我将kdu_jni.jar文件导入为外部jar。该库是本机编码的。当我使用JAVA项目时,它可以工作,但Android不接受这个'方法。
package com.jp2.pathology;
import java.io.File;
import java.io.IOException;
import java.net.URI;
import java.net.URISyntaxException;
import kdu_jni.Jp2_threadsafe_family_src;

import com.jp2.view.jpip.JPIPSocket;
import com.jp2.view.kakadu.JHV_KduException;
import com.jp2.view.kakadu.JHV_Kdu_cache;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.ImageView;
public class MainActivity extends Activity {
private ImageView mainImg;
private JPIPSocket socket;
private URI uri;
private JHV_Kdu_cache cache;
private static File cachePath;
private Jp2_threadsafe_family_src familySrc = new Jp2_threadsafe_family_src();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mainImg = (ImageView) findViewById(R.id.main_img);
try {
try {
connect();
} catch (JHV_KduException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
public void connect() throws IOException, JHV_KduException{
JPIPResponse res;
socket = new JPIPSocket();
try {
uri = new URI("jpip://192.168.1.71:3312");
res = (JPIPResponse) socket.connect(uri);
String jpipTargetID;
if (res.getHeader("JPIP-tid") == null)
throw new JHV_KduException("The target id was not sent by the server");
else
jpipTargetID = res.getHeader("JPIP-tid");
if (jpipTargetID.contains("/")) {
jpipTargetID = jpipTargetID.substring(jpipTargetID.lastIndexOf("/") + 1);
}
cache = new JHV_Kdu_cache(jpipTargetID, cachePath);
cache.addJPIPResponseData(res);
Log.d("CACHE", cache.toString());
} catch (URISyntaxException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
这是错误:

如何将原生jar库导入Android Project?
答案 0 :(得分:0)
问题是您包含的jar依赖于Android SDK中不可用的Java方法。
你应该明白,即使Android程序是用Java编写的,它们也不是由JVM运行的。
