Android Room：使用 Room.inMemoryDatabaseBuilder 更新的 Dao 方法的“NoSuchMethodError：无接口方法”

Question

我在 Android 上使用 Room。因此，我的数据模型类具有正确的 Room 注释和一个公共构造函数。它使用构建器模式并尝试保持不变。我是here.

然后我的@Dao-annotated 接口与@Query、@Update 和@Insert 注释紧挨着所有方法声明。就在here.

最后，我得到了我的 Dao 测试类，它使用了Room.inMemoryDatabaseBuilder。是here。

因此，当我在GoalsDaoTest 中运行测试时，除了两个之外，它们都通过了：一个使用注释为@Update 的Dao 方法，另一个其Dao 方法在其@Query 中使用SQL UPDATE 命令。

这是我的测试设置和拆卸，使用Room.inMemoryDatabaseBuilder：

@Before
public void initDb() {     
    mDatabase = Room.inMemoryDatabaseBuilder(InstrumentationRegistry.getContext(),
            SelfCareDatabase.class).build();
}

@After
public void closeDb() {
    mDatabase.close();
}

这是第一个失败的测试：

@Test
public void updateArchivedAndGetById() {
    // When inserting a goal
    mDatabase.goalDao().insertGoal(GOAL);

    // When the goal is updated
    mDatabase.goalDao().updateArchived(GOAL.getId(), true);

    // When getting the goal by id from the database
    Goal loaded = mDatabase.goalDao().getGoalById(ID);

    // The loaded data contains the expected values
    assertGoal(loaded, GOAL.getId(), GOAL.getTitle(), GOAL.getInterval(), GOAL.getPolarity(), true, GOAL.getTouched());
}

这是我运行它时产生的错误：

java.lang.NoSuchMethodError: No interface method updateArchived(Ljava/lang/String;Z)V in class Lcom/beatboxchad/android/selfcaredashboard/data/source/local/GoalsDao; or its super classes (declaration of 'com.beatboxchad.android.selfcaredashboard.data.source.local.GoalsDao' appears in /data/app/com.beatboxchad.android.selfcaredashboard-1/base.apk)

然而，该方法已在GoalsDao 类中正确声明和注释：

/**
 * Update the Archived status of a goal
 *
 * @param goalId    id of the goal
 * @param archived status to be updated
 */
@Query("UPDATE goals SET archived = :archived WHERE entryid = :goalId")
void updateArchived(String goalId, boolean archived);

这是另一个测试：

@Test
public void updateGoalAndGetById() {
    // When inserting a goal
    mDatabase.goalDao().insertGoal(GOAL);

    // When the goal is updated
    Goal updatedGoal = new Goal.Builder(ID)
            .setTitle(TITLE2)
            .setPolarity(POLARITY2)
            .setInterval(INTERVAL2)
            .setArchived(ARCHIVED2)
            .setTouched(TOUCHED2)
            .build();

    mDatabase.goalDao().updateGoal(updatedGoal);

    // When getting the goal by id from the database
    Goal loaded = mDatabase.goalDao().getGoalById(ID);

    // The loaded data contains the expected values
    assertGoal(loaded, ID, TITLE2, INTERVAL2, POLARITY2, ARCHIVED2, TOUCHED2);
}

这是它的错误：

然而！迷惑我！是什么疯狂导致计算机撒谎？目标道.java 摘录：

/**
 * Update a goal.
 *
 * @param goal goal to be updated
 * @return the number of goals updated. This should always be 1.
 */
@Update
int updateGoal(Goal goal);

我已经用尽了这一项上所有容易实现的目标。一切似乎都符合文档（尽管我怀疑我的不可变 builder'd Goal 类），并且我尝试遵循以下地方给出的建议：

Why Room entities don't work with immutable properties in Android

Espresso Test Failing: No interface method trackUsage() in UsageTracker.java

Room Persistence Library run time exception when calling Rooms inMemoryBuilder method

但我没有使用 Kotlin，也没有使用 @Relation 注释，即使我在 build.gradle 文件中使用了各种不同的版本，它仍然坏掉了。好的一面是，我学到了很多关于那个无聊的部分。 tl;博士我很难过。

以防万一它是有用的上下文，我的应用程序强烈基于来自https://github.com/googlesamples/android-architecture 的 todo‑mvvm‑databinding 示例。我提到这一点是因为示例中的所有内容都有效，但是我增加了一些复杂性，并且可能在此过程中犯了一个更有经验的人会认识到的错误。特别是，我修改了 @Entity 目标类（示例应用程序中的任务），试图保持它不可变并添加构建器模式和几个属性。我也没有完成对它的修改——touched 即将成为它自己的表。

我也不擅长将接口和一堆注释转换为代码的故障排除。任何关于在哪里解决这个问题的建议都与它会导致的答案一样有用。我是 Android Studio、Java 和整个构建过程的新手。

谢谢！
