【Android】Android与Unity安卓AR通信（3）
unity导出作为安卓项目中的库来使用
- 首先打开一个安卓项目
- 准备好unity中Export出的安卓包
unity
在unity中勾选
然后export
安卓
打开一个现有的，取消gradle的下载，在Project Structure中设置自己下好了的gradle版本，如下是我的版本
1. 找不到unityStreamingAssets文件错误
在gradle.properties里添加如下代码
unityStreamingAssets=.unity3d, google-services-desktop.json, google-services.json, GoogleService-Info.plist
- 找不到NDK
Location specified by ndk.dir (D:\AndroidTool\TEMP\android-ndk-r16b) did not contain a valid NDK
ndk.dir=D\:/Unity/UntiyDownLoad/2020.3.26f1c1/Editor/Data/PlaybackEngines/AndroidPlayer/NDK
尝试将Unity中AR项目导入到AS
解决方案：
1.删掉setting.gradle中的部分代码
2.将项目的build.gradle更改
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
google()
mavenCentral()
}
dependencies {
classpath"com.android.tools.build:gradle:7.0.4"
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
buildscript {
repositories {
google()
jcenter()
}
}
repositories {
google()
jcenter()
flatDir {
dirs"${project(':unityLibrary').projectDir}/libs"
}
}
}
taskclean(type: Delete) {
deleterootProject.buildDir
}

importandroid.content.Intent;
importandroid.os.Bundle;
importandroid.view.View;
importandroid.widget.Button;

setContentView(R.layout.activity_main);
Buttonbutton=(Button)findViewById(R.id.button);
button.setOnClickListener(newView.OnClickListener() {
@Override
publicvoidonClick(Viewview) {
Intentintent=newIntent(MainActivity.this,UnityPlayerActivity.class);
startActivity(intent);
}
});
}
}
