Android Build Process Error

Hello, I'm busy making an Android app for a company, but when I was going to test it on my Galaxy S2, it didn't go right and it gave this error:

[ERROR] :  Build process exited with code 1
[ERROR] :  Project failed to build after 895ms

This is my log file:

Logfile initialized

I tried reinstalling Titanium and I reinstalled the Android SDK, does anyone know a solution? I'm using an iMac from late 2012 and the newest version of Titanium.

Thanks!
