32bit or 64bit Android SDK on Windows 64bit OS? [closed]
You should install using the ADT Bundle (there is a 64 bit version). This is super simplified, and is new with the ADT 21 release.
Find it here: http://developer.android.com/sdk/index.html
Everything you need is included in the bundle, which makes things very easy.
Bottom line, use 64 bit, and use the ADT Bundle, and this should be hassle free and will result in a standard installation.
