我尝试使用 Diego 在以下帖子中的说明设置我的项目：http: //dtmilano.blogspot.com/2011/11/obtaining-code-coverage-of-running.html

在尝试使用启动应用程序时adb shell am instrument -e coverage true -w ...

我得到以下错误：

E/Trace   ( 3989): error opening trace file: No such file or directory (2)

我在构建路径中包含了 emma.jar 并将其部署在应用程序中，但出现以下错误：

知道如何解决这个问题吗？

谢谢！

看来您应该执行以下命令：

“蚂蚁仪器”

因为你有这样的错误信息：****找不到方法 com.vladium.emma.rt.RT.r

下面的链接帮助我解决了这个问题。我正在使用添加以下依赖项：

在 app 文件夹中的 build.gradle 文件中添加了以下依赖项。

compile group: 'org.jruby', name: 'jruby', version: '1.4.1'

以及项目文件夹中存在的 build.gradle 文件中的以下依赖项。

maven {
            url "https://repo1.maven.org/maven2/"
        }

从以下链接中选择您的依赖项：http: //snacktrace.com/artifacts/org.jruby/jruby/1.4.1/com.vladium.emma.rt.RT
