问题
I went through all the steps on the android dev site, installed all the SDKs, and when I start a new android project or go to android preferences the list that's supposed to show the SDKs is empty. I have the SDK location pointed to /android-sdk-mac_x86 and it looks like every things there. Am I missing a step maybe?
回答1:
Try doing a fresh install. This should fix your problem. Sometimes eclipse will bug out and create problems.
Doing a fresh install usually solves this problem for me and people i know.
回答2:
When you install the SDK you need to open the SDK Manager and download all the version you want to work with.. by default it doesn't include any.
回答3:
I think the problem is due to the fact that you didn't install the Eclipse ADT.
The SDK is one thing (and it is not linked to Eclipse), you have then to link the SDK to Eclipse.
Quite easy and very well explained here:
http://developer.android.com/sdk/eclipse-adt.html
I hope this helps.
