Should we adjust this message to say something about the path not existing?

Changed the message to include the missing path and to be more specific

…t is missing

Test change LGTM.

Seems reasonable. Over at #160372 (comment) on the issue, you wrote:

Interestingly it looks like the AGP maintainers sort of disagree, and explicitly say not to to put the external native build output directory in your projects temporary build directory. I think it probably isn't a problem for us, though, as we aren't actually building anything anyways (we are just tricking AGP into downloading the NDK).

Did they say that anywhere that can be linked to? I'm curious also if they added anything about their thinking on why putting it in the temporary build directory is undesirable.

Yes, should have included the link but it is in
https://developer.android.com/reference/tools/gradle-api/8.3/null/com/android/build/api/dsl/Cmake#buildStagingDirectory(kotlin.Any)

If you specify a path that's a subdirectory of your project's temporary build/ directory, you get a build error. That's because files in this directory do not persist through clean builds. So, you should either keep using the default <project_dir>//.cxx/ directory or specify a path outside the temporary build directory.

Cool. If I'm reading that right, it's saying that that's a constraint which gets enforced — if you specify a directory it doesn't like by this criterion, then that's a build error. So if builds are nevertheless working with this change, then I guess there's no error to worry about.

And it sounds like the motivation is that they want these files to survive a gradle clean so that you don't sit there rebuilding them for a long time. As you said, that doesn't matter because we're not actually building anything.

Yeah I should have been clearer, I was

extrapolating the note in the AGP docs based on assumed motiviation from (you shouldn't use the specific build/ subdirectory that AGP knows about) to (you shouldn't use any build/ subdirectory)

resolving that extrapolated concern by saying we aren't building anything anyways.

Will update the comment to be clearer

gnprice

LGTM, thanks!

I'd suggest expanding the comment a bit with the reasoning you gave in the thread.

Oh and I think the same PR can remove the .cxx entry from the template gitignore. If someone creates a project with a new Flutter that has this change, they're probably not going to later run it on an older Flutter (and I think in general we don't guarantee that that even works).

I think I lean towards not removing them from the templates as

Projects which actually configure a native build will still have the .cxx directory at android/app/ (i.e., we only move it if it is only being used for tricking AGP to download the NDK).
(pure) Android templates defaults to gitignoring this directory, so Android defaults would gitignore it in this case.

WDYT?

gnprice · 2025-03-31T22:11:52Z

That makes sense — that's a good reason to continue to include it in the template gitignore.

Dang. The docs you found said there'd be an error:
#166277 (comment)

and since the build wasn't failing, we knew we weren't causing that to trigger. But if the docs aren't quite right and it's actually a warning, then that reasoning doesn't apply.

gmackall · 2025-04-05T07:17:22Z

It looks like the warning is specifically complaining about the build/app subdirectory. Perhaps I can try giving it its own subdirectory in build/.

Will try it out on Monday

gmackall · 2025-04-08T19:04:42Z

The follow up issue should be fixed by #166727

Fixes/suppresses all warnings: 1. Fixes #162695 2. Suppresses warnings about the various `*Variant*` imports that we use being deprecated, with comments linking to #166550 to migrate to the variant api. 3. Fixes some unused elvis operators and unneeded types provided for declarations that AGP complains about, e.g. `val fooString: String = "a string"`, and use of deprecated string related methods. 4. Follows up on #166277, as we were getting a warning mentioned in this comment #166277 (comment). 5. Suppresses some warnings about unused code where the analysis couldn't properly detect it being used (i.e., it isn't unused) (4) is more opinionated, let me know if you think it should be done in a follow up. ## Pre-launch Checklist - [x] I read the [Contributor Guide] and followed the process outlined there for submitting PRs. - [x] I read the [Tree Hygiene] wiki page, which explains my responsibilities. - [x] I read and followed the [Flutter Style Guide], including [Features we expect every widget to implement]. - [x] I signed the [CLA]. - [x] I listed at least one issue that this PR fixes in the description above. - [x] I updated/added relevant documentation (doc comments with `///`). - [x] I added new tests to check the change I am making, or this PR is [test-exempt]. - [x] I followed the [breaking change policy] and added [Data Driven Fixes] where supported. - [x] All existing and new tests are passing.

Fixes/suppresses all warnings: 1. Fixes flutter#162695 2. Suppresses warnings about the various `*Variant*` imports that we use being deprecated, with comments linking to flutter#166550 to migrate to the variant api. 3. Fixes some unused elvis operators and unneeded types provided for declarations that AGP complains about, e.g. `val fooString: String = "a string"`, and use of deprecated string related methods. 4. Follows up on flutter#166277, as we were getting a warning mentioned in this comment flutter#166277 (comment). 5. Suppresses some warnings about unused code where the analysis couldn't properly detect it being used (i.e., it isn't unused) (4) is more opinionated, let me know if you think it should be done in a follow up. ## Pre-launch Checklist - [x] I read the [Contributor Guide] and followed the process outlined there for submitting PRs. - [x] I read the [Tree Hygiene] wiki page, which explains my responsibilities. - [x] I read and followed the [Flutter Style Guide], including [Features we expect every widget to implement]. - [x] I signed the [CLA]. - [x] I listed at least one issue that this PR fixes in the description above. - [x] I updated/added relevant documentation (doc comments with `///`). - [x] I added new tests to check the change I am making, or this PR is [test-exempt]. - [x] I followed the [breaking change policy] and added [Data Driven Fixes] where supported. - [x] All existing and new tests are passing.
