首先,我们需要创建一个HandlerThread实例,并启动它。 HandlerThreadhandlerThread=newHandlerThread("HandlerThreadExample");handlerThread.start(); 1. 2. 2. 创建 Handler 接下来,我们创建一个Handler实例,它将与我们刚才创建的HandlerThread关联。 Handlerhandler=newHandler(handlerThread.getLooper()){@Overridepublicvoidhan...
下面以HandlerThread为例,讲一下Handler与子线程的关联过程,下面是HandlerThread的run方法。 1publicvoidrun() {2Looper.prepare();3...4Looper.loop();5} Looper.prepare中完成了Looper,MessageQueue的创建。MessageQueue是Looper的成员变量,所以一个Looper对应一个MessageQueue。 1privatestaticvoidprepare(booleanquitAllow...
After my project was packaged with Xcode15, the following crash occurred, which had not occurred before. After checking for a long time, the cause was not found, because similar problems did not occur when Xcode14 was used to package, so I think it is the problem caused by Xcode15 packag...
Attestation should not run on your UI thread, you can use HandlerThread to deal with this situation. JWS Header: A string representing a JSON object that describes the digital signature or MAC operation applied to create the JWS Signature value. JWS Payload: The bytes to be secured -- aka,...

HandlerThread介绍 google封装了一个HandlerThread类,进一步简化自定义线程消息处理,就不用那么麻烦的处理Looper的创建和启动了。HandlerThread的使用类似下面这样: classMyHandlerextendsHandler{//这种方式,使用的创建Handler所在线程的LooperpublicMyHandler(){}//为了与自定义的线程关联,需要指定对应线程的looper。publicMyHand...
public class HandlerThreadFactory implements ThreadFactory { @Override public Thread newThread(Runnable r) { System.out.println("创建一个新的线程"); Thread t = new Thread(r); t.setUncaughtExceptionHandler(new MyUnchecckedExceptionhandler()); ...
HandlerThread是什么 & 原理 & 使用场景? IdleHandler是什么? 一个线程能否创建多个Handler,Handler和Looper之间的对应关系? 为什么Android系统不建议子线程访问UI? Looper死循环为什么不会导致应用卡死? 可以在子线程直接new一个Handler出来吗? Message对象创建的方式有哪些 & 区别?
