I have an Android application which connects to the Internet. I am trapping all the possible scenarios for the connection and notice that when I don't have an Internet connection, an UnknownHostException is thrown. I am a bit confused here since getting an UnknownHostException will mean that the application was able to connect to the Internet but wasn't able to find the given URL.

Am I getting the right Exception? Could you explain why am I getting an UnknownHostException in this?

Also, can you tell the specific Exceptions for these scenarios:

  • When there is no Internet connection.
  • When the URL cannot be found.
  • When the request timed out.
  • When the website is down.
  • When access is denied.

I would also appreciate it if you could give me more scenarios and Exceptions. I have to trap all the possible connections and display the most appropriate message depending on the type of connection Error.
