java.lang.NoSuchMethodError:没有接口方法onTransitionToIdle()V [英] java.lang.NoSuchMethodError: No interface method onTransitionToIdle()V

问题描述

请我是Android测试的新手，我正在尝试修复初始的NavigationView测试，但我遇到了错误.我只是想打开抽屉，然后单击菜单以转到新活动.

PLease i am new to Android Testing, i have being trying to fix an initial NavigationView Test bu i am getting the error. I was just trying to open the drawer and click a menu to go to a new activity.

java.lang.NoSuchMethodError: No interface method onTransitionToIdle()V in class Landroid/support/test/espresso/IdlingResource$ResourceCallback; or its super classes (declaration of 'android.support.test.espresso.IdlingResource$ResourceCallback' appears in /data/app/com.bellman.inecparrot.mock-2/base.apk)

以下是我正在进行的测试:

Below is the test that i am runnning:

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

    /**
     * {@link ActivityTestRule} is a JUint {@link Rule @Rule} to launch your activity under test
     * <p>
     * <p>
     * Rules are interceptios which are executed for each test method and are important building
     * block for JUnit tests.
     */

    @Rule
    public ActivityTestRule<HomeActivity> mActivityTestRule =
            new ActivityTestRule<>(HomeActivity.class);
    private IdlingResource mIdlingResource;



    @Test
    public void clickOnAndroidHomeIcon_OpensNavigation() {
        //check the left drawer is closed at startUp
        onView(withId(R.id.drawerlayout))
                .check(matches(isClosed(Gravity.LEFT))); //left Drawer should be closed
        //open Drawer
        onView(withContentDescription(TestUtils.getToolbarNavigationContentDescription(
                mActivityTestRule.getActivity(), R.id.toolbar
        )))
                .perform(click());

        //Check if drawer is open by now
        onView(withId(R.id.drawerlayout))
                .check(matches(isOpen(Gravity.LEFT)));

        //close the drawer
        onView(withContentDescription(TestUtils.getToolbarNavigationContentDescription(
                mActivityTestRule.getActivity(), R.id.toolbar
        ))).perform(click());
    }

    @Test
    public void clickGovNavigationItem_ShowsGovActivity() {
        //open drawer
        onView(withId(R.id.drawerlayout))
                .check(matches(isClosed(Gravity.LEFT))) //left drawer should be closed
                .perform(open());
        //start the gov Screen
        onView(withId(R.id.navigation_view))
                .perform(navigateTo(R.id.action_gov));

        //check that the Gov Activity was opened
        onView(withId(R.id.gov_frag_frame))
                .check(matches(isDisplayed()));
    }

}

推荐答案

听起来ProGuard正在删除所需的接口之一.我认为您需要在Proguard配置中添加以下内容:

It sounds like ProGuard is removing one of the interfaces that is needed. I think you need to add a line like the following to your Proguard config:

-保留公共接口android.support.test.espresso.IdlingResource $ ResourceCallback {*;}

-keep public interface android.support.test.espresso.IdlingResource$ResourceCallback {*;}

目前我还没有办法对其进行测试，因此，如果这还不太正确，并且您需要对其进行调整，那么这里有一个指向Proguard手册的保留"选项的链接: http://proguard.sourceforge.net/manual/usage.html#keepoverview

I don't have a way to test it at the moment, so if that's not quite right and you need to tweak it, here's a link to the Proguard manual for the "keep" options: http://proguard.sourceforge.net/manual/usage.html#keepoverview
