enterLastName = (EditText) findViewById(R.id.enterLastName);
enterNumber = (EditText) findViewById(R.id.enterNumber);


}


public void addContact(View view)
{
String first = enterFirstName.getText().toString();
  String last = enterLastName.getText().toString();
 int num = Integer.parseInt(enterNumber.getText().toString());
SqLiteAdapter adapter = new SqLiteAdapter(this);
 long id = adapter.insert(first, last, num);
}

and the error "no such table contacts (code1) while compiling: insert into contacts etc.."

i just dove into database storage for my app (oh lucky me) i've been getting this error with all the tutorials i've followed through on, and now even in my own code. researching this topic it seemed that i was trying to write into the database before it was created, so i set up Toasts to track the flow and it it's progression didn't seem like i was writing to it before it was created, but idk i'm a beginner. so why exactly do you guys think i'm getting this error? i apologize in advance for the sloppy editing, and thank you in advance for any help so i can start writing better code =D!
