For View's onClick attribute the method must have a single argument of type android.view.View. For a MenuItem's onClick attribute the method must have a single argument of type android.view.MenuItem. Since these rules match all types and any return type, matching by signature is the only available specificity that can be added.

Reflection-based instantiation of manifest-declared types is only done on the default (aka no-argument) constructor. While these types are unlikely to have alternate constructors (unlike the others listed in the bug), there's no reason to generate overly keep-y rules for them.

Adds generation of proguard rules for fragments in res/navigation. All
android:name attributes have keep rules generated for the classes they
reference.

Add the option to produce keep rules that conditional keep based on
usage of R identifiers. This allows Proguard to potentially shrink more
code if resources are not used.
Currently only produces conditional rules for classes referenced in
layout resources because they are the most common and has the easiest
transitive usage chain to analyze.

<fragment> tags in layouts use the class attribute to determine which
Fragment subclass to load, and fallback on android:name if class is not
set.
AAPT2 only emitted a proguard rule for the class attribute for <fragment>,
when it should emit a proguard rule for the android:name attribute as
well.
AAPT2 didn't handle menu XML, so support for actionViewClass,
actionProviderClass and onClick is added.
