Answer 1

GROUP ein reserviertes Schlüsselwort ist. Verwenden Sie einen anderen Namen.

Answer 2

Sie sollten exakte Leerzeichen im DATABASE_CREATE-Befehl verwenden.

Beispiel:

private static final String DATABASE_CREATE = "create table " + TABLE_COMMENTS + "(" + COLUMN_ID + " INTEGER PRIMARY KEY AUTOINCREMENT, " + COLUMN_COMMENT + " TEXT NOT NULL" + ");";
