I've tested this and currently you do not need to enable proguard for the
Android Library project. In fact, I think the proguard files and the
project.properties files for the library project are unused. What matters
is the files in your Application Project. Whatever conditions you set in
those files will be applied to your referenced Project Libraries as well.
Keep in mind that with the new SDK Tools change the way the Proguard config
files are used. They split it into two files and also changed the names.
There is one file called proguard-android.txt in the
SDK\tools\proguarddirectory and one called
proguard-project.txt in your project directory.
Which files get used is determined in your Application projects
project.properties file. There is a line you need to uncomment to enable
Proguard (it is off by default):
proguard.config=${sdk.dir}\tools\proguard\proguard-android.txt:proguard-project.txt
As you can see by default it will combine the flags and settings in those
two files to create your proguard configuration. This only applies to new
projects created with the newer SDK/ADT tools.
