org.apache.http.client.HttpClient与Android Plateform冲突

标签： conflict apache-httpclient-4.x androidhttpclient

Android 4.4.2旧版org.apache.http.client.HttpClient但我想使用我通过jar添加的新版org.apache.http.client.HttpClient。

如何强制Android从jar而不是框架本身使用org.apache.http.client.HttpClient。

我正在使用此

创建客户端 
this.mRequestQueue = Volley.newRequestQueue(
                    mCtx.getApplicationContext(), new HttpClientStack(HttpClientBuilder.create().build()));

并且因为它从框架（即旧版本）导入org.apache.http.client.HttpClient，所以它会引发异常

你不能。

您基本上有两种选择：

  1. 将HttpClient重新打包到不同的命名空间

    2. org.apache.http - ＆gt; thank.you.google.org.apache.http

    1. 使用官方HttpClient Android端口，该端口与Android完全API兼容，但仅与HC的库存版本部分兼容。有关详细信息，请参阅此resource
