想做个蓝牙app， 但是现在 搜索出 蓝牙设备后， 点击设备， 连接不上。
错误的地方觉得主要有：
第一：java.lang.SecurityException: Permission Denial: get/set setting for user asks to run as user -2 but is calling from user 0; this requires android.permission.INTERACT_ACROSS_USERS_FULL
和
第二：
11-13 05:06:33.836: D/AbsListView(20856): unregisterIRListener() is called
11-13 05:06:33.836: D/AbsListView(20856): unregisterIRListener() is called
对于第一个错误： 在androidmanifest 已经声明了：
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.INTERACT_ACROSS_USERS_FULL"/>
为什么还是会报错呢？
对于第二处 错误log， 应该怎么处理呢？ 还有别的地方错误吗？
请会的朋友帮忙回复，先谢谢啦

------解决思路----------------------
debug到哪句话会报错误
------解决思路----------------------
第一：
Permission Denial: get/set setting for user asks to run as user -2 but is calling from user 0
引用自 http://www.tuicool.com/articles/Q7RjAr
log中直接给出提示，需要加一个权限INTERACT_ACROSS_USERS_FULL，这个权限时API17新引入的，目的在于允许不同用户的应用之间可以产生交互。可是加上去之后发现，还不是无法调起浏览器，而且log依然提示需要权限INTERACT_ACROSS_USERS_FULL，很是奇怪，于是继续分析。
首先说明一下Linux中的pid和uid，以及android扩展的userSerialNumber。pid是Process的标识，用于系统对进程的控制，从API层面看就是用于Process.killProcess()和Process.sendSignal()；uid在Linux系统中是用来标识用户的，而在android将uid视为app的标识id，用于"sandbox"安全模型，即用于app权限控制；而对于API17引入的多用户支持（目前只支持平板），uid已经被占用，只好新引入userSerialNumber来标识用户。
回到刚才的问题，log中告知startActivity时运行用户标识为-2，而调用却是由用户标识0发起，导致拒绝执行。用这句话搜索，发现在Google开发者网站中有相关的issue，链接如下： https://code.google.com/p/android/issues/detail?id=39801 （打不开可以把https改为http）。结合官方的回答，问题原因如下：由于被卸载，C端进程监听到目录被删除，立即执行am命令，此时将会默认以USER_CURRENT的身份执行，由于API17中ActivityManagerService.handleIncomingUser()会校验userSerialNumber，发现用户标识不匹配，导致权限校验失败——这也说明了权限的影响范围仅限于Java端的进程，对于fork()出来的C端进程来说，并不继承父进程在Android中声明的权限。
解决方案：增加处理分支，若API>=17，将userSerialNumber传递给C端进程，然后在am命令中带上参数--user userSerialNumber即可。
问题2：
八成是控件用法的有问题。最好多贴一下 newListView 相关的代码。
------解决思路----------------------
tmp = device.createInsecureRfcommSocketToServiceRecord(uuid);
目测这个uuid 有问题吧。
我没搞过蓝牙相关的东西，不了具体怎么改， 楼主参考之前的链接看看人家怎么处理，再改呗。
问题二，我去查了一下android 4.4 和5.L源码，貌似都没有 unregisterIRListener 这个LOG相关的代码。
要是源码改过的话，具体代表啥意思就不知道了。
看样子这个仅仅只是输出debug的信息而已，对APP没影响吧。
另外你的代码，我没看出有啥问题。
