Android Room RxJava无法交付异常

Question

我正在尝试修复crashlytics在我发布给play store的应用程序中报告的一些错误

我查看了日志，但我不知道如何修复它。。。

实际上，我所有的rx代码都是这样处理错误的：

class MyIntentService(
        private val disposable: CompositeDisposable = CompositeDisposable()
) : IntentService("MyIntentService") {

    ...

    override fun onHandleIntent(intent: Intent?) {
        disposable.add(
            workDao.getWorkById(getToday())
                .subscribeOn(Schedulers.io())
                .subscribe({
                    // my logic
                }, { t ->
                    Log.e(TAG, "error: ${t.message}", t)
                })
        )
    }

    override fun onDestroy() {
        super.onDestroy()
        disposable.clear()
    }
}

而WorkDao是：

@Dao
interface WorkDao {
    @Query("SELECT * FROM work WHERE id = :id")
    fun getWorkById(id: Long): Single<Work>
}

但是我在崩溃报告中找不到我的错误日志。

我该怎么办？

好的，在我看来，onDestroy在workDao.getWorkById（getDaily（））完成之前被调用。因此，当您的订阅者已经被释放时，它会抛出错误。您现在可以尝试通过以下链接处理来自RxJava本身的错误https://stackoverflow.com/a/49387916/2164363
