Expo集成FCM推送通知配置错误修复

执行expo build:android时出现以下错误：

Error: Problem validating fields in app.json. Learn more: https://docs.expo.dev/workflow/configuration/
• Field: android - should NOT have additional property 'androidServicesFile'.
Couldn't publish because errors were found. (See logs above.) Please fix the errors and try again.

问题原因

androidServicesFile是Expo配置根层级的属性，并非android子对象下的配置项，你把它放错了位置。另外你的app.json还存在语法错误：ios配置块缺少闭合的}。

修正后的app.json配置
