问题描述

我正尝试在测试一个新的项目的Andr​​oid这个缓存库。结果
当我运行该项目，我得到这个logcat的：

I´m trying test this cache Library in a new project Android.
When I run the project, I get this Logcat:

我克雷格·安德鲁斯并复制从项目的Htt presponseCache两个罐子< A HREF =htt​​ps://github.com/JakeWharton/DiskLruCache相对=nofollow> DiskLruCache由Jake沃顿在我的libs文件夹：结果

I copied both jars from projects HttpResponseCache by Craig Andrews and DiskLruCache by Jake Wharton in my libs folder:

这是我的MainActivity.java：

This is my MainActivity.java:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    final long httpCacheSize = 10 * 1024 * 1024; // 10 MiB
    final File httpCacheDir = new File(getCacheDir(), "http");

    try {
        com.integralblue.httpresponsecache.HttpResponseCache.install(httpCacheDir, httpCacheSize);
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }        
}

我在其他线程读取汇入作业的顺序的问题，所以在订单＆放大器;在Java构建路径导出选项卡，我把这个放在第一位：
结果

I read in other threads that it´s problem of the order, so in the Order & Export tab in the Java Build Path, I put this in first place:

我打扫proyect，重建并没有什么工作，问题仍然存在...结果
任何想法...？？

I clean the proyect, rebuild and nothing work, the problem persist...
Any idea...??

感谢。

推荐答案

由于您使用的 disklrucache-2.0.2.jar 和 HTT presponsecache-1.3.jar

在库 HTT presponsecache-1.3.jar 使用 disklrucache-1.2.1.jar

在 disklrucache-1.2.1.jar 的包是： com.jakewharton 但是在2.0.2版本的包被更改为 com.jakewharton。 disklrucache

In disklrucache-1.2.1.jar the package is: com.jakewharton but in version 2.0.2 the package is changed to com.jakewharton.disklrucache

这是根本原因。

如果你想使用 disklrucache 你应该使用1.2.1版

If you wanna use disklrucache you should use version 1.2.1

您可以从这里下载//www.mediafire。 COM /下载/ e2q4vz7kdlwxxr3 / disklrucache-1.2.1.jar （的.jar）

You can download from here: http://www.mediafire.com/download/e2q4vz7kdlwxxr3/disklrucache-1.2.1.jar (.jar)
