问题:

I just installed android 2.1 SDK in eclipse and created a project targeted for Google API:7. Eclipse shows an error on the project icon, and the debug window shows this error

ERROR: Unknown command 'crunch' Android Asset Packaging Tool

After quite a lot of googling, I still have no idea how to fix this error. I have already tried cleaning up the project.

回答1:

I think the problem has a generic cause ==> Partial ADT Update

Check your repositories again and then this link

回答2:

This happened to me too when I updated Eclipse from Helios to Indigo (on Windows XP)

Solution was to open Android SDK Manager and install all the default selected updates, notably I was on

Android SDK Tools rev 13
Android SDK Platform Tools rev 7

These updated to

Android SDK Tools rev 14
Android SDK Platform Tools rev 8

My project which targets 2.2 compiles and runs in debug now without any problems (NB I have all the SDKs installed including 4.0 but you can still target earlier SDKs)
