我正在尝试在新项目Android中测试此缓存库 当我运行项目时,我得到了这个Logcat:

我从我的libs文件夹中的项目HttpResponseCache by Craig Andrews和DiskLruCache by Jake Wharton中复制了两个罐子:
这是我的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();
}
}
我在其他主题中读到了订单的问题,所以在订单&amp;在Java Build Path中导出选项卡,我把它放在第一位:
我清理了这个项目,重建并没有任何工作,问题仍然存在...... 任何的想法...??
感谢。
答案 0 :(得分:3)
因为您使用了 disklrucache-2.0.2.jar 和 httpresponsecache-1.3.jar
在库 httpresponsecache-1.3.jar 中使用 disklrucache-1.2.1.jar
在 disklrucache-1.2.1.jar 中,软件包为: com.jakewharton ,但在版本2.0.2中,软件包更改为 com.jakewharton。 disklrucache 强>
这是根本原因。
如果您想使用 disklrucache ,则应使用版本1.2.1
您可以从这里下载:http://www.mediafire.com/download/e2q4vz7kdlwxxr3/disklrucache-1.2.1.jar(。jar)
或源文件:https://www.mediafire.com/?933nqqe9j4227cc(。jar)
希望这可以帮到你。
