How to check if data is inserted in Room Database

Question

I am using Room Database from the new Architecture components in my project. I am adding some data through dao, but when trying to retrieve it I am not getting it. Can you pleas

Answer 1

The problem was in the thread. Room doesn't allow you to run database queries in main thread. The call to insert method was inside of a try-catch block, and I was ignoring the exception. I fixed it, and here's how it reads right now.

doAsync {
                        val addedID = appContext.db.rallyDAO().addVehicleListItem(vehicle)
                        Logger.d("vehicle_lsit_item","Inserted ID $addedID")
        }

Also, I reviewed the documentation, the insert method may return a Long (or List of Long in case of List passed to insert). I also changed the signature of insert, and here is the modified code

@Insert(onConflict = OnConflictStrategy.REPLACE)
fun addVehicleListItem(vehicleListItem:VehicleListItem):Long

P.S. I am using anko for doAsync
