The backporting in the blocking bugs has been implemented and is part of R8 8.1.34-dev landing in Studio with https://googleplex-android-review.git.corp.google.com/c/platform/prebuilts/r8/+/22378102.

However, Lint still adds red squiggles in code like this:

    try (TypedArray typedArray = resources.obtainTypedArray(R.array.colors)) {
        System.out.println("Got TypedArray with " + typedArray.length() + " elements.");
    }

I have checked, and the generated backported methods list (that lint gets from AGP) contains the following line:

android/content/res/TypedArray#close()V

For Kotlin, with use the code looks like this:

    resources.obtainTypedArray(R.array.colors).use { it -> "Got TypedArray with ${it.length()} elements." }

Here lint does not add any red squiggles neither with or without the backport. However, the backport does not currently work with use. This is tracked in b/276434250.

The attached project has a TypedArray and JavaTryWithResources.java and KotlinUse.kt using it.

Yep, this is now fixed in lint for the next canary. (Change-Id: Ife13e93be081e222def613aa641173bb9ad262f2)
