Blank screen with multidex in android 4.0.3

Question

I have an application which supports android version from 4.0.3 up to 6.0 and it has reached the total amount of allowed methods in application and it forced me enabling multidex feature.

The application has support for swipe to dismiss feature and I was using a component named EnhancedListView. This library was causing several issues and I replaced it with RecyclerView.

After that device (Dolphing black - android 4.0.3) stopped working. When I run application I get a white screen followed by ANR and a log message informing that VM 1.6 does not support multidex.

I confirmed in android shell that this device is running under VM 1.6 as shown in image below:

But that information is contradictory since before replacing EnhancedListView by RecyclerView multidex was working.

Below follows the logcat displayed after running application

PS: Replacing EnhancedListView by RecyclerView was just a tip but the main focus here is multidex support.

Can anybody help me with that?
