我创建了一个使用了.NET集成的Android应用程序，omegle java客户端是一个开源项目形式的github，它有一个控制台客户端示例，在java控制台中工作正常，我试图在Android活动中插入代码，我希望在TextView中显示它并在需要时插入我自己的文本。
这是我的代码
MainActivity.java
package com.example.com.omegle.test;
import org.nikki.omegle.Omegle;
import org.nikki.omegle.core.OmegleException;
import org.nikki.omegle.core.OmegleMode;
import org.nikki.omegle.core.OmegleSession;
import org.nikki.omegle.event.OmegleEventAdaptor;
import android.os.AsyncTask;
import android.os.Bundle;
import android.widget.TextView;
import android.app.Activity;
public class MainActivity extends Activity {
TextView txt;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
OmegleChat om=new OmegleChat();
om.execute();
}
private class OmegleChat extends AsyncTask<Void, Void, Void> {
@Override
protected void onPreExecute() {
txt=(TextView)findViewById(R.id.omegle);
txt.append("Omegele Connection Started... \n");
}
@Override
protected void onProgressUpdate(Void... values) {
}
@Override
protected Void doInBackground(Void... arg0) {
// TODO Auto-generated method stub
OmgeleChatOn();
return null;
}
@Override
protected void onPostExecute(Void result) {
}
}
public void OmgeleChatOn()
{
Omegle omegle = new Omegle();
try {
System.out.println("Opening session...");
OmegleSession session = omegle.openSession(OmegleMode.NORMAL, new OmegleEventAdaptor() {
@Override
public void chatWaiting(OmegleSession session) {
System.out.println("Waiting for chat...");
}
@Override
public void chatConnected(OmegleSession session) {
System.out
.println("You are now talking to a random stranger!");
}
@Override
public void chatMessage(OmegleSession session, String message) {
System.out.println("Stranger: " + message);
}
@Override
public void messageSent(OmegleSession session, String string) {
System.out.println("You: " + string);
}
@Override
public void strangerDisconnected(OmegleSession session) {
System.out.println("Stranger disconnected, goodbye!");
//System.exit(0);
}
@Override
public void omegleError(OmegleSession session, String string) {
System.out.println("ERROR! " + string);
System.exit(1);
}
});
} catch (OmegleException e) {
e.printStackTrace();
}
}
}
现在这是错误日志，应用程序在几秒钟后崩溃，陌生人可以回复，并且在他的回复之后应用程序崩溃了这样 - ＆gt;
