The function that is throwing it
fun getGameTime(gameId: Long): String{
val db = this.readableDatabase
val cursor = db.rawQuery("SELECT ${gameTable.timestamp} FROM ${gameTable.table} WHERE ${gameTable.id} = ${gameId}", null)
var result = ""
if(cursor.moveToNext()){
result = cursor.getString(cursor.getColumnIndex(gameTable.timestamp))
}
db.close()
return result
}
As I google CursorWindowAllocationException almost every result is something related to not closing the cursor, and out of memory causing the moveToNext() to throw the exception.
How ever, in the stacktrace that I got there is nothing about out of memory and I believe that my cursor would be closed since the readableDatabase database that it lived on is closed?
The devices where the error occured
Basically a modern phone with 2GB ram. It happened once in the past 60 days, but I have seen it few months back.
The app is approximately run on 40 devices each day, so that is 1 crash in 2400 runs - not much, but I would like to know why this is happening.
