无法解析符号'AndroidJUnit4“ [英] Cannot resolve symbol 'AndroidJUnit4'

问题描述

很显然，我需要正确的导入说明书来解决这个问题。按照文档的 AndroidJUnit4 < /一>，这应该是

 进口android.support.test.runner.AndroidJUnit4;
 

当我做到这一点，在红色的机器人工作室的亮点亚军并抱怨无法解析符号'跑步'。

背景

我按照在Android开发者网站上的教程设立了这一点使用用户界面的Automator 测试。我遇到的第一个问题是， com.android.support:support-v4:22.2.0 和 com.android.support.test：亚军： 0.2 取决于不同版本的 com.android.support:support-annotations 的。我跟着从这款Android bug报告并添加以下为 allprojects 我的项目的 build.gradle ：

configurations.all {         resolutionStrategy.forcecom.android.support:support-annotations:22.1.0     }

这解决了眼前的错误，但我怀疑它导致我国目前存在的问题。有没有人有关于如何解决这个问题有什么建议？

解决方案

我发现的此处有测试支持库比我用的是较新的版本：

 相关性{
    androidTestCompilecom.android.support.test：亚军：0.3
    androidTestCompilecom.android.support.test：规则：0.3
    androidTestCompilecom.android.support.test.uiautomator：uiautomator-V18：2.1.1
}
 

在特定的，亚军0.3版似乎解决了依赖问题，我刚才遇到的，使这个问题完全没有实际意义。

Obviously I need the correct import statment to solve this problem. According to the docs for AndroidJUnit4, this should be

import android.support.test.runner.AndroidJUnit4;

When I do that, Android Studio highlights runner in red and complains "Cannot resolve symbol 'runner'".

Background

I got to this point by following the tutorials on the Android Developer site for setting up tests using UI Automator. The first problem I encountered was that com.android.support:support-v4:22.2.0 and com.android.support.test:runner:0.2 depend on different versions of com.android.support:support-annotations. I followed the suggestions from this Android bug report and added the following to allprojects in my project's build.gradle:

configurations.all { resolutionStrategy.force 'com.android.support:support-annotations:22.1.0' }

This solved the immediate error, but I suspect it lead to my current problems. Does anyone have any suggestions about how to fix this?

解决方案

I found here that there are newer versions of the Testing Support Library than what I was using:

dependencies {
    androidTestCompile 'com.android.support.test:runner:0.3'
    androidTestCompile 'com.android.support.test:rules:0.3'
    androidTestCompile 'com.android.support.test.uiautomator:uiautomator-v18:2.1.1'
}

In particular, runner version 0.3 seems to solve the dependency problems I encountered earlier and makes this question completely moot.
