Missing SDK platform Android, API 18

Question

While I am trying to Install API 18 it shows only \"Google API 18\"(nothing more). Now if I try to install these google APIs from Android SDK Manager

Answer 1

If you're using the deprecated version of sdk manager like version r24.xx, then you need to first update the platform tools from sdk installation menu, before installing anything. You may have to do this several times (as long as the update notification shows up)

Answer 2

Eclipse > Window > Android SDK Manager > Packages > Reload

This worked for me. Thanks! Now I can update to 18. I'm new here and tried to vote up Jaguar's post, but I can't.

Answer 3

Seemed kind of klukey, I had similar issues. I finally got passed the api 18 msg when I updated the sdk tools to 22 which then prompted another error that the tools were degraded on reload. I opened sdk mgr again and had a 22.3 and platform tools to rev19 and some other tool choices available. I did yet another update to them along with the API19 and API 18 and it seems like it is moving along now. I think maybe for API 18+ you must update the SDK tools to 22.3 at this point. Btw, I also got a file lock during part of the process and closing eclipse in the background and hitting retry fixed. dang.. next it is saying that the ADT must be version 22.0+..
I updated the ADT to 22.3 by using the eclipse/help/install new software (Trying update simply said it was up to date)... one unsigned content error.. Restarted ADT after update.. seems to be working from what I can tell so far.

Answer 4

clearing cache solved problem for me. (Tools >option)

Answer 5

My solution to Missing SDK platform Android, API 26 ( It should work for API 18 as well)

1. Update SDK Tools
2. Restart SDK Manager and Eclipse
3. Install SDK Platform API 26, which is now visible
4. Install the other API 26 packages

Answer 6

Another way of fixing it:

0) install other packages WITHOUT selecting API 18,

1) restart the Eclipse ADT,

2) Open SDK manager, then API 18 rev 1 shall appear.
