Android - Unknown build error message

Unity Engine
,

I got the following error on android platform with Unity 4.1.5f1

Any ideas?

Are your JDK and Android sdk correctly installed?

Yes.

As shown on Android SDK Manager, ‘Android SDK Tools r22.01’ is installed.

And the SDK path is correctly set in the Unity’s preference.

Couldn’t find any related answer for the above error even with googling.

Solved the problem by downgrading Android SDK Tool to r21 from r22 as the following post says:

By the way, the following post by Unity support says that Unity 4.1.5f1 solved the android build error problem but it seems that the above is another unknown error.
