Error code from Throwable - Android

Question

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.

Answer 1

Only HttpException gives you the 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;
    }
}

Answer 2

This is the Kotlin version:

if(throwable is HttpException){
    when(throwable.code()){
        404->  // Manage 404 error
        else-> // Manage anything else
    }
}
