what is missing in my sqlite syntax for foreign key?

I created two sqlite tables on android

phone table with primary key "id"

CREATE TABLE BLOCKED_PHONES_TABLE ( id INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL DEFAULT 1, KEY_PHONE TEXT UNIQUE,KEY_IS_BLOCKED BIT )

comment table with foreign key "id"

CREATE TABLE COMMENTS_TABLE ( id INTEGER, KEY_COMMENT_TEXT TEXT, FOREIGN KEY(id) REFERENCES BLOCKED_PHONES_TABLE(id))

why does the comment table don't refer id as a foreign key?

otherwise it won't have ids that are missing in the phone table.

how can I know my sqlite version?
