But over the last couple of years, and in this one in particular, we are starting to see companies shift from what is the largest screen size, the smallest form factor or the shiniest object and more into what all of these devices do that is practical in a consumer's life. 出自-2016...
Device emulators are testing environments that simulate specific devices. Emulators run on the developer's PC, so that testing can be performed without the device. Events An event is a message sent by an object to signal the occurrence of an action. The action could be caused by user inte...
If you are talking to another device, you can use the version of client.Connect that takes an IP Address instead of a host name. Of course, then you need some way to get that IP Address from the remote machine. Getting your own addresses is easy, though. For example, let's say you...
