In android when you launch an app Main or root activity is first activity to be executed. For root activity it is compulsory to have android. intent. action. MAIN and android.
To start an activity, use the method startActivity(intent) . This method is defined on the Context object which Activity extends. The following code demonstrates how you can start another activity via an intent. # Start the activity connect to the # specified class Intent i = new Intent(this, ActivityTwo.
A task is a collection of activities that users interact with when trying to do something in your app. These activities are arranged in a stack—the back stack—in the order in which each activity is opened. For example, an email app might have one activity to show a list of new messages.
Choose Edit Configuration from the list. Now from the Launch Option Select the Specified Activity and start typing in the activity text input, the android studio will automatically show you the list of all activities, select one from them or write the name of your activity.
Set root activity
Intent intent = new Intent(this, DActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
startActivity(intent);
