我正在尝试测试我的 Activity，但无法导入 ActivityTestRule。

    // Optional -- UI testing with UI Automator
    androidTestImplementation 'androidx.test.uiautomator:uiautomator:2.2.0'
    
}

编辑 我也尝试过 ActivityScenarioRule。同样的问题，无法解决符号 ActivityScenarioRule

public ActivityScenarioRule rule = new ActivityScenarioRule<>(LoginActivity.class);
