uniapp离线打包app无法调用相机权限的解决思路

场景：uniapp离线打包后的app,在android12以上的机型，无法调用相机权限

解决办法：这里我认为uniapp中的mainfest.json中虽然配置了App权限，但是打包不生效。然后我试着App权限加到AndroidManifest.xml中去，发现离线打包后的app可以调用相机权限声明了。

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.xxx.app">
    //将权限声明全部加到这里来（关键）

    <uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS"/>
    <uses-permission android:name="android.permission.READ_CONTACTS"/>
