使用IL2CPP的Firebase Unity3D Android构建：libApp.so，错误：无法加载库

Question

我查看了消息传递示例应用程序（https://github.com/firebase/quickstart-unity/tree/master/messaging/testapp），并尝试为Android平台构建。使用脚本后端选项是Mono2x，一切都在设备上运行正常，但是使用选项IL2CPP，Android logcat在Firebase初始化方法上显示以下错误：

11-14 10:31:17.233: E/Unity(5088): Couldn't open /data/app-lib/com.firebase.testfcm-1/libApp.so, error: Cannot load library:

有没有人有同样的问题？

谢谢。

Answer 1

我遇到了同样的问题。

解压缩apk，发现libApp.so不在apk文件中。

我用unity来导出gradle项目。

最后，我发现导出的gradle项目不包含lib文件夹中的aars。我添加在build.gradle中包含aar并解决此问题。
