How to combine Intent flags in Kotlin

In Kotlin (as in Java), you can combine Intent flags using the or operator (||) to set multiple flags for an Android Intent. Intent flags are used to configure various behaviors and options when starting activities or services in Android. Here's how you can combine multiple flags for an Android Intent in Kotlin:

import android.content.Intent

// Create an Intent
val intent = Intent(context, MyActivity::class.java)

// Combine multiple flags using the 'or' operator '|'
intent.flags = Intent.FLAG_ACTIVITY_CLEAR_TOP or Intent.FLAG_ACTIVITY_SINGLE_TOP

// Start the activity with the combined flags
startActivity(intent)

In the above code:

  1. We create an Intent object to launch an Activity (in this case, MyActivity).

  2. We combine multiple flags using the or operator (|). In this example, we use Intent.FLAG_ACTIVITY_CLEAR_TOP to clear the back stack and Intent.FLAG_ACTIVITY_SINGLE_TOP to reuse the existing instance of the activity if it's already in the foreground.

  3. We set the combined flags to the flags property of the Intent object.

  4. Finally, we start the activity using the startActivity(intent) method, which will apply the combined flags.

You can combine different flags as needed for your specific use case by using the or operator (|).
