You got rid of the -e but didn’t put in a “set -e” as I asked.

It’s a very good idea to run your scripts under -e.

Seems like this could end in ${SDK_FILE_NAME}. Same on line 29.

This just drops stuff into the current directory. The current directory could be
anything! That’s no good. This should probably work with some sort of temporary
directory. You can get a temporary directory with TEMPDIR=$(mktemp -d). Be sure
to remove your temporary directory when the script exits, whether it’s a clean
exit or not.

This doesn’t need to end in a comma.

You might want to print the expected and computed MD5 checksums. You could stick
the result of $(md5sum …) into a variable like computed_md5, compare that to
md5, and then echo them both out on this line.

If you’re running under -e, the script will die before it gets to this point, so
you can get rid of this check.

Usually you just wrap the quotes around the entire word, not just the variable
expansion, like "${ANDROID_SDK_ROOT}/tools/android". Same on line 95 and 103.

[michaelbai, 2011/10/06 17:23:19]

Done, Shall I know what's the difference?
