Androidmanifest.xml Introduction

This file is set in every Android program and is located in the root directory of the entire project, describing the components exposed in the package (Activity,service ...), the respective implementation classes, the various data that can be processed, and the location of the boot.

In addition to being able to declare four components, programmers often need to set important user permissions.
