The Android API clearly requires time-consuming operations to be run in a sub-thread, and the download of the file will undoubtedly take a while. So you want to put the download of the file in a child thread to run.Below, we work together to implement a sample of Android that uses multithreading to download fil

-time annotations, which we can access with Java reflection, and the purpose of run-time annotations is usually to provide instructions to programs and Third-party APIs.
Annotation Basics
A simple Java annotation resembles the @entity. Where @ means to tell the compiler that this is an annotation. And entity is the name of the annotation. Usually in the document, the following is written
Public @interface Entity {}

Java annotations can use elements to set values that

When working with an XML file, you may experience a situation where the file contains sensitive data, and your favorite XML processing tool has a problem, such as a bug. You need to provide the vendor with a sample file that causes a bug. Of course, you can't send an XML file randomly because it may be a special tag in the sample file that is causing the problem. You need a way to clear sensitive data in a
