OpenConnection()

Returns a java.net.URLConnection URLConnection instance that represents a connection to the remote object referred to by the URL.

[Android.Runtime.Register("openConnection", "()Ljava/net/URLConnection;", "")]
public Java.Net.URLConnection? OpenConnection ();
[<Android.Runtime.Register("openConnection", "()Ljava/net/URLConnection;", "")>]
member this.OpenConnection : unit -> Java.Net.URLConnection

Returns

a java.net.URLConnection URLConnection linking to the URL.

Attributes

Exceptions

if an error occurs while opening the connection.

Remarks

Returns a java.net.URLConnection URLConnection instance that represents a connection to the remote object referred to by the URL.

A new instance of java.net.URLConnection URLConnection is created every time when invoking the java.net.URLStreamHandler#openConnection(URL) URLStreamHandler.openConnection(URL) method of the protocol handler for this URL.

It should be noted that a URLConnection instance does not establish the actual network connection on creation. This will happen only when calling java.net.URLConnection#connect() URLConnection.connect().

If for the URL's protocol (such as HTTP or JAR), there exists a public, specialized URLConnection subclass belonging to one of the following packages or one of their subpackages: java.lang, java.io, java.util, java.net, the connection returned will be of that subclass. For example, for HTTP an HttpURLConnection will be returned, and for JAR a JarURLConnection will be returned.
