Explicit activity While creating an Intent object when we explicitly specify and pass on the target component name directly in the intent, it’s an explicit intent.Explicit Intents are used to call a specific component. When you know which component you want to launch and you do not want to give the user free control over which component to use.For example, you have an application that has 2 activities. Activity A and activity B. You want to launch activity B from activity A. In this case you define an explicit intent targeting activityB and then use it to directly call it.
You make a call that indicate exactly which activity class:
Intent intent = new Intent(this, ActivityABC.class);
