[ANDROID] Portare applicazione Java su Android

[bircastri]

Salve ragazzi,

spero di non uscire fuori tema.

Vorrei iniziare a programmare in ANDROID.

Da un pò di documenti presi qua e la ho vsto che bisogna programmare in JAVA.

Bene ho realizzato una piccola applicazione nulla di che in JAVA che funziona.

Vorrei adesso convertirla per farla girare un un tablet con android versione 2.2.

Ho installato in eclipse il plugin di android.

Purtroppo anche quando esego il seguente codice.

import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;

public class HelloAndroid extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        TextView testo = new TextView(this);
        testo.setText("Ciao Mondo");
        setContentView(testo);
    }
}

Preso dal sito di andorid il compilatore mi va in errore.

Prima escono una serie di messaggi in rosso che sono talmente veloci che non risco a leggerli e poi mi compare questo

#
# A fatal error has been detected by the Java Runtime Environment:
#
# Internal Error (classFileParser.cpp:3375), pid=292, tid=708
# Error: ShouldNotReachHere()
#

# An error report file with more information is saved as:

#
# If you would like to submit a bug report, please visit:

#

cosa sbaglio???

Mi potete aiutare???

Grazie mille

Problemi di compatibilità? Ho avuto qualche brutta esperienza (con database sotto Windows 64bit e JDK/JRE a 64bit) con tecnologie apparentemente pensate per sistemi e JRE a 32 bit.
Qui trovi qualcosa a riguardo:

http://stackoverflow.com/questions/1...s-7-pro-64-bit

e questa è una checklist degli step iniziali da intraprendere con android/java sotto eclipse

[bircastri]

Ascolta io ho win 7 a 32 bit non ho a 64

[bircastri]

Allora ho risolto, inpratica dovevo configurare in RUN di eclipse.

Adesso si passa alla cosa più complicata,

come faccio a portre la mia applicazione java su android???
