Error code from Throwable - Android

问题

How can I get the error code from the Throwable

public void onFailure(Throwable exception) {

   }

I saw that we can get the error messages, LocalizedMessage etc

回答1:

Only HttpException gives you http error code. Make sure you check instance of before using it.

Here is the code:

if (throwable instanceof HttpException) {
        HttpException exception = (HttpException) throwable;
        switch (exception.code()) {
            case 400:
                // Handle code 400
                break;
            case 500:
                // Handle code 500
                break;
            default:
                break;
        }
    }

If you meant error code like 500 , 404 etc , you can use the following code snippet.

if (ex.getCause() != null) // ex is the Exception
            return ex.getCause().getMessage();

回答3:

public void onFailure(Throwable exception) {
   Log.i("onFailure","Throwable ",exception);
} 

you try this

Similar to nhp answer but i didn't get the ( exception.code() ) option using HttpException class so i used HttpResponseException class instead.

  if (throwable instanceof HttpResponseException) {
            HttpResponseException exception = (HttpResponseException) throwable;
            return exception.getStatusCode());
    }
