How can I limit the size of the Android source I need to download with "repo sync"?

Question

^{I'm planning to leave for a country with a poor Internet connection, where I hope to do some software development.}

I have been using repo sync to sync the Android source (and the CyanogenMod source on my AWS server). But they are so large (> 30 GB) that I won't get them before I leave my country.

Is there any way I can exclude code from the tree? I only need the Nexus 7 (wifi) (grouper) device. Can I exclude any projects? If so, how?

_{I'm using Ubuntu 12.04 and repo.}

As an anti-theft measure, I need to enable creation of a Wi-Fi hot spot and get the tablets to disable themselves if not connected to other tablets via Wi-Fi for 48 hours.)}

Answer 1

This might be too late. But:

• You could pass --depth=1 to repo init to get a shallow clone.
• And you could use repo sync -c to checkout only the current branch.

Answer 2

While repo sync is invoked, though a specific branch is selected, code from all branches are downloaded. In order to limit download size, you can manually download the code from github website. Like this, you can download code from the branch you want.
