您好,我正在尝试使用 APACHE COMMONS LIBRARY 为 android 制作应用程序。此应用程序必须连接到服务器并使用 Telnet 发出一些命令。这是我的应用程序...清单:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.test"
android:versionCode="1"
android:versionName="1.0" >
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-library android:name="org.apache.commons.net.telnet.TelnetClient" />
<uses-sdk
android:minSdkVersion="7"
android:targetSdkVersion="15" />
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name="com.example.test.MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
活动主要
package com.example.test;

public class MainActivity extends Activity {

@Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
bottone1 = (Button) findViewById(R.id.bottone1);
bottone1.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
//
new Connection().execute();
}
});
}
@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;
}
private class Connection extends AsyncTask {
@Override
protected Object doInBackground(Object... arg0) {
connessione();
return null;
}
}
private void connessione()
{
PrintStream output;
TelnetClient tc = new TelnetClient();
try
{
tc.connect("www.servertotelnet.it",23);
}
catch(Exception ex)
{
ex.getMessage();
}
output = new PrintStream(tc.getOutputStream());
try
{
Thread.sleep(500);
output.println("users");
output.flush();
Thread.sleep(500);
output.println("password");
output.flush();
Thread.sleep(500);
output.println("mkdir TEST");
output.flush();
Thread.sleep(500);
}
catch(Exception ex)
{
ex.getMessage();
}
try
{
tc.disconnect();
output.close();
}
catch(Exception ex)
{
ex.getMessage();
}
}
}
当我运行它时,Eclipse 不会返回任何错误。请帮助我:(我错在哪里?
