我知道有很多关于 roboelectric 和 gradle 的帖子，但我无法为我的项目设置它。

让我们从情况开始。

我的项目有三种构建类型，每种构建类型使用不同的包名称。我正在使用一些需要在清单中使用包名称的 SDK，所以为了解决这个问题，我在清单中使用了一个键，然后在每个 buildType 中我使用它

manifestPlaceholders = [_MY_PACKAGENAME_: getName()]

因此，我按照 gradle 指南中的说明配置了 roboelectirc，但我无法使其工作。我尝试了不同的东西，例如插件 Android Unit Test 和所有的解决方案，我得到了不同的错误。

喜欢java.lang.NoSuchMethodError cannot be cast to java.lang.RuntimeException

任何人都可以帮助我吗？

测试示例代码：

@Config(emulateSdk = 18)
@RunWith(RobolectricTestRunner.class)
public class RoboElectricVerifyTest {

    @Test
    public void simpleTest() throws Exception {
        final Context context = Robolectric.getShadowApplication().getApplicationContext();
        System.out.println("Package name is: " + context.getPackageName());

        Activity activity = Robolectric.buildActivity(MainActivity.class).create().get();
        assertThat(activity != null);
    }

}

这是输出
