By using different settings in copy bundle resources, we can make different products contain different resources, including the main icons of the program, etc, instead of including the resources listed in the xcode project.
This is not all the content specified by a target. Each target can use an independent and different info. plist file.

Recently, after re-scanning all currently active cne sep, it is concluded that only five of the nine identified CNE devices can be used for intrusion. Four other implants have been removed. Four of the five udids return the recent UDID association found in passive collection. These are described in detail in the iPhone target list. [F]
After analyzing all tao sep, 116 udids are identified. 15 of these udids are associated with the iPhone user proxy
initializes a new tracking child each time a new target is detected. Although this kind of method can take advantage of the more mature single-target tracking algorithm, but it does not take into account the impact of each goal, the general improvement method is to introduce the online learning mechanism, the other targets as negative samples to learn, so as to avoid the two

We usually obtain resources through the findviewbyid method. For example, we often use this statement in the oncreate method:
Btnchecked = (imageview) findviewbyid (R. Id.Imgcheck);
Findviewbyid is a convenient way to obtain various view objects in layout, such as buttons, labels, listview, and imageview. As the name suggests, it requires an int parameter: Resource ID.
Resource ID is very useful. Android a

_blank means that browsers always load target= "_blank" documents in a newly opened, unnamed window. Everyone here may not understand what "unnamed" means. In fact, Target is able to assign an ID to a newly opened window, for example: target
