for now we only see it on one single device and it is Lenovo Lenovo K3 Note on Android 7.

@stan-ko Just to be clear this happened only once for one of the users of your app and it does not occur on your test devices?

[stan-ko]

Not only once but seems like for only one device. It does not occur on our test devices.

@stan-ko This kind of things are really tough to resolve (if it happens only on a single device).

java.lang.ClassNotFoundException: Didn't find class ""com.android.internal.util.Predicate"" on path: DexPathList[[zip file ""/data/app/ua.ndaapp-1/base.apk""],nativeLibraryDirectories=[/data/app/ua.ndaapp-1/lib/arm64, /system/fake-libs64, /data/app/ua.ndaapp-1/base.apk!/lib/arm64-v8a, /system/lib64, /vendor/lib64]]

This makes me think like that the problem is not really on our SDK's side. Are you using MultiDex by any chance?
