You don't need to explicitly add activity in your main project's manifest if you have already added the activity in your library's manifest by using the following code when starting library's activity.

For Kotlin

   val myIntent = Intent(activityContext, ActivityToLaunch::class.java)
    // Needed to set component to remove explicit activity entry in application's manifest
    myIntent.component = ComponentName(activityContext, PickerActivity::class.java)
    activityContext.startActivity(myIntent, PICKER_REQUEST_CODE)

For Java

    Intent myIntent = new Intent(activityContext, PickerActivity.class);
    // Needed to set component to remove explicit activity entry in application's manifest
    final ComponentName component = new ComponentName(activityContext, PickerActivity.class);
    myIntent.setComponent(component);
    activityContext.startActivity(myIntent, REQUEST_CODE);
