Thanks.
I created foreign key, but when I try to insert values using m application
it throws
*android.database.sqlite.SQLiteConstraintException: error code*
* 19: constraint failed.*
*
*
But if I insert values manually usiing console, then values are inserted
properly. Why is it so?

Most likely, it means you didn't specify a value for the foreign key
when inserting into the child table (ref_id_value in the snippet below).

I assigned pre-defined value for foregin key. The thing that happens is
that on first time use of that key, an entry is created in database. But if
I use that value for second time then value is not updated in database
My database table strings are as follows
private static final String

Brad,
Not sure if I understand
What happens is that it doesn't allow multiple entries for that pro_id. I'm
not able to understand why that is happening.

Your table definition looks pretty reasonable to me (perhaps I'm missing
something).
Are you sure it's really that column? You have a lot of NOT NULL
constraints in table event, maybe it's one of the other ones?
You previously wrote that inserting values by hand (sqlite3 command
line tool?)

SQLite has foreign key support starting with version 3.6.19.
http://www.sqlite.org/foreignkeys.html
Some versions of Android have SQLite versions earlier than that -
someone posted a breakdown recently, check the list archives.
For earlier versions, it works pretty well to do something like:
