当使用proguard进行模糊处理时，通过改装进行自定义错误处理会产生java.lang.reflect.UndeclaredThrowableException

已编写用于改装的自定义错误处理。当

minifyEnabled false

时，代码工作正常。当我启用proguard时，我得到以下异常

错误处理程序

public class RestErrorHandler implements ErrorHandler {

@Override
public Throwable handleError(RetrofitError cause) {
    Response r = cause.getResponse();

    if (r != null && r.getStatus() == 400) {

        try {
            RestError mRestError = (RestError) cause.getBodyAs(RestError.class);
            final String exception = mRestError.getMessages().get(0);
            return new UnauthorizedException(exception);
        } catch (Exception e) {
            e.printStackTrace();
            LogUtility.NoteLog(e);
        }
    }
    return cause;
}

我对使用proguard和改装相当陌生。我无法理解如何处理异常。

看起来像

未经授权的异常

是已检查的异常（扩展自

异常

，而不是

运行时异常

），这意味着您需要在所有服务接口上声明

抛出

子句

interface MyService {
  @GET("/")
  Something doSomething() throws UnauthorizedException;
}

---

Proguard默认情况下删除异常属性

---

-keepattributes Exceptions

将确保您的

可丢弃文件在混淆后仍保留在代码中。
我已经这样做了，杰克。当我混淆代码时，它停止工作。在没有proguard的情况下，它可以完美地工作。
