Error generating final archive: Unable to get debug signature key

I cannot build and run my android project using Eclipse on mac 10.7. The error I receive is

Error generating final archive: Unable to get debug signature key

• Changed the permissions in the ~/.android directory with no success.

• Tried generating another project

• Followed the guide of setting up an SDK and was even successful in a windows environment for my windows terminal at my workplace.

• Installed the packages using AVD and ha开发者_如何学JAVAve set the location of my SDK location.

• Added my SDK tools to my $PATH variable.

I also receive another error when I try to Create AVD

[2011-10-08 13:42:17 - SDK Manager] Error: null

What other step have I missed?

---

Deleted the ~/.android directory, re-run AVD manager and then rebuild project.

Removing the directory, re-running the AVD manager, and rebuilding didn't fix this problem for me, and best I can tell, it's related to directory permissions.

When I let the AVD manager or keytool.exe create my .android directory, the permissions on the directory were:

d---------

In my case, I

1. removed the .android directory
2. mkdir .android
3. build and run.

Since I was running from eclipse with the ADT plugin, it prompted me to create a new virtual Android device (since it stores them in the .android/avd directory). And this time, file permissions on .android and everything else came out fine.

Was getting Error: null when creating AVD using the OSX Android dev bundle. Bundle was installed in /dev folder in Desktop folder - /Users/me/Desktop/Dev . Needed to create .android folder in user folder - /Users/me/.android .
