1 获取微信小程序的 AppID

首先登录>

1、Android开发

主要开发语言是Java（当然还有Kotlin/Scala/Groovy，暂时不在本文讨论的范围内）；

另外使用xml文件来描述界面；

使用xmlgradle文件来配置项目；

2、微信小程序开发

主要开发语言是javascript；

使用wxmlwxss文件来描述界面；

使用appjsonappwxss文件来配置项目；

3、微信小程序开发仅最近新增的能力：

允许个人开发者申请注册小程序、

公众号可以打开小程序、

可以在App分享、

支持识别二维码打开小程序、

可以支持第三方平台配置、

新增数据分析接口、

代码包大小从1M扩大到2M、

推出小程序码、

公众号关联小程序新规则、

公众平台新增快速创建小程序、

从开发费用来看，安卓Android开发难度高，费用高。小程序只需要开发一个版本，具有跨手机 *** 作系统平台的兼容性，因此开发费用相对较低。另外微信小程序的开发模式是比原生Andorid要先进一些的。
