Every time I try to export an APK from Eclipse (tried Juno and Indigo) on Mac, eclipse crashes after a few seconds
This used to work fine on my current setup.
<Disable Project->Build Automatically
. I've noted that this works for me.
Disable Project/Build Automatically when you are exporting
I think is a problem of Eclipse unable to detect the Android command is still working or something similar.
Of course there is ever the option of APK generation using Ant outside Eclipse you can generate an Ant build.xml from your Eclipse project more info in official Android docs
