Android/Kotlin: Error: "Expecting a top level declaration > Task :app:buildInfoGeneratorDebug"

Question

I try to write a class to manage a SQLite DB, but I have the error message "Expecting a top level declaration > Task :app:buildInfoGeneratorDebug".

   package com.xexxxwxxxxs.GMP

    import android.database.sqlite.SQLiteDatabase
    import android.database.sqlite.SQLiteOpenHelper
    import android.content.Context
    import android.content.ContentValues

    class DBHandler(context: Context, name: String?, factory: SQLiteDatabase.CursorFactory?, version: Int) : SQLiteOpenHelper(context, DATABASE_NAME, factory, DATABASE_VERSION)
    {
        override fun onCreate(db: SQLiteDatabase)
        {

        }

        override fun onUpgrade(db: SQLiteDatabase, oldVersion: Int, newVersion: Int)
        {

        }

        companion object
        {
            private val DATABASE_VERSION = 1
            private val DATABASE_NAME = "GMP.db"
        }
    } 

Do you have any ideas?

Thanks in advance

Answer 1

I just delete the last curly brace and write it again. It's working :)

You just killed me :D It works. Incredible... It seems that there is a invisble character at the end. – Vertumnus

In my case there was an extra closing braces – Bangweulu

Just when I though that there is no place for black magic in the coding. hehe. Thanks. – Overshine

I found the same error because I used a - dash in fun name... – Antenna

Answer 2

The same happened to me, you just need to remove an auto-generated extra curly bracket at the end, then it works.

I had a slightly fancier version: I had to delete the last three brackets and put them back in again. – Criseyde

Answer 3

I had recently changed my package name (e.g., com.example.myappname) and found that the MainActivity.kt package name on Line 1 was not updated to the new name -- which caused this error.

Answer 4

This error can show up if you have defined any object outside of class declaration

example :
class someActivity extands something{ } private someMethod(){}

to solve this just move it inside

`class someActivity extands something{

private someMethod(){} }`

Answer 5

If, like me, you are working in code (VSCode), you should remove the call to main() at the end of the file. For example

fun main(){
println("This will fail")
}
main()

For the above, we shall get the following error:

your_file.kt:50:6: error: expecting a top level declaration main()

Removing the call to main() fixes the issue.

Hi, can you explain why should we put function invoked(i.e println()) into main ? – Miniature

Only in vscode. It automatically runs it. – Pearliepearline
