About intent in Android development (intent)

Intent connecting two different components during program run (acvivity)

For example, when we click on a contact on the phone to view its information, we need to tell Android via intent, I want to do a "view" action

To achieve the jump from interface A to interface B

Declaration method: Intent Intent = new Intent (mainactivity.this, Otheractivity.class);

Mainactivity for the above a,otheractivity for B in the above

And otheractivity is from the manifest to look for, such as:

So the name here must correspond, otherwise the program will run, but the run-time error

Finally, the intent is passed in by startactivity (intent) and the corresponding action is taken.
