// instance.
// joynrConfig.setProperty(MessagingPropertyKeys.BOUNCE_PROXY_URL,
// "http://localhost:8080/bounceproxy/");
// joynrConfig.setProperty(MessagingPropertyKeys.CAPABILITIESDIRECTORYURL,
// "http://localhost:8080/discovery/channels/discoverydirectory_channelid/");
// joynrConfig.setProperty(MessagingPropertyKeys.CHANNELURLDIRECTORYURL,
// "http://localhost:8080/discovery/channels/discoverydirectory_channelid/");
// Each joynr instance has a local domain. It identifies the execution
// device/platform, e.g. the
// vehicle. Normally, providers on that instance are registered for the
// local domain.

// NOTE: When running this application to test the android-location-provider, you must use
// the concrete hostname (and _not_ localhost) in the bounceproxy URL, since this URL
// is registered in the channel URL directory and must be resolvable by the Android
// device.

// 2) Or set them in the static persistence file (default:
// joynr.properties in working dir) at
// runtime. If not available in the working dir, it will be created
// during the first launch
// of the application. Copy the following lines to the custom
// persistence file to set a
// certain joynr server instance.
// NOTE: This application uses a custom static persistence file
// provider-joynr.properties.
// Copy the following lines to the custom persistence file to set a
// certain joynr server
// instance.

// joynr.messaging.channelurldirectoryurl=http://localhost:8080/discovery/channels/discoverydirectory_channelid/
