Unity package to obtain android mobile phone system permissions

After checking the information, Unity has its own method Permission to dynamically obtain user permissions. It requires the UnityEngine.Android namespace and uses the dynamic acquisition interface RequestUserPermissions. The parameter is a string array type parameter. Test code
:

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()
    {
    
    
        
    }
}

You can go here to check Android permissions and quote this guy:

The most important thing is: dynamic acquisition requires modifying the UnityManifest.xml file in the unity installation directory:

This is my directory: D:\Unity\Editor\Data\PlaybackEngines\AndroidPlayer\Apk (right-click the unity desktop icon to open the target folder). Just add the

permissions you need to obtain above: "</manifest>"

<?xml version="1.0" encoding="utf-8"?>

Test after packaging: No problem, you can obtain the corresponding permissions
