Paparazzi crashing on compileSdk 36 (Android 16 Baklava)

[bardss]

Description
We are migrating our app to the newest compileSdk 36.
Android 16 got a Beta 3 release last week (13th March). The first release that reached platform stability and was not released as a preview.

https://developer.android.com/about/versions/16

After setting compileSdk to 36 our screenshot tests are failing.

There are two different types of crashes/stacktraces that I can share:
1‍⃣ :

java.util.NoSuchElementException: Array contains no element matching the predicate.
	at app.cash.paparazzi.internal.Renderer.configureBuildProperties(Renderer.kt:213)
	at app.cash.paparazzi.internal.Renderer.prepare(Renderer.kt:108)
	at app.cash.paparazzi.PaparazziSdk.prepare(PaparazziSdk.kt:128)
	at app.cash.paparazzi.Paparazzi.prepare(Paparazzi.kt:89)
	at app.cash.paparazzi.Paparazzi$apply$1.evaluate(Paparazzi.kt:77)
	at com.google.testing.junit.testparameterinjector.PluggableTestRunner$ContextMethodRule$1.evaluate(PluggableTestRunner.java:414)

2‍⃣ :

kotlin.UninitializedPropertyAccessException: lateinit property sessionParamsBuilder has not been initialized
	at app.cash.paparazzi.PaparazziSdk$Companion.getSessionParamsBuilder$paparazzi(PaparazziSdk.kt:596)
	at app.cash.paparazzi.PaparazziSdk.prepare(PaparazziSdk.kt:132)
	at app.cash.paparazzi.Paparazzi.prepare(Paparazzi.kt:89)
	at app.cash.paparazzi.Paparazzi$apply$1.evaluate(Paparazzi.kt:77)
	at com.google.testing.junit.testparameterinjector.PluggableTestRunner$ContextMethodRule$1.evaluate(PluggableTestRunner.java:414)

The run always starts with the 1‍⃣ crash and all the next follow along with 2‍⃣.
Looks like Renderer.kt in configureBuildProperties is trying to get the code through reflection that is not available in Android 16.

Steps to Reproduce
Update the compileSdk to 36 and run the tests.

Expected behavior
Tests not crashing.

Additional information:

• Paparazzi Version: 1.3.5
• OS: Android 16
• Compile SDK: 36
• Gradle Version: 8.12.1
• Android Gradle Plugin Version: 8.9.0

Also affected by it, hope to see it fixed soon because new versions of androidx libraries are starting to require compileSdk 36 which breaks our screenshot tests :)

[TWiStErRob]

@StepByStepler are those AndroidX libs alpha/beta, or stable ones? (Just curious)

[StepByStepler]

@TWiStErRob It's an alpha version (currently only one dependency), but in our production app we tend to use the latest alpha versions of androidx dependencies if available, because they are alpha mostly due to API stability, not runtime stability or bugs

Hello folks! Firstly, many thanks for this great tool ❤

Regarding this issue, I've been digging and managed to "fix" it.
It seems that on SDK 36 the class android.os._Original_Build doesn't declare the class VERSION_CODES_FULL.

The change I made (which I'm not sure it's the correct one) is to change the iteration over buildClass.classes in Renderer, to filter out the class whose simpleName equals VERSION_CODES_FULL.

With this change, all tests in the sample module seem to pass when compileSdk is set to 36.

I'd be happy to provide a PR/patch with the change, assuming this is the correct approach.

Hi there, I'm facing the same issue

It would be great to see this fixed before Android 16 is released.
Are there any plans to address this? Is there anything we can do from the client side to handle this?

After trying out 2.0.0-alpha01 version, when using compileSdk = 36 it seems that the crash has been fixed 🚀

[JeremiahStephenson]

I'm also having the same issue and I tested 2.0.0-alpha01 today and it does not fix it for me. I continue to experience UninitializedPropertyAccessException.

[NunoPontes]

Yap, even on 2.0.0-alpha01 I get the same two issues :(

[Thanasis17m]

I've also verified that the aforementioned two issues are reproducible in 2.0.0-alpha01. 🙏

FWIW, no issue to report on any of the 2.0.0-SNAPSHOTs versions, and I'm pretty sure this was fixed by this PR (merged just after the 2.0.0-alpha01 release):

• Update layoutlib to v15.2.2 #1885
