What is the purpose of the 'process' parameter in Android components and when is it used?

The process parameter in Android components (for example, in the manifest for Activity, Service, Provider, or Receiver) specifies the name of the process in which the component will run.

By default, all application components run in the main application process. Specifying android:process allows launching a component in a separate process, which is useful for:

• Offloading the main process to avoid blocking the UI.
• Isolating components with increased security or stability requirements.
• Running services that need to operate independently of the main application.

For example:

<service android:name=".MyService" android:process=":remote" />

This will create a separate process named package_name:remote for the service.
