我在Nexus 4和Nexus 5上看到了此问题。蓝牙已意外打开。可以关闭它，但是一分钟后会回来。
到处搜寻，看来这可能是由于应用程式行为不当所致，但似乎找不到找到哪个应用程式的好方法。
有没有办法找出什么原因一直导致蓝牙重新激活？
如果有什么用，我在禁用蓝牙后捕获了一些adb输出。
禁用时：

@Rushnosh，是的，这是两台设备上的现货Google Android。稍后我将进行内存转储，并将从中找到的内容添加到问题中。

好的，如果可能的话，还有Andriod构建版本吗？

为了回答一些问题，我有Android 4.4.4，构建KTU84P。Logitech键盘距离现在只有几公里，因此，除非我真的低估了蓝牙的功能，否则应该不会造成问题。（Nexus 5也从未见过Logitech）。另外-谢谢您到目前为止的时间...非常感谢！

抱歉，昨晚时间用完了。我重新启动，现在问题消失了！这意味着我们没有得到什么原因的答案。如果/问题再次出现，我将在电话上进行测试。感谢您的指导！

adb shell dumpsys meminfo..也可能是您在手机上安装的软件包，这可能是罪魁祸首。仅供参考-我在带有备用ROM的Nexus 5-植根手机上进行了相同的测试。一切都为我工作..但是，我发现此日志行很有趣，当我停止蓝牙服务时状态从13-> 10改变了–D/BluetoothManagerService( 1683): Bluetooth State Change Intent: 13 -> 10
