title: Run unit test with robolectric get Resources$NotFoundException
body: <p>The offical demo can't run correctly. When I run the unit test demo, it show android.content.res.Resources$NotFoundException: String resource ID #0x7f050000 in the consle.</p>
  
  <p>As the reason of network , I can't use m2e to create my project. But I download all the needed .jar with maven on another computer and copy the to this one, then add them into Eclipse IDE Java Build Path --> Library</p>
  
  <p>And here is my source code:</p>
  
  <pre><code>public class MainActivity extends Activity {
    protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
      View button = findViewById(R.id.login);
      button.setOnClickListener(new View.OnClickListener() {
        public void onClick(View view) {
          startActivity(new Intent(MainActivity.this, LoginActivity.class));
        }
      });
    }
  }
  </code></pre>
  
  <p>and the test code are as follow:</p>
  
  <pre><code>@RunWith(MyRunner.class)
  public class MainActivityTest {
    @Test
    public void onCreateShouldInflateTheMenu() {
    Activity activity = Robolectric.setupActivity(MainActivity.class);
  
    final Menu menu = shadowOf(activity).getOptionsMenu();
    assertEquals("First menu item", menu.findItem(R.id.item1).getTitle());
    assertEquals("Second menu item", menu.findItem(R.id.item2).getTitle());
  }
  </code></pre>
  
  <p>When I run the testcase with junit test, they following error info are shows in the "failure trace":</p>

  <p>I also tried to override the RobolectricTestRunner and add the <em>@Config</em> tag, but it's the same result.
  How can I fix the problem and run the demo successfully?</p>
