Use of composite keys with an AUTOINCREMENT column in SQLite database

I've created a table which has a column "_id" which is an INTEGER type with AUTOINCREMENT. Now I know that a column which is on AUTOINCREMENT has to be a PRIMARY KEY , which is the syntax if I'm not wrong. But I want Composite keys so I don't declare the "_id" as (_id INTEGER PRIMARY KEY AUTOINCREMENT)with the PRIMARY KEY defintion in the column definition but declare it as (_id INTEGER AUTOINCREMENT, username TEXT UNIQUE, password TEXT, name TEXT, phonenumber TEXT, address TEXT, fine INTEGER, bookid INTEGER, PRIMARY KEY (_id, username, password))

But it gives a runtime error. Is it the case that when we have an AUTOINCREMENT field it's compulsory to declare the PRIMARY KEY in the column definition itself?

Here's the error

07-18 12:47:22.916: E/AndroidRuntime(3423): Caused by: android.database.sqlite.SQLiteException: near "AUTOINCREMENT": syntax error (code 1): , while compiling: CREATE TABLE userdetails (_id INTEGER AUTOINCREMENT, username TEXT UNIQUE, password TEXT, name TEXT, phonenumber TEXT, address TEXT, fine INTEGER, bookid INTEGER, PRIMARY KEY (_id, username, password));
