android - RxAndroid Room Flowable noClassDefError

Question

我需要处理Flowable<List<Object>>由ObjectDao.

道

@Dao
public interface DefectosDao
{
@Insert(onConflict = OnConflictStrategy.IGNORE)
void insertarDefectos(DefectoEntity defectos);

@Query("select * from defectos where cod_defecto = :cod")
Maybe<DefectoEntity> getByCod(String cod);

@Query("select * from defectos where pt = 1")
Maybe<List<DefectoEntity>> getPt();

@Query("select * from defectos where ct = 1")
Maybe<List<DefectoEntity>> getCt();

@Query("select * from defectos where apoyo = 1")
Flowable<List<DefectoEntity>> getApoyo();
}

处理程序

DataBase.getAppDatabase(Splash_Screen.this).Defecto().getApoyo()
                    .subscribeOn(Schedulers.newThread())
                    .observeOn(Schedulers.io())
                    .subscribe(item2->{
                        System.out.println(item2);});

错误

我已经尝试过Maybe对象和Single对象并且是正确的。

进口

implementation 'io.reactivex.rxjava2:rxjava:2.1.14'
implementation 'io.reactivex.rxjava2:rxandroid:2.0.2'
implementation 'android.arch.persistence.room:runtime:1.1.0'
implementation 'android.arch.persistence.room:rxjava2:1.0.0-alpha5'
implementation 'android.arch.lifecycle:extensions:1.1.1'
annotationProcessor 'android.arch.persistence.room:compiler:1.1.0'

我已经尝试使用RxJava版本1.0.1和2.0.1 - 同样的问题。
