我从Java广播信息并在Unity中接收信息的错误在哪里？

所以我刚开始做这个项目，其中一部分是将信息包从Java中的一个应用发送到另一个Unity应用

我一直在努力学习，但我在使用它时遇到了一些问题，甚至有点理解它，因为我以前没有使用过Java

这是我目前掌握的代码

主要活动课 发送方类 }

发送方的XML 统一安卓清单

我意识到这是一个很大的帖子，但我现在不知道该怎么办，我正在考虑退出这个项目，因为我不知道如何让Java与Unity通信

提前感谢。

MC——这是两个不同的Android应用程序，运行在同一台Android设备上？？所以，基本上使用Android的“服务”概念。是吗？是的，两个应用程序都同时在同一部手机上运行。我让它的一部分工作起来，unity插件获取并读取字符串text=“1”；我在接收者中有，但是发送者似乎没有工作，无论我对unity.xml文件做了什么编辑，它仍然会打印来自接收者的1——这是在同一个Android设备上运行的两个不同的Android应用？？所以，基本上使用Android的“服务”概念。是吗？是的，两个应用程序都同时在同一部手机上运行。我让它的一部分工作起来，unity插件获取并读取字符串text=“1”；我在接收者中有，但是发送者似乎没有工作，无论我对unity.xml文件做了什么编辑，它仍然会从接收者打印1
