SQL Statement throws exception with autoincrement

I am trying to create a table in an sqlite database with the following statement:

CREATE TABLE contacts (
_id INT NOT NULL AUTO_INCREMENT,
name VARCHAR(20) NOT NULL ,
PRIMARY KEY (_id)
);

It throws the following exception:

java.sql.SQLException: near "AUTO_INCREMENT": syntax error
at org.sqlite.core.NativeDB.throwex(NativeDB.java:397)
at org.sqlite.core.NativeDB._exec(Native Method)

I am not able to find a syntax error. If i omit the auto_increment, everything works fine.

Any hints?
