created issue #1

Jul 26, 2020 07:08AM

Component used: Fragment
Version used: 1.3.0-alpha07
Devices/Android versions reproduced on: N/A

This code snippet will no longer work with lint tools 27.1.0+ (which is what's used in AGP 4.1.0+).

https://github.com/androidx/androidx/blob/c5ff35e40fbf353262ac22013e8c16e45b9017a3/activity/activity-lint/src/main/java/androidx/activity/lint/ActivityResultFragmentVersionDetector.kt#L97

It looks like it should be changed to buildVariant, and then there are changed APIs for accessing library info (the .libraries call at the end will also need fixing).

This results in the following failure when I build with newer lint tools and AGP 4.1.0-beta05 in our project

NoSuchMethodError:ActivityResultFragmentVersionDetector.checkDslPropertyAssignment(ActivityResultFragmentVersionDetector.kt:97)←Detector.checkDslPropertyAssignment(Detector.kt:418)←UastGradleVisitor.handleMethodCall(UastGradleVisitor.kt:190)←UastGradleVisitor.access$handleMethodCall(UastGradleVisitor.kt:34)←UastGradleVisitor$visitBuildScript$1.visitCallExpression(UastGradleVisitor.kt:40)←KotlinUFunctionCallExpression.accept(KotlinUFunctionCallExpression.kt:205)←ImplementationUtilsKt.acceptList(implementationUtils.kt:23)←UBlockExpression$DefaultImpls.accept(UBlockExpression.kt:21)

Ensure check fails on all calls to regsiterForActivityResult

Although fixing one of the errors will fix them all, we should still
make sure we show the errors on all of the calls to
registerForActivityResult, not just the last one.

Marked as fixed.

This has been fixed internally and will be available in the Activity-alpha08 release.

Remove code path for older lint versions and reflection

When the ActivityResultFragmentVersionDetector was written there had
been recent changes in the lint API that required it to be supported in
2 incompatiable lint versions (see

b/162155191

). That was over 3 years
and 4 lint versions ago, but it required the use of some unsafe
reflection.

Enough time has passed that it is reasonable to expect that most people
using the latest version of the Activity library are also using some
more recent version of lint.

We can clean up this rule by removing the old lint path and relying
directly on lint API instead of reflection.

This also reenables some tests that were failing due to bugs in previous
lint versions.

RelNote: "The `InvalidFragmentVersionForActivityResult` lint check will
now only work on AndroidStudio versions 4.1.0+."
Test: reenabled tests
