android - java.lang.ClassNotFoundException : Didn't find class "kotlinx.coroutines.experimental.Deferred"

Question

我在使用带有改造的协程时遇到了这个问题，你能告诉我为什么会出现这个错误

java.lang.ClassNotFoundException:在路径上找不到类“kotlinx.coroutines.experimental.Deferred”:DexPathList[[zip 文件“/data/app/com.coroutines.retrofit.kotlin-1/base.apk"],nativeLibraryDirectories=[/vendor/lib64,/system/lib64]]

当我使用以下依赖项时，

实现 'com.jakewharton.retrofit:retrofit2-kotlin-coroutines-experimental-adapter:1.0.0'

实现 'org.jetbrains.kotlinx:kotlinx-coroutines-core:1.0.1' 实现 'org.jetbrains.kotlinx:kotlinx-coroutines-android:1.0.1'

而 kotlin 版本是: ext.kotlin_version = '1.3.10'

Answer 1

Add this dependency in your build.gradle : (remove experimental dependency for coroutine)

dependencies {
    implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-android:1.0.0'
    implementation 'com.jakewharton.retrofit:retrofit2-kotlin-coroutines-adapter:0.9.2'
}

And add CoroutineCallAdapterFactory() for retrofit

addCallAdapterFactory(CoroutineCallAdapterFactory())
