i am trying to build angrybots
(was working fine before upgrade)

now i have got the error below

notes: 1. there isn’t any c:\buildagent directory, i assume it’s just a temporary
created on the spot ?
2. path to android sdk is set in preferences, but it keeps asking for android sdk path everytime
i try to build

Hello linxuzi,

I have exactly the same problem. Since I change the version from 3.5.4 to 3.5.7, my project doesn’t want to build it anymore with the same error message.
Did you find a solution?
Or anybody else could give an answer please?

Thank you in advance.

Most likely unity picks up some old jdk version. Try to set the JAVA_HOME environment variable to a jdk 6 installation.

It is a probleme with jdk version, if you installed a newer version you need to add the PATH and the CLASSPATH to the environment variable and JAVA_HOME too and then downgrade anrdoidsdk to r21 because android sdk r22 is not compatible with unity 4.0
