2022-07-29 05:16:00 【suelee_ hm】

Project sample source code ：

https://github.com/sueleeyu/framework

One 、 Create project project

1. unity edition 2020.2.6f1, New projects ：

2.Hieraychy Next Scene Rename it to GeospatialScene, choice Window-Package Manager- Unity Register, Download... In turn ：

XR Plugin Management 4.0.7

AR Foundation 4.1.10

ARCore XR Plugin 4.1.10

ARKit XR Plugin 4.1.10

3. as follows ：

4. Delete the original camera , Click on Hierarchy Of “+”, add to AR Session Origin and AR Session：

5. Switch project platform ,File-Build Settings, To add Scene, then Platform Next switch to Android：

6.Player Settings Set up , Click on Build Setting Under the Player Settings：

Scripting Backend choice IL2CPP, such Target Architectures You can check ARM64：

7.XR-Plugin Management：

8. Package settings : because ARCore Extensions need build gradle Plug in 4.0.1 above , When packing, you need to check the following options ：

And android Correspondence between projects ：

Main Gradle Template–> unityLibrary Library build.gradle file

Launcher Gradle Template->launcher Library build.gradle file

Base Gradle Template->android engineering build.gradle file

Gradle Properties->android engineering gradle.properties file

Otherwise, packaging errors will occur ：

9. Test Packet APK

If the packaging time is long ,

a. Open the project

\Assets\Plugins\Android\baseProjectTemplate.gradle file , Change to ：

// GENERATED BY UNITY. REMOVE THIS COMMENT TO PREVENT OVERWRITING WHEN EXPORTING AGAIN



allprojects {

    buildscript {

        repositories {**ARTIFACTORYREPOSITORY**

           maven{ url 'http://maven.aliyun.com/nexus/content/groups/public/'}

            google()

            jcenter()

        }



        dependencies {

            // If you are changing the Android Gradle Plugin version, make sure it is compatible with the Gradle version preinstalled with Unity

            // See which Gradle version is preinstalled with Unity here https://docs.unity3d.com/Manual/android-gradle-overview.html

            // See official Gradle and Android Gradle Plugin compatibility table here https://developer.android.com/studio/releases/gradle-plugin#updating-gradle

            // To specify a custom Gradle version in Unity, go do "Preferences > External Tools", uncheck "Gradle Installed with Unity (recommended)" and specify a path to a custom Gradle version

            classpath 'com.android.tools.build:gradle:4.2.2'

            jcenter()

        flatDir {

            dirs "${project(':unityLibrary').projectDir}/libs"

        }

    }

}

task clean(type: Delete) {

    delete rootProject.buildDir

}

b．\Assets\Plugins\Android\mainTemplate.gradle file , Change it to ：

//AAA Android Resolver Repos Start

([rootProject] + (rootProject.subprojects as List)).each { project ->

    project.repositories {

        def unityProjectPath = $/file:///**DIR_UNITYPROJECT**/$.replace("\\", "/")

        maven{ url 'http://maven.aliyun.com/nexus/content/groups/public/'}

        maven {

            url "https://maven.aliyun.com/repository/google/" // Assets/GoogleMobileAds/Editor/GoogleMobileAdsDependencies.xml:7

        }

        mavenLocal()

        jcenter()

        mavenCentral()

    }

}

//AAA Android Resolver Repos End

apply plugin: 'com.android.library'

If the first line is the following, it should also be deleted ：

// GENERATED BY UNITY. REMOVE THIS COMMENT TO PREVENT OVERWRITING WHEN EXPORTING AGAIN

Tips ： If we modify Unity Generated files , such as build.gradle, such as UnityPlayerActivity.java etc. , Then you can delete the following comments in these files , To prevent Unity Overlay the file ：

GENERATED BY UNITY. REMOVE THIS COMMENT TO PREVENT OVERWRITING WHEN EXPORTING AGAIN

c． open Android Resolver Set up ：

d. Cancel overwrite mainTemplate.gradle Set up ：

10. Signature packed APK： Open Command Prompt - Enter the directory where the certificate is located , Put the unsigned APK Put it in the current directory , renamed orient.apk, Command line input ：

jarsigner -verbose -keystore user.keystore -signedjar sign.apk orient.apk 212

user.keystore For certificate , Such as ：F:\unity\sign\user.keystore

orient.apk Is unsigned APK, Such as ：F:\unity\sign\orient.apk

sign.apk For the signed APK

212 Alias set for Certificate creation

11. see SHA-1 The fingerprint , Command line input ：

keytool -list -printcert -jarfile sign.apk

Two 、 install ARCore Extensions software package （ It does not involve geospatial and cloud anchors, and there is no need to install ）

Installation requirements ：

1. Over the wall

2.ARCore The expansion pack requires ARFoundation4.1.5 above .

3.unity edition 2020.2.6f1 above

google Reference documents ：

6. stay Unity in , go to Edit > Project Settings > XR > ARCore Extensions. Android Authentiation Strategy Drop down menu , choice API Key

7. stay Android API Key Field , Paste from Google Cloud Platform To obtain the API secret key （ Following ）, And check the Optional Features The next two are to be used API Check box ：

Authorization complete .

3、 ... and 、 add to UI

1.Hierarchy Right click -Create Empty, Click on the created component , On the right side Inspector name UI.Hierarchy Right click -Create Empty, Click on the created component , On the right side Inspector name Game：

2.UI Under the new Text, name Log, Set up ：

Four 、 Add a script

1. Assets- newly build Scripts Folder , newly build Logger.cs Script files ：

using System.Collections.Generic;

using System.Text;

using UnityEngine;

using UnityEngine.UI;



namespace FrameworkDesign.Example

{

    public class Logger : MonoBehaviour

    {

        [SerializeField]

        Text m_LogText;

        public Text logText

        {

            get => m_LogText;

            set => m_LogText = value;

        }



        [SerializeField]

        int m_VisibleMessageCount = 40;

        public int visibleMessageCount

        {

            get => m_VisibleMessageCount;

            set => m_VisibleMessageCount = value;

        }



        int m_LastMessageCount;



        static List<string> s_Log = new List<string>();



        static StringBuilder m_StringBuilder = new StringBuilder();



        void Awake()

        {

            if (m_LogText == null)

            {

                m_LogText = GetComponent<Text>();

            }



            lock (s_Log)

            {

                s_Log?.Clear();

            }



            Log("Log console initialized.");

        }



        void Update()

        {

            lock (s_Log)

            {

                if (m_LastMessageCount != s_Log.Count)

                {

                    m_StringBuilder.Clear();

                    var startIndex = Mathf.Max(s_Log.Count - m_VisibleMessageCount, 0);

                    for (int i = startIndex; i < s_Log.Count; ++i)

                    {

                        m_StringBuilder.Append($"{i:000}> {s_Log[i]}\n");

                    }



                    var text = m_StringBuilder.ToString();



                    if (m_LogText)

                    {

                        m_LogText.text = text;

                    }

                    else

                    {

                        Debug.Log(text);

                    }

                }



                m_LastMessageCount = s_Log.Count;

            }

        }



        public static void Log(string message)

        {

            lock (s_Log)

            {

                if (s_Log == null)

                    s_Log = new List<string>();



                s_Log.Add(message);

            }

        }

    }

}

2. mount Log, choice Log Components , take Logger.cs Drag to add as Component, relation Log（ Drag the Log To LogTest bar ）
