What device information can be accessed in android

I working on an android app which can benefit from device information. Like make, model, API level, 开发者_高级运维resolution, size, installed apps, memory, etc.

Can you direct me to a link which might be useful to learn what all is available and how to access it?

Take a look at this

It holds various informations regarding the cellphone (or tablet). You might also need some information that can only be accessed with the proper permissions, so take a look at this other.

Both links are from android's developers site
