UNIQUE constraint failed , SQLite, Java

I have a database with methods addPub and GetAllPubs:

However when ever I try to run an add function like:

Database db = new Database(this);
    db.addPub( new Pub(1,"The Old Queen's Head","53.3809646","-1.4631316","10:00","23:00","p","0","1","1","0","0","1","0","1","0","0","07983559073"));

I get this error:

E/SQLiteDatabase﹕ Error inserting OUTSIDE=1 PUB=p PHONE=07983559073 BEER=1 COCKTAIL=0 LNG=-1.4631316 NAME=The Old Queen's Head ID=1 CLOSE=23:00 LAT=53.3809646 SPORT=0 DART=0 QUIZ=0 OPEN=10:00 PAY=0 MUSIC=1 FOOD=1 POOL=0

And I cannot figure out what the cause is and how to edit my code.
