Android Intents: The App's Messaging System

An Intent is a message object used to request an action from another app component. It's the universal remote for an Android app, letting you start new screens (Activities), launch background tasks (Services), or ask other apps to handle a request like opening a URL. The common mistake is using an implicit intent (a general request) for internal app navigation, which can lead to security vulnerabilities if not properly configured, instead of an explicit intent (a specific request).
