java无法解析user的方法_java – 无法解析符号AndroidJUnit4

我正在尝试为我的应用添加loginfacebook.但是当我添加一个需要这样做的存储库时.它导致了一个错误.

AndroidJUnit4现在无法解决.

ExampleInstrumentedTest.java

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 Testing documentation

*/

@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());

}

}

这是我的构建：gradle(app)

buildToolsVersion "24.0.3"

useLibrary 'org.apache.http.legacy'
