hi,
I get nuts on this, who can help?
package de.test;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.ObjectOutputStream;
import java.io.Serializable;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.widget.TextView;
public class SerialisiereAndroidActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
try {
Serialisiere pi = new Serialisiere(3, Math.PI, "pi");
((TextView) findViewById(R.id.tv1)).setText("Serialisiere: " +
pi.toString());
pi.writeIt("pi.ser");
}
catch( Exception e) {
Log.d( "SerialisiereAndroidActivity", e.toString() );
}
}
public class Serialisiere implements Serializable {
private static final long serialVersionUID =
-3922493985071195239L;
private int i;
private double d;
private String s;
public Serialisiere(int i, double d, String s) {
this.i = i;
this.d = d;
this.s = s;
}
public void writeIt(String filename) throws IOException {
FileOutputStream fos = openFileOutput(filename,
MODE_WORLD_WRITEABLE);
ObjectOutputStream oos = new ObjectOutputStream(fos);
oos.writeObject(Serialisiere.this);
oos.close();
fos.close();
}
@Override
public String toString() {
return "i=" + i + " d=" + d + " s=" + s;
}
}
}
the problem is:
oos.writeObject(Serialisiere.this);
this throws an java.io.NotSerializableException.
who can help me on this?
greetings,
darolla
