我在Android Studio 3.2.1和Android Studio 3.4上嘗試過，如果我在gradle文件中啟用Java 8并運行espresso測試，則會收到以下錯誤消息：java.lang.RuntimeExceptionCause: java.lang.RuntimeException經過多次試驗，我發現從gradle文件中刪除Java8支持可解決此問題。但是Java 8對于我的項目很重要。您有更好的解決方案嗎？這是我的代碼：import static androidx.test.espresso.action.ViewActions.click;import static androidx.test.espresso.assertion.ViewAssertions.matches;import static androidx.test.espresso.matcher.ViewMatchers.withId;import static androidx.test.espresso.matcher.ViewMatchers.withText;import androidx.test.espresso.Espresso;import androidx.test.ext.junit.runners.AndroidJUnit4;import androidx.test.filters.LargeTest;import androidx.test.rule.ActivityTestRule;import com.dubizzle.workshopsample.R;import org.junit.Rule;import org.junit.Test;import org.junit.runner.RunWith;@RunWith(AndroidJUnit4.class)@LargeTestpublic class MainActivityUiTest {  @Rule  public ActivityTestRule<MainActivity> mActivityRule      = new ActivityTestRule<>(MainActivity.class);  @Test  public void testShareButtonClickedUi() {    Espresso.onView(withId(R.id.txtStatus))        .check(matches(withText("Hello World!")));    Espresso.onView(withId(R.id.btnShare)).perform(click());    Espresso.onView(withId(R.id.txtStatus))        .check(matches(withText("onShareButtonClicked")));  }}
