This kind of knowledge point, everyone in the development process can not pay attention to, this will lead to a problem, that is, the development of the application is not a problem, but in the interview as long as the interviewer to ask a little detai

provided to the entire application, so you can understand why the static function is used to create it. Examples are as follows:Androidhttpclient httpClient = androidhttpclient.newinstance("my-http-agent-string");The parameter that is taken is the HTTP request message header user-agent. For example, in the last study we showed the contents of the User-agent message header by grabbing a packet:dalvik/1.6.0 (Linux; u; Android 4.2.2; SDK build/jb_mr1.1)

This example has a static method}catch (Exception e) {Strictmode not supported on this device, puntLOG.
