Please rename the key file to: chromium-apk-debug.keystore

[cjhopman, 2012/09/10 18:21:41]

Done. Also changed passwords and alias to chromium instead.

Did you intend to change this for patch set 2?

We use 100 columns for ant build files.

This does not fit in 100 chars.
Please add a line break before "depends"

Done.
