I recently created a file gdb with relationships and pushed it into AGO. I have had success using the map in IOS and Android and been able to use all of the relationship functionality in the field. However when I try to take it offline on my android I get the following message
"The map '...' failed to download with the message: Unable to create replica. Please check your parameters., Error in creating runtime geodatabase."
It works fine on any IOS and I was successfully able to take other maps offline on my android that had simple feature services. I know there have been numerous posts on this topic but I still cannot seem to find the answer. I am on 10.3 in both collector and ArcGIS.
