游戏加载期间崩溃：理解“JNI 关键锁持有......”

Question

我的 LibGDX And​​roid 游戏在加载过程中随机崩溃。我想这与 Android 由于主线程中长时间运行的任务或内存问题而杀死我的应用程序有关。

在这方面，我想了解日志中这些行的含义：

03-12 10:00:18.444  5522  5540 W com.asdfasdf: JNI critical lock held for 38.485ms on Thread[13,tid=5540,Runnable,Thread*=0x9d711000,peer=0xa3e40000,"GLThread 248"]

03-12 10:00:20.700  5522  5540 W com.asdfasdf: JNI critical lock held for 49.684ms on Thread[13,tid=5540,Runnable,Thread*=0x9d711000,peer=0xa3e40000,"GLThread 248"]

我找不到关于这个主题的太多内容。日志行被归类为警告，但我不太确定他们想告诉我什么。

然后游戏以这些台词结束并为我提供一个墓碑（万岁..）：

您的内部库之一存在内存密集型操作。进行跟踪以查找哪个库正在使用内存进行读/写操作或后台任务。要解决该问题，您可能需要增加缓冲区并添加一些检查以防止分配过多的内存。
