[android]android自动化测试十一之代码覆盖率报告EMMA

以下代码时监听测试程序结束后将Emma测试报告写入到虚拟机上，然后可以使用adb pull命令发送至硬盘上，这里需要测试程序集成Emma jar包，并需要修改ant build文件。

定义finish接口

package com.example.instrumentation;/** * Listen for an Activity to finish and invokes {@link #onActivityFinished()} when this happens. *  * @author diego * */public interface FinishListener {        /**         * Invoked when the Activity finishes.         */        void onActivityFinished();}

修改ant build.xml文件

 <!-- It only instruments class files, not any external libs -->            <emma enabled="true">               <instr verbosity="${verbosity}"                               mode="overwrite"                               instrpath="${out.absolute.dir}/classes"                               outdir="${out.absolute.dir}/classes">                    <!-- DTM: 2011-12-23: added filter for R -->                     <filter excludes="*.R" />                     <filter excludes="*.R$*" />                </instr>                <!-- TODO: exclusion filters on R*.class and allowing custom exclusion from                             user defined file --></emma>
