有两个项目：

我的项目

和

库项目

我已经在Android studio中导出了

现在，我将这个

jar

放入

myproject

中，以允许将其用作库

成功清除并同步渐变后<代码>我的项目可以正确理解

jar

库中的类

但在启动之后，它仍然会崩溃，并在与

jar库相关的异常下运行
我不知道为什么
知道的人请告诉我如何修复
谢谢,
p/s：实际上，我试图将jar库发布到maven，所以在发布之前需要进行测试
如果我没有在manifest.xml中声明activityCustomCamera

cutom摄像头模块已安装missing@war_Hero：你检查了我的项目结构？您可以看到包装摄像头模块没有丢失。如何修复它？转到文件-->项目结构-->应用程序-->依赖项，检查是否可以看到它们（如果不知道）me@war_Hero：请再次检查图像。实际上，我可以在我的项目中调用并集成Jar库中的类。您的库有资源吗？如果是这样的话，把它建成一个罐子不是一个好主意。
