问题：
Android Studio应用程序在没有调试器的情况下启动时会崩溃
段干华皓
从昨天开始，当我在没有调试器的情况下启动应用程序时，它就会挂起。当我调试应用程序时，一切正常。我不知道我是不是应该把代码贴出来我觉得太多了。我正在使用Google Maps API。

我是Quarkus新手，正在使用Eclipse和Quarkus插件。 无论我是手动使用启动还是使用Eclipse夸克启动配置，应用程序似乎总是在运行测试。 我看到了类似的东西 有一段时间什么都没发生，直到我看到Quarkus标志、我的日志消息等。 也许我还没有仔细阅读文档，但我发现没有配置来关闭它并直接在开发模式下启动应用程序。 有人能帮我吗？

问题内容： 通常，要将调试器附加到正在运行的jvm，您需要使用以下参数启动jvm： 现在，如果我要调试不是在调试模式下启动的进程，该怎么办？ 当生产系统（即在没有调试args的情况下启动）显示“随机”（我用宽松的术语）错误时，就会出现这种情况。因此，我无法使用适当的参数重新启动jvm，因为没人知道如何再次再现该错误。在这种情况下是否不可能附加到JVM？ 只是为了澄清，除非将它们以调试方式启动，否则

我复制了gRPC helloworld示例中粘贴的gRPC服务器。 它开始侦听指定端口中的RPC，但当我使用复制粘贴的客户端调用RPC时，它会崩溃，出现“中止（内核转储）”，在客户端收到错误消息“Endpoint read failed”。 我尝试通过在RPC函数实现中包含一些输出语句来调试它，但执行从未达到目的。 没有其他错误消息，是否有一些标志使故障更详细，以便调试？
