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:

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.

update your IntelliJ to 12.1.4 by using beta releases as the update channel

In Windows it is enough to copy only aapt.exe, lib\dx.jar and dx.bat

from build-tools\android-4.2.2

to

platform-tools

The same problem occurred for me with android-studio. But, this probably applies to the IntelliJ IDE as well.

When checking the file location I saw, however, that aapt was in the expected location.

In my case the issue was that I was running a 64-bit Ubuntu linux system which cannot execute the 32-bit aapt executable.

Installing 32-bit compatibility libraries solved this issue in my case: sudo apt-get install ia32-libs
