🚧 AGP 9 #1959

SimonMarquis · 2025-09-14T12:35:25Z

This neat website can be used to track the current issues with AGP 9: https://agp-status.frybits.com/agp-9.0.0/

Firebase Perf Plugin does not work with latest AGP 9 alpha firebase/firebase-android-sdk#7293 (fixed in Firebase BoM 34.5.0)
AGP 9.0.0-alpha03 produces circular dependency on KSP tasks
fixed in KSP 2.2.20-2.0.3

Avoid using old Variant API extending JavaCompile task gradle/android-cache-fix-gradle-plugin#1886
Temporary workaround with android.newDsl=false

> Failed to apply plugin 'org.gradle.android.cache-fix'.
   > Could not get unknown property 'unitTestVariants' for object of type com.android.build.gradle.internal.dsl.ApplicationExtensionImpl$AgpDecorated.

Regarding AGP 9 and built-in Kotlin. google/ksp#2615 (fixed in KSP 2.3.1-SNAPSHOT)
Hilt Gradle Plugin does not work with AGP 9.0.0-alpha04 google/dagger#4944
Temporary workaround with android.newDsl=false

release build type has isDebuggable forced to true, even when explicitly turned off.

AGPBI: {"kind":"warning","text":"BuildType 'release' is both debuggable and has 'isMinifyEnabled' set to true.\nAll code optimizations and obfuscation are disabled for debuggable builds.","sources":[{}]}

fixed in 52b118a

WARNING: Unsupported Kotlin plugin version.
The `embedded-kotlin` and `kotlin-dsl` plugins rely on features of Kotlin `2.2.0` that might work differently than in the requested version `2.2.10`.

Update to Gradle 9.2.0 to fix the issue.

build-logic/convention/build.gradle.kts

`error: cannot find symbol` on: - `DataStoreModule.INSTANCE.providesUserPreferencesDataStore$datastore_demoDebug` - `SyncModule.Companion.provideFirebaseMessaging$work_prodDebug()`

They must have been removed as they are no longer resolved by default.

Updated Android Gradle Plugin and Tools versions.

(included in firebase-bom 34.5.0)

release build type has isDebuggable forced to true, even when explicitly turned off.

Can you point me to how to repro this?

SimonMarquis · 2025-11-06T18:13:41Z

I've not been able to reproduce it on my other projects, but on this one, simply build a release app with gradlew :app:assembleDemoRelease.

not sure if they were dropped on purpose...

…buildTypes leading to "debuggable" release builds.

SimonMarquis · 2025-11-07T20:58:48Z

I found the issue, fixed in 52b118a.
enableAndroidTestCoverage forces the app to be debuggable, probably because of a new logic internal to AGP.

I've refactored the code to configure only the debug buildTypes:

Why is this change needed? Is it related to the AGP upgrade?

Yes, see this commit: fd939d5

Add a comment on why we need to opt out linking to the hilt bug.

This is not meant to be merged as-is, as mentioned in the PR first message.
That being said, if you really want to merge this PR before alls bugs are fixed & workarounds are removed, I can add a comment for this. Let me know.
