startActivityForResultIntent

StartActivityForResult is a method in Android development used to start another activity and receive a result back from it. This method is part of the Activity class and is commonly used for scenarios where one activity needs to perform an action and then return data to the calling activity. The method takes three parameters: the Intent that describes the activity to be started, a request code that identifies the request, and an options bundle that can be used to specify additional options for the activity.

When the started activity finishes, it can return a result to the calling activity using the setResult method. The result is then received in the onActivityResult method of the calling activity, where it can be processed as needed. The request code passed to startActivityForResult is used to identify which request the result corresponds to, allowing the calling activity to handle multiple requests if necessary.

StartActivityForResult is a powerful tool for creating complex user interfaces and workflows in Android applications. However, it is important to use it judiciously, as starting too many activities can lead to a poor user experience and increased memory usage. Additionally, the use of startActivityForResult is deprecated in newer versions of Android, and developers are encouraged to use alternative approaches such as Activity Result API or Jetpack Navigation Component for similar functionality.
