Development guide for ver 2.2 specifically
<p>I own a HTC Desire running 2.2 and I have decided to have some fun with programming apps for it. Some time back I had read an brief intro about Android at developer.android.com but because I wasn't too keen back then I just had it at the back of my mind.</p>

<p>However, when I visited today, I see the tutorial upgraded to higher versions since 2.2. I guess stuff explained there won't work on 2.2. As I mentioned, I will be writing my apps for 2.2 and nothing else. So I didn't find it useful to continue reading it.</p>

<p>Where can I find development guide for 2.2 specifically?  Googling didn't help me at all. </p>

<p>Also, I am not too keen on upgrading to any new version (I don't know if Desire would support them seamlessly anyway).</p>

<p>Please help.</p>
