You can use the BroadcastReceiver Class. Try this way.

public class MyBroadcastReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {

        if (isAppForground(context)) {
            // App is in Foreground
        } else {
            // App is in Background
        }
    }

    public boolean isAppForground(Context mContext) {

        ActivityManager am = (ActivityManager) mContext.getSystemService(Context.ACTIVITY_SERVICE);
        List<RunningTaskInfo> tasks = am.getRunningTasks(1);
        if (!tasks.isEmpty()) {
            ComponentName topActivity = tasks.get(0).topActivity;
            if (!topActivity.getPackageName().equals(mContext.getPackageName())) {
                return false;
            }
        }

        return true;
    }
