After upgrading to Android Studio Jellyfish, and updating the Android Gradle Plugin 8.4.0, on a multi-module project I can't seem to inject into my Service any more when minify in enabled.
After the upgrades, I spent quite a bit of time adding new rules to the non-app modules (they are aar modules). I now have the app running, and most of the features working again. But I can't get the service working. It has quite a few things injected into it. Since it worked with the previous version of AGP, and it works with a debug build, I assume it's due some missing rule that's needed to due the new version of AGP. It really acts it doesn't see the annotations. I have the same rules in this module for keeping the annotations as I do in other modules, and they are getting their injections.
I've reduced the service to:
@AndroidEntryPoint
open class MyService : Service() {
@Inject
lateinit var test: DTest
override fun onCreate() {
super.onCreate()
Timber.d("onCreate, ${test.test}")
}
override fun onBind(intent: Intent?): IBinder? {
return null
}
}
Where DTest is in the same module and is just:
@InstallIn(SingletonComponent::class)
@Module
object TestModule {
@Provides
@Singleton
fun providesDTestModule(): DTest {
return DTest("TestModule")
}
}
data class DTest(val test: String)
When the service is started, this is the result:
E java.lang.RuntimeException: Unable to create service my.package.MyService: kotlin.UninitializedPropertyAccessException: lateinit property test has not been initialized
E at android.app.ActivityThread.handleCreateService(ActivityThread.java:4664)

E ... 9 more
These rules got me past the problem:
-keep class my.pkg.name.di.** { *;}
-keepclassmembers my.pkg.name.di.** { *; }
-keep class my.pkg.name.MyService* { *; }
where my.pkg.name.di is package where I keep my dagger modules
Note that the keep on the service alone didn't work, I had to add an asterisk at the end to make sure some of the hilt generated class were kept. In fact, that was the key to getting this working.
I might be wrong, but my sense is dagger needs to update their rules for the new version of the AGP.
