Yes yes it's here: http://developer.android.com/sdk/index.html
But I forgot to mention I'm not using Firefox, or IE, or Safari, or even (shocked gasp) Chrome.
I'm using KDE rekonq, which, although technically a WebKit browser, does not inspire that over-developed site to list anything under "Choose the SDK package for your OS from the table below."
That's right. Where you see the clicker for your least-favorite OS in that "table", I see absolutely nothing. The website does not recognize my rekonq, and does not pop in the link for the Linux version. Worse, the website does not simply barf out every version, responding to the edge-case where it cannot detect any of them.
So, while I download http://dl.google.com/android/archives/android-sdk-linux_x86-1.6_r1.tgz expecting to then tell it to upgrade itself, would anyone like to try to answer the meta-question, here; how I was expected to download the LATEST version despite using an inferior browser?
(And we will next discuss the ethics & accessibility of a CAPTCHA system that shells to YouTube...)
