Starting out with this cool website I found: http://www.codecademy.com/#!/exercises/0
Also found this too: http://developer.android.com/training/basics/firstapp/index.html

+1 on learning java, then maybe some android SDKs, along with Eclipse software. You learn all this, your well on your way. Java will definitely take the longest to learn.

I'm a freakn idiot!!! I didn't have Java Runtime Environment installed hahaa. Got it working let's see how this goes.
If anyone has any helpful tips, or sites, or teaching.. ANYTHING feel free to post here!!!! :good:

You can go to googles Dev site and watch the countless tutorials on android development. Also YouTube has toms of mini series covering all aspects of a android development if you are a visual learner I would highly recommend watching these series. Try to find the newest set possible. ICS or newer as the api has changed drastically and so has the adtt plugin for eclipse. Also you can find the eBook beginning android development in PDF form its pretty good and is also based on ICS and newer. Between all that you should be able to pick it up.

Video how to?

I am sorry if this was posted before, but I was looking at some of the guides for learning how to make themes. I have never done anything like this before or done any of this type of programming, but would like to try and learn how to.
But I am a person that learns better with watching what must be done then actually reading it lol. Is it possible for someone who does themes for the epic can possibly post or make videos on how to actually start learning how to make themes from the stock files? Like setting up the different programs needed and then maybe doing a sample of how to actually make a theme from the stock.
I hope I am not offending anyone for asking this, but I find this site very fascinating but like I said I am very new to this type of programming or working with android phones.
But I will understand if this is not possible to do since so many people have different ways of working and might not be able to show there work. But any possible help would be greatly appreciated.
Thank you all for your time and patience.
youtube has given me knowledge a time or two.
There are a bunch of how to's all over these forums. Some have videos. feel free to ask questions and myself and others will help

Ok first of I know of many questions lol....Even tho froyo is out now, do we the eclipse plugin for adb? I follow the written tutorial to install sdk and the apk manager app.
But I did not install the eclipse adt plugin that the guide talked about, is it necessary even tho we are on froyo currently?
Also what would be a very good starting point for a newbie? Should I focus on a specific field of the android devices or is themeing very different from the other aspects of modding the epic phones?
I have yet to use eclipse on any theme I been apart of. I use apkmanager to de compile and re compile .apks. I use notepad ++ to edit xml files. Xml files can only be edited when the apk had been de compiled. I use gimp for image editing. You can use any photo editing program you like. I use 7zip to brite and put the images in the apk. Baksmali and smali for editing .dex files.
I suggest reading the how to's as they explain everything in detail.

I learned everything on my own. I didn't have anyone to teach me. I taught thomasskull666 and where working on some good projects. Me and dreamsforgotten are always bouncing ideas off of each other. If you see my eclair build I was the imply theme with the reboot options that I will port over to froyo once we get an official build. I also have two other things I figured out for froyo that you can see in my froyo build. I labeled all the silent options correctly to vibrate and I removed the sprint branding. Its hard to believe I was like you when I got my epic. I didn't know ****.

I'm 26. Its not hard to learn the basics. Xml for the most part is well writtin so making those changes are somewhat easy. Smali is a ***** to edit and that I'm still learning. For the most part a theme is 95% images.

How to Develop Roms

I'm sure this has been asked this a million times but i was wondering if anyone could point me in the right direction. I wanted to start developing my own roms and was wondering where I should start. I have no real knowledge of developing so i would need directions for a beginner. It doesn't need to be detailed but maybe point me to some books or something equivalent that would help me out. Thanks

Here's a good start:
http://forum.xda-developers.com/showthread.php?t=1798056
a) get apktool and a good text editor with a good set of features. Find a tutorial on how to do some modification to a system apk. learn.
b) Learn some basic linux commands, helps if you install a linux OS here.
c) learn xml or how to modify it.
d) get the arm toolchain if you want to do kernel stuff.

No problem...if you need links to anything im probably your guy, I subscribe to all threads that I feel are important (content wise)
For example, this thread shows how to odex APKs (apps). Same method can be applied for odexing frameworks files
I love being self sufficient to my phone, but it's hard. I barely know anything so far.

You have to know how to decompile, make changes, then recompile. Not only that, extensive knowledge of framework would help. Then test your work, May or may not be compatible or even work at all.

No problem, there's a lot to it if your not familiar with compiling, framework, java code, etc... I started to learn java code and stopped. That's only breaking the surface of Android OS.

Haha I see, I thought it was as simple as swapping apk's I really don't have all the time to learn all that stuff maybe on some of my time free I'll look into little by little

No, I think lockscreens are part the framework. There are lock screen apps you can download, but most are battery hogs, and probably not what your wanting. I didn't have the time either. Java is kinda confusing to learn also, much less the rest of it.

Anyone want to help me get more in to this ROM hobby thing?

I have learned all I can by reading. I need to play on a computer. DL some programs and dive in. Building my own ROM is a long way off, or assisting build one, is the direction im heading.
#1 don't assume I know anything
#2 im getting a laptop. I have kids and the computer is downstairs. Every time I try and get down there, im called back up.
#3 there are so many programs I don't know where to start. I have started on my main computer. And now I have so many things i don't know where to start. Eclipse, ADB, 7 zip, kitchen, cygwin, Java .. And i don't even remember what else.
So i think I'd like to mess with one program at a time and learn one aspect at a time. Don't advise, "download this or that" . Pick the program you recommend.
So I would like to download a stock ROM and start deleting crap. Start there. Im more in the mindset of smoothest and fast and better battery. As opposed to. Bells and whistles that seem cool, but i never end up using.
Please advise THANK YOU
Start with laptop. Id like to get a laptop that is mostly for this. I'm sure I'll check email and web, but that is it. Id like to stay as cheap as possible. I've got a pretty good Windows 7 64 bit already for my pictures and all heavy duty tasks.
So staying with 7. Will the "core 2 Duo" cut the mustard? Or do i need to get a i3 or i5.
6 g RAM ok?
Seems like i can go Duo for $200 and the i3 will be $325. Im cheap, but i hate slow too! Lol
Bells and whistles not necessary! Lol

I would stick with an i3 or higher just for some extra speed but a duo will do the job the rig i have when i have time for theming is a i5 with 16 gb ram and 4tb hard drives granted i do grafic work on it you just don't want a box that will start boggling down on you.

I have been thinking about dipping into the rom world myself as of late my taste is a clean stock rom with mild theming to make it look nicer than stock. But let me know if you need any help I'm thinking it may be time for a new hobby :beer:

small man..... once you get the hang its easy..... I like to get the big apks done first like framework-res.apk and SystemUI.apk.... then go from there..... secPhone.apk and secContacts.apk are the most time consuming. ... the hex colors of my rom are 00ff00 and a100ff.... start there and build off them...
I like to test before I release stuff that is why it takes me a while to get stuff out... but as you see it works most of the time. . Lol.....

The only guides I used were for rooting and smali edits. I originally started with a mod that Tommy Tomatoe told me I could do where I changed the font to roboto. I only used gimp and 7zip for that. That was on the OG Evo.
