After upgrading from AGP 3.4 to 3.5 our app started crashing on devices running Android 5.0 and 5.1.

This is the exception:

```
Caused by: java.lang.ClassNotFoundException: Didn't find class "my.domain.path.MyClassName" on path: DexPathList[[zip file "/data/app/my.domain.myapp-1/base.apk"],nativeLibraryDirectories=[/vendor/lib64, /system/lib64]]
at dalvik.system.BaseDexClassLoader.findClass(BaseDexClassLoader.java:56)
at java.lang.ClassLoader.loadClass(ClassLoader.java:511)
at java.lang.ClassLoader.loadClass(ClassLoader.java:469)
```

This happens both on debug builds (isMinifyEnabled = false) and release builds (isMinifyEnabled = true).
Rolling back to AGP 3.4 fixes the issue.

I'd be glad to give you any more info you'd need or perform any other task that might help debugging.

Thanks,
Bye,
Marco

Ivan and Esteban, can you help triage this. Looks like a build system change / apply changes causing >100 dex files in the debug variant?

This is most likely a Gradle bug, I am looking into it.

Can you please check how many DEX files are in:
- app/build/intermediates/dex/debug/mergeExtDexDebug/out
- app/build/intermediates/dex/debug/mergeLibDexDebug/out
- app/build/intermediates/dex/debug/mergeProjectDexDebug/out

? Also, which other plugins do you apply in your application module?

ma...@gmail.com <ma...@gmail.com> #8Jun 14, 2019 10:26AM

- app/build/intermediates/dex/debug/mergeExtDexDebug/out
3 dex files

- app/build/intermediates/dex/debug/mergeLibDexDebug/out
671 dex files

- app/build/intermediates/dex/debug/mergeProjectDexDebug/out
1 dex file

This is the current Gradle plugin block in the app module:

```
plugins {
id("com.android.application")
kotlin("android")
kotlin("android.extensions")
kotlin("kapt")
id("com.google.firebase.firebase-perf")
id("io.fabric")
id("com.github.triplet.play")
id("io.gitlab.arturbosch.detekt")
id("com.github.ben-manes.versions")
}
```

After reviewing 132840182 I can confirm removing "com.google.firebase.firebase-perf" from the plugins block solves the issue.

Thanks!
