4 years ago aapt2 optimize doesn't look to be documented yet.
Help output:
> aapt2 optimize --help
aapt2 optimize [options] files...
Options:
-o arg Path to the output APK.
-d arg Path to the output directory (for splits).
-x arg Path to XML configuration file.
-p Print the multi APK artifacts and exit.
--target-densities arg Comma separated list of the screen densities that the APK will be optimized for.
All the resources that would be unused on devices of the given densities will be
removed from the APK.
--resources-config-path arg Path to the resources.cfg file containing the list of resources and
directives to each resource.
Format: type/resource_name#[directive][,directive]
-c arg Comma separated list of configurations to include. The default
is all configurations.
--split arg Split resources matching a set of configs out to a Split APK.
Syntax: path/to/output.apk;<config>[,<config>[...]].
On Windows, use a semicolon ';' separator instead.
--keep-artifacts arg Comma separated list of artifacts to keep. If none are specified,
all artifacts will be kept.
--enable-sparse-encoding Enables encoding sparse entries using a binary search tree.
This decreases APK size at the cost of resource retrieval performance.
--collapse-resource-names Collapses resource names to a single value in the key string pool. Resources can
be exempted using the "no_collapse" directive in a file specified by --resources-config-path.
--shorten-resource-paths Shortens the paths of resources inside the APK.
--resource-path-shortening-map arg Path to output the map of old resource paths to shortened paths.
-v Enables verbose logging
-h Displays this help menuWe would probably have to read aapt2's source code to figure out how to use this...
@CayasSoftware if you can figure out how to run it command-line against your app, that would help a lot. To get an idea of the file savings?

aapt2 provides a parameter called
optimizewhich optimizes resource files before they get packed inside the apk. A great explanation is given by Jake Wharton on his blog post Smaller apks with resource-optimization.I think this might be a great opportunity for Xamarin.Android apps, because the build process make use of aapt too. I am not sure how this could be integrated exactly but in my understanding it my be possible to "just" add a new step to msbuild.
