What is the difference between implicit and explicit intents in Android, and how to use them?

In Android, intents come in two types: explicit and implicit.

• Explicit Intent — explicitly specifies a particular component (e.g., Activity or Service) to be started. Used when you know exactly which component you want to invoke.

  val intent = Intent(this, DetailActivity::class.java)
  startActivity(intent)
  

• Implicit Intent — does not specify a particular component, but describes an action to perform. The system chooses the appropriate application or component capable of handling this intent.

  val intent = Intent(Intent.ACTION_VIEW)
  intent.data = Uri.parse("https://example.com")
  startActivity(intent)
  

Usage:

• Use explicit intent for navigation within your app.
• Use implicit intent for interacting with other apps or system functions (e.g., open a browser, make a call, send an email).
