Android上如何使用

1.在自定义Application中初始化，为了更早的修复应用中的bug。

<code class="language-Java hljs java 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:#0088;box-sizing: border-box;">package</span> com.euler.andfix;<span class="hljs-keyword" style="color:#0088;box-sizing: border-box;">import</span> android.app.Application;<span class="hljs-keyword" style="color:#0088;box-sizing: border-box;">import</span> com.alipay.euler.andfix.patch.PatchManager;<span class="hljs-javadoc" style="color:#8800;box-sizing: border-box;">/*** MainApplication 2015-11-12 下午2:07:11* *<span class="hljs-javadoctag" style="color:#66066;box-sizing: border-box;"> @author</span> 乔晓松 965266509@qq.com*/</span>
<span class="hljs-keyword" style="color:#0088;box-sizing: border-box;">public</span> <span class="hljs-class" style="box-sizing: border-box;"><span class="hljs-keyword" style="color:#0088;box-sizing: border-box;">class</span> <span class="hljs-title" style="color:#66066;box-sizing: border-box;">MainApplication</span> <span class="hljs-keyword" style="color:#0088;box-sizing: border-box;">extends</span> <span class="hljs-title" style="color:#66066;box-sizing: border-box;">Application</span> {</span><span class="hljs-keyword" style="color:#0088;box-sizing: border-box;">public</span> PatchManager mPatchManager;<span class="hljs-annotation" style="color:#9b859d;box-sizing: border-box;">@Override</span><span class="hljs-keyword" style="color:#0088;box-sizing: border-box;">public</span> <span class="hljs-keyword" style="color:#0088;box-sizing: border-box;">void</span> <span class="hljs-title" style="box-sizing: border-box;">onCreate</span>() {<span class="hljs-keyword" style="color:#0088;box-sizing: border-box;">super</span>.onCreate();<span class="hljs-comment" style="color:#8800;box-sizing: border-box;">// 初始化patch管理类</span>mPatchManager = <span class="hljs-keyword" style="color:#0088;box-sizing: border-box;">new</span> PatchManager(<span class="hljs-keyword" style="color:#0088;box-sizing: border-box;">this</span>);<span class="hljs-comment" style="color:#8800;box-sizing: border-box;">// 初始化patch版本</span>mPatchManager.init(<span class="hljs-string" style="color:#0880;box-sizing: border-box;">"1.0"</span>);<span class="hljs-comment" style="color:#8800;box-sizing: border-box;">// 加载已经添加到PatchManager中的patch</span>mPatchManager.loadPatch();}
}
</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-width: 1px; border-right-style: solid; border-right-color: 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><li style="box-sizing: border-box; padding: 0px 5px;">22</li><li style="box-sizing: border-box; padding: 0px 5px;">23</li><li style="box-sizing: border-box; padding: 0px 5px;">24</li><li style="box-sizing: border-box; padding: 0px 5px;">25</li><li style="box-sizing: border-box; padding: 0px 5px;">26</li><li style="box-sizing: border-box; padding: 0px 5px;">27</li></ul>

2.如果有新的补丁需要修复，下载完成后，进行以下操作

<code class="hljs cs 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:#8800;box-sizing: border-box;">//添加patch，只需指定patch的路径即可，补丁会立即生效</span>
mPatchManager.addPatch(path);</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-width: 1px; border-right-style: solid; border-right-color: 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></ul>

3.当apk版本升级，需要把之前patch文件的删除，需要以下操作

<code class="hljs cs 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:#8800;box-sizing: border-box;">//删除所有已加载的patch文件</span>
mPatchManager.removeAllPatch();</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-width: 1px; border-right-style: solid; border-right-color: 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></ul>

patch文件的生成

使用工具：apkpatch-1.0.3
原理：根据两个apk包，生成一个差异文件，就是所谓的补丁文件即patch文件。

<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;">命令 : apkpatch<span class="hljs-built_in" style="color:#66066;box-sizing: border-box;">.</span>bat <span class="hljs-attribute" style="box-sizing: border-box;">-f</span> <span class="hljs-literal" style="color:#06666;box-sizing: border-box;">new</span><span class="hljs-built_in" style="color:#66066;box-sizing: border-box;">.</span>apk <span class="hljs-attribute" style="box-sizing: border-box;">-t</span> old<span class="hljs-built_in" style="color:#66066;box-sizing: border-box;">.</span>apk <span class="hljs-attribute" style="box-sizing: border-box;">-o</span> output1 <span class="hljs-attribute" style="box-sizing: border-box;">-k</span> debug<span class="hljs-built_in" style="color:#66066;box-sizing: border-box;">.</span>keystore <span class="hljs-attribute" style="box-sizing: border-box;">-p</span> android <span class="hljs-attribute" style="box-sizing: border-box;">-a</span> androiddebugkey <span class="hljs-attribute" style="box-sizing: border-box;">-e</span> android<span class="hljs-attribute" style="box-sizing: border-box;">-f</span> <span class="hljs-subst" style="color:#000000;box-sizing: border-box;"><</span><span class="hljs-literal" style="color:#06666;box-sizing: border-box;">new</span><span class="hljs-built_in" style="color:#66066;box-sizing: border-box;">.</span>apk<span class="hljs-subst" style="color:#000000;box-sizing: border-box;">></span> ：新版本

执行完命令，就会在输出目录中输出.apatch文件:

new-c293df7dbc23f11214fdd020ea78d3b8.apatch：就是patch文件。

.apatch文件根目录内容：
META_INF文件下内容：
PATCH.MF文件内容：注：Patch-Classes就是改动过的class.

客户端请求服务器接口(api)，服务器根据用户传递的数据分析是否有需要修复的bug。
如果有bug需要修复，就下载服务器指定的.apatch文件的链接，下载完后及时加载并修复，使用addpatch(path)方法，补丁会立即生效。

在Android Studio使用

maven dependency:

<code class="hljs xml 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-tag" style="color:#06666;box-sizing: border-box;"><<span class="hljs-title" style="color:#0088;box-sizing: border-box;">dependency</span>></span><span class="hljs-tag" style="color:#06666;box-sizing: border-box;"><<span class="hljs-title" style="color:#0088;box-sizing: border-box;">groupId</span>></span>com.alipay.euler<span class="hljs-tag" style="color:#06666;box-sizing: border-box;"></<span class="hljs-title" style="color:#0088;box-sizing: border-box;">groupId</span>></span><span class="hljs-tag" style="color:#06666;box-sizing: border-box;"><<span class="hljs-title" style="color:#0088;box-sizing: border-box;">artifactId</span>></span>andfix<span class="hljs-tag" style="color:#06666;box-sizing: border-box;"></<span class="hljs-title" style="color:#0088;box-sizing: border-box;">artifactId</span>></span><span class="hljs-tag" style="color:#06666;box-sizing: border-box;"><<span class="hljs-title" style="color:#0088;box-sizing: border-box;">version</span>></span>0.3.1<span class="hljs-tag" style="color:#06666;box-sizing: border-box;"></<span class="hljs-title" style="color:#0088;box-sizing: border-box;">version</span>></span><span class="hljs-tag" style="color:#06666;box-sizing: border-box;"><<span class="hljs-title" style="color:#0088;box-sizing: border-box;">type</span>></span>aar<span class="hljs-tag" style="color:#06666;box-sizing: border-box;"></<span class="hljs-title" style="color:#0088;box-sizing: border-box;">type</span>></span>
<span class="hljs-tag" style="color:#06666;box-sizing: border-box;"></<span class="hljs-title" style="color:#0088;box-sizing: border-box;">dependency</span>></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-width: 1px; border-right-style: solid; border-right-color: 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></ul>

or gradle dependency:

<code class="hljs nginx 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-title" style="color:#0088;box-sizing: border-box;">dependencies</span> {<span class="hljs-title" style="color:#0088;box-sizing: border-box;">compile</span> <span class="hljs-string" style="color:#0880;box-sizing: border-box;">'com.alipay.euler:andfix:0.3.1<span class="hljs-variable" style="color:#66066;box-sizing: border-box;">@aar</span>'</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-width: 1px; border-right-style: solid; border-right-color: 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></ul>

在Eclipse使用

把Java层的代码引入到你的工程，配置Ndk开发环境并把jni Native代码添加进来。

代码混淆(ProGuard)

<code class="hljs scala 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;">-keep <span class="hljs-class" style="box-sizing: border-box;"><span class="hljs-keyword" style="color:#0088;box-sizing: border-box;">class</span> * <span class="hljs-keyword" style="color:#0088;box-sizing: border-box;">extends</span> <span class="hljs-title" style="color:#66066;box-sizing: border-box;">java</span>.<span class="hljs-title" style="color:#66066;box-sizing: border-box;">lang</span>.<span class="hljs-title" style="color:#66066;box-sizing: border-box;">annotation</span>.<span class="hljs-title" style="color:#66066;box-sizing: border-box;">Annotation</span></span>
-keepclasseswithmembernames <span class="hljs-class" style="box-sizing: border-box;"><span class="hljs-keyword" style="color:#0088;box-sizing: border-box;">class</span> * {</span>native <methods>;
}</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-width: 1px; border-right-style: solid; border-right-color: 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>
