Learning...

Where should i start first to learn how to code for android, make roms and compile the android tree?

or just a good place to start?

From what starting point?
Building android to make custom builds involves knowing lots of things; java, c, linux, gcc build system, android platform, etc, etc.
To make apps you just need to know java and the android platform.

Code for Home screen Pull up Menu
I have a similar request but was unsure if I should start a new thread, If this needs to be moved my apologies (I also searched through Q&A forums as well and came up empty ). Where or how could I get the source code for the Home Screen pull up menu? I checked out the Google Source Code but it requires Linux or Mac OS and I run Windows Vista.

i don't think you can compile the source code in windows

Yeah, I'm considering running Linux on my laptop alongside Vista, as I have hit dead-ends on a couple projects simply because you need Linux for different things . All I really need is a place that I could find the source; I had an idea that I proposed to mohsinkhan47 for his Vista theme and he asked me to find the code for the pullup menu. It would be much appreciated if anyone could guide me in the right direction.

i know where you can get the entire source code. grab it from here

Thanks for the link, that was the site that I went too before but says I need either Linux or Mac OS. Still scouring the android sites but coming up with nothing .

Yeah I do not think there is a way to compile the source in windows. I guess like stericson once said "you're going to have to get your hands dirty and use linux" (it was something like that.

Guess I gotta break my cherry sometime, thanks all for the advice.

[Q] Installing Linux on Android

I have installed Ubuntu on my android phone by following the nexusonehacks.net guide. All is working well. The reason I am creating this thread is because in nexusonehacks.net guide he mentions that he got his ubuntu.img from some guys at the xda forums.
I am wanting to get an ARM img of mint linux (LXDE version) and while I have spent countless hours trying to figure out how to install mint linux with an ARM emulator it appears to be above my linux knowledge.
I know that mint linux is based on ubuntu and should have the latest linux kernel and therefor has ARM support built in already, so that is not a problem, no need to compile a kernel with support for ARM.
Basically I am just looking for someone who is running an ARM emulator or has an ARM based laptop to install mint linux (LXDE version) and do a disk dump of the HDD into an image file I can then use to replace the ubuntu.img file I am currently using on my phone.
If this would be a simple task for someone to do and upload the image, I would be most appreciative.
It would be best if I could have the dev who provided the original ubuntu.img file to nexusonehacks.net do the dd of mint linux as I am sure he knows all of the details of how to do a proper dd for use on an android phone. If anyone can point me in the direction of that particular dev, that would be great, thanks!

Buddy of mine was working on gentoo for his N900, which is an ARM proc. Ubuntu has an emulator for that, he said that it seems only ubuntu does, but you run a virtual machine with an ARM emulator. Thing is that I'm not sure if a standard ARM emulator would work too well, the chip on the N1 has some extra stuff on it apparently

It sounds to me complicated because Linux Mint is not distributed for ARM...
Take Debian
I know I did not helped, I just gived my advice on how to get Linux on Android phones: get debian which is available for tons of architectures, including ARM, natively.

Well, it doesn't really work that way. If the distribution doesn't have their packages built for ARM then it's not going to work. Yes the kernel supports ARM but it still has to be built specifically for the processor it's going to run on. That goes for most other software packages too.
Getting debian and LXDE running on the N1 is pretty easy to do. There is a guide buried a few pages down in this forum. Also, I'm hoping to release a script to help automate much of the install soon.

Yes you can you can either dual boot windows and linux or run it in a virtual machine or you can use a special installer that essentially allows you to install linux like any other windows application and uninstall it when you want to get rid of it.
I assume you want to get into android development maybe compile android from source. I'd recommend ubuntu and until the kinks are worked out I'd go with ubuntu 11.10 which you can get here:
http://releases.ubuntu.com/11.10/
Information on dual booting windows and linux:
http://www.linuxbsdos.com/2011/10/27/dual-boot-ubuntu-11-10-windows-7-on-a-pc-with-2-hard-drives/2/
https://help.ubuntu.com/community/WindowsDualBoot
Running linux in a virtual machine:
https://www.virtualbox.org
Install linux using special installer (wubi):
http://releases.ubuntu.com/11.10/wubi.exe
Hope this helps you if you need any help feel free to ask or if you want some guides on developing android on linux (compiling from source, kernels, etc.) I can help with that to

Always glad to help let me know like I said if you want some guides on compiling linux on android and suff like that ... oh what the heck here are some guides:
Official Google guide to building Android from source on Linux
Official Google guide to building Android Kernel from source on Linux
Build Cyanogenmod from Source
How to use Github for Android Development
Basic commands for Linux and Android

Moved to Off-topic.

The easiest way to install Ubuntu is to use Wubi. It lets you install Ubuntu like a regular application in Windows.
- Download Wubi
- Choose Ubuntu in the list
- Click install
- It'll download and install Ubuntu for you
- Reboot and choose Ubuntu at boot
- You're done.
If you want to remove Ubuntu from your computer, you simply boot into Windows and uninstall it like a regular application If you decide to permanently keep it i recommend you install it by itself on a separate partition. That way it'll run better. But if you just plan to try it and you're not planning on running some heavy stuff (games etc.), then Wubi will do it just fine.

Port Ubuntu Touch

Hi guys,
If you're, like me, greatly excited to get Ubuntu Touch onto your phone, and/or tablet, here is a guide to port it!
It helps you get started on a port:
https://wiki.ubuntu.com/Touch/Porting
Also:
This is not a thread for eta:s for your device port. Nor is it a thread to ask for a port. Both of which you'll have to go to each device's own forum.
This is a thread for discuss ports, get help on them and to share experiences.
For Ubuntu Touch specific questions, see other threads.
FAQ:
Can you port device X?; Ask in your device X's forum. Or even better, try it yourself! It's not that hard, actually. See link above.
Does Ubuntu Touch run Android Apps?; No.
Will it?; Maybe. If anyone cares to actually make it work.
Do I need to have X; run Y; or do Z?; Check the Port guide! https://wiki.ubuntu.com/Touch/Porting

Everyone with a nexus needs to install Ubuntu and then show everyone they know how in it's current state it is unusable except as a test device for apps.

Well, it is a dev release for developers and Ubuntu enthusiasts, so they probably already run Ubuntu. And if not, it's a 20 min install.
And porting it is still a large project by itself, so it'll go nicely hand in hand until the stable release of Touch, I think.

Just been reading through the process and if seems relatively straightforward to port so I can't wait to see what comes out of this

Because some of the Android components are reused. Read here: https://wiki.ubuntu.com/Touch/Porting#General

Ubuntu is a distro. Linux is an OS. Android is kind of a distro too.
Please correct me if I'm wrong.

Actually pending when canonical gets to compile drivers for particular phones which incidentally is probably going to be for only their oem devices, they use the cm base.
Essentially just the drivers and hal layer.
Its not based on CM. It takes advantage of CM base. Its direct ubuntu.
And from what iv seen you can forget about lag. The alpha is awesome compared with android alphas

yes i have read this but my english isnt perfect so i maybe didnt understant something.so because ubuntu and android are based in Linux kernel,they taking some stuff "ready" for more easyness.something like that?

Phones need drivers like your PC does and a kernel which acts as interaface between the hardware and the operating system.
Everyphone uses its own vendor supplied kernel with some modifaction and their own graphics driver. So they use the low-level stuff that already exists for Ubuntu.
You can't just make one "OS" for a smartphone that just works on all devices it has to be ported to the specific hardware (kernel and driver).

thats what i mean.so they took the allready existing stuff from cm10.1 because it will work with ubuntu (or with some small changes) because both OS are based on Linux kernel.i understand right?

Ubuntu is a distro or distribution which is a OS Linux isn't a OS it's a kernel (the underlying framework kinda like the glue)

Wikipedia says Linux is an unix like OS, but the main component is the Linux Kernel. Android only uses the Linux Kernel and not so much the GNU system tools which make it unix like, that is why people generally don't refer to android as a Linux distro.

But saying it like that makes it sound like u can use this as a Mac OS or Windows replacement which I think is what he was asking

You didn't say android was a Linux distro but he did, I was just adding to the conversation.
I think I may understand what you're thinking though. Mac and Windows are not open source and you cant build your own version, so they are not as comparable in that sense, they are binary distributions. But you can build your own Linux configured the way you want outside of any distro, a distro is just a packaged version of Linux with additional packages and configurations.

Had angie tried to pull the source code? It's ridiculously slow on my end. About 15gb at 9 to 152kbs... I guess every dev in the world is trying to pull it...Lol...too bad there's no way to speed it up

Actually, Linux is a clone of the UNIX kernel. Ubuntu is an operating system (or Linux distribution) with a Linux kernel. Android could be considered a Linux distribution as well, even though it's mostly Java stacks on top of a Linux kernel.

[QPAIR/LOA] - LinuxonAndroid GPad support

This will be used to detail how to get LinuxonAndroid running on the GPad and the process of QPair support to bring new and interesting features to the project as a whole.
Step 1 - Install Linux on the tablet
We shall start by using the standard Complete Linux Installer to install and run Linux with the GUI pumped over VNC (Frame buffer method coming soon!), this method works on most devices and is the most universal but as the project develops in the coming weeks a better method for the GPad will be developed.
Anyway on with installing!
Root
First things first you will need to root your tablet, currently my tablet is running Stock V50020d with root.
The below will most likely work on other ROMs as long as you have root it should work!
(A custom ROM may be developed for further features.. watch this space)
Download
Now we have root you will need to download the below:
Complete Linux Installer
Terminal Emulator
VNC View (I recommend PocketCloud)
Finally download A Linux .img file from our source forge site HERE, I recommend and will be using Ubuntu 13.10 Small ext4. Once downloaded extract the .zip file and copy the .img to your devices memory (internal memory or sdcard).

Let me understand, you want to port QPair to linux that will run on the G pad?
Disclaimer: I'm also in the challange but the idea of running linux on the tablet is really interesting.

I guess @zacthespack wants to use linuxonandroid on tab and sync stuff with a third party such as keyboard, etc using QPair.
Another Disclaimer here Good luck to everyone!

Bingo!
With linuxonandroid running on the tablet we could then use QPair to allow the user to have a phone (or another tablet..?) as the mouse/keyboard for Linux

posted first steps in OP to start getting LoA running on the tablet.
Everything is running very well, I shall finish the guide shortly to get LoA running but really the app install guide will work perfectly.
Next step I will be releasing a special Ubuntu 14.10 image which will be the supported image for QPair features and other changes for the GPad.

it say I need a loopable kernel which I didn't find for stock LG rom...

Stock LG kernel does have loop support so you should have no issue here, if you are having another issue getting linux to start let me know, shall be updated the OP in the next few days

Howdy, cool project. Couple of questions. I'm looking for a reason to install Linux on my tablet, but also understand that I can remotely view my home system with vnc. So what would be the benefit?
Is there more control using Linux to Linux?
Does this mean I could open into my home system, make changes to my kernel, compile, and upload to a server from my tablet?? Late night insomnia while in the mountains would be awesome. I would have to tether my tablet to my phone for WiFi, and run through Linux? This sounds pretty awesome.
Tell me the reasons it won't work.

Pretty awesome OP. Thanks!
