Can any body post tutorial for building a custom rom for G1 and Hero?

wrong area to post this... probably should take it off.

were should i put this thread then

Q&A buddy.

I wrote a few how-to's on compiling your own android build from source, i recommend starting here:
http://robblue2x.blogspot.com/2009/07/how-to-set-up-ubuntu-virtual-machine.html
it is a bit out of date now because android moves so fast, its incredibly hard to keep up to date!

Just visited this link But how do modify the existing files of android OS ?

If you have to ask how to change the files then you probably shouldn't be messing with the code for an OS. There is alot to it. You need to know how to set up linux, Git, repo, sdk, emulator, learn java,maybe some C++, edit xml files, and compile the edited code just to name a few.
read this
If you get that working then all you need is a text editor to start changing code.
Good luck!

What about modding existing roms?
Here is what I know so far...
system apps are not individualy signed
Rom must be packaged in zip having 3 root directories.
data (holds apps normaly)
META-INF (holds some kind of build files... and android manifest)
system (holds the OS and scripts and such.)
Also boot.img in the root dir.
The update.zip needs to be resigned if repackaged.
=) that is it all that I have gathered after hours of searching.
I dont want to recompile a kernel as I dont need to modify one. I would rather leave that to the more experienced DEVs. All I want is to remove/replace few apps...
My questions:
How do you sign a file... (tried the sign java thing in ubuntu and I get some king of error... could not find library and what not...)
There is a windows batch file floating around I have not tryed that.
I have some basic understanding of code language and I can flollow instructions even if I have to find my way around some stuff... but this rom building is like black magic... Everyone is doing it no one wants to explain how its done... If its too damn hard then so be it. I can modify it on the back end after installing. I just believe in clean simple installs.
What generates the META-INF directory and the files in there. Seems like there is some instructions on setting permissions for certain files and (manifest) seems like signiture keys..
Is that generated when the file is signed?
is it manualy generated?
is can those files be modified?
I know if this is answered it would be helpful in letting people optimize the builds for their own needs.
Sorry for the long post. I hope this gets explained or I dont care if I have to read, give me a bunch of homework (links).

my advice for signing files would be to read through this thread. stericson says that JF's autosigning tool will work in linux. if you still can't get it pm stericson, he is a very nice member and should be able to help you

Thanks... That worked in windows.
Im getting some FC's but I can at least work on that now...
I did remove everything from the MANIFEST before signing just in case something did not get overwriten correctly.

I don't mess with the manifest files, so try not touching them and see if that helps

Can any body describe what does these files do while building a theme and how to edit these files:
android.policy.jar
framework.jar
services.jar
build.prop
build.sapphire.prop
build.trout.prop

the prop files are configuration files and should NOT be replaced if your making a theme.
the .jar's should only be messed with if your adding stericsons lockscreen. you will have to decompile them for it to work

How to decompile the services.jar files?

Check out my theme thread. It's from when I was porting Android but most of these questions are explained in pretty good detail with links for more info. That should help you out quite a bit:

[help] how to make a update.zip???

hey does anyone know how to make a update.zip for a apk???

you need to create an update-script that basically tells the flashing app where the file of your apk goes in the live system.
zip and sign and you're done.
if your next question is "how do I write an update-script" I would suggest you download any of the roms available, extract their script and have a look at it.
its quite basic, not much more difficult than writing a batch file on DOS.
there are a couple of threads that give a few pointers as well but they are somewhere in xda, not necessarily in the nexus section.
search for update-script and you'll see.

thanks mam ill give it a try

Remove the .txt extension or use the META-INF folder in the .zip that already has the same update-script in it or finally, you can use the empty update.zip which already has all the components in it, you just need to add your .apk's and .jar's to it.
This is a basic update script that works well for themes (or at least for me it does). In your .zip have META-INF (for the update-script) folder (take one from a ROM or theme) and an app and a framework folder and it will work.

Editing 9.pngs unparsed error?

Okay, i need a little help, I try to add a 9.png to a sample app in eclipse so i can export it and have it show up corectly, however i get this error everytime i move the file into a drawable folder-
Description Resource Path Location Type
Unparsed aapt error(s)! Check the console for output. com_example_android_softkeyboard Unknown Android ADT Problem
This also makes it so i cannot export the apk, I have been reading and searching for a long time, but have no success.
I've followed the thread on how to edit 9.pngs also found on xda but i seem to have a problem not mentioned.
Any Help?
Shooot, i thought i was in a diffreent section my bad! Please move this!

How many other .9.png's do you have in that drawable folder? I found that if I had too many in one of the sample apk's that it would not compile. I finally just started a new one, and it hasn't let me down.

I only add one extra 9png file into the folder along with the already existing files in the folder (its a sample fromthe 2.1 sdk)

That error usually means that you have more than two stretching points on either the top of left side of the .9.png borders. Anything over two seperate points will seriously cause errors and won't let you compile. Fix it. and it'll compile.

Because you are making an app its different if you have never used it before check out draw9patch.bat in the SDK tools im sure google android wiki has something on it.
Best way to mod .9.png's is to just use the orig image and copy and paste your new stuff over old. I have been working with alot of .9.png images and this is easiest way to get around problems.
If you continue to have issues try compiling what you have without your mods maybe its the project itself.

[Q] Confused former Windows Phone 6.5 user/themer

Hi Guys,
I'm coming from Windows Mobile 6.5 where theming was a bit different:
When I started with 6.5 I used to think the only way to change the look of my phone interface was to flash a custom rom, but then I realized I could theme individual components (6.5 theme, Taskbar, Icons, Start Menu, ect) and it turned out to be pretty easy.
With Android I'm begining to think the opposite exists, is it basically true that in order for me to change the colors of the taskbar, or menus, taskbar icons - I have to use a custom rom?
I have been reading over these threads for the past three days and I have learned a lot, but I'm still confused...
I used to do M2D themes and change the xml and such, but when I read the Android theming guides ALL of it seems foreign to me...does't seem like I can just swap out pngs for pngs I made in Photoshop Am I making this seem more difficult than it is?
Are there individual themes for my taskbar, dialer, ect (not roms)? And if so can a former Windows Phone user explain them in comparison to installing a cab?
I know I have a ton of questions so any help at all would be appreciated
Thanks

There are MANY apps out there that will allow you to make these changes. Do some searches on the market and you'll find them. Do some research into rooting your phone (at your own risk) which will allow even more options.

You do not have to use a custom ROM to theme your phone, but it makes it a lot easier overall. AFAIK, you still have to have your phone rooted to theme more than icons.
To theme images, it really is just swapping out your images for the images already there as long as they contain the same dimensions, format (pretty much always .png), and name.
The .xml files are easiest to edit if you have decompiled the apk with a tool call apktool, because then they are in readable format.
Apktool is also really great for getting .9.png's in decompiled format with the stock guidelines intact.
You can theme various different components with an app called Metamorph or Ninjamorph, otherwise, you're going to have all your different parts together.
I've been theming android for getting close to two years now, so if you would like more help, you can PM/email (david1667jones gmail) me for more specific answers.

megaman - ain't it a trip coming from WM to android? yeah...WM seems such a simpler way. especially CHT2...that is really the best modding system ever.
been experimenting for the past 2-3 weeks and have been successful. (even have a usable CM7 theme that i may post...)
so let's hash this out. maybe teach eacho other a thing or two. if i am being too basic, let me know.
apk - like a cab. tricky thing is that (i believe) if you edit an apk, you replace the entire apk. unlike a cab where you can replace 1 single file. there are theme programs (metamorph - haven't used it, ADW and others that allow replacement with a single file...but they take a little work. nothing easy like cabs for WM.)
to begin you need 7zip (or winrar i hear works.) this will allow you to open apks, replace files and restore them in seconds:
http://www.7-zip.org/
i assume your rom is rooted (i really don't understand the term, but it allows freedom to mod your phone. i am using an HD2 - WM phone - running nand android so by default my phone is rooted.)
let's explore - take any apk and open it with 7zip. you will see 3 files (this is off of memory as i am at work right now.) open them and look around. ((want to find your installed apks and back them up? search market for Astro. (settings> backup and save your apks to your sd card)))
under res you will see drawable folders - this is the jackpot. in there you will see your images. there is a lot of redundancy in apks. the trick is finding the right image. try changing some, etc. this is the most basic of theming.
before moving on to xmls, etc (which there are quite good guides for this) just try the above. when you replace the files move up the folder hierarchy and it will ask you something about saving/restoring - cilck yes. the apk is now modded.
install the apk and see the changes.
however, if you are editing the core apks - system and framework-res, we will need to talk about how to do that (i use clockworkmod flashing...easy to do.)
let me know if this helps.

Thank you guys so much for your knowledge!
I do have my phone rooted and I have bootloader installed
The one reason I thought that I had to download a "ROM" is because I keep reading about having to be deodexed in order to modify...and I was underthe impression that most custom roms provide this deodexing?
on to APK's...I do have 7Zip and I have opened some up and found where the graphics are...now I am actually extracting the apk so I can manually go through each folder and see whats there including graphics...there does seem to be another way of opening the APK with 7Zip and not actually extracting it, but I don't thing I can actually see the image previews this way. >>>so I extract, change my desired images, re-zip and change the file extention back to .apk - BUT then I read about signing APK's? ...and signing zips?
After some researching I found a thread in which someone posted something like they make a copy of there current ROM "theme?" and then copy it in zip form on to their PC where they goe through all of the desired APKs and then Zip it back together and install it from the screen that you get to after holding the power button and home (recovery screen maybe?) <<< Anyway is this possible? This seem most like what we did in windows phone...but again I think where I'm getting caught up is the signing aspect...I've seen auto signers, but I feel like the ones I've seen were only for XP and I have Windows 7.
Woo... ok wrote a lot there - if you have anytime to elaborate on anything, I'd be happy to hear.
...and jsmccabe - that HD2 is one awesome device...I remember everybody asking if Windows 7 would everbe available and now you guys are dual booting with WP7 and Android - AWESOME!!! (if I didnt have Verizon

- not sure what deodexed means. is your rom cm7? if so, tmobile themes is an "easy" way to make a theme.
- are you theming to share or for yourself? if the latter just replace the the files in your rom and flashe the rom. if the former, what type of rom?

- you can extract to make life easier. but when you are ready to make the changes just drag the new icons into the original apk. it will update it for you and you can install it and done.

CWM themes are pretty easy to do. i started with this, the problem is it replaces the entire apk to replace 1 image. which if you are modifying systemui or frameworks, may overwrite other things (colors that you didn't want to.) easiest thing to do....find an already established CWM theme and keeping the same structure, replace the images and flash via CWM.
let me know if you want more details...cheers and good luck!

compressing file on Windows

J.Michael said:
I don't think that's too big to post without compressing -- just attach the file.
Are you using Windows on your PC?
Did you copy "recovery.log" to your PC?
Did you look at "recovery.log" in a text editor?

When I asked those questions, I had no interest in seeing the log file. I wanted to pursue what I thought were strange problems doing something that should have been simple.
Spiralling out from the middle, I didn't understand the "file not found, or no read permission". I wanted to pin down whether Windows Explorer was manipulating a file on your phone, which might (although I don't know why) explain the problem.
I asked about you looking at the file just to get confirmation that you had succeeded in copying the file to your PC.
Maybe it has something to do with where you put the file. The context menu option to compress a file is convenient, but gives me no control. (I think it was quite nice in Windows XP; not so nice in Windows 8 or 10.)
The way I remember it, you select the files, but you can't tell it where to put the ZIP file. Maybe the way you copied the file from phone to PC had enough privilege to put it where you put it, but later, in Windows Explorer, you did not have enough privilege to put the ZIP file in the same directory. (And maybe the error message is less than accurate, and it is not "Read" privilege that is lacking.)
If you want to pursue the ability to make ZIP files:
move the file somewhere else and try again. I don't know exactly where you put it the first time, so I can't suggest a clearly different and safer choice. I would think that the personal directory Windows wished on you (maybe C:\Users\Aquiladroid) would be safe.
Look into 7zip: There's a free version. It has both Windows GUI and command line "apps".

{Mod edit: Quoted post has been deleted}
This thread was a sidebar to another thread, to avoid cluttering the other thread with material I thought was off-topic.
You do not describe your 7 GB file, or what you consider "not very effective". Not all files compress "well" (to me, large reduction in size). I expect 7zip has options to control the trade-off between time spent compressing, and amount of compression achieved.
You should start a new thread, asking for advice. There are a lot of people who will notice a new thread, but who do not "watch" this thread.
