01 新建一个新的安卓项目

https://i-blog.csdnimg.cn/blog_migrate/6087d06e7c7025233fa7de500eb75f7b.png

项目里新建一个button

https://i-blog.csdnimg.cn/blog_migrate/5f668047296630d3d8847afd5160de77.png

实现button的点击事件进入游戏

https://i-blog.csdnimg.cn/blog_migrate/e4bbe94b9481b9de444d0be9b9aa4d84.png

package com.example.project_android;
import androidx.appcompat.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.Button;
import android.view.View;
public class MainActivity extends AppCompatActivity implements View.OnClickListener {
    private Button button1;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        button1 = findViewById(R.id.button1);
        //注册监听器
        button1.setOnClickListener(this);
    }
    @Override
    public void onClick(View view) {
        switch (view.getId()) {
            case R.id.button1:
                onClickButton1(view);
                break;
            default:
                break;
        }
    }
    private void onClickButton1(View view) {
        System.out.println("触发点击进入游戏的按钮事件");
    }
}

unity导出android工程

https://i-blog.csdnimg.cn/blog_migrate/96905adb996b01a0d356dedb85cfbaeb.png

导出的工程文件夹放入原生的安卓项目

https://i-blog.csdnimg.cn/blog_migrate/0ef1ce9c6e901d67494cd25cc788520f.png

放入如下代码

include ':unityLibrary'
project(':unityLibrary').projectDir=new File('.\\UnityAndroidProject\\unityLibrary')

https://i-blog.csdnimg.cn/blog_migrate/9d5c255b061be16a3904c39fadcf3ab2.png

放入如下代码

implementation project(':unityLibrary')
implementation fileTree(dir: project(':unityLibrary').getProjectDir().toString() + ('\\libs'), include: ['*.jar'])

https://i-blog.csdnimg.cn/blog_migrate/8f65db24f431c238cd2e9f4de6c3f24b.png

放入如下代码

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

android:process=":UnityActivity"

https://i-blog.csdnimg.cn/blog_migrate/e04b155827fb6abdfed871b519da6ddd.png

项目里添加UnityGameActivity.java

https://i-blog.csdnimg.cn/blog_migrate/6c63919e0efeeb82f7a3bd25f2c66d13.png

package com.example.project_android;
import android.os.Bundle;
import android.util.Log;
import android.view.KeyEvent;
import com.unity3d.player.UnityPlayer;
import com.unity3d.player.UnityPlayerActivity;
//进入到这个类就进入了unity游戏画面
public class UnityGameActivity extends UnityPlayerActivity {
    private static final String TAG = "UnityGameActivity";
    private boolean isFinish = false;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        SendMessageToUnity("AndroidToUnityMessage");
    }
    public void finishUnityGame(String str) {
        Log.i(TAG, "unity传给Android的信息: "+ str );
        isFinish = true;
        //关闭unity游戏返回app
        finish();
    }
    public void SendMessageToUnity(String str) {
        Log.i(TAG, "Android传给unity的信息: " + str);
        //其中GameData是unity生成的gameobject，脚本要挂在上面。AndroidToUnity是unity里实现的方法。str是传过去的值。
        UnityPlayer.UnitySendMessage("GameData", "AndroidToUnity", str);
    }
    @Override
    protected void onResume() {
        Log.e(TAG, "onResume: " );
        super.onResume();
    }
    @Override
    protected void onPause() {
        Log.e(TAG, "onPause: " );
        super.onPause();
        if (!isFinish){
            mUnityPlayer.pause();
        }
    }
    @Override
    protected void onStop() {
        Log.e(TAG, "onStop: " );
        super.onStop();
    }
    @Override
    protected void onDestroy() {
        Log.e(TAG, "onDestroy: " );
        super.onDestroy();
    }
}

需要配置，才能找到这个类

<activity android:name="com.example.project_android.UnityGameActivity" android:theme="@style/UnityThemeSelector" android:screenOrientation="landscape" android:launchMode="singleTask" android:configChanges="mcc|mnc|locale|touchscreen|keyboard|keyboardHidden|navigation|orientation|screenLayout|uiMode|screenSize|smallestScreenSize|fontScale|layoutDirection|density" android:hardwareAccelerated="false">
    <meta-data android:name="unityplayer.UnityActivity" android:value="true" />
    <meta-data android:name="android.notch_support" android:value="true" />
</activity>

unity的脚本加上可以接收信息的方法，脚本需要挂在GameData上

https://i-blog.csdnimg.cn/blog_migrate/1cc4bc3b9be566cdd26bfe72b19e4a17.png

    public void AndroidToUnity(string str)
    {
        Debug.Log("Unity接收Android信息 = " + str);
        //通过Newtonsoft.Json插件的JsonConvert.DeserializeObject方法，将json格式的string数据转换为model数据
        //UnityDataModel unityDataModel = JsonConvert.DeserializeObject<UnityDataModel>(str);
        //Debug.Log("unityDataModel.key1 = " + unityDataModel.key1);
        //Debug.Log("unityDataModel.key2 = " + unityDataModel.key2);


    }

完整代码

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Newtonsoft.Json;

public class GameData : MonoBehaviour
{
    public void IOSToUnity(string str)
    {
        Debug.Log("Unity接收IOS信息 = " + str);
        //通过Newtonsoft.Json插件的JsonConvert.DeserializeObject方法，将json格式的string数据转换为model数据
        UnityDataModel unityDataModel = JsonConvert.DeserializeObject<UnityDataModel>(str);
        Debug.Log("unityDataModel.key1 = " + unityDataModel.key1);
        Debug.Log("unityDataModel.key2 = " + unityDataModel.key2);
    }

    public void AndroidToUnity(string str)
    {
        Debug.Log("Unity接收Android信息 = " + str);
        //通过Newtonsoft.Json插件的JsonConvert.DeserializeObject方法，将json格式的string数据转换为model数据
        //UnityDataModel unityDataModel = JsonConvert.DeserializeObject<UnityDataModel>(str);
        //Debug.Log("unityDataModel.key1 = " + unityDataModel.key1);
        //Debug.Log("unityDataModel.key2 = " + unityDataModel.key2);
    }

    private void Awake()
    {
        DontDestroyOnLoad(this);
    }
}

安卓端在button的点击事件里，加上启动unity游戏的方法

private void onClickButton1(View view) {
    System.out.println("触发点击进入游戏的按钮事件");
    startActivity(new Intent(view.getContext(), UnityGameActivity.class));
}

unity导出的android sdk 和 android studio导出的android sdk版本要一致

解决：E/Unity: Failed to load ’libmain.so’问题，需要在unity做如下配置：E/Unity: Failed to load ’libmain.so’问题，需要在unity做如下配置

Unity端结束游戏时发信息给安卓端

核心代码

#if UNITY_ANDROID
            try
            {
                AndroidJavaClass jc = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
                AndroidJavaObject overrideActivity = jc.GetStatic<AndroidJavaObject>("currentActivity");
                //AndroidToUnityMessage是发送给Android的信息，finishUnityGame是安卓端接收的方法
                overrideActivity.Call("finishUnityGame", "AndroidToUnityMessage");
            }
            catch (Exception e)
            {
                Debug.Log(e.Message);
            }
#endif
