Android ClassNotFoundException：在路径dexpath统一插件上找不到类

Question

我在android studio中创建了统一插件。不过，我被困在这个特殊的例外。

当我作为一个应用程序编译和运行项目时，不会发生这个问题，并且只有当它作为一个库导出到统一时才会发生。

以下是错误

这里的全部日志猫是我在单位使用该插件定制清单：

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.livefurnish.livefurnish" android:versionName="1.0" android:versionCode="1"> 
<uses-sdk android:minSdkVersion="19" /> 
    <application android:label="@string/app_name"> 
     <activity android:name=".MainActivity" 
        android:label="@string/app_name"> 
      <intent-filter> 
        <action android:name="android.intent.action.MAIN" /> 
        <category android:name="android.intent.category.LAUNCHER" /> 
      </intent-filter> 
     </activity> 
    </application> 
</manifest> 

我发现并试图为众多解决方案这在互联网上，但是，当应用程序被编译为一个统一插件时，他们都没有解决这种情况。

Unity无法将所有导入的库导入到您的gradle文件中。所以你需要在Unity项目的Plugin文件夹中复制.jar文件。
