title: Parcel Unmarshalling unknown type code
body: <p>We are getting this error in the Crash reports logged by play store. Cant replicate this in all our testing. Does anyone else have the same problem or solution ?
  Thing is, we dont even know what to do to replicate this bug.</p>
  
  <p>All Parcelable objects have <strong>CREATOR, writeToParcel() and contructor</strong> defined. All Lists and complex types are initialised and null checked.</p>
