Download Manager

Regarding the monitoring of download progress, this is relatively simple. Taking APK file download as an example, three callback functions need to be processed, namely:

1. Downloading 2. Downloading succeeded 3. Downloading failed

The next step is to manage the thread pool. Of course, you can also directly use several static methods provided in the executors tool class to create the thread pool. Here I create the thread pool manually. The code is as follows:

The next step is the encapsulation of a download manager

The tool classes involved are as follows: pathutils

CmdUtils

OK, the following code can directly update APK
