APP封装是形成APP的最省钱的一种方式。你只需要拥有一个网址就可以通过一些技术处理封装成一个跨iOS和Android的APP,这个过程往往只需要几分钟。在移动互联网时代,拥有一个移动端APP是必不可少的。那么APP是怎样封装的呢?
APP封装实现
封装APP大多指Web app封装,web app 是一种架构型APP开发方式,通过使用框架(HTML5 APP
框架开发模式)无论是iOS还是Android,都可以实现跨平台运行。通过这个框架,你可以把网址封装成APP,安装到手机设备上。网址简单说就是一个个网页(html5)组成的,封装成APP之后打开的的类似浏览器访问网页(html5)一样,因此网页(html5)访问手机硬件、手机权限等都会受到限制。
Web app封装
优点:
1、可以直接封装成APP,成本低
2、只要有网站(网址)就可以封装成APP,
3、一次封装生成跨端APP
4、代码维护方便,版本更新灵活,不受原生限制
缺点:
1、用户手机端体验感较差,长时间可能降低用户信任度
2、原生功能使用受限,性能远不如原生
由此引发出混合开发APP,在保持webapp便捷开发的基础上,使用原生性能,提升用户体验。混合开发APP(Hybrid app)使用框架(HTML5 +
原生框架)跨端生成iOS和Android APP。相比hybrid app可以使用原生的能力,体验感更好。
Hybrid app封装
优点:
1、需要使用HTML5 + 原生框架来开发APP,开发完成封装成APP,成本较低
2、一次封装生成跨端APP
3、代码维护方便,版本更新快
4、用户体验感好,用户留存度高
5、支持原生功能使用,性能优于web app
缺点:
1、版本更新,如果是原生的问题,需要重新上架应用市场
2、原生功能使用受限,性能不如原生
