View inflation error

[arturdryomov]

I’m trying to work with the application module and Spek, so this is destined to fail, but anyways. Since #105 blocks me from using the Paparazzi Gradle plugin, I’m doing what the plugin does on my own.

view_basic.xml

<?xml version="1.0" encoding="utf-8"?>
<View
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    />

PaparazziSpec.kt

describe("paparazzi") {

    val paparazzi by memoized { Paparazzi() }

    beforeEachTest {
        val resourcesFile = File("REDACTED_MODULE_PATH/build/intermediates/paparazzi/resources.txt")
        val resources =
                """
                REDACTED_MODULE_PACKAGE_NAME
                REDACTED_MODULE_PATH/build/intermediates/res/merged/debug
                """

        resourcesFile.apply {
            parentFile?.mkdirs()
            createNewFile()
            writeText(resources.trimIndent())
        }

        paparazzi.prepare(Description.createTestDescription(PaparazziSpec::class.java, "paparazzi"))
    }

    it("should work") {
        paparazzi.snapshot(paparazzi.inflate(R.layout.view_basic), "basic")
    }

    afterEachTest {
        paparazzi.close()
    }
}

It actually compiles but fails to proceed.

kotlin.TypeCastException: null cannot be cast to non-null type V
    at app.cash.paparazzi.Paparazzi.inflate(Paparazzi.kt:128)
    at PaparazziSpec$1$1$2.invoke(PaparazziSpec.kt:42)

I’ve explored with a debugger a bit and seems like BridgeInflater#inflate returns null

• since bridgeContext.getRenderResources().getResolvedResource(layoutInfo) returns null
• since RenderResources#getResolvedResource returns null
• since RenderResources#getUnresolvedResource returns null
• since ResourceResolver#getUnresolvedResource returns null
• since getResourceValueMap(reference.getNamespace(), reference.getResourceType()) returns empty map

That's correct behavior at the moment, unfortunately. This stems from how application modules compile and merge resources vs how library modules does it. Explained here: #105

Tracked in #107
