<title><![CDATA[Android使用Google Breakpad进行崩溃日志管理]]></title>

<content type="html"><![CDATA[<ul>
<li>开发过程中，最担心的问题就是程序崩溃，而且还不知道崩溃的原因，现在使用Google Breakpad来跟踪崩溃的位置，非常方便；由于目前使用Mac系统开发，Google Breadpad处理Android崩溃日志时需要Linux环境，借助 vagrant 可以非常方便地在Mac使用Ubuntu环境。</li>
</ul>
<figure class="highlight c++"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br><span class="line">5</span><br><span class="line">6</span><br><span class="line">7</span><br><span class="line">8</span><br></pre></td><td class="code"><pre><span class="line">$ varant ssh</span><br><span class="line">$ cd /vagrant</span><br><span class="line">$ sudo apt-get update</span><br><span class="line">$ sudo apt-get install build-essential</span><br><span class="line">$ svn checkout http:<span class="comment">//google-breakpad.googlecode.com/svn/trunk/ google-breakpad-read-only</span></span><br><span class="line">$ cd google-breakpad-read-only</span><br><span class="line">$ ./configure</span><br><span class="line">$ make</span><br></pre></td></tr></table></figure>
<p>执行完上面的命令将会在<code>google-breakpad-read-only/src/processor</code>目录下生成<code>minidump_stackwalk</code>工具，用于导出crash log.<br><code>google-breakpad-read-only/src/tools/linux/dump_syms</code>目录下生成 dump_syms工具，用于导出符号文件。<br><code>google-breakpad-read-only/src/client/linux</code> 目录下生成 libbreakpad_client.a。</p>
<a id="more"></a>
<ul>
<li>如果编译遇到 <code>“cc1plus: warnings being treated as errors“</code>错误，请将<code>google-breakpad-read-only/Makefile</code>文件中<code>"* -Werror* "</code>删除，重新编译。</li>
<li>如果make的时候遇到 “/lib64/libc.so.6: version `GLIBC_2.14’ not found “错误，说明 glibc 没有安装，安装方法请移步：<a href="http://my.oschina.net/zhangxu0512/blog/262275" target="_blank" rel="external">http://my.oschina.net/zhangxu0512/blog/262275</a></li>

<li>什么是热更新？</li>
</ul>
<p><code>客户端启动时，主动请求服务端检查版本号，并更新资源到本地。</code></p>
<ul>
<li>应用场景：<ul>
<li>情况一：客户端已经发布了，但突然发现有个比较严重的bug需要修复。这时需要更新客户端的代码（Lua代码）。</li>
<li>情况二：情人节到了，需要搞个活动，在客户端中营造一个节日氛围。这时，需要更新客户端资源或增加一些功能。</li>
</ul>
</li>
<li>好处：<br><code>不需要重新打包和提交应用到市场等待审核。</code></li>
</ul>

<li>加载Lua脚本解析引擎</li>
<li>以Native API方式调用引擎接口</li>
</ol>
<ul>
<li>直接以JNI方式调用Lua解析引擎的接口十分麻烦，开源项目<a href="https://github.com/mkottman/AndroLua" target="_blank" rel="external">LuaJava</a>对这些JNI接口进行了很好的封装，它是一个包含了LuaJava的Android平台的Lua解析器，它提供一系列映射到Lua C实现函数的Java接口。</li>

<li>.lua文件可存放在assets、raw文件夹；</li>
<li>提供给lua的回调必须是public，否则lua调不到；</li>
<li>“.”是用来调用类的方法或变量（静态方法），而“:”是用来调用对象的方法。</li>
