Cannot run program “/opt/android-sdk/platform-tools/aapt”

It seems that Google did a big reorg of the Android SDK file tree, and some tools still expect things in the old locations, like our Jenkins build server:

Luckily there are symlinks! This fixed it for me:


cd /opt/android-sdk
ln -s 18.0.1 build-tools/current
ln -s ../build-tools/current/aapt platform-tools/aapt
ln -s ../build-tools/current/lib platform-tools/lib


Then whenever the build-tools get updated, just the symlink in /opt/android-sdk/build-tools/current needs to be updated. This is a little improvement on the solution found here.
