It is safer to use <code>Robolectric.getShadowApplication()</code> instead of using <code>Robolectric.application</code> directly.

Agree with answers of @EugenMartynov and @rds .... 

A quick example can be found at Volley-Marshmallow-Release

in NetworkImageViewTest.java

<code>// mNIV = new NetworkImageView(Robolectric.application);
 mNIV = new NetworkImageView(RuntimeEnvironment.application);
</code>

Volley link is available
<a href="https://android.googlesource.com/platform/frameworks/volley/+/marshmallow-release" rel="nofollow">https://android.googlesource.com/platform/frameworks/volley/+/marshmallow-release</a>

you have to add dependencies in volley module in android studio as :

<code>dependencies {
 testCompile 'junit:junit:4.12'
 testCompile 'org.mockito:mockito-core:1.10.19'
 testCompile 'org.robolectric:robolectric:3.1.2'

Ok, so I know many others said this answer before and might already outdated 

<pre><code> when(mockApplication.getApplicationContext()).thenReturn(RuntimeEnvironment.application);
 when(mockApplication.getFilesDir()).thenReturn(RuntimeEnvironment.application.getFilesDir());

 sharedPref = RuntimeEnvironment.application.getSharedPreferences(KEY_MY_PREF, Context.MODE_PRIVATE);
 sut = new BundleManagerImpl(mockApplication,
 processHtmlBundle, resultListener, sharedPref);
</code></pre>

I got null, because the when() part was AFTER the sut initialization. It might help some of you. 

also I have the 

<pre><code>@RunWith(CustomRobolectricTestRunner.class)
@Config(constants = BuildConfig.class)
</code></pre>

at the beginning of the class

Also

<pre><code> when(mockApplication.getApplicationContext()).thenReturn(RuntimeEnvironment.application.getApplicationContext()); works
</code></pre>

In some cases, you may need your app's context instead of the Robolectris default context.
For example, if you want to get your package name. By default Robolectric will return you <code>org.robolectric.default</code> package name. To get your real package name do the following:

build.gradle

<code>testImplementation 'org.robolectric:robolectric:4.2.1'</code>

Your test class:

<pre><code>@RunWith(RobolectricTestRunner.class)
@Config( manifest="AndroidManifest.xml")
public class FooTest {

@Test
public void fooTestWithPackageName(){
 Context context = ApplicationProvider.getApplicationContext();
 System.out.println("My Real Package Name: " + context.getPackageName());
}

}
</code></pre>

Make sure that in your Run/Debug Configurations Working directory is set to: $MODULE_DIR$

Actually, I need to get a response of an API call, for that I required <code>Context</code>.

How can we access context of an application in Robolectric?

实际上，我需要获得一个API调用的响应，为此我需要Context。
