Exception “Illegal character in query at index -” in Android

Question

I am trying to send data on server using following link.

**WEBSERVICE LINK:**
http://75.125.237.76/post_reviews.php?data=text1

If I set data filed with single string (ex:data=text1), That time my try block in source code working fine, without any exception.

But When I set data field with multiple string with spaces (ex: data=text1 text2 text3), Then Exception generated ie Illegal character in query.

**EXCEPTION:**
Illegal character in query at index 75: http://75.125.237.76/post_reviews.php?data=text1 text2 text3

My question is Why exception generate when we use multiple strings (like: data=My name is xyz).

If I replace data field with single string that time is working fine.(data=xyz)
