java.lang.NoClassDefFoundError: Failed resolution of: Lkotlinx/coroutines/experimental/CompletableDeferredKt

Question

我的应用程序运行良好，直到我按照说明添加 kotlin 协程 here . When I click a floating button to open another activity from this lib 我收到此错误。删除协程后应用程序工作正常。

我已经尝试了很多解决方案，例如：

禁用即时运行。
清理并重建
将 minifyEnabled false 添加到调试 buildType。
添加 multiDex

但是 none 有效。

 android {
compileSdkVersion 28
defaultConfig {
    ...
    minSdkVersion 17
    targetSdkVersion 28
    multiDexEnabled true
    ...
   }
 }

 dependencies {
implementation "org.jetbrains.kotlinx:kotlinx-coroutines-core:1.1.1"
implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-android:1.1.1'
implementation "org.jetbrains.anko:anko:$anko_version"
implementation "org.jetbrains.anko:anko-design:$anko_version"

implementation 'com.fxn769:pix:1.2.5'
implementation 'com.android.support:multidex:1.0.3'
....
 }

痕迹

PixImagePicker 所依赖的 Fotoapparat 的旧版本中使用了实验协程。参见 here

虽然 Fotoapparat 已经更新，所以它不再使用这些，而且 PixImagePicker 似乎也在使用最新版本的 Fotoapparat。

也许可以在 Github 上向他们提出问题。
