When should you use Intents in Android development?

Intents are a fundamental building block in Android development that allow for communication between different components of an app and even between different apps. Here are some scenarios where using Intents is appropriate:

  • Starting a New Activity: You can use Intents to start a new activity within your app.
  • Launching Camera or Other Apps: Intents can be used to launch external applications, such as the camera or a web browser.
  • Sending Data: Intents allow you to send data between different components, such as starting an activity with extra data.
  • Receiving Broadcasts: You can register for specific events using Intents, which allows your app to receive broadcasts from other applications.

Here’s a simple example of using an Intent to start a new activity:

Intent intent = new Intent(CurrentActivity.this, NewActivity.class); intent.putExtra("key", "value"); startActivity(intent);
