Trouble installing Android 4.2 APIs

Question

I updated ADT through Eclipse today to version 21. Now when I open the SDK Manager I would expect there to be a folder like "Android 4.2 (API 17)", which would contain the SDK Platform and APIs, documentation, etc. However, instead I just get a folder called "API 17", and the only thing in it is "Google APIs", which I can't even install because

Installing this package also requires installing: - Missing SDK Platform Android, API 17

What do I do here? Thanks

Answer 1

I figured this out myself after some poking around. I went into the settings for the SDK Manager, cleared the cache, and told it to use HTTPS, then refreshed the listing and it all appeared normally.

Answer 2

Eclipse > Window > Android SDK Manager > Packages > Reload

It then properly updated the UI to let me choose updated software.

Why do I need to click "Reload" manually ?! I expect that to happen automatically when I open the SDK Manager.

Answer 3

By this step~

1) Eclipse > Window > Android SDK Manager > Packages > Reload

2) then install the sdk
