Hi,

I have firebase database Sales and I want to get the results of time range. Starting at 13:00:00 (1577278800000 as milliseconds) and end at 13:30:00 ( 1577280600000 as milliseconds )

Sales  
-Lws9QiOnoc\_lc0ECoYn  
-total:  
-time: 1577278800000

> val rootRef = FirebaseDatabase.getInstance().reference

```
    val query = rootRef.child("Sales").orderByChild("time").startAt(1577295000000).endAt(1577195256918)
 

    //println("query1" +query1)
    val valueEventListener = object : ValueEventListener {
        override fun onDataChange(p0: DataSnapshot) {
            if (p0.exists()) {
                for(ds in p0.children) {
                    val timeList = arrayListOf<Long>()
                    val time = ds.child("time").getValue(Long::class.java)!!
                    timeList.add(time)
      
                }
            }
        }

        override fun onCancelled(databaseError: DatabaseError) {
            Log.d(TAG, databaseError.getMessage()) //Don't ignore errors!
        }
    }
  
    query.addListenerForSingleValueEvent(valueEventListener)

```

The thing is it is giving error when I try to run.  
here is the error :

> None of the following functions can be called with the arguments supplied:  
> @NonNull @PublicApi public open fun startAt(p0: Boolean): Query defined in com.google.firebase.database.Query  
> @NonNull @PublicApi public open fun startAt(p0: Double): Query defined in com.google.firebase.database.Query  
> @NonNull @PublicApi public open fun startAt(@Nullable p0: String?): Query defined in com.google.firebase.database.Query

startAt() taking Long as paramater and I have no idea why it is giving me this error.  
Can anyone please help me here.

You are passing in an Int. Put an “L” on the end of the number literal to make it a Long.

1577295000000 is Long value, not an Integer
