Creating an intent inside child activity rather than parent activity while starting an activity

What is the difference in terms of perfomance and optimization if while starting an activity i create an intent inside Child Activity(Activity to be started) rather than in parent Activity(Activity which is starting an new activity).

Example-

ChildActivity.class

public static Intent createIntent(Context context) {
    return new Intent(context, ChildActivity.class);
}

ParentActivity.class

     startActivity(ChildActivity.createIntent(ParentActivity.this));

Is it a good practice?Will this approach have any advantage if same activity is being started from multiple activities?

We can use that practice, so that we can start an Activity from any activities by calling a static method, we will save a lot of duplicate code. For me, I create a Navigator class, this class will store all methods which start activity:

public class Navigator {
    public static final String VENUE_EXTRA = "venue_extra";

    private Navigator() {

    }

    public static void navigateToOnboarding(Activity activity) {
        Intent intent = new Intent(activity, OnboardingActivity.class);
        ActivityCompat.startActivity(activity, intent, null);
    }

    public static void navigateToSharing(Activity activity, Venue venue) {
        Intent intent = new Intent(activity, SharingActivity.class);
        intent.putExtra(VENUE_EXTRA, venue);
        ActivityCompat.startActivity(activity, intent, null);
    }

    public static void navigateToAppSetting(Activity activity) {
        Intent intent = new Intent();
        intent.setAction(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
        intent.addCategory(Intent.CATEGORY_DEFAULT);
        intent.setData(Uri.parse("package:" + activity.getPackageName()));
        intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        intent.addFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);
        intent.addFlags(Intent.FLAG_ACTIVITY_EXCLUDE_FROM_RECENTS);
        activity.startActivity(intent);
    }
}
