communication with the hardware. Additionally, I will need to write an Android user space library to call the kernal driver.
To start with I plan on making a very simple piece of hardware that only does, say 1 or 2, commands.
Has anyone here done something like this? If so, do you have any tips or possible links to extra information?
Any feedback would be appreciated.
Regards
Has anyone done this?

Im surprised this is left unanswered.
Yes, you can do this. There are several ways to do so, but I will explain 2 good options for you.
One: Use AndroidSDK. It's configured for android and simple to set up.
Two: Use virtualbox. If you have the android ISO, you can install it as a bootable image in this software. This gives more functionality than AndroidSDK, but it is not as simplistic. There are settings you will need to adjust to get it running. For a working Android ISO with limited functionality, you can download this: http://www.android-x86.org/download
I've read in a few threads which required the use of terminal/fast boot.
What exactly is this? Can anybody point me to a guide/tutorial on how to use it?
Thanks in advance!
P.S. - I am a newbie in playing around with the Android system.

Terminal basically allows you to run certain commands directly on your device rather than having to be coupled to your pc.
Android Terminal Emulator
Description
This application lets you access your Android's built-in Linux command line shell. It emulates a Digital Equipment Corporation VT-100 terminal. You can use this application to run utility programs on your device.
What is this app good for?
This application lets you run Linux command line utilities on your Android phone. It is mostly useful for computer programmers. It might also be useful for people who want to explore the Linux internals of their Android phone.

Hey all-
I'm very interested in learning Linux in order to not only do cool stuff at home with my own computer, but also to perhaps be of service in developing ROMs and give back to the devs who've helped breathe life into my ol' OG Evo for nigh-on two years now. If I ever got to the point of doing some 'grunt work' and helping out on a project, that'd be awesome for me.
Here's where I'm currently at with Linux: I've followed instructions to dual-boot Ubuntu on my Windows 7 laptop (yay!!!!), but other than installing Chrome and using all my Google services (Gmail/Docs/etc.) through that, I'm not really sure what else to do in order to become fluent with Linux. It's kind of like reading a book on how to build a car, but not knowing one end of a wrench from another.
Here's where I'm at with Android: I can follow instructions to root my phone, flash ROMs, install the Car-O-Dope tweaks on GB ROMs using System Tuner and ROM Toolbox, and most basic things that include using Smelkus' recovery (flashing, wiping, nandroid/restoring, etc). I'd say I know more than the average Android user, but certainly not as much as the experts here.
I've looked on a variety of forums both here and on Ubuntu's site, but I'm not really sure how people got their start using Linux and how they progressed from there in terms of fluency with Linux, applying that to Android developing, and also generally using it as a 'one-stop shop' for home use. I've read about people being able to build HTPCs on the cheap, using a computer as a file server/web site host (my wife's a graphic designer, but hates technology, natch)/media streamer/home security server, but as soon as the instructions get to "Ok, now open up your command line and follow these 28 steps......", I get a bit gun-shy.
If anyone's got any helpful tips on how they got started, any good beginner's guides (project-oriented would be great, just as reading a book on speaking a foreign language is no substitute for conversing with a native/fluent speaker), and how they grew in fluency or just any general advice, it'd be greatly appreciated. I'm putting this here and spreading it around in the hopes that some of the WAY talented XDA devs and members I've read so much from will toss a bone in my direction.
Thanks for reading and for any help!
Get very familiar with Terminal. For Android dev or otherwise, it is essential. Reading man-pages is also good to learn new commands better. In Terminal, just type "man man" minus quotations. That will get you going.

You should definitely make an effort to become comfortable with the Linux command line environment (also known as Shell, the most common Shell currently is BASH).
Try giving yourself some useful activities to do, such as: setting up a home file server with Samba, setting up a media streaming server (DLNA - Plex Media Server is a great program for this), just little things like that.
Before you know it you'll be a pro

So, is Bash something I download/install, or should it be already 'packaged' in with Ubuntu?
go to the development forum on ubuntuforums.org and find out how to upgrade to ubuntu 13.04. As that version is currently in development you should get a chance to learn a few things. That's how I learned modern linux distros. Also setting up and playing around with Ubuntu server edition might be helpful.
For app development Google some Java tutorials. Once you get the beginners stuff out of the way you should be ready to learn android development with your new Java skills.

just using Ubuntu for your day to day tasks should also help. When the other Guy was talking about bash he was talking about the terminal in Ubuntu. its a command line that lets you enter various commands. Google 'Ubuntu terminal' for more info

No Bash is something that is already packaged with Ubuntu, it is one of the most essential elements of Ubuntu (and Linux in general) because it gives you a means of interfacing with everything else. If you have a type of Linux with no graphical interface, then the shell is your only means of interfacing with the operating system at all.
So in short, yes Bash is packaged with Ubuntu and every other kind of Linux out there (if it's not, a different shell will be packed with it, but Bash is the most common one).
Maybe something for later but I have seen a number of different Dev threads about getting started with AndroidDev, I know that I have seen at least about 10, all from different perspectives/starting points. One that I could find easily was the following:
http://forum.xda-developers.com/showthread.php?t=1778984
Check it out. Basically, says ... Linux (fundamentals), CLI (command line interface or shell, fluent), Java (fundamental), XML (medium), SDK (medium) and Time - to start with at least. Hope that is useful.
