bugreport是什么，怎么用？
Android系统想要成为一个功能完备，生态繁荣的操作系统，那就必须提供完整的应用开发环境。而在应用开发中，app程序的调试分析是日常生产中进程会进行的工作。Android为了方便开发人员分析整个系统平台和某个app在运行一段时间之内的所有信息，专门开发了bugreport工具。这个工具使用起来十分简单，只要在终端执行（linux或者win）：
<code class="hljs avrasm has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: "Source Code Pro", monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">adb bugreport > bugreport<span class="hljs-preprocessor" style="color: rgb(68, 68, 68); box-sizing: border-box;">.txt</span></code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right: 1px solid rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul>
即可生成bugreport文件。但是有一个问题是，这个生成的文件有的时候异常庞大，能够达到15M+,想一想对于一个txt文本格式的文件内容长度达到了15M+是一个什么概念，如果使用文本工具打开查看将是一个噩梦。因此google针对android 5.0（api 21）以上的系统开发了一个叫做battery historian的分析工具，这个工具就是用来解析这个txt文本文件，然后使用web图形的形式展现出来，这样出来的效果更加人性化，更加可读。它的基本界面像下面这个样子：
目前google已经将bettery historian开源了，开源项目的地址：
https://github.com/google/battery-historian
google写了一个比较详细的说明文档，大家可以自行查阅一下。这个工具可以查看以下信息：
<code class="hljs applescript has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: "Source Code Pro", monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">BrightnessCPU <span class="hljs-property" style="box-sizing: border-box;">running</span>Charging <span class="hljs-function_start" style="box-sizing: border-box;"><span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">on</span></span>Charging statusHealthJobSchedulerKernel only uptimeLevelPackage activePartial wakelockPhone scanningPhone statePlugPluggedScreenTemperatureTop appVoltageWifi <span class="hljs-function_start" style="box-sizing: border-box;"><span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">on</span></span>Wifi <span class="hljs-property" style="box-sizing: border-box;">running</span>Wifi supplicant</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right: 1px solid rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li><li style="box-sizing: border-box; padding: 0px 5px;">6</li><li style="box-sizing: border-box; padding: 0px 5px;">7</li><li style="box-sizing: border-box; padding: 0px 5px;">8</li><li style="box-sizing: border-box; padding: 0px 5px;">9</li><li style="box-sizing: border-box; padding: 0px 5px;">10</li><li style="box-sizing: border-box; padding: 0px 5px;">11</li><li style="box-sizing: border-box; padding: 0px 5px;">12</li><li style="box-sizing: border-box; padding: 0px 5px;">13</li><li style="box-sizing: border-box; padding: 0px 5px;">14</li><li style="box-sizing: border-box; padding: 0px 5px;">15</li><li style="box-sizing: border-box; padding: 0px 5px;">16</li><li style="box-sizing: border-box; padding: 0px 5px;">17</li><li style="box-sizing: border-box; padding: 0px 5px;">18</li><li style="box-sizing: border-box; padding: 0px 5px;">19</li><li style="box-sizing: border-box; padding: 0px 5px;">20</li><li style="box-sizing: border-box; padding: 0px 5px;">21</li></ul>
数据还是比较详细的。
当然，同样的bugreport数据也可以有不同的解析和阅读方式，你如果不太喜欢google的battery historian的话，你还有别的选择，那就是选择Sony开源的ChkBugReport，这个工具提供了不同于battery historian的视角去解读bugreport文件，界面简单明了： 
这个项目的文档：
http://developer.sonymobile.com/2012/01/25/new-bugreport-analysis-tool-released-as-open-source/
开源地址首页：

这里说明一下，笔者使用过ChkBugReport这个工具，感觉很不错，最好结合google的battery historian；另外ChkBugReport这个工具还有一点bug，不过不影响使用。
bugreport的原理是什么？
下面我们简要分析一下adb bugreport运行的原理。我们知道，使用bugreport只要执行adb bugreport命令就可以了，因此我们的分析肯定是从adbd这个daemon进程开始，我们查看这个进程的代码的时候发现这里处理了bugreport选项：
adb_commandline@system/core/adb/commandline.cpp 
我们可以清楚地看到，这里判断如果附带的参数是bugreport的话，那就直接调用send_shell_command函数处理，这个函数的代码比较简单，我们就不分析了，这个函数的功能就是使用shell执行参数中的命令，因此我们这里相当于执行了bugreport命令。
在android设备中，bugreport命令存在于system/bin/目录下，这是一个可执行文件，所以我们要查看这个可执行文件实现的地方，它的实现代码在/frameworks/native/cmds/bugreport/目录下： 
我们看到，bugreport的实现是比较简单的，只有一个Android.mk和一个cpp实现代码，我们先看一下Android.mk文件： 
这里我们看到该目录下的代码会被编译成一个名字叫做bugreport的可执行文件，这就是我们想要找的。现在我们看一下bugreport.cpp文件的实现，这个文件中代码比较简单，只有一个main函数：
<code class="hljs cpp has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: "Source Code Pro", monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;">// This program will trigger the dumpstate service to start a call to</span><span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;">// dumpstate, then connect to the dumpstate local client to read the</span><span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;">// output.

1.启动dumpstate service
2. 和dumpstate service建立socket链接
3. 从socket中读取数据，并且答应到stdout中
4. 读取完成之后关闭socket，然后退出
因此，我们分析的重点需要转移到dumpstate中了。这里说明一下，前面启动dumpstate service的方法是使用系统属性来实现，这个属性的改变消息会被init进程收到，然后init进程会启动dumpstate这个服务。
dumpstate其实也是一个可执行文件，也存在于system/bin目录下。现在我们明白了，其实bugreport就是dumpstate，只是bugreport将dumpstate包装了一下而已。
现在我们需要分析一下dumpstate的实现，它的实现代码在：frameworks/native/cmds/dumpstate目录下，我们看下这个目录下的代码结构： 
这里的代码也是十分简单，只要少数的几个实现文件，其中main函数在dumpstate.c文件中，这个main函数我们这里不详细分析了，总结下它的主要工作：
1. 根据启动参数，初始化相关资源
2. 如果启动参数中带有-s的话（init启动会加上这个参数），就表示使用socket，那么就启动socket，并且在这个socket中等待链接。
3. 如果client端（也就是bugreport进程）链接成功，那就初始化所要用到的内存，并且设置优先级为较高优先级，防止被OOM干掉。
4. 然后使用vibrator震动一下（如果设备有这个硬件的话），提示用户开始截取log了
5. 调用dumpstate函数开始真正的dump工作
6. dump完成之后再次调用vibrator震动3次，提示用户dump完成。
现在我们看下dumpstate函数的实现：

1.系统属性
2./proc和/sys节点文件
3.执行shell命令获得相关输出
4.logcat输出
5.Android Framework Services信息基本使用dumpsys命令通过binder调用服务中的dump函数获得信息
这里我们需要看一下dumpsys命令的实现，这个命令也是比较简单，实现全部在main函数中：

这句来调用service的dump函数。
dumpstate会调用到所有binder中的service的dump函数，因为dumpstate函数执行了这一句：
<code class="hljs applescript has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: "Source Code Pro", monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">/* <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">the</span> full dumpsys <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">is</span> starting <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">to</span> take a long <span class="hljs-property" style="box-sizing: border-box;">time</span>, so we need <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">to</span> increase <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">its</span> <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">timeout</span>. we really need <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">to</span> do <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">the</span> timeouts <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">in</span> dumpsys itself... */run_command(<span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"DUMPSYS"</span>, <span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">60</span>, <span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"dumpsys"</span>, NULL);</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right: 1px solid rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li></ul>
直接执行dumpsys，没有参数，并且注释中也说的很清楚，就是采集所有的信息。这会执行以下service的dump函数（执行dumpsys | grep “DUMP OF SERVICE”可以看到）：

这里总结以下，上面的bugreport整体逻辑如下图描述（如果图片太小看不清，请下载图片并查看）：
adb bugreport的其他选项
bugreport本身并没有什么选项，主要是通过dumpsys等命令配合完成，详见battery historian项目主页：https://github.com/google/battery-historian，以下是个总结：
1）. 重置电池统计信息：
<code class="hljs livecodeserver has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: "Source Code Pro", monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">adb <span class="hljs-built_in" style="color: rgb(102, 0, 102); box-sizing: border-box;">shell</span> dumpsys batterystats <span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;">--reset</span></code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right: 1px solid rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul>
2）. Wakelock analysis全部wakelock信息：
<code class="hljs lasso has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: "Source Code Pro", monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">adb shell dumpsys batterystats <span class="hljs-subst" style="color: rgb(0, 0, 0); box-sizing: border-box;">--</span>enable <span class="hljs-literal" style="color: rgb(0, 102, 102); box-sizing: border-box;">full</span><span class="hljs-attribute" style="box-sizing: border-box;">-wake</span><span class="hljs-attribute" style="box-sizing: border-box;">-history</span></code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right: 1px solid rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul>
3）. Kernel trace analysis分析内核，主要分析wakeup source和wakelock activities，首先使能kernel分析：
<code class="hljs sql has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: "Source Code Pro", monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">$ adb root$ adb shell# <span class="hljs-operator" style="box-sizing: border-box;"><span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">Set</span> the events <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">to</span> trace.$ echo <span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"power:wakeup_source_activate"</span> >> /d/tracing/set_event$ echo <span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"power:wakeup_source_deactivate"</span> >> /d/tracing/set_event# The <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">default</span> trace <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">size</span> <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">for</span> most devices <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">is</span> <span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">1</span>MB, which <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">is</span> relatively low <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">and</span> might cause the logs <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">to</span> overflow.# <span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">8</span>MB <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">to</span> <span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">10</span>MB should be a decent <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">size</span> <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">for</span> <span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">5</span>-<span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">6</span> hours <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">of</span> logging.$ echo <span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">8192</span> > /d/tracing/buffer_size_kb$ echo <span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">1</span> > /d/tracing/tracing_on</span></code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right: 1px solid rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li><li style="box-sizing: border-box; padding: 0px 5px;">6</li><li style="box-sizing: border-box; padding: 0px 5px;">7</li><li style="box-sizing: border-box; padding: 0px 5px;">8</li><li style="box-sizing: border-box; padding: 0px 5px;">9</li><li style="box-sizing: border-box; padding: 0px 5px;">10</li><li style="box-sizing: border-box; padding: 0px 5px;">11</li><li style="box-sizing: border-box; padding: 0px 5px;">12</li><li style="box-sizing: border-box; padding: 0px 5px;">13</li></ul>
然后获得log：
<code class="hljs smalltalk has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: "Source Code Pro", monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><span class="hljs-char" style="box-sizing: border-box;">$ </span>echo <span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">0</span> > /d/tracing/tracing_on<span class="hljs-char" style="box-sizing: border-box;">$ </span>adb pull /d/tracing/trace <some path># <span class="hljs-class" style="box-sizing: border-box; color: rgb(102, 0, 102);">Take</span> a bug report at this time.<span class="hljs-char" style="box-sizing: border-box;">$ </span>adb bugreport > bugreport.txt</code>
