java - 不是抽象的，不会覆盖 AsyncHttpResponseHandler 中的抽象方法 onFailure(int,Header[],byte[],Throwable)

Question

大家晚上好。我真的需要一些帮助。过去我在编译应用程序时遇到过一些问题，但目前的情况几乎足以让我不想辞掉我的日常工作。

我有一个在 eclipse 中运行良好的 Android 应用程序。但是，自从上周升级以来，我一直无法让它恢复运行。太糟糕了，我决定将应用程序导入 Android Studio。

现在我已经将应用程序导入到 Android studio 中，顺便说一下，我确实喜欢这样做，但我遇到了一个我似乎无法弄清楚的错误。

如果我在没有“android-async-http-1.4.5.jar”的情况下编译应用程序，我会收到以下错误信息:

Error:(29, 30) error: package com.loopj.android.http does not exist

对于应用程序中存在异步函数的每个区域都会被调用。但是，一旦我添加“android-sync-http-1.4.5.jar”，每次调用该函数时，整个应用程序都会出现以下错误:

Error:(74, 104) error: <anonymous com.peekatucorp.peekatu.ChatActivity$1> is not abstract and does not override abstract method onFailure(int,Header[],byte[],Throwable) in AsyncHttpResponseHandler
Error:(75, 13) error: method does not override or implement a method from a supertype

请帮忙。我不知道我错过了什么。

我需要帮助。我一直在尝试让这个应用程序再次运行 72 小时。有人请帮助我。提前谢谢你。我已经阅读了我可以在网上找到的所有资源，但现在我陷入了死胡同。

您只需在成功和失败方法 header 中将 org.apache.http.Header 替换为 cz.msebera.android.httpclient.Header
