Problem with Blackberry App without BES

Question

I am developing a Blackberry application that makes quite a few networks using HttpConnections and InputStreams. I tested it in an environment where it has access to BES, but will only dismount it using a wireless network.

Some preliminary tests on the Bold 9000 show that although the phone’s web browser can access the Internet, my application cannot. I understand that BES usually handles most of the networking logic and that Blackberry itself is not very good at it.

I saw some links to add "; interface = wifi" to the URLs I'm trying to connect to, but when I do this, gradually loading a large video file will freeze in a few seconds.

Is there anything else that can be done to make the Blackberry app work wirelessly? Are there any signed classes that I could use to handle this?

Edit

It seems that what is happening is that there is a rare chance that the network just isn't working - General Socket Exception. The problem is that for large files I make a lot of connections, in pieces of 256k, so for large files there is more of an error problem in the end. I'm really not sure how to handle this.

Answer 1

WiFi

public boolean GetWiFiCoverageStatus()  {
    if((WLANInfo.getWLANState() == WLANInfo.WLAN_STATE_CONNECTED) &&
              RadioInfo.areWAFsSupported(RadioInfo.WAF_WLAN)) {
              // this.connectionString += ";interface=wifi";
              return true;
    } else return false;           
}
