build: Bump AGP to 9.2.1 and migrate Android modules by runningcode · Pull Request #5779 · getsentry/sentry-java

runningcode · 2026-07-16T17:01:42Z

We need to bump AGP to 9.2 because compile SDK introduced a breaking change (37.0 vs 37) which makes it very difficult to compile using AGP 8.X.

AGP 9.X introduced several breaking changes that we try to mitigate in this PR.

AGP 9.X sets the java target compile level to 11 from 8, so we override this to keep the same level.
AGP 9.X includes a bundles kotlin plugin, we disable this with android.builtInKotlin=false
AGP 9.X has a new DSL which we disable with android.builtInKotlin=false
AGP 9.X disables unit tests for debug variants. we therefore set the test variant to release in modules where debug is disabled.
Fix and ignore some AGP 9.X lint warnings

Fixes #5777

-  kotlin { compilerOptions.jvmTarget = org.jetbrains.kotlin.gradle.dsl.JvmTarget.JVM_1_8 }
+  // AGP 9 only generates unit tests for the testBuildType. CI disables the debug
+  // variant, so unit tests must target release to run at all.
+  testBuildType = "release"


Release tests forced outside CI

Medium Severity

testBuildType = "release" is applied unconditionally, but debug variants are only disabled in CI via shouldSkipDebugVariant. Locally, that removes testDebugUnitTest even though debug is still enabled, so the documented testDebugUnitTest workflow no longer works.

Raise the minimum AGP to 9.0.0 (default fallback 9.2.1) and perform the AGP 9 migration: refresh the AGP-compat matrix (9.0.0/9.1.1/9.2.1), add the AGP 9 opt-outs (android.builtInKotlin/newDsl, lint 9.2.1), pin Java and Kotlin targets to 8 across the Android library modules, set testBuildType to release for unit tests (including sentry-compose), bump the uitest modules to JVM 11, and resolve the AGP 9.2 lint findings. Robolectric 4.15 caps at API 35, so pin the affected tests with @config(sdk = [35]) to keep them green against targetSdk 36. lint 9.2.1 flags compileSdk 36 as outdated (37 is available); disable GradleDependency for the Android modules since the SDK bump lives in the API 37 PR. Split out from the API 37 bump (#5768) so the toolchain upgrade lands on its own. compileSdk/targetSdk stay at 36 here.

reminder: we publish the entry-android artifact compiled against 9.2.1 as set in Config.kt below. this test compiles the sentry-android artifact against different versions of AGP meaning the tests do not represent our published artifact

we should investigate and/or update robolectric to fix the failure this was causing in a separate PR

AGP defaults to 11 now. Since these are our UI tests, it doesn't affect the compiled artifact.

just a random fix here, this should be declared on the kotlin extension not the task like all the other modules

I'm guessing the failing snapshot test diff is due to a bump in layoutlib which mustve changed the default theme from dark to light: https://github.com/getsentry/sentry-java/pull/5779/checks?check_run_id=87875970201

I went ahead and approved it. I don't think it is worth investigating
