SDK build Tools version 20 < 23

Hi there, I'm trying to build for Android, but it gives me the error: "SDK build Tools version 20 < 23"
It gives me the option to update, but that's useless,

Things I tried to do to fix this:

Downloaded the sdk version 23 API using the SDK manager.
Made sure Unity knew the correct path to the Android SDK.

I don't know what else to do.

My unity version is 5.5.0f3

Edit: I tried to just hit: "Continue", but now it says: "Moving file failed"

Moving Temp/StagingArea/Data to Temp/StagingArea\assets\bin\Data: Access is Denied.
I'm running Unity as administrator.

I tried doing a "build and run" with a device connected, it tells me I need to name the bundle:

com.companyname.productname, so I do that, and it still gives me the error.

Has anyone succeeded at building for Android in Unity 5.5?

 

Can you please post the full error message (from the editor log) ? I will be able to assist better after i see that.

It can also be helpful to see the full editor log, as the build process outputs some of the "decisions" it takes like where your Android SDK is installed, what JDK its using, etc.

 

*** Cancelled 'Build.Player.AndroidPlayer' in 29 seconds (29400 ms)

That's not very helpful.

 

That is not the full editor log file. You should quit the editor, relaunch it and repeat the build scenario.

Once it fails, get the log (see the path to it here).

 

That's weird, it just suddenly stopped giving me that error. It told me to name my company in the player settings instead. The company name I had put started with a number, which is a no-no.

 

problem fixed here :
