我们有一个ReactNative应用程序,它已经成功地将基于react-native-unity-view的Unity集成为一个库很长时间了。但是,在最近对ReactNative进行了有关AndroidX和最新SDK更改的更新后,我们遇到了问题**”libmain.so not found”**。在第一次尝试显示Unity-View时会发生此异常。
- 在SO上有类似的issue,请不要标记为重复,因为我们的方法可能会有所不同,而且我们在这里给予了更多的详细信息。*
在GitHub上有一个正在运行且仍在工作的示例(基于ReactNative 0.57):https://github.com/f111fei/react-native-unity-demo。只要这个项目是基于ReactNative 0.57及其适当的gradle设置,一切都可以正常工作。但一旦我们升级到最新的ReactNative版本(甚至是0.60),它会给我们一个与旧版本非常不同的android文件夹),这个问题发生在应用程序崩溃的时候。2(我们也试着从头开始设置所有的东西,以排除这个问题是由于升级的可能性。3使用RN0.57,所有的东西仍然工作的很好,RN为0.60及以上时不适用)*
例外情况如下:
E Unity : Failed to load 'libmain.so', the application will terminate.
D AndroidRuntime: Shutting down VM
E AndroidRuntime: FATAL EXCEPTION: main

首先,我将列出最新版本中发生崩溃的android文件夹和gradle文件。然后,我将列出所有运行正常的文件:

根据official Unity2D-Forums中的这个问题,有一些其他报告,但没有任何有效的解决方案。根据评论,我们知道在两个build.gradle-文件中使用了非常相同的abiFilter-设置(这来自我们的应用程序和UnityExport的build-gradle),但它也没有解决这个问题。
有人能帮忙吗?

我现在可以自己回答了。这个问题是由Unity导出导致的,它不兼容ARM64,除非手动应用了几个设置。下面是方法:
在为Android构建之前,我们需要调整“Player Settings”(播放器设置)中的一些设置,以使ARM64可用:
1.将“脚本后端”从Mono切换到ILCPP,这使我们能够:
1.在目标架构下选择“ARM64”
如果您在构建时遇到类似“NDK not found”的错误,请确保Unity已下载并安装了自己的NDK副本:
记住所有这些将使我们能够链接到这些库,而不会找不到“libmain.so“。
sbdsn5lh2#
请将以下行添加到您的string.xml
之后,将以下片段添加到您的应用级别的gradle文件中
就是这样。享受编码吧!!
fxnxkyjh3#
我libmain.so在Android-x86 64位下遇到了www.example.com问题。有一个选项,我不确定是否在所有系统上都可用,但我的系统设置中有“启用本机桥”选项。
yx2lnoni4#
您可能需要安装houdini才能在Android x86上启用本机桥:
wkyowqbh5#
这个解决方案对我很有效!!
在播放器设置中,选择ARM 64为已选中,以使ARM 64能够检查:
1.正在将“脚本后端”从Mono切换到ILCPP
1.现在选择目标架构下的ARM 64
