Blackberry push notification implementation
问题 How does one implement a push notification for a blackberry app? I heard that in order to do so I need to purchase a Blackberry Enterprise Server which costs me 1400 per year. Is this true? Where is a good starting point in implementing push notifications? I am experienced with iPhone push development, but cannot find the equivalent for blackberries. 回答1: Earlier this year Blackberry launched a push service that does not require a BES, similar to Apple's offering. The have a Java SDK for it.
