Android SQLite database not populating

I am trying to create an SQLite database. The create method: 

private static class DatabaseHelper extends SQLiteOpenHelper {

    @Override
    public void onCreate(SQLiteDatabase db) {

        db.execSQL(CREATE_BASE_TABLE);
    }

}

(the constructor and the upgrade function are implemented in that private class as well)

is calling the SQL string:

static final String CREATE_BASE_TABLE ="create table if not exists tableData ("
        + "id INTEGER PRIMARY KEY,"
        + "name TEXT,"
        + "image TEXT,"
        + "var1 TEXT,"
        + "var2 TEXT,"
        + ");";

but the execSQL returns success=false , as revealed by the debugger and breakpoints.

In File Explorer I see that data is created in the databases folder. I open that file on my local machine and only see a table called android_metadata not tableData and my fields are nowhere to be seen!

How do I fix it to make my method properly populate my table? Is there a syntax issue with my query?

It's very subtle but the error is in your create table command. This line should not have a comma:

+ "var2 TEXT,"

Instead, it should just be:

+ "var2 TEXT"

since it is the last column you are defining.
