我正在尝试在一个新的Android项目中测试这个缓存库。
当我运行这个项目时，我得到了这个Logcat:

我从 Craig Andrews的HttpResponseCache 和 Jake Wharton的DiskLruCache 两个项目中复制了两个jar包到我的libs文件夹中：
这是我的MainActivity.java代码：
@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();
}
}
我在其他帖子中读到问题是顺序的问题，因此在Java Build Path的Order＆Export选项卡中，我将其放在第一位：
我清理了项目，重新编译了代码，但问题仍然存在...
有什么想法吗？
谢谢。
