IssueTracker

Tested on Android 12 Emulator with custom executor, but cannot repro this issue.

1. Second crash in the description is from a real device. Experienced it myself on two different Xiaomi phones, plus lots of crashes from users in the Google Play console.

2. Dynamic features are not used in the application.

As a wild guess, I have downgraded build tools from 31.0.0 to 30.0.3, compileSdk from 31 to 30, and moved all work with Language ID to the service in a separate process (just to be sure that crash can kill secondary process instead of main). This combination is in beta for 2 days by now and I don't see any SIGSEGV crashes.

Hmm, I feel the crash might be something related to separate/secondary process.

I also changed compileSdk and targetSDK to 31 but still cannot repro this issue.

On the contrary, there was no separate process before, when crashes started.

In the new build (with the aforementioned changes) I can see SIGSEGV crash, but only one instead of dozens and it has a bit different backtrace:

signal 11 (SIGSEGV), code 1 (SEGV_MAPERR)
liblanguage_id_jni.so (offset 0x11e000)

FYI, ML Kit launched a new language ID SDK in the latest release, which uses a new language ID model. https://developers.google.com/ml-kit/release-notes#august_11_2021

Could you try the new SDK version(17.0.0) to check if you can still repro this native crash? Thanks!

Thank you, I'll try it and check.

Hello. I have similar experience.

• I'm using mlkit-language 16.1.1
• I didnot meet this error until using AGP 4.2
• I can get this error since using AGP 7.0
• This error raised on Release build only(minimized by R8)
• This error raised without obfuscation.

Also I found there is a post which presents same issue on stackoverflow.

But after downgrade to AGP 4.2, crash is not reproducible.

$ git clone https://github.com/ganadist/VersionCodeDemo -b mlkit_agp42 mlkit_agp42
$ cd mlkit_agp42
$ ./gradlew :app:pPRUA
$ adb install app/build/outputs/universal_apk/productionRelease/app-production-release-universal.apk
$ adb shell am start -n com.example.myapplication/.MainActivity

Also, I tried to disable inline optimizers on R8 with AGP 7.0, and crash is not reproducible.

$ git clone https://github.com/ganadist/VersionCodeDemo -b mlkit_agp7_r8_disable_inline_optimizer  mlkit_agp7_r8
$ cd mlkit_agp7_r8
$ ./gradlew :app:pPRUA
$ adb install app/build/outputs/universal_apk/productionRelease/app-production-release-universal.apk
$ adb shell am start -n com.example.myapplication/.MainActivity

I tried the repro steps but got a NPE when I run ./gradlew :app:pPRUA

FAILURE: Build failed with an exception.

* What went wrong:
java.lang.NullPointerException
> java.lang.NullPointerException (no error message)

Could you also check if this is reproducible on 17.0.0 or 17.0.1? If yes, could you attach the full log that I can take a look? Thanks!

Here are gradle build scan logs for each branches.
All builds were clean build, and disabled build cache.

• mlkit_agp7 : https://scans.gradle.com/s/qrymdqfzwokbq
• mlkit_agp42 : https://scans.gradle.com/s/b6644hzfyfhaw
• mlkit_agp7_r8_disable_inline_optimizer : https://scans.gradle.com/s/c6h5hy2nxod4u
  • You can see R8 debug mode on build log : https://scans.gradle.com/s/c6h5hy2nxod4u/console-log#L95

Also, I pushed to update MLKit Language Id version 17.0.1 on mlkit17_agp7 branch And here is gradle build scan

• https://scans.gradle.com/s/ytaa2kkbp5vc4
  • Here is version of com.google.mlkit:language-id

And here is crash log after apply 17.0.1
You can see that BuildId of liblanguage_id_l2c_jni.so was changed from 859ec0ec2000a39e6ae8ed42e1704f46 to be6e59455cc10135330c93acdebfc121

Cross-posted on R8 issue tracker. https://issuetracker.google.com/issues/203573699

Hi,

Looks like we figured out the root cause in b/203573699

For temporary workarounds for the existing SDKs, you need to add this rule

-keep class com.google.mlkit.nl.languageid.internal.LanguageIdentificationJni { *; }

for language-id 16.1.1, and add this rule

-keep class com.google.mlkit.nl.languageid.internal.ThickLanguageIdentifier { *; }

for version language-id 17.0.0+ for the newer model.

We'll fix this issue in the upcoming release so that you'll not need these workarounds in the future release.

Thanks a lot for reporting this issue!

Added workarounds in Known issues section in public docs.

Hi! I'm still waiting for a quick solution to the problems generated in iOS

This is my data:

My db:

package features.configIni.data.database

import androidx.room.ConstructedBy import androidx.room.Database import androidx.room.RoomDatabase import androidx.room.RoomDatabaseConstructor

@Database( entities = [ WebServiceRoom::class ], version = 1 ) @ConstructedBy(WebServiceDatabaseConstructor::class) abstract class WebServiceDatabase: RoomDatabase() { abstract fun webserviceDao(): WebServiceDao }

expect object WebServiceDatabaseConstructor : RoomDatabaseConstructor<WebServiceDatabase>

const val DATABASE_NAME = "webService.db"

On Android, everything works fine but on iOS I get the error:

Expected WebServiceDatabaseConstructor has no actual declaration in module MatchAcademico:composeApp for Native

when according to the official doc it does not require me to set the actual declaration

I was able to build both Android/iOS with room = "2.7.0-alpha06".

I had to change composeApp/build.gradle.kts.

Solution

// libs.versions.toml

[versions]
kotlin = "2.0.10"
roomVersion = "2.7.0-alpha06"
sqlite = "2.5.0-alpha06"
ksp = "2.0.0-1.0.21"

[libraries]
androidx-room-compiler = { module = "androidx.room:room-compiler", version.ref = "roomVersion" }
androidx-room-runtime = { module = "androidx.room:room-runtime", version.ref = "roomVersion" }
sqlite-bundled = { module = "androidx.sqlite:sqlite-bundled", version.ref = "sqlite" }

[plugins]
room = { id = "androidx.room", version.ref = "roomVersion" }
ksp = { id = "com.google.devtools.ksp", version.ref = "ksp" }

// composeApp/build.gradle.kts

import org.jetbrains.kotlin.gradle.ExperimentalKotlinGradlePluginApi
import org.jetbrains.kotlin.gradle.dsl.JvmTarget
import java.util.Properties

plugins {
    ...
    // room
    alias(libs.plugins.ksp)
    alias(libs.plugins.room)
}

kotlin {
    ...
    sourceSets {
        ...
        iosMain {
            // To provide RoomDatabaseConstructor actual declaration
            kotlin.srcDir("build/generated/ksp/metadata")
            dependencies {
                ...
            }
        }
    }
}

dependencies {
    ...
    // Room
    add("kspCommonMainMetadata", libs.androidx.room.compiler)
    add("kspAndroid", libs.androidx.room.compiler)
}

room {
    schemaDirectory("$projectDir/schemas")
}

Create the following classes according to the official documentation.

https://developer.android.com/kotlin/multiplatform/room#defining-database

• shared/src/commonMain/kotlin/Database.kt
• shared/src/androidMain/kotlin/Database.kt
• shared/src/iosMain/kotlin/Database.kt

Build

1. Android Studio > Build > Clean Project
2. Android Studio > Build > Rebuild Project

Since this have changed a between alpha05 and alpha06 (and alpha07), please double check your build Gradle file configuration.

1. Please apply it to all your 'end' targets (this list is exhaustive but only use the ones relevant to your project):

dependencies {
    // Android
    add("kspAndroid", libs.androidx.room.compiler)
    // JVM (Desktop)
    add("kspJvm", libs.androidx.room.compiler)
    // Linux
    add("kspLinuxX64", libs.androidx.room.compiler)
    add("kspLinuxArm64", libs.androidx.room.compiler)
    // Mac
    add("kspMacosX64", libs.androidx.room.compiler)
    add("kspMacosArm64", libs.androidx.room.compiler)
    // iOS
    add("kspIosSimulatorArm64", libs.androidx.room.compiler)
    add("kspIosX64", libs.androidx.room.compiler)
    add("kspIosArm64", libs.androidx.room.compiler)
}

Note that applying the processor to the kspCommonMainMetadata should not be needed.

2. Do not manually add KSP generated sources from other targets:

// DO NOT DO THIS
iosMain {
   kotlin.srcDir("build/generated/ksp/metadata")
}

This just leads to errors due to the differences of generated code between the platforms, which is why its important that on step 1 the Room KSP processor is applied to all targets that will use the common sources set where the @Database is defined.

3. Do not declare explicit task dependencies:

// DO NOT DO THIS
kotlin.sourceSets.commonMain {
  tasks.withType<KspTaskMetadata> {
    kotlin.srcDir(destinationDirectory) 
  }
}

Declaring direct dependencies and adding generated sources by KSP is a red flag, these where workarounds from alpha05 that shouldn't be needed with the newer @ConstructedBy strategy in alpha06.

4. Do not create the actual of the expect object class that implemented RoomDatabaseConstructor

// shared/src/commonMain/kotlin/Database.kt
expect object MyDatabaseCtor: RoomDatabaseConstructor<MyDatabaseCtor> {
  fun initialize(): MyDatabaseCtor
}

// shared/src/nativeMain/kotlin/Database.kt
// DO NOT DO THIS
actual object MyDatabaseCtor: RoomDatabaseConstructor<MyDatabaseCtor> {
  fun initialize(): MyDatabaseCtor { ... }
}

5. Make sure Kotlin version matches KSP version, i.e. if using Kotlin 2.0.10 then use KSP 2.0.10-1.0.24

6. If using Kotlin 2.x then the kotlin.native.disableCompilerDaemon = true is not needed and can lead to another issue (https://youtrack.jetbrains.com/issue/KT-69523).

7. If you are using the Compose Gradle Plugin and Room Gradle Plugin along with Kotlin 2.0 then you might see a separate issue regarding the plugins along the lines of Cannot change attributes of configuration ':<project>:debugFrameworkIosX64' after it has been locked for mutation, the workaround is to remove the Room Gradle Plugin and configure the schema directory via KSP arguments, see https://issuetracker.google.com/343408758

8. If you had the workaround for clearAllTables(), please remove it, it is no needed since Room is being applied to 'end' targets.

Feel free to comment even if the steps mentioned here don't work for you.

I just followed the suggestions of da..@google.com on Aug 11, 2024 10:20AM, and modified my gradle, as well as not creating the 'current' of the 'expect object' and the only error I'm getting from XCode, since on Android everything works fine is the following:

null cannot be cast to non-null type org.jetbrains.kotlin.load.java.structure.impl.JavaClassImpl

These are my classes

@Database( entities = [ WebServiceRoom::class ], version = 1 ) @ConstructedBy(WebServiceDatabaseConstructor::class) abstract class WebServiceDatabase: RoomDatabase() { abstract fun webserviceDao(): WebServiceDao }

expect object WebServiceDatabaseConstructor : RoomDatabaseConstructor<WebServiceDatabase>

const val DATABASE_NAME = "webService.db"

If you are using Kotlin 2.0.10 please make sure you use matching KSP version 2.0.10-1.0.24

If you encounter an error with Cannot change attributes of configuration ':<project>:debugFrameworkIosX64' ... then please see the workaround in https://issuetracker.google.com/343408758#comment4

Another important thing is that kotlin.native.disableCompilerDaemon = true is not needed when using Kotlin 2.0.10, having it enable will lead to a different issue: https://youtrack.jetbrains.com/issue/KT-69523

Thank you very much for the prompt response, I really appreciate it!

I corrected your observations and I still have the same error in iOS Xcode,these are the logs I receive when I do the clean rebuild. I attached two images for a better look. Thanks for the support.

Thanks! These steps helped me fix Android and iOS. JVM is giving issues: Configuration with name 'kspJvm' not found.

Hello again da...@google.com Thank you very much for the prompt response, I really appreciate it!

I corrected your observations and I still have the same error in iOS Xcode,these are the logs I receive when I do the clean rebuild. My error is: null cannot be cast to non-null type org.jetbrains.kotlin.load.java.structure.impl.JavaClassImpl

I attached two images for a better look. Thanks for the support.

re comment#30 - Can you share your full stacktrace, by running ./gradlew :composeApp:kspKotlinIosX64 --stacktrace? The error null cannot be cast to non-null type org.jetbrains.kotlin.load.java.structure.impl.JavaClassImpl is new and might not be relevant to this specific bug.

re comment#31 da...@google.com

This is the full stacktrace:

re comment#32: Using Room is a library is about the same as using it in an application, the library ships the common code and the platform specific one that Room generates. I'll try to create a small sample app to demostrate it is possible.

re comment#34: In the stacktrace is shows KSP is crashing very early during Room annotation processing, please file a new bug as your issue is not quite related to the original issue described here.

e:file:///Users/..../kmp_project/zdckey_core/src/commonMain/kotlin/com/..../zdckey_core/data/database/ZDCKeyCoreDatabase.kt:21:8 Object 'ZDCKeyCoreDatabaseConstructor' is not abstract and does not implement abstract member 'initialize'.

Buddy. maybe you have some erros in ZDCKeyCoreDatabase.kt. You should not directly implement SDCKeyCoreDatabaseConstructor. You let it be just expect object.

Can you upload the declaration of SDCKeyCoreDatabase and implementation (in your case, it looks like you implement actual object) of ZDCKeyCoreDatabaseConstructor?

can I ask what proof_1.png source is located in? It should be in commonMain. If you can find the auto-generated actual object, can you upload?

Here is a sample project using Kotlin 2.0, Compose KMP and Room KMP 2.7.0-alpha06 in a library module: https://github.com/danysantiago/RoomKmpLibraryExample

I hope it serves as guidance, otherwise without a small repro project it is hard for us to point you in the right direction to fix your issue. Let me know if it is helpful.

In my opinion.. your compiler version doesn't support actual / expect. Can you check your Kotlin, KSP, Compose Version and talk to me?

After following all the guidance and checking the sample project I'm still getting: Object 'MyDatabaseCtor' is not abstract and does not implement abstract member 'initialize'

comment#43 When running the app, it runs without any issues, and the build is successful. However, when I try to rebuild the project either through Build > Rebuild Project or by running ./gradlew build, I encounter the same error @vi...@gmail.com is getting.

I have a similar error like yours when rebuild gradle.

'actual object AlarmDatabaseCtor : RoomDatabaseConstructor<AlarmDatabase>' has no corresponding expected declaration

However it works without error at my database.

So it seems the issue is when either running ./gradlew build or via Build -> Rebuild Project in the IDE. This is important information since those actions tend to build 'too many things'. Specially it tries to build common source set in isolation (compileCommonMainKotlinMetadata) which is a grey area in Kotlin right now, due to the expect / actual compilation model it is not possible to publish a 'common-only' library that has expect / actual as consumers can't contribute to those, i.e. you always publish -common along side a platform.

I agree building via those two actions is broken. But are they hindering the rest of your project if iOS (via XCode), JVM Desktop (via ./gradlew composeApp:run) and Android (via Android Studio) launch and work as expected? Or are they preventing you from publishing a library?

If it is still valuable to you to have a successful build via ./gradlew build then we actually just made a fix for this (see https://issuetracker.google.com/359631627) that will be in the next alpha release, the gotcha is that you need to declare the initialize override function in the expect object and then the generated code will also include the actual modifier. You can try this right now with a snapshot version of Room (see https://androidx.dev/). Here is a version of the sample project using the snapshot and with a working ./gradlew build containing the fix in b/359631627): https://github.com/danysantiago/RoomKmpLibraryExample/compare/main...snapshot

In my case, run via Android Studio, run via Xcode, Android CI (./gradlew build) and iOS CI (xcodebuild archive) are all broken with the same error. I've not managed to get a successful build to run with the latest alpha. It's a multi-module CMP project, it's virtually identical to your example project, in terms of Gradle and database initialisation, but with several entity types and DAOs added.

Edit: With snapshot, everything is working 👌🏻

From issue 358393367 on 8/15/2024:

re comment#19 Thank you for your work on this issue! It works in my situation.

Just one question, it seems to me that we can get XXDatabase info through the @Database annotation. I haven't seen the specific code, but I guess XXDatabase_Impl is also generated in this way? Is it possible generate expect object XXDatabaseConstructor : RoomDatabaseConstructor<XXDatabase> automatally without any intervention?

From issue 358913889 on 8/11/2024:

Update! Problems solved by doing things

1. disable room gradle plugin and rewrite ksp { .... } as you mentioned.
2. update kotlin and ksp version to 2.0.10

I think this is just temporary solution, however anyway it works now. I hope next version of room should be fixed ... :) thanks for your help!

Hi, I encountered a similar problem running KMM iOS build (room+ksp) and was able to resolve it by updating the dependencies.

room = "2.7.0-alpha08"
ksp = "2.0.20-1.0.25"

compose-plugin = "1.6.11"
kotlin = "2.0.20"
