android6.0 蓝牙遇到com.android.bluetooth进程终止

6军临天下6 2015-11-13 10:18:42
Hi,最近刚接触安卓6.0蓝牙开发,遇到com.android.bluetooth 进程终止,请问我应该怎么从log分析,定位到问题原因或者异常代码位置。

这种情况出现,意味着你的蓝牙主进程crash了。Android系统会生成详细的crash信息。
第一个是在logcat中搜索AndroidRuntime,看是否有com.android.bluetooth的报错。AndroidRuntime是Java层的代码异常所打印的错误信息,例如空指针引用等。
第二个是在你的开发板的/data/tombstones目录下,查看tombstone文件。一般C/C++层代码出错,都会生成tombstone文件。每一个出错生成一个tombstone文件。所以可能会在该目录下看到多个。挨个打开查看,可以看到crash的地方,运气好还能看到函数栈,清晰地看到那个文件哪个函数出错了。如果看不到函数栈,在tombstone文件最下面还有crash时的logcat信息,可以从这里找找线索,看看哪里导致了crash。
