public class FlashIntentUtils {
    private static volatile FlashIntentUtils instance = null;

    private FlashIntentUtils(){
    }

    public static FlashIntentUtils getInstance() {
        if (instance == null) {
            synchronized (FlashIntentUtils.class) {
                if (instance == null) {
                    instance = new FlashIntentUtils();
                }
            }
        }

        return instance;
    }
    private Object object;
    public void putExtra(Object object) {
        this.object = object;
    }
    public Object getExtra() {
        Object extra = object;
        this.object = null;
        return extra;
    }
}

当然也有其他方式，比如写入文件或者sqlite里面。
