Android Aidl 爱之初体验？

   <p>从前有个山 山里有个庙 庙里有个和尚 。。。。。一年过去了。老和尚跟小和尚说，孩子时候下去见母老虎了，山下的女人是老虎，师傅有一个要求您要学会aidl，当时小和尚一听懵逼了，what is this？这时老和尚摸着小和尚的头说:”学会aidl你就能下山了，遇到母老虎就可以跟我通信，师傅就马上下山救您了“，</p>    <p>遇见了不要慌，就这样小和尚很不开心，因为马上要离开师傅了，不开心，宝宝不开心嘛，但是师傅掏出一本宝典 焕名”“aidl之远程助攻母老虎72式”，小和尚拿着这本宝典开开心心的下山了，就这样十年过去了，小和尚并没有看到很多母老虎，他这时又想起师傅的话，默默的流泪，我是不是找了个假师傅，好尴尬呢？好了下面直接练习宝典！开大招！</p>    <pre>  <code class="language-java">Soeasy！</code></pre>    <p><strong>首先看第一招:入门式</strong></p>    <p style="text-align:center"><img src="https://simg.open-open.com/show/c7dd10e81f870cebc3f716ce34965bbb.gif"></p>    <p><strong>第二招：惑骗式</strong></p>    <p>先给大佬们上个图</p>    <p style="text-align:center"><img src="https://simg.open-open.com/show/9432a12b6fa3298df3e6ba2796f17850.png"></p>    <p><strong>第三招 ：进攻式</strong></p>    <ol>     <li>首先在src目录下创建一个aidl目录</li>     <li>创建一个IRemoteService.aidl文件</li>     <li>支持的数据类型 aidl支持的参数类型有int long boolean float double String</li>    </ol>    <p><strong>第四招：招虎式</strong></p>    <p>这里创建一个方法进行通信</p>    <p>String baseAidl();</p>    <p><strong>第五招:训母式</strong></p>    <p>1、这里需要创建一个RemoteService类</p>    <p>2、然后绑定服务类</p>    <p>3、创建一个Stub抽象类</p>    <p>4、在清单文件AndroidMainfest.xml中注册 需要注意5.0以上系统需要设置包名 acton Name等</p>    <p>全部代码如下</p>    <pre>  <code class="language-java">package com.example.arial.dgamedetail.service;
