Question

I have an HTTP connection, opened by

HttpConnection c = (HttpConnection)Connector.open(url);

where url is one of:

• http://foo.bar;deviceside=false
• http://foo.bar;deviceside=false;ConnectionType=mds-public
• http://foo.bar;deviceside=true;ConnectionUID=xxxxxxx
• http://foo.bar;deviceside=true;interface=wifi

Is there any way to cause the request to error out immediately if the connection cannot be established because the device is not connected to a network? As it is, it takes about a minute to timeout in many cases (specifically on the first call to get the information from the network: c.getResponseCode())

Edit: I mean error out. In one case, Wifi, specifically, it will sit around for several minutes if the wifi is not on before timing out, and I want it to stop right away.

I use the RadioInfo class to check if there is a connection and if the radio is turned on before trying to make a connection. Then you can just display a message to the user or turn the radio on (if it’s off) before trying to connect, makes for a much better user experience.

Try using:

if (RadioInfo.getState() == RadioInfo.STATE_OFF)
OR
if (RadioInfo.getSignalLevel() == RadioInfo.LEVEL_NO_COVERAGE)

To check connection status before connecting.
