There are three basic ways to download Android files

1、 Encapsulate urlconnection connection request class

When Android was just emerging, this method rarely downloaded the packaging framework and encapsulated it by itself. Although general files can be downloaded, this method has many disadvantages, instability or various problems.

2、 Android customized Download Management (the download progress will be displayed in the notification, and you can pause, reconnect, etc.)

This method is actually handed over to another app of the Android system for download management. This benefit will not consume the CPU resources of the app. The disadvantage is that the control is very inflexible.

3、 Using third-party okhttp network request framework

Okhttp is a well-known open source framework. At present, many large companies directly use it as the network request Library (qiniu cloud SDK and Alibaba cloud SDK). It integrates many advantages, including okio (an I / O framework that optimizes memory and CPU).
