Android resource linking failed error: attribute 'android:name' in

Well, I wrote a testing code for checking to open new activity while a button click. My code is looks like

@Test
public void checkNewActivity() {

    onView(withId(R.id.button_open_new_activity)).perform(click());
    onView(withText("SecondActivity")).check(matches(isDisplayed()));

}

I also declared in both activity in the manifest.

<activity
        android:name=".SecondActivity"
        android:label="@string/title_activity_second"
        android:theme="@style/AppTheme.NoActionBar">

    </activity>
    <activity
        android:name=".MainActivity"
        android:label="@string/app_name"
        android:theme="@style/AppTheme.NoActionBar">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

But faced error in build the test file. Error

Android resource linking failed /Users/shihab/StudioProjects/AndroidTesting/app/build/intermediates/merged_manifests/debugAndroidTest/AndroidManifest.xml:9: error: attribute 'android:name' in tag must be a valid Java class name.
