ich habe einActivity in der ich eine private klasse habe daten. In demonSaveInstanceState Methode, versuche ich, dies eine Instanz von zu speichernData. Das ist meine ganze Tätigkeit:

<code>public class TestActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    }

    @Override
    public void onSaveInstanceState(Bundle outState){
        outState.putSerializable("TEST", new Data());
    }

    private class Data implements Serializable {

        private static final long serialVersionUID = -4312723541994925110L;

    }
}
</code>

Wenn ich jetzt die Ausrichtung des Geräts ändere, wird dieData Objekt wird gespeichert und wie es sollte gelesen. Wenn ich jedoch die Home-Taste drücke, stürzt die App im Logcat wie folgt ab:

Wenn ich die Zeile im KommentaronSaveInstanceState Methode so dasData Objekt istnicht gespeichert, verschwindet die App korrekt.

Hilfe dabei?
