Projede eksik olan Avarası bulun

Question

Bir projede eksik bir onError() bulmaya çalışıyorum. Bu, bir abonelik throwables işlemez, çünkü bu alt yazıyı bulmak ve onError yöntemini eklemek istiyorum çünkü uygulama çöker demektir.

Maalesef StackTrace burada gerçekten yararlı değildir ve sadece throw new IOException çizgisini ama daha hiçbir şey gösterir:

onError() yok abonelik (kodda çizgi) bulmak için herhangi bir fikir?

Answer 1

Bu, hata ayıklaması için bir acı olabilir. Son derece yeterli Action1<Throwable> [facepalm] içinde bir hata vardı.

En iyisi, hata ayıklamaktı; bu, genel bir hata işleyicisini kaydetmektir.

RxJavaPlugins.getInstance().registerErrorHandler(new RxJavaErrorHandler() { 
     @Override 
     public void handleError(Throwable e) { 
      Log.w("Error",e); 
     } 
});  

github üzerinde bir tartışma: onError uygulanmazsa https://github.com/ReactiveX/RxJava/issues/2293

Answer 2

, ardından OnErrorNotImplementedException istisna RxJava Bu size kodunuzda gerçeği gördü. Görünüşe göre, RxJava onError yöntemini çağırmayı başaramadı ("Hataları Observer.onError'a iletmeye çalışırken hata oluştu")

Kök istisnasını bulmak için bir hata işleyicisi kaydetmeyi deneyebilirsiniz.

static { 
    RxJavaPlugins.getInstance().registerErrorHandler(new RxJavaErrorHandler() { 
     @Override 
     public void handleError(Throwable e) { 
      e.printStackTrace(); 
     } 
    }); 
}
