No, it's a bad approach. You better pass WeakReference<Activity> to your methods, and implement methods like this:

public static final void showSimpleAlertDialog(final WeakReference<Activity> mReference, String  message, final boolean shouldFinishActivity) {
    Activity activity = mReference.get();
    if (activity != null) {
        //your code goes here
    }
