Android 三星S4上的蓝牙崩溃

我正在运行一个带有BLE扫描的应用程序。在三星S4上，一段时间后，或者如果周围有10个以上的信标，我会看到以下错误：

即使我的应用程序未运行，也会发生此问题。如果我打开蓝牙，周围有20多个蓝牙设备，就会出现错误，手机会变得非常慢。

有任何解决此问题的建议吗？

您能否包含一些日志消息，显示您的应用程序在何处拨打电话？查看这些和这些之间的交错，以及（）中的进程ID是否匹配，这将非常有用，表明这是在应用程序中运行的系统库代码还是在系统进程中运行的系统代码（或者可能是独立的、仅巧合相关的代码）。我已经添加了完整的日志，但即使在应用程序未运行的情况下也会出现错误。那么，它可能与您的项目无关。
