the generated standalone apk can't support 4.x device if Apk contains java8 lambda expressions

[staney7]

I use bundletool to generate a standalone APK for 4.x device , but it can't work. I find that when I use lambda expression in my application code , the appliaction will crash because of NoClassDefFoundError.

My APK has a dynamic module .There is three dex file in main module and one dex in a dynamic module. And in this dynamic module , I set fusing = true .

This might have been fixed with a more recent version of D8. We have plans to upgrade the version soon, but you could try to update the dependency locally in your build gradle file by setting compile "com.android.tools:r8:1.4.93"

I try to set comile "com.android.tools:r8:1.4.93" in my app build gradle file, but it doesn't work for me, the application will crash too. My Android studio version is 3.4.2 , gradle version is 5.1.1 and android tool version is 3.4.2. Is there any other way to fix it?

This is my Stacktrace:
