About AOSP Downloading & Building Few Queries

Question

I have Lubuntu 12.10 on my machine. All necessary software's are installed for compiling AOSP. I have android mobile with ver. 2.3 I did not found any ROM ver. 4.0 for it so decided to compile it my self. I am following this guide.

The last commands i ran are:

$ repo init -u https://android.googlesource.com/platform/manifest -b android-4.0.4_r2.1
$ repo sync

Now's it's more than 1 day still it's only synchronizing. Download speed is around 50 kbps. So my Question No.1 :is for compiling to AOSP android-4.0.4_r2.1 is there any other's way that i can skip unnecessary files and download only 4.0 necessary files?

Question No.2 : I found one more link that is for only building kernels here. So if i follow this guide will it be same as repo sync that i ran cause i have specified -b android-4.0.4_r2.1 What will be faster way to download only for AOSP 4.0 and any specific guide to build it?

Answer 1

You should have read the warning on AOSP download page, if your download speed is about 50kb/s, it might take a very long time (~ a few days?) to download about 10GB of different files required to build AOSP.

Also, if you don't have a Google Nexus device, most probably the image you build won't work with your device. It takes a lot of tinkering to add the support for the very specific hardware you have in your phone.

Of course, nobody can forbid you downloading sources and building the image, but I would strongly advise against it, because in your case basically it's pointless waste of time.
