No implementation found for long app.rive.runtime.kotlin.core.File.import(byte[], int)

[leolr02]

gradle version: 6.8.3

Rive version: app.rive:rive-android:5.0.0

kotlin gradle version: 1.8.0

Kotlin version: 1.7.1

I trying to load a Rive file animation from a raw folder via xml :

<app.rive.runtime.kotlin.RiveAnimationView
    android:id="@+id/loginBackground"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:riveResource="@raw/background"
    app:riveAutoPlay="true"
    app:riveFit="CONTAIN"
    app:riveLoop="LOOP"
    />

And init Rive in the Activity in onCreate function:
Rive.init(this)

Tha'ts my provider on Manifest file:

    <provider
        android:name="androidx.startup.InitializationProvider"
        android:authorities="${applicationId}.androidx-startup"
        android:exported="false"
        tools:node="merge">
        <meta-data
            android:name="app.rive.runtime.kotlin.RiveInitializer"
            android:value="androidx.startup" />
    </provider>

But when the app run, throws me this error:

No implementation found for long app.rive.runtime.kotlin.core.File.import(byte[], int) (tried Java_app_rive_runtime_kotlin_core_File_import and Java_app_rive_runtime_kotlin_core_File_import___3BI)

Seeing similar issue: Fatal Exception: java.lang.UnsatisfiedLinkError: No implementation found for long app.rive.runtime.kotlin.renderers.Renderer.constructor(boolean, int) (tried Java_app_rive_runtime_kotlin_renderers_Renderer_constructor and Java_app_rive_runtime_kotlin_renderers_Renderer_constructor__ZI)

version rive:app.rive:rive-android:8.2.2

[leolr02]

I found the solution, I change the following dependencies:

gradle version to 7.3.3

build:gradle(app)

buildToolsVersion "30.0.3"
compileOptions {
sourceCompatibility JavaVersion.VERSION_11
targetCompatibility JavaVersion.VERSION_11
}

kotlinOptions {
    jvmTarget = "11"
}

rive to 'app.rive:rive-android:4.0.0'
initializer to "androidx.startup:startup-runtime:1.1.1"
kotlin stdlib to "org.jetbrains.kotlin:kotlin-stdlib:1.8.0"

build.gradle(AppName)

dependencies {
classpath 'com.android.tools.build:gradle:7.2.2'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.8.0"
}

I hope that is useful for you

If you want to initialize Rive in a specific context, you can also call:

// YourRiveActivity.kt
class YourRiveActivity : AppCompatActivity() {
  override fun onCreate(savedInstanceState: Bundle?) {
    Rive.init(this)
    …
  }
}

I'm going to close this for now as it seems resolved.
I also recommend upgrading to the latest rive-android, currently we're at 8.2.3
