Which Types of Flags are used to Run an Application on Android?

by

Following are two types of flags to run an application in Android:

  • FLAG_ACTIVITY_NEW_TASK
  • FLAG_ACTIVITY_CLEAR_TOP

In the context of Android development, there are several types of flags that can be used to run an application, but the most common one is the Intent flags. Intent flags are used to control the behavior of the components (such as activities, services, and broadcast receivers) that are started with an Intent.

Some commonly used flags include:

  1. FLAG_ACTIVITY_NEW_TASK: Used to start a new task when launching an activity.
  2. FLAG_ACTIVITY_CLEAR_TOP: If the activity being started is already running in the current task, it is brought to the foreground, and all other activities on top of it are destroyed.
  3. FLAG_ACTIVITY_SINGLE_TOP: If the activity being started is already running in the current task, it is not restarted but rather receives the new intent through the onNewIntent() method.
  4. FLAG_ACTIVITY_CLEAR_TASK: Clears all activities from the task and launches a new instance of the specified activity.

These flags are typically used when creating Intents to start activities. For example:

java
Intent intent = new Intent(context, YourActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(intent);

Keep in mind that the specific flags used will depend on the desired behavior of the application.
