Espresso-UI-Tests nicht erkennen onView()

Habe ich verbrachte den ganzen Tag einrichten Junit4 instrumentation-tests mit dem Espresso, aber kann einfach nicht scheinen zu bekommen, dass der Letzte Schritt. Egal was ich mache es wird nicht erkannt das onView() Methode. Ich habe versucht mehrere SDK - /support-lib-Versionen und bisher nichts. Ich habe alles durchlebt das google-setup-guides und vielen stackoverflow-Beiträgen, drehen hier ist meine Letzte Hoffnung.

Meinem test (befindet sich in src/androidTest/java/lv/my/test)

package lv.my.test;

import android.support.test.rule.ActivityTestRule;
import android.support.test.runner.AndroidJUnit4;
import android.test.suitebuilder.annotation.LargeTest;
import lv.my.android.activities.LoginActivity;

import org.junit.Before;
import org.junit.Rule;
import org.junit.Test;
import org.junit.runner.RunWith;

@RunWith(AndroidJUnit4.class)
@LargeTest
public class LoginActivityTest {

    private String mStringToBetyped;

    @Rule
    public ActivityTestRule<LoginActivity> mActivityRule = new ActivityTestRule<>(LoginActivity.class);

    @Before
    public void initValidString() {

    }

    @Test
    public void changeText_sameActivity() {
//       onView not recognized here

    }
}

PS. Ich benutze roboguice, könnte dass das Problem sein?
