From b3240df7c525de985765e0cbbb094a0f7c83e440 Mon Sep 17 00:00:00 2001 From: Joshua Trask Date: Fri, 10 Feb 2023 16:25:01 +0000 Subject: Clarify ResolverActivity inheritance contract. This is a simple mechanical refactoring and (given everything still builds) it can't possibly have any side effects. The procedure for generating this change was as follows: 1. Add `final` to all `ResolverActivity` methods. 2. Build, and remove `final` from any of those methods that now break compilation. 3. Sort the `final` (and `static`) methods to the bottom of the source file / non-final to the top. 4. Build `IntentResolverUnitTests` and remove `final` from any `ResolverActivity` methods that broke test-only compilation. Replace with a comment `// @NonFinalForTesting` on these methods (referencing an annotation that isn't available in Android, but still worth noting. There are other patterns we can use to formalize our design requirements, but these lightweight comments are more appropriate while the API is in flux). 5. Sort these "non-final for testing" methods above the `final` methods but below any that are overridden by real clients (since they're still *really* just internal implementation details). 6. Build and test. (7. Go back through and remove `final` from any private methods, as requested by the linter. I'm not sure I agre3 with this rule in a language where these methods will be "open" by default if their visibility is ever changed, but c'est la vie...) This groups together the `ResolverActivity` "override surface," which roughly outlines the interface of a hypothetical delegate interface that could be injected as part of `ChooserActivity` configuration in order to avoid overriding any `ResolverActivity` methods. (That's left out of scope in this CL, because -- even though we *could* effect such a change via purely-mechanical transformations -- I suspect we'll want to apply *some* design discretion along the way.) Ultimately this will be an important step in decoupling our components from the `Activity` API (with benefits for code clarity, hypothetical "embedded Sharesheet" and "build-your-own chooser" APIs, etc).
