Yeah according to Simon in
Android Hello-World compile error: Intellij cannot find aapt
"It appears that the latest update to the r22 SDK release moved aapt and the lib jar from the platform-tools to the build-tools directory. While we wait for JetBrains to release an update, here's a quick fix using a couple of symbolic links for Unix users:
From your AndroidSDK/platform-tools directory, run the following:
ln -s ../build-tools/17.0.0/aapt aapt
ln -s ../build-tools/17.0.0/lib lib
...and IntelliJ should be able to compile as normal.
"
Unfortunately copying is the easier way around this on windows...
unless you use something like
mklink /H C:\Users\Tom\androidsdk\build-tools\17.0.0\aapt.exe C:\Users\Tom\androidsdk\platform-tools\aapt.exe
in the command prompt to attempt to make a hard link window's style of the file to your platform tools folder.
caveat I haven't tried this though...
