java - Btld 在应用程序停止后消耗资源？

转载作者：行者123 更新时间：2023-11-29 09:20:52

我正在编写一个基于蓝牙的小型串行控制程序来与微 Controller 板上的串行 BT 调制解调器通信。它主要基于Android BluetoothChat 示例程序。

当我第一次从 Eclipse 运行该程序时，它安装并运行得很好。但是，我发现有一些问题，当我更改程序并重新运行它时，手机运行速度会非常慢。这在 Activity 管理器中报告为 btld 消耗了 94% 的 CPU 资源。此时唯一的解决办法是取出电池并重启手机。我曾尝试参加 Activity 并停止任何与 BT 相关的 Activity ，但这无济于事。

此外，我刚刚使用 Android 的标准 BluetoothChat 程序对其进行了测试，它做同样的事情。它不特定于我的附加代码。

我也相信，经过一些实验后，问题会在应用程序停止时发生，这会在您强制停止它或安装新包时发生。它变得非常烦人，因为每次它发生时，我都必须重新启动或取出电池 - 这可能需要 5 分钟的过程。根本不适合调试。

我在 HTC Inspire 4G (2.2) 上运行它，使用 Eclipse (Java) 等。

我的问题是:

如何阻止 btld 消耗资源？
更重要的是，是什么导致了这种情况发生，我是否应该在我的代码中做一些不同的事情？

有关更多信息，我在程序关闭然后关闭 BT 期间获得了 DDMS 的输出。看起来 DVM 很难停止 BT 服务。我删除了很多调试消息，除非它们与蓝牙等有关。

最佳答案

我发现一个可行的解决方案(适用于三星 galaxy mini)——这对用户来说非常不友好，而且“设计”不好(但 broadcom 固件错误无论如何都不是好的“设计”)——但总比让用户的手机卡住 - 完成后关闭蓝牙:

在我的 onDestroy() 和 onBackPressed() 中——我调用了我的 cleanup() 函数，它具有如下内容:

if(mBluetoothAdapter != null)
{           
mBluetoothAdapter.disable();            
}    
mBluetoothAdapter = null;

注意:在官方 android sdk 的 bluetooth_chat 示例应用程序也发生 bt 使用后，同一部手机“卡住”(在使用 broadcom bt 堆栈的三星 galaxy 上)——同样的问题——所以这显然不是编程“设计”问题。
