在托管回调的类中调用媒体播放器的 play 方法后添加 Thread.currentThread().join(); 。它会以某种方式保持线程运行，防止在出现任何 native 库错误时由于可执行逻辑结束而停止执行。

经过多次实验或反复试验后，我发现了这一点。

需要其他东西来保持应用程序运行，否则即使在处理流时 native 代码中出现一个错误也会杀死整个应用程序。我获取自定义渲染器使用示例的实际代码是打开一个 jwt 框架，该框架使应用程序保持打开状态。我删除了它，因为我不需要显示任何东西。但是，现在我开始遇到问题了。正在运行的线程/类没有其他工作了，任何源自 native lib 的错误都会中断连接(专家可能会在此处使用更好的术语)，因此程序将关闭，作为返回，JNI 将触发回调对象被垃圾收集。

我使用的是Thread.currentThread().join();，但在创建实例后在类之外，因此对托管渲染/处理数据的回调的类没有任何影响。

更多地考虑 jwt Frame 可能在做什么，我将其删除并替换为构造函数内的 Thread.currentThread().join(); ，瞧，它开始完美工作。
