unity 打包获取android手机系统权限

查了一下资料，unity里面自带有动态获取用户权限的方法Permission，需要UnityEngine.Android命名空间，使用动态获取接口RequestUserPermissions，参数是一个string数组类型参数
测试代码：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.Android;
using UnityEngine.UI;

public class PermissionMgr : MonoBehaviour
{
    
    
    // Start is called before the first frame update
    void Start()
    {
    
    
        string[] NowTypes = new string[]{
    
    
            "android.permission.MANAGE_DOCUMENTS",
            "android.permission.DELETE_CACHE_FILES",
            "android.permission.READ_OWNER_DATA",
            "android.permission.INTERNET",
            "android.permission.ACCESS_WIFI_STATE",
            "android.permission.ACCESS_FINE_LOCATION",
            "android.permission.ACCESS_LOCATION_EXTRA_COMMANDS",
            "android.permission.READ_SMS",
            "android.permission.RECEIVE_SMS",
            "android.permission.ANSWER_PHONE_CALLS",
            "android.permission.PROCESS_OUTGOING_CALLS",
            "android.permission.READ_CONTACTS",
            "android.permission.READ_CALENDAR",
            "android.permission.RECORD_AUDIO",
            "android.permission.STATUS_BAR",
            "android.permission.EXPAND_STATUS_BAR",
            "android.permission.INSTALL_PACKAGES",
            "android.permission.WAKE_LOCK",
        };
        Permission.RequestUserPermissions(NowTypes);
    }

    // Update is called once per frame
    void Update()
    {
    
    
        
    }
}

安卓权限可以去这里查看一下，引用一下这位大佬的：
安卓权限归纳引用

最重要的是：动态获取需要修改unity安装目录下的UnityManifest.xml文件：

这是我的目录：D:\Unity\Editor\Data\PlaybackEngines\AndroidPlayer\Apk（右键unity桌面图标打开目标文件夹）

只需要在：“</manifest>”上面添加需要获取的权限就可以了

<?xml version="1.0" encoding="utf-8"?>
<!-- GENERATED BY UNITY. REMOVE THIS COMMENT TO PREVENT OVERWRITING WHEN EXPORTING AGAIN-->
<manifest
    xmlns:android="http://schemas.android.com/apk/res/android"

        <activity android:name="com.unity3d.player.UnityPlayerActivity"
                  android:theme="@style/UnityThemeSelector">

            </intent-filter>
            <meta-data android:name="unityplayer.UnityActivity" android:value="true" />
        </activity>

打包之后测试：没问题，可以获取对应权限
