SQLite auto increment not working

Question

ok this isn't spamming and it's supposed to be simple I don't know why it's not working this is my code:

gamesdatabase = openOrCreateDatabase("GamesDatabase", MODE_PRIVATE, null);
gamesdatabase.execSQL("CREATE TABLE IF NOT EXISTS Games (ID INTEGER PRIMARY KEY, Name
VARACHAR, NPlayers INT(1), NRounds INT(2), WinScore INT(2));");

gamesdatabase.execSQL("INSERT INTO Games 
(ID, Name, NPlayers, NRounds, WinScore ) VALUES ( NULL, 'TAWLA',2,0,0 );");

gamesdatabase.execSQL("INSERT INTO Games 
(ID, Name, NPlayers, NRounds, WinScore ) VALUES ( NULL, 'DOMANA',4,0,0 );");


Cursor c = gamesdatabase.rawQuery("SELECT * FROM Games", null);
c.moveToFirst();
while (c.isAfterLast() == false) {
Log.d("BEZRA", String.valueOf(c.getInt(c.getColumnIndex("ID"))));
c.moveToNext();
}

what's wrong with this ? the log displays 0 for all records

The primary key for SQLite tables is called _id. It is auto incrementing, and you should not be trying to insert values into it.

gamesdatabase = openOrCreateDatabase("GamesDatabase", MODE_PRIVATE, null);
gamesdatabase.execSQL("CREATE TABLE IF NOT EXISTS Games (_id INTEGER PRIMARY KEY, Name
VARACHAR, NPlayers INT(1), NRounds INT(2), WinScore INT(2));");

gamesdatabase.execSQL("INSERT INTO Games 
(Name, NPlayers, NRounds, WinScore ) VALUES ('TAWLA',2,0,0 );");

gamesdatabase.execSQL("INSERT INTO Games 
(Name, NPlayers, NRounds, WinScore ) VALUES ('DOMANA',4,0,0 );");


Cursor c = gamesdatabase.rawQuery("SELECT * FROM Games", null);
c.moveToFirst();
while (c.isAfterLast() == false) {
Log.d("BEZRA", String.valueOf(c.getInt(c.getColumnIndex("_id"))));
c.moveToNext();
}
