Hello! Thank you for filing an issue.

Please include relevant logs or detailed description for faster resolutions.

We really appreciate your contribution!

hey @Mind-Reaper
Whats the Android Gradle Plugin version used in your app?

[Mind-Reaper]

@ygit
8.2.1

[ygit]

@Mind-Reaper Can you try a version in the 7.x.x series, say 7.3.1?

[Mind-Reaper]

Trying that now

[Mind-Reaper]

@ygit That works.
But I get another JVM error now

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':hmssdk_flutter:compileDebugKotlin'.
> Inconsistent JVM-target compatibility detected for tasks 'compileDebugJavaWithJavac' (1.8) and 'compileDebugKotlin' (17).

  Consider using JVM Toolchain: https://kotl.in/gradle/jvm/toolchain

Hi @Mind-Reaper can you try adding below code in the android section android/app/build.gradle

compileOptions {
        sourceCompatibility JavaVersion.VERSION_17
        targetCompatibility JavaVersion.VERSION_17
    }
    kotlinOptions {
        jvmTarget = '17'
 }

[Mind-Reaper]

@ygit

Not working

I tried adding this

kotlin {
    jvmToolchain(17)
}

Still getting the same error related to this package

[Decoder07]

@Mind-Reaper have you set the gradle JDK to 17 in android studio ?

[Mind-Reaper]

Hi @ygit. I tried this too. Still no solution. I noticed some of the sample projects use jvm 1.8.

Do you think it could be the Kotlin version cause I have a more recent one on my project?

[ygit]

hey @Mind-Reaper

Try setting -

1. ext.kotlin_version as 1.9.0 in your build.gradle file's buildscript { ... }
2. Set com.android.tools.build:gradle version as 7.2.2

Refer to the attached screenshot.

Alternatively, can you share your Android project's build.gradle files?

[Mind-Reaper]

@ygit

Just to make things clear. Do you want me to make these changes in my project android directory or in a forked repository of hmssdk ?

hey @Mind-Reaper
Let's get on a call to debug this.
Please book a convenient time here: https://calendly.com/yogesh-singh-100ms/30min

[Mind-Reaper]

@ygit Done, Thanks

[Decoder07]

@Mind-Reaper closing the issue as this is solved.

[rlee1990]

I am having the same issue.
Kotlin version is 2.0.0
com.android.application version is 8.2.2
sourceCompatibility JavaVersion.VERSION_17
targetCompatibility JavaVersion.VERSION_17
jvmTarget = '17'

[Decoder07]

@rlee1990 hms_room_kit no longer uses flutter_foreground_task can you try with latest room kit version

[rlee1990]

@Decoder07 I have it working this can be closed.
