无法解析符号AndroidJUnit4

我正在尝试为我的应用添加loginfacebook。但是,当我添加执行此操作所需的存储库时。它导致了错误。AndroidJUnit4现在无法解析。

package com.example.user.enyatravelbataan;

import android.content.Context;

import android.support.test.InstrumentationRegistry;

import android.support.test.runner.AndroidJUnit4;

import org.junit.Test;

import org.junit.runner.RunWith;

import static junit.framework.Assert.assertEquals;

import static org.junit.Assert.*;

/**

* Instrumentation test, which will execute on an Android device.

*

* @see <a href="http://d.android.com/tools/testing">Testing documentation</a>

*/

@RunWith(AndroidJUnit4.class)

public class ExampleInstrumentedTest {

@Test

public void useAppContext() throws Exception {

// Context of the app under test.

Context appContext = InstrumentationRegistry.getTargetContext();

assertEquals("com.example.user.enyatravelbataan",

appContext.getPackageName());

}

}

这是我的build:gradle(app)

apply plugin: 'com.android.application'

android {

compileSdkVersion 24

buildToolsVersion "24.0.3"

useLibrary 'org.apache.http.legacy'

repositories {

mavenCentral()

}

defaultConfig {

applicationId "com.example.user.enyatravelbataan"

minSdkVersion 16

targetSdkVersion 24

versionCode 1

versionName "1.0"

testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

multiDexEnabled true

}

buildTypes {

release {

minifyEnabled false

proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

}

}

}

dependencies {

compile fileTree(include: ['*.jar'], dir: 'libs')

compile(name: 'wikitudesdk', ext: 'aar')

// compile 'org.apache.httpcomponents:httpclient:4.5'

// compile 'org.apache.httpcomponents:httpcore:4.4.1'

compile files('libs/MD5Simply.jar')

compile files('libs/GenAsync.1.2.jar')

compile 'com.facebook.android:facebook-android-sdk:[4,5)'

compile 'com.android.support:appcompat-v7:24.2.1'

compile 'com.android.support:multidex:1.0.0'

compile 'com.google.android.gms:play-services:9.8.0'

compile 'com.google.android.gms:play-services-location:9.8.0'

compile 'com.google.android.gms:play-services-appindexing:9.8.0'

compile 'com.android.support:cardview-v7:24.2.1'

compile 'com.squareup.picasso:picasso:2.5.2'

compile 'com.android.support:design:24.2.1'

compile 'com.android.volley:volley:1.0.0'

compile 'com.android.support:support-v4:24.2.1'

testCompile 'junit:junit:4.12'

}

repositories {

flatDir {

dirs 'libs'

}

}

apply plugin: 'com.google.gms.google-services'

回答:

尝试

androidTestImplementation 'com.android.support:support-annotations:23.1.0'

androidTestImplementation 'com.android.support.test:runner:0.4.1'

androidTestImplementation 'com.android.support.test:rules:0.4.1'

添加以下上面的依赖项部分

configurations.all {

resolutionStrategy.force 'com.android.support:support-annotations:23.1.0'

}
