giving EventBus error

[demo-Ashif]

Could not dispatch event: class com.google.android.gms.vision.barcode.Barcode to subscribing class class com.edwardvanraak.materialbarcodescanner.MaterialBarcodeScanner
java.lang.IllegalStateException: Can not perform this action after onSaveInstanceState

Always giving this error after onResult when am wanting to show DialogFragment.
Testing in Nexus 6 device.

If you are using proguard, you need to keep the event classes that are only referenced through annotations. See issue #35
