Building your own ROM

[rukin5197]

Maybe someone can help me understand... We have sources so why decompile apks? Why not just build them like you want to start with?

I'm sure it's much easier for people to open up a terminal and type in a short command rather than learn git and have to build apks over git. It's sure easier for us, but easier for them at the same time.

Well personally, I hate looking through smali files that give you few clues as to what the function calls are or how they interact. Too much of a guessing game for me.

With source code, there's no guessing game, and usually comments to help you understand what is happening and why.

Trying to set everything up and I get this.

You have to get sun java6 from a different source, I can't remember if I used lucid or multiverse or both:

sudo add-apt-repository "deb http://archive.canonical.com/ lucid partner"
// or
sudo add-apt-repository "deb http://us.archive.ubuntu.com/ubuntu/ hardy multiverse"

As gannon said, its easy to type one command to get it to recompile and another to get it to compile. I began learning programming last year and so doing the de and re compiling is pretty simple since I sorta want to see the source change a couple things and build.

Also I'm on windows 7 and I have no idea what git is or where to find the source code for the apps I was modifying. Apktool seemed pretty straight forward since it takes all the files in the given folder and compiles them into an apk.

If I can't get this tool to work and xda doesnt yield anything, where exactly would I start to build apps from source... I've followed googles directions on their development pages.

Ok, I failed to sign the apks after building them, and the system didn't like it. After signing the app I modified, it installed perfectly
Now I can mod to my hearts content and not worry about those irritating .9.pngs
Its really simple using apktool actually, although I'm sure the original source is much easier to understand since it contains comment lines.

I'm still interested in the original source, where can I find that? Somewhere with git???

Using both those returned nothing, so I assume that have the right ones

Right. Why didn't I look there first :banghead:

Edit: wait, but how can I get the source code without being in Linux, since all the pulling commands are Linux?

Those commands shouldn't return anything unless there is an error. So now you run the original apt-get install commands, and you should get the proper java.

I'm trying to make a manifest converter for Leslie's ICS box so that folks can sync from the local mirror instead of having to each pull down their own data independently (at several GB per user, I'm sure). Problem is, the CM9 manifest.xml looks like this:

  <remote  name="github"
           fetch=".."
           review="review.cyanogenmod.com" />

Which corresponds to this change:

Now the problem I'm having is, how the heck does the repo script translate ".." into "http://github.com/"? I'm thinking it must be relative to the default remote for the manifests:

icsbox:~/src/test$ cd .repo/manifests
icsbox:~/src/test/.repo/manifests$ git remote -v
origin	git://github.com/CyanogenMod/android.git (fetch)
origin	git://github.com/CyanogenMod/android.git (push)
icsbox:~/src/test/.repo/manifests$

So, taking "git://github.com/CyanogenMod/android.git" and chopping off the project name and adding ".." yields "git://github.com/CyanogenMod/.." which is equivalent to "git://github.com/".

Does that make sense, or have I had too much coffee?

Regardless, can anyone point me to documentation for relative paths in repo manifests just to be sure?

Looks like it defaults to what you use when you run init:

Right. It does look that way. But if you read .repo/repo/docs/manifest-format.txt, you will note a lack of documentation on the specifics of the project fetch attribute. Are there any other docs around that explain the details better? I really don't want to go hunting through python code to find out because I am really not very literate in python (and don't care to be).

Question: I can't decompile non-deodexed apks right?

Edit: ignore this question. I was able to compile the apks.

I'm also trying to figure out how to get my build tree synced back in time (say, to N days ago). But I'm enough of a git noob that I can't figure it out. I have a script that parses manifest.xml and runs through all the directories but I don't know the command to sync the git tree.

If you look in manifest.xml for CM9, for example, you will see the default revision is "refs/heads/ics". So let's take the first project entry, which is "build". It uses the default so...

$ cd build
$ git checkout refs/heads/ics
error: pathspec 'refs/heads/ics' did not match any file(s) known to git.
$ git show-ref | grep ics
569e20838ebaf6e7ce1fc517602a9976e67f6e1c refs/remotes/github/ics
569e20838ebaf6e7ce1fc517602a9976e67f6e1c refs/remotes/m/ics

So .. uhh .. where is "refs/heads/ics" and how do I sync to it?

I'm getting the same problem. Trying this now. Why is the regular command not working?

Just a theory, I am at a different house with slower internet...could it be because the internet hear can't handle multiple threads trying to grab from sources at the same time?

EDIT: It didn't work. Took longer to get the same error.
