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

Question

My app was working fine until I added kotlin coroutines as instructed here . When I click a floating button to open another activity from this lib I get this error. With coroutines removed app works fine.

I have already tried a number of solutions such as:

1. Disabling instant run.
2. Clean and Rebuild
3. Adding minifyEnabled false to debug buildType.
4. Adding multiDex

But none worked.

 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'
....
 }

Answer 1

The experimental coroutines are used in an old version of the Fotoapparat that PixImagePicker depends on. See here

Though Fotoapparat has updated so it's not using these anymore, and PixImagePicker seems to be using the latest version of Fotoapparat too.

Maybe raise issues with them on Github.
