Android Application Development (AND-401) — Question 61

Which method should you use to start a sub-activity?

Answer options

• A. startActivity(Intent intent)
• B. startActivityForResult(Intent intent , int requestCode)
• C. startService(Intent intent)
• D. startSubActivity(Intent intent)

Correct answer: B

Explanation

The correct method to begin a sub-activity is startActivityForResult(Intent intent, int requestCode), as it allows for the parent activity to receive a result back from the sub-activity. The other options, such as startActivity and startService, do not facilitate this two-way communication, while startSubActivity is not a valid method in Android development.
