Question

db = openOrCreateDatabase("tompomodoros.db", Context.MODE_PRIVATE, null);
db.execSQL("CREATE TABLE mytable (_id INTEGER PRIMARY KEY AUTOINCREMENT, mydate VARCHAR, mydata SMALLINT)");

I use above code to create db and its table “mytable”. But for the second time I run it, the phone goes to dead. I guess that is because I create the table again but it already exists there.
So my question is how to create the table for the first time and open it for the rest times?

Answer 1

Try with if not exists:

db.execSQL("CREATE TABLE if not exists mytable (_id INTEGER PRIMARY KEY AUTOINCREMENT, mydate VARCHAR, mydata SMALLINT)");

and then us it as usual.
