开始4.1.2时Android / Kotlin崩溃-ExceptionInInitializerError

Question

I'm using Kotlin within my app; however, when testing on lower API devices, it crashes on start.

Even attaching a debugger to the onCreate for the Splash Activity , it still crashes before any breakpoint.

I was able to get a callstack once, but I can't get any other callstacks.

Caused by: java.lang.NoClassDefFoundError: kotlin.jvm.internal.Intrinsics

Which points at: val intentFilter = IntentFilter(NotificationType.INVITE_RECEIVED)

which is an extension function that allows me pass my NotificationType enum into the IntentFilter.

enum class NotificationType(private val str: String) {

    // Orders
    ORDER_HOST_PAID("ORDER_HOST_PAID"),
    ...
}

I don't know what would cause this issue, as I use Kotlin in another app without this issue. Could it a gradle issue?

I'm using ext.kotlin_version = '1.2.0-beta-88'

It was because while I had multiDexEnabled true , I was not extending MultiDexApplication . That is only required if you're supporting API 20 or lower.

Adding the library to your dependencies.

android {
    defaultConfig {
        ...
        minSdkVersion 15 
        targetSdkVersion 26
        multiDexEnabled true
    }
    ...
}

dependencies {
  compile 'com.android.support:multidex:1.0.1'
}

And extending MultiDexApplication :

public class MyApplication extends MultiDexApplication

I had the same error and I solved it with MultiDex, like described on this link : https://developer.android.com/studio/build/multidex.html
