There is no error when I use kotlin versions: 1.6.21, but issue/error starts appearing when kotlin version is 1.7.0

Thanks for the report I was able to reproduce the issue and indeed it occurs when using Kotlin 1.7.0. Sadly I don't have a workaround yet, but will investigate further.

and just to clarify, we see the issue when using Room 2.4.2, but not with Room 2.5.0-alpha02.

Hey all, looks like the issue is related to a change in Kotlin's @Metadata annotation and the way Room reads it, Room 2.4.2 is using an older version of the kotlinx-metadata-jvm library which does not support reading Kotlin 1.7 information, where as in Room 2.5.0 we updated the library.

To workaround this issue please force upgrade the dependency by adding it to your annotation processor path, i.e. add kapt "org.jetbrains.kotlinx:kotlinx-metadata-jvm:0.5.0" if you are using Room 2.4.x.

Meanwhile, I'll work on releasing a Room 2.4.3 that is compatible with Kotlin 1.7 since Room 2.5.x is still in development.

Thanks! Do you think 2.4.3 is something that will be released in the next couple weeks? Trying to decide if I want to use the workaround or just wait until it is released.

We have an upcoming androidx release in July 20, I am trying to aim for that.

I also wanted to mention that if you migrate to using KSP instead of KAPT you won't run into this issue, as long as you use the KSP version that is compatible with Kotlin 1.7.0 which is 1.7.0-1.0.6.

Maybe reopen this.

@Query("SELECT * FROM ${SetupData.TABLE_NAME}")
suspend fun selectAll(): Cursor

[ksp] SetupDataDao.kt:24: Not sure how to convert a Cursor to this method's return type (android.database.Cursor).

Duh!

• Room 2.5.2
• Kotlin 1.9
• KSP 1.9.0-1.0.11

The diagnosis is the same, Room needs to update its kotlinx-metadata-jvm dependency to be able to read Kotlin 1.9+ metadata. An upcoming patch release (Room 2.5.3) will have the dep updated.

Alternative if you use the KSP version of Room, this shouldn't be an issue.

Issue is still present if you want to return Cursor

Room 2.7.0-alpha12 kotlinVersion = "2.1.0" kspVersion = "2.1.0-1.0.29"

Sample: @Query("SELECT * FROM ${SetupData.TABLE_NAME}") suspend fun selectAll(): Cursor [ksp] Not sure how to convert a Cursor to this method's return type (android.database.Cursor).

New CL merged. Will release a new version ASAP.

The fix is available in the next canary and stable release in June.

RE#36 To clarify, the bug is still reproducible for API 29 and API 30. Other APIs are working fine. We have an internal bug for tracking the API specific time update issue.

The new fix is merged

sivhuop@ Hi, the fix is not merge in (33.1.4-9936625). Would it be possible for you to upgrade your emulator the latest canary version or at least 33.3.14? Here is the link to the archived emualtor downloads.

RE#42 Thanks for the feedback on the emulator. To help us troubleshoot this issue further, we will need more information. Please share detailed reproduction steps as much as possible of the following information:

1, Run the emulator from command line with “$ANDROID_SDK_ROOT/emulator/emulator -avd <NameOfAVD> -verbose -wipe-data” and send the logs from terminal

2, Run adb bugreport and send the zip file.

I confirm 34.1.9 has no this issue anymore
