What is AndroidManifest.xml in android ?

Question

I am new to android, can someone explain the use of AndroidManifest.xml in detail may be with an example.

Answer 1

It contains all necessary information of app and it placed in the root directory of android app. it contains info like user permission,activity names,content providers,broadcast receivers etc.
AndroidManifest.xml file is:
1.responsible to protect the application to access any protected parts by providing the permissions.
2.also declares the android API that the application is going to use.
3.lists the instrumentation classes. The instrumentation classes provides profiling and other informations. These informations are removed just before the application is published etc.
