单元测试覆盖率报告

Question

我正在尝试获取单元测试的覆盖率报告，但构建总是失败。

我正在使用本教程（blog.pboos）一步一步。

一切都很顺利，除了我运行蚂蚁覆盖的最后一步。

这就是我得到的：

知道出了什么问题吗？难道是我的Android SDK Tools文件夹里有空格？

添加我的测试项目的构建文件。也许有帮助？

<?xml version="1.0" encoding="UTF-8"?>
<project name="MyWalletActivityTest" default="help">

<!-- The local.properties file is created and updated by the 'android'
     tool.
     It contains the path to the SDK. It should *NOT* be checked into
     Version Control Systems. -->
    <property file="local.properties" />

    <!-- The build.properties file can be created by you and is never touched
         by the 'android' tool. This is the place to change some of the
         default property values used by the Ant rules.
         Here are some properties you may want to change/update:

         source.dir
             The name of the source directory. Default is 'src'.
         out.dir
             The name of the output directory. Default is 'bin'.

         Properties related to the SDK location or the project target should
         be updated using the 'android' tool with the 'update' action.

         This file is an integral part of the build system for your
         application and should be checked into Version Control Systems.

         -->
    <property file="build.properties" />

    <!-- The default.properties file is created and updated by the 'android'
         tool, as well as ADT.

         application and should be checked into Version Control Systems. -->

    <import file="${sdk.dir}/tools/ant/pre_setup.xml" />


<!-- extension targets. Uncomment the ones where you want to do custom work
     in between standard targets -->
<!--
    <target name="-pre-build">

    <target name="-pre-compile">

    [This is typically used for code obfuscation.
     Compiled code location: ${out.classes.absolute.dir}
     If this is not done in place, override ${out.dex.input.absolute.dir}]
    <target name="-post-compile">
    </target>
-->

    <!-- Execute the Android Setup task that will setup some properties
         specific to the target, and import the build rules files.

         The rules file is imported from
            <SDK>/tools/ant/
         Depending on the project type it can be either:
         - main_rules.xml
         - lib_rules.xml
         - test_rules.xml

         To customize existing targets, there are two options:
         - Customize only one target:
             - copy/paste the target into this file, *before* the
               <setup> task.
             - customize it to your needs.
         - Customize the whole script.
             - copy/paste the content of the rules files (minus the top node)
               into this file, *after* the <setup> task
             - disable the import of the rules by changing the setup task
               below to <setup import="false" />.
             - customize to your needs.

    <setup />

看起来 ant 在 sdk 目录方面遇到了问题。尝试在不包含任何空格的路径中重新安装 android sdk（所以永远不要“程序文件”:)）。

您收到错误“SDK 此时出现意外”。因为很可能你的android sdk路径是这样的：.../blabla SDK/...（SDK之前有一个空格）。
