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

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)

#*#* on the dial-up interface to open the Developer Tools feature (Input *#* #6960 #*#* off), click "Settings", "Accessibility" and "Developer Tools" , find "Show layout boundaries" in the drawing bar and open. So the control layout of all the apps is at a glance, WebView as a control, there is only one bounding box, so through this, it is easier to distinguish whether an interface is implemented WebView or native layout control, Of course, do not rule out the use of a bunch of webview to spell

, the first way of logic clear, very flexible, but to a certain extent increased memory and resource consumption. The second way is that the layout files are duplicated (although the same parts can be included, but logically there are duplicates), including essentially repetitive code that is handled logically. This approach is generally recommended for larger, different item layouts.Sometimes the combination of demand, can be based on the first way, combined with viewstub "placeholder" can be b
