Unity2020以后版本调用aar包安装Apk

由于unity调整，已经无法继承UnityPlayerActivity

已过时

所以更新一下以前的文章
使用as，新建工程Empty Activity 包名com.join.testar

修改MainActivity：
继承Activity，测试方法add
package com.join.testar;import android.app.Activity;import android.content.Context;import android.content.Intent;import android.net.Uri;import android.os.Build;import android.os.Bundle;import android.widget.Toast;import androidx.core.content.FileProvider;import java.io.File;public class MainActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); //setContentView(R.layout.activity_main); } public int Add(int a,int b){ return a+b; }public void InstallApk(Context context, String apkPath){ File file = new File(apkPath); Intent intent = new Intent(Intent.ACTION_VIEW); if(Build.VERSION.SDK_INT>=24) { //Android 7.0及以上 intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION); Uri apkUri = FileProvider.getUriForFile(context, context.getPackageName()+".fileprovider", file); //对目标应用临时授权该Uri所代表的文件 intent.setDataAndType(apkUri, "application/vnd.android.package-archive"); }else{ intent.setDataAndType(Uri.fromFile(file), "application/vnd.android.package-archive"); intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); } context.startActivity(intent); }}
project视图下删除选中文件夹，

values文件夹下的xml内容都可以删除

res文件夹下新建xml目录、filepaths.xml

filepaths文件内容
<?xml version="1.0" encoding="utf-8"?><paths> <external-path       name="external_storage_root"       path="." /> <files-path       name="files-path"       path="." /> <cache-path       name="cache-path"       path="." />  <external-files-path       name="external_file_path"       path="." />  <external-cache-path       name="external_cache_path"       path="." />  <root-path       name="root-path"       path="" /></paths>修改AndroidManifest

<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.join.testar"> <application       android:allowBackup="true">       <provider          android:name="androidx.core.content.FileProvider"          android:authorities="${applicationId}.fileprovider"          android:grantUriPermissions="true"          android:exported="false">          <meta-data             android:name="android.support.FILE_PROVIDER_PATHS"             android:resource="@xml/filepaths" />       </provider> </application> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.REPLACE_EXISTING_PACKAGE"/> <uses-permission android:name="android.permission.REQUEST_INSTALL_PACKAGES"/></manifest>
目的是添加fileprovider 声明读写目录、相关权限
修改build.grade

id 'com.android.library'//改为library输出}android { compileSdk 30 defaultConfig {    //  applicationId "com.join.testar"//注释       minSdk 21       targetSdk 30       versionCode 1       versionName "1.0"       testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner" } buildTypes {       release {          minifyEnabled false          proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'       } } compileOptions {       sourceCompatibility JavaVersion.VERSION_1_8       targetCompatibility JavaVersion.VERSION_1_8 }}dependencies { implementation 'androidx.appcompat:appcompat:1.2.0' implementation 'com.google.android.material:material:1.3.0' implementation 'androidx.constraintlayout:constraintlayout:2.0.4' // testImplementation 'junit:junit:4.+'  //  androidTestImplementation 'androidx.test.ext:junit:1.1.2' // androidTestImplementation 'androidx.test.espresso:espresso-core:3.3.0'}
新建class第三方类

JavaCTest.java

package com.join.testar;import android.content.Context;public class JavaCTest { private static JavaCTest instance; public static JavaCTest Instance(){ if(instance==null) instance=new JavaCTest(); return instance; } public int Sub(int a,int b){ return a-b; }}
as工程施工完毕
sync一下，就可以build输出了

找到输出arr文件app-debug.aar

复制到unity Plugins目录下
复制androidx.core类库

复制到unity Plugins目录下

unity代码部分

新建mono脚本
编写代码调用MainActivity中的方法
AndroidJavaObject Main = new AndroidJavaObject("com.join.testar.MainActivity");int s = Main.Call<int>("Add", 2, 8);
调用javactest中的方法
AndroidJavaObject jc = new AndroidJavaObject("com.join.testar.JavaCTest");var jo = jc.CallStatic<AndroidJavaObject>("Instance");int s = jo.Call<int>("Sub", 3, 2);
可以打包运行看是否调用到了
安装apk

首先是下载apk到Application.persistentDataPath 目录
string remote = "http://192.168.1.1:5569/Root/3.apk"; string down = Application.persistentDataPath + "/3.apk"; UnityWebRequest request = UnityWebRequest.Get(remote); yield return request.SendWebRequest(); byte[] d = request.downloadHandler.data; File.WriteAllBytes(down, d);//调用 AndroidJavaObject activity = new AndroidJavaClass("com.unity3d.player.UnityPlayer"); AndroidJavaObject context = activity.GetStatic<AndroidJavaObject>("currentActivity"); string downapk = Application.persistentDataPath + "/3.apk"; AndroidJavaObject Main = new AndroidJavaObject("com.join.testar.MainActivity"); Main.Call("InstallApk", context, downapk);
至此完毕
区别就是需要传入获取到的context
