What does Android manifest xml file

Among other things, the manifest does the following:
–It names the Java package for the application. The package name serves as a unique identifier for the application.
–It describes the components of the application —the activities, services, broadcastreceivers, and contentprovidersthat the application is composed of.
–It names the classesthat implement each of the components and publishes theircapabilities(for example, which Intent messages they can handle). These declarations let the Android system know what the components are and under what conditions they can be launched.
–It determines which processes will hostapplicationcomponents.
–It declares which permissionsthe application must have in order to access protected parts of the API and interact with other applications.
–It also declares the permissions that others are required to have in order to interact with the application's components.
–It lists the Instrumentationclasses that provide profiling and other information as the application is running. These declarations are present in the manifest only while the application is being developed and tested; they're removed before the application is published.
–It declares the minimum level of the Android API that the application requires.
–It lists the librariesthat the application must be linked against.
