Robolectric 3.0 Nullpointer on DefaultPackageManager.getActivityInfo()

问题

I try to create a Robolectric test (3.0-rc02) for the following Activity:

public class NotificationActivity extends ActionBarActivity {

private NotificationFragment fragment;

@Override
protected void onCreate(final Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_notification);
}
}

The test is looking like this:

@Config(manifest = IConfig.MANIFEST_PATH, emulateSdk = IConfig.SDK_VERSION, reportSdk = IConfig.SDK_VERSION)
@RunWith(RobolectricTestRunner.class)
public class AbstractFragmentTest {

    @Test
    public void test() {
        Robolectric.buildActivity(NotificationActivity.class).setup().visible();
    }

where SDK_VERSION = 18.

When running the test, I get this error:

java.lang.NullPointerException
    at org.robolectric.res.builder.DefaultPackageManager.getActivityInfo(DefaultPackageManager.java:164)

Anyone knows what I'm doing wrong over here?

Issue solved

Using FragmentActivity in stead of ActionBarActivity did the trick to me. My main logic is in a fragment (DialogFragment) inside the activity. Both activities are supporting the DialogFragment, so for my functional tests it doesn't matter which of the 2 parent activities I use.

回答1:

ActionBarActivity is deprecated. Use AppCompatActivity instead
