Hello.
I have an issue with launching my app in Release mode.

Looks like I have reached my limit of 65k references, so I have enabled MultiDex for Debug and Release modes. When deploying in Debug mode, my app is working fine and everything OK. But when I launch it Release mode, it crashes at stratup. Here's a Device Log

I tried to add some lines into multidex.keep:

        android/support/multidex/ZipUtil.class
        android/support/multidex/ZipUtil$CentralDirectory.class
        android/support/multidex/MultiDex$V14.class

        md5b3cec4ec1831c6a7ac763d1a35a98e61/RegistrationIntentService.class

No luck.

Another thing I found out is: in obj/Debug/android/big I have classes.dex and classes2.dex, but in obj/Release/android/bin/ I have only classes.dex.

I have also specified Android Build SDK to 25.0.3, and the minimum API level is 19 (to support KitKat 4.4.2). ProGuard specified for Release mode.
In AndroidManifest I specified this:

<application android:name="android.support.multidex.MultiDexApplication">
</application>

So, I have no any ideas what's going on with Android. Looks very weird for Windows dev.
