Unity2019.4.4
AndropidStudio4.2.1
参考文档:
Android内嵌Unity并实现互相跳转的实例代码_Android_脚本之家
Android Fragment中加载,嵌套Unity视图_unity 导入并作为fragment_周灬浩的博客-CSDN博客
本文只实现了Activity整个切换过去,而Fragment,这种像h5似的与app共存,目前还未实现,可参考的第二个链接
1、在空场景中创建一个空节点名字为unityObject(这个名字安卓调用unity用到)
然后在节点上添加一个脚本
using UnityEngine;
using UnityEngine.SceneManagement;
using UnityEngine.UI;
/// <summary>
/// 安卓 unity交互
/// </summary>
public class AndoridAndUnity : MonoBehaviour
{
public static AndoridAndUnity instance;
AndroidJavaObject jo;
private void Awake()
{
Debug.Log("AndoridAndUnity Awake");
instance = this;
//RunGameScene("Test");
DontDestroyOnLoad(this);
}
private void Start()
{
Debug.Log("AndoridAndUnity Start");
//Debug.Log("AndoridAndUnity 包名:"+ Application.identifier);
//Debug.Log("AndoridAndUnity 版本号:" + Application.version);
}
//安卓回掉unity
void fromAndroid(string str)
{
Debug.Log("安卓传来信息 : " + str);
}
//安卓回掉unity
void RunGameScene(string str)
{
Debug.Log("切换场景 : " + str);
SceneManager.LoadScene(str);
}
//返回app
public void GoBack()
{
PlayerPrefs.Save();
Debug.Log("AndoridAndUnity GoBack");
AndroidJavaClass jc = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
jo = jc.GetStatic<AndroidJavaObject>("currentActivity");
jo.Call("goBack");//调用Android中函数
//Application.Quit();
}
string str;
private void OnGUI()
{
GUI.color = Color.white;
//GUI.Label(new Rect(10, 100, 200, 40), str);
if (GUI.Button(new Rect(10, 20, 200, 80), "返回"))
{
//str = "点击成功";
GoBack();
}
}
}
然后在Build Settings中将平台切换到Android
Unity项目目录与(下面新建的)安卓项目目录之间的关系:
2、创建安卓项目
选择NoActivity->Next
尽量保持一致,不一致也是以安卓的为准
NativeAndroidApp 中settings.gradle文件添加代码,将导出的unity库导入到安卓项目中(unityLibrary 的路径就是导出放置的路径有关)
include ':unityLibrary'
project(':unityLibrary').projectDir = new File('..\\androidBuild\\unityLibrary')
在应用级build.gradle中加入so库和dependencies相应的unity依赖 在应用级build.gradle中加入so库和dependencies相应的unity依赖
android {
defaultConfig {
***
ndk {
// 设置支持的SO库架构,第三方给的so库哪几种架构,就配置这几种架构
abiFilters 'armeabi', 'armeabi', 'x86', 'armeabi-v7a', 'x86_64', 'arm64-v8a'
}
}
}
dependencies {
implementation project(':unityLibrary')
implementation fileTree(dir: project(':unityLibrary').getProjectDir().toString() + ('\\libs'), include: ['*.jar'])
***
}
在根级build.gradle(Module:NativeAndroidApp)中 加入
allprojects {
repositories {
google()
jcenter()
// Add Code
flatDir {
dirs "${project(':unityLibrary').projectDir}/libs"
}
// End
}
}
引用完成就能在项目中看到unityLibrary,并修改unityLibrary下面的AndroidManifest.xml文中
3、构建安卓布局和加入调用代码
选择 NativeAndroidApp 的 strings.xml 添加
<string name=
"game_view_content_description"
>Game view</string>
构建一个ui布局,并加入button按钮
MainActivity.java
package com.fancy.rush;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main_unity);
Button btn=(Button) findViewById(R.id.button);
btn.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View v) {
Log.d("/Unity", "UnityActivity");
Intent intent = new Intent(MainActivity.this, UnityActivity.class);
intent.putExtra("sceneLevel","MatchAndMerge");//传递参数,利用传递的参数可以切换场景,或者数据之类的
startActivity(intent);
}
});
}
}
UnityActivity.java
import android.os.Bundle;
import android.util.Log;
import com.unity3d.player.UnityPlayer;
import com.unity3d.player.UnityPlayerActivity;
import com.unity3d.player.UnityPlayer;
public class UnityActivity extends UnityPlayerActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Intent intent=getIntent();
String sceneLevel=intent.getStringExtra("sceneLevel");
testSendMessage(sceneLevel);
}
//当unity场景设置为常驻activity时,就需要运用到,常驻场景goBack切换出去后,再次打开时不会再周OnCreate,而是走onNewIntent
@Override protected void onNewIntent(Intent intent)
{
super.onNewIntent(intent);
String sceneLevel=intent.getStringExtra("sceneLevel");
testSendMessage(sceneLevel);
}
// 向unity发送信息
public void testSendMessage(String sceneLevel)
{
//获取意图对象
Log.d("/Unity", "testSendMessage sceneLevel:"+sceneLevel);
UnityPlayer.UnitySendMessage("unityObject", "fromAndroid", "UnityActivity");
//利用传递的参数切换场景
//第一个参数是Unity中一个节点对象的名字,第二个参数是节点对象上挂的脚本中一个函数的名字,第三个参数是函数中的参数值
//UnityPlayer.UnitySendMessage("unityObject", "RunGameScene", sceneLevel);
}
public void goBack()
{
// unity点击按钮跳转回安卓界面
Intent intent = new Intent(this, MainActivity.class);
this.startActivity(intent);
}
}
再unity和app间相互切换会出现奔溃现象,只要把UnityActivity设置为 singleTask,常驻就不会被清除掉,再次调用打开unity就不会奔溃
