Android java.lang.IllegalStateException:全局数据库持有者未初始化。确保在访问数据库之前调用FlowManager.init（）？

如何解决这个问题 昨天应用程序运行正常，今天我运行相同的代码，在启动屏幕活动中出现运行时错误

E/AndroidRuntime: FATAL EXCEPTION: main
                  Process: com.planfisheye.fisheye, PID: 11217
                  java.lang.IllegalStateException: The global database holder is not initialized. Ensure you call FlowManager.init() before accessing the database.

尝试在项目的应用程序类中初始化数据库。

您的错误日志就是您的解决方案。它清楚地说明了你需要做什么。但它以前没有显示，为什么现在显示？
