Android Application Components

The components are the building blocks of the application as the user can do operations only after entering through components. It may be dependent or independent.

The components of the application are as follows:

The email is the application in which there are so many options like composing email inbox, spam, and starred, etc these all are the activities. There are so many activities which can run in a single application.  If this will happen then a single activity out of so many activities marked as the activities which are presented the application in front of a user.

The data which is downloaded from some device or web communicate the particular applications through the broadcast receivers.

Content Providers - The supply of data from the one application to another when you requests for it so this component i.e. is content provider helps to move data from one application to another. To perform transactions from one application to another the bunch of API’s are set up by the content providers.
