How to Implement resident threads in AFN and resident threads in AFN The underlying implementation of the nsunloop is actually an endless loop of do-while at the underlying layer.

Note that the Syncexec (runnable) method parameter Runnable object is actually placed in the UI thread, so be careful not to put tread.sleep () in this runnable, otherwise it will cause the interface to be unresponsive.The difference between the Syncexec and Asyncexec methods is that one of the two methods will wait for the runnable to finish before returning, and the Asyncexec method is to return immediately, and the UI thread will execute runnable

After the Tomcat server is started, there are actually 6 threads working, that is, 1 user threads (Thread[main in the image below), and the remaining 5 are daemon threads (daemon thread in the image below), respectively, through bio. First daemon thread (Daemon thread [Containerbackgroundprocessor[standardengine[catalina]] (Running)) is a container spooler thread

In Android development, non-UI threads cannot operate controls in the UI thread, that is, the UI is non-thread-safe. As I said in the previous article: It is non-UI secure, that is, it does not accept modification requests from non-UI threads. When we modify it through another thread (non-main thread or non-original thread, This exception will be thrown: android. view. ViewRoot $ CalledFromWrongThreadExcept

A daemon thread is a thread that provides a generic service in the background while the program is running, such as a garbage collection thread that is a competent guardian, and that thread is not an integral part of the program. Therefore, when all non-daemon threads end, the program terminates and kills all the daemon threads in the process. Conversely, the program will not terminate as long as any non-da

scheduling involves more content (storage space, CPU,I/O resources, process site protection), scheduling overhead, in the concurrent switching process is less efficient. In order to make the scheduling more efficient, the basic unit of independent operation and Dispatch is proposed which is lighter than the process.Characteristics:1, the thread is lighter than the process.2, the thread can run independently, independent scheduling, with resources (generally CPU resources, program counters, etc.

Join () Waits for the child thread to execute, the mainline friend continues to execute, and then exits the program when all threads have finished executing.When the thread is turned into a daemon thread, it exits the program as soon as it executes, regardless of whether the child thread is finished or not.The main thread cannot be set as a daemon.#主线程启动子线程之后, the two are parallel and independent of each other.

When we create a sub-thread, is it to make it like a runaway horse, a stroll, or like a good obedient child, from time to time to teach it? To solve this problem, this article introduces the combination and separation of threads, the structure is divided into three parts, the first part gives the code example, the second part explains the code, the third part is the running result.A code exampleTwo code explanationThe function is a child function of t

We all know that traditional thread synchronization can be implemented through synchronous code blocks or synchronous methods. The synchronization monitor is involved here. If you do not know about the synchronization monitor to get the thread-related knowledge is not understanding, you can view the blog http://blog.csdn.net/johnny901114/article/details/7536951 To ensure synchronization between threads, the monitor object is the same object for Synchr
