Question

我希望在我的Android应用程序中包含最新版本的Http，即4.2.1。现在希望从Apache网站下载该库，并将其包含在libs文件夹中，然后包含到我的应用程序的构建路径中。

在包含Http-4.2.1时，我在logcat中得到了以下输出

我的问题我可以这样做吗？这是否会与已包含的Http库版本以及SDK一起产生冲突？

Answer 1

不幸的是，这个问题没有优雅和干净的解决方案。您唯一的选择是使用maven shade插件或使用可用库的预先打包的分支将所有HttpClient类移动到自定义命名空间（'org.apache.http' - ＆gt;'my.http'）here

修改

截至今天，我们也可以使用官方port of Apache HttpClient 4.3 to Google Android。

Answer 2

<classpathentry kind="con" path="com.android.ide.eclipse.adt.ANDROID_FRAMEWORK">
<accessrules>
<accessrule kind="nonaccessible" pattern="org/apache/http/**"/>
</accessrules>
</classpathentry>

我修复它修改应用程序的.classpath文件我在开源项目open-gpstracker中找到了解决方案

包含Http-4.2.1和Android App
