Unity Science

Old rules, let's first introduce Unity's popular science knowledge:

• Unity is a real-time 3D interactive content creation and operation platform.
• All creators, including game development, art, architecture, automobile design and film and television, turn creativity into reality with Unity.
• Unity platform provides a complete set of software solutions that can be used to create, operate and realize any real-time interactive 2D and 3D content. The supporting platforms include mobile phones, tablets, PC s, game consoles, augmented reality and virtual reality devices.
• Unity can also be simply understood as a game engine, which can be used to professionally make games!

Unity calls the API to dynamically obtain Android permissions

When developing Android applications, the problem of obtaining Android permissions is often used.

There are two solutions to this problem

• One is that the method of dynamically obtaining permissions has been written on the Android side, and Unity can call this method.
• The other is to call API directly in Unity and apply for permission access (after 2019, Unity has already provided Android oriented permissions).

For Unity developers, it's convenient to directly call API on Unity side to apply for permission. Here's how to call it.
If you want to know the first method, you can see this article: How Unity interacts with Android Studio ✨ Obtain mobile phone permission (storage, recording, camera, etc.)

Unity official API link: https://docs.unity3d.com/ScriptReference/Android.Permission.html

Click the source code to see that Unity also has permission names, which means that we can also customize some permissions to pop-up windows, and we don't have to use them.

The API provided by Unity can be called directly in the script. Examples of API usage are as follows:

    private void Start()
    {
        Permission.RequestUserPermission(Permission.Camera);
        Permission.RequestUserPermission(Permission.Microphone);
        Permission.RequestUserPermission(Permission.FineLocation);
        Permission.RequestUserPermission(Permission.CoarseLocation);
        Permission.RequestUserPermission(Permission.ExternalStorageRead);
        Permission.RequestUserPermission(Permission.ExternalStorageWrite);
    }

The following is a complete example code of using Unity to dynamically apply for permission:

The first scheme:

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

public class PerTest : MonoBehaviour
{
    string[] strs = new string[] {
        "android.permission.INTERNET",
        "android.permission.READ_PHONE_STATE",
        "android.permission.READ_EXTERNAL_STORAGE",
        "android.permission.WRITE_EXTERNAL_STORAGE",
        "android.permission.ACCESS_WIFI_STATE",
        "android.permission.ACCESS_NETWORK_STATE",
        "android.permission.GET_TASKS",
        "android.permission.REQUEST_INSTALL_PACKAGES",
        "android.permission.WAKE_LOCK",
        "android.permission.SYSTEM_ALERT_WINDOW",
        "android.permission.CHANGE_WIFI_STATE",
        "android.permission.CHANGE_NETWORK_STATE",
        "android.permission.ACCESS_COARSE_LOCATION",
        "android.permission.ACCESS_FINE_LOCATION",
        "android.permission.SYSTEM_OVERLAY_WINDOW",
        "android.permission.ACCESS_COARSE_UPDATES",
        "android.permission.WRITE_SETTINGS",
        "android.permission.BATTERY_STATS",
        "android.permission.MOUNT_UNMOUNT_FILESYSTEMS"
    };

    void Start()
    {
        for (int i = 0; i <= strs.Length - 1; i++)
        {
            Permission.RequestUserPermission(strs[i]);
            Debug.Log("add permission: " + strs[i]);
        }
    }
}

The second scheme:

using System.Linq;
using UnityEngine;
using UnityEngine.Android;

public class PerTest : MonoBehaviour
{
    //An array of strings for which you want permission
    string[] strs = new string[] {
        "android.permission.INTERNET",
        "android.permission.READ_PHONE_STATE",
        "android.permission.READ_EXTERNAL_STORAGE",
        "android.permission.WRITE_EXTERNAL_STORAGE",
        "android.permission.ACCESS_WIFI_STATE",
        "android.permission.ACCESS_NETWORK_STATE",
        "android.permission.GET_TASKS",
        "android.permission.REQUEST_INSTALL_PACKAGES",
        "android.permission.WAKE_LOCK",
        "android.permission.SYSTEM_ALERT_WINDOW",
        "android.permission.CHANGE_WIFI_STATE",
        "android.permission.CHANGE_NETWORK_STATE",
        "android.permission.ACCESS_COARSE_LOCATION",
        "android.permission.ACCESS_FINE_LOCATION",
        "android.permission.SYSTEM_OVERLAY_WINDOW",
        "android.permission.ACCESS_COARSE_UPDATES",
        "android.permission.WRITE_SETTINGS",
        "android.permission.BATTERY_STATS",
        "android.permission.MOUNT_UNMOUNT_FILESYSTEMS"
    };

    void Start()
    {
        //Start dynamic request permission
        strs.ToList().ForEach(s => {
            Debug.Log("RequestUserPermission: "+s);
            if (!Permission.HasUserAuthorizedPermission(s))
            {
            Permission.RequestUserPermission(s);

            Debug.Log("add RequestUserPermission: " + s);
            }
            else
            {
                Debug.Log("it has RequestUserPermission: " + s);
            }
        });
    }
}

The third scheme:

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

public class PerTest : MonoBehaviour
{
    public static PerTest instance;
    private void Awake()
    {
        instance = this;
    }
    //Initialization, permission application should be made as early as possible
    [RuntimeInitializeOnLoadMethod(RuntimeInitializeLoadType.BeforeSceneLoad)]
    public static void Init()
    {
        //First add the permission to the list, and then apply
        AndroidPermissionMgr.permissionList.Add("android.permission.READ_PHONE_STATE");
        AndroidPermissionMgr.permissionList.Add(Permission.ExternalStorageRead);
        AndroidPermissionMgr.permissionList.Add(Permission.ExternalStorageWrite);
        AndroidPermissionMgr.permissionList.Add(Permission.FineLocation);
        AndroidPermissionMgr.permissionList.Add(Permission.CoarseLocation);
        AndroidPermissionMgr.StartCheckPermission(0.02f); //Start application

        Debug.Log("Permission application completed");
    }
}
public static class AndroidPermissionMgr
{
    static int index;
    public static List<string> permissionList = new List<string>();

    public static void StartCheckPermission(float time)
    {
        Debug.Log("Start permission application");
        if (permissionList.Count > 0)
        {
            Get(permissionList[index], time);
        }
    }

    /// <summary>
    ///External access method
    /// </summary>
    ///< param name = "type" > permission name < / param >
    ///< param name = "time" > if you refuse, how long is the delay to apply again < / param >
    static void Get(string type, float time)
    {
        if (!Permission.HasUserAuthorizedPermission(type))
        {
            Permission.RequestUserPermission(type);
            Debug.Log("Obtaining permissions for:" + type);
            PerTest.instance.StartCoroutine(Check(type, time));
        }
        else
        {
            Debug.Log("Permission obtained:" + type);

            if (index < permissionList.Count - 1)
            {
                index += 1;
                Get(permissionList[index], time);
            }
        }
    }
    static IEnumerator Check(string type, float time)
    {
        yield return new WaitForSeconds(time);
        Get(type, time);
    }
}

The pop-up window of the three schemes has the same effect, and different permissions can be added according to different permission requirements.

The following is all the Android permission tables you can refer to.
