seems found what caused that error - it was happening due multidex bot properly enabled - so be aware :slight_smile:

#3

How did you enable multidex?

#4

Hi, I’m used this tutorial for gradle:

https://developer.android.com/studio/build/multidex.html

Our app missed that part in Android manifest due it crashed on Android 4.x devices:

#5

Good to know, i haven’t used this feature. So need to disable or enable it to fix the issue?

#6

Multidex with SDKBOX should be enabled as there is to many methods, but in this case you
need also to add to android manifest tag android:name=“android.support.multidex.MultiDexApplication” otherwise on older devices it will crash.

#7

What devices did you test on? I will try to reproduce it, then i can make sure that the issue is fixed.

We have samsung s3 with android 4.3
