Room and RX Java
0
I have a method in which a data sheet is committed.
private void saveItemsToDB(List<NewsEntity> newsEntityList) {
Disposable disposable = Completable.fromCallable((Callable<Void>) () -> {
newsDatabase.getNewsDao().deleteAll();
Utils.log("******Delete All******");
for (NewsEntity newsEntity : newsEntityList) {
Utils.log("******Save " + newsEntity + "******");
newsDatabase.getNewsDao().insert(newsEntity);
}
return null;
})
.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.subscribe();
compositeDisposable.add(disposable);
}I need to save them to the database. I work with Room. There is a method
@Insert(onConflict = OnConflictStrategy.REPLACE)
void insertAll(NewsEntity... newsEntities);
@Insert(onConflict = OnConflictStrategy.REPLACE)
void insert(NewsEntity newsEntity);
No saving occurs Link

According to RxJava2 documentation, it's not allowed to pass null through rx chain. I suppose, it's the cause of the problem.
Completable.fromCallable((Callable<Void>) () -> {
...
return null; // don't do this
})
If you don't want to return anything, use Completable.fromAction()
