Get current foreground activity context in android

GetCurrentForegroundActivity.java

public static Activity getActivity() {
        try {
            Class activityThreadClass = Class.forName("android.app.ActivityThread");
            Object activityThread = activityThreadClass.getMethod("currentActivityThread").invoke(null);
            Field activitiesField = activityThreadClass.getDeclaredField("mActivities");
            activitiesField.setAccessible(true);

            Map<Object, Object> activities = (Map<Object, Object>) activitiesField.get(activityThread);
            if (activities == null)
                return null;

            for (Object activityRecord : activities.values()) {
                Class activityRecordClass = activityRecord.getClass();
                Field pausedField = activityRecordClass.getDeclaredField("paused");
                pausedField.setAccessible(true);
                if (!pausedField.getBoolean(activityRecord)) {
                    Field activityField = activityRecordClass.getDeclaredField("activity");
                    activityField.setAccessible(true);
                    return (Activity) activityField.get(activityRecord);
                }
            }

            return null;
        }
        catch (Exception e)
        {
            return null;
        }
    }

Will this work in Android 9.0?
