在按照here的说明添加kotlin协程之前，我的应用程序运行良好。当我单击一个浮动按钮从该lib中打开另一个活动时，出现此错误。删除协程后，应用程序运行正常。
我已经尝试了多种解决方案，例如：
但是没有一个。
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'
....
}
踪迹

实验协程用于Fotoapparat所依赖的PixImagePicker的旧版本中。参见here
尽管Fotoapparat已更新，所以不再使用它们，并且PixImagePicker似乎也在使用最新版本的Fotoapparat。
也许在Github上引起他们的问题。
