When we save the picture, we'll send a notification telling the system to sdcard it so that the other program will find it immediately.

event bubbling mechanism in the DOM seems a bit like this, for example, after clicking a button, if it doesn't stop bubbling, its Click event will always bubble up to the parent element, and this mechanism can also handle many related problems, such as Example 1: Event centralized management in this series of design pattern sharing meta-mode Example code.

) and the time complexity is O (n). This algorithm is relatively improved compared to algorithm two only when there are n elements, but there are few occurrences of the element.Programme III:The secondary algorithm is improved compared to scenario 2. If the number of digits to be counted is the same as the number N, the time complexity is O (N), and if we find the number, we also use a binary search when we look for its head and tail. Then the situation is not the same at this time! The time com

delete the contents of the collection compared to iterator. In addition to simply traversing and reading out the contents, it is not recommended to use the Foreach loop structure.Look at the information on the Internet when you read a lot about the use of Java iterators articles, see a very detailed article, the address is a Java iterator(go) (iterator and the difference between the For loop) , written well. The main thing we learned when we were learning was the Java API. So always checkAPI, l

Reading Notes Objective c ++ Item 38 is modeled by a combination of "has-a" or "is-implemented-in-terms-of", implemented1. What is composition )? Composition is a relationship between types. This relationship is generated when one type of object contains another type of object. For example: 1 class Address { ... }; // where someone lives 2 3 class PhoneNumber { ... }; 4 class Person { 5 public: 6 ... 7 private: 8 std::string name; //

Angularjs Pull-up loading problem solving methodThere is always a problem in the project: When a keyword is entered in the search field (see Figure 1), the first 7 data of the query is returned after the client receives the request, and then the last 7 data is searched for when a pull-up is loaded. But the actual situation is uncertain, in the server console (see Figure 2) can see Begno has been to 126, that is, the client to the server to request 127 times, this is an intolerable result.Figure

-increment mode, which is then incremented. The pre-increment directly increases on the original value. This is a kind of optimization, as the Zend PHP optimizer does. Keeping this optimization processing in mind is a good idea, because not all command optimizers perform the same optimization and there are a large number of Internet service providers (ISPs) that do not have command optimizers) and server. 35. Object-oriented (OOP) is not required. Object-oriented usually has a high overhead, and

Message Queuing (MessageQueue).A message is removed from the MessageQueue once per loop. The corresponding message handler function is then recalled.Suppose, I mean, if there's a message in the loop body that's not processed (in the message queue), then handler will always be there. The reference count of the handler external class (typically activity) is not 0, so the external class cannot be garbage collected.This is why very many people encounter activity OnDestroy methods that have not been
