[ANDROID] In app billing v3 probleme

Bonjour à tous.

J'essaie aujourd'hui de mettre en place le système in app billing V3 et j'ai pas mal de soucis.
A l'heure actuelle, celui qui pose le plus de problème est un message d'erreur :

"Unable to start service Intent {act=com.android.vending.billing.InAppBillingService.BIND} : not found"

Petite précision : l'application a été faite en Windev Mobile et le package en Java.

Je n'ai jamais programmé d'appli android en Java (et n'en avait pas besoin pour l'instant, WinDev me satisfaisait pour mes petites applis persos.)

J'ai beau tourné le problème dans tout les sens, je m'y prends sans doute mal.

Voici le code de ma classe :

<code type="java">
package com.pack.packbilling;

import com.android.vending.billing.IInAppBillingService;
import android.app.Activity;
import android.content.ComponentName;
import android.content.Context;
import android.content.Intent;
import android.content.ServiceConnection;
import android.os.Bundle;
import android.os.IBinder;
import android.util.Log;


public class Pack_Payment extends Activity {

static final String SKU_Var1 = "1";
static final String SKU_Var2 = "2";
static final String SKU_Var3 = "3";
static final String SKU_Var4 = "4";

// The helper object
IabHelper mHelper;

IInAppBillingService mService;

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

ServiceConnection mServiceConn = new ServiceConnection() {
@Override
public void onServiceDisconnected(ComponentName name) {
mService = null;
}

@Override
public void onServiceConnected(ComponentName name,
IBinder service) {
mService = IInAppBillingService.Stub.asInterface(service);
}
};

bindService(new Intent("com.android.vending.billing.InAppBillingService.BIND"), mServiceConn, Context.BIND_AUTO_CREATE);

alert("4");
String base64EncodedPublicKey = "clé de mon appli";
alert("5");

// Compute your public key and store it in base64EncodedPublicKey
mHelper = new IabHelper(this, base64EncodedPublicKey);
mHelper.enableDebugLogging(true);
alert("6");

mHelper.startSetup(new IabHelper.OnIabSetupFinishedListener() {
public void onIabSetupFinished(IabResult result) {
if (!result.isSuccess()) {
// Oh noes, there was a problem.
alert("7");
return;
}
// Hooray, IAB is fully set up!
alert("8");
}
});
alert("8 bis");
}

// We're being destroyed. It's important to dispose of the helper here!
@Override
public void onDestroy() {
// very important:
if (mHelper != null) mHelper.dispose();
mHelper = null;
alert("9");
}

public void Start_Payment(String _IDProduit){
alert("10");
mHelper.launchPurchaseFlow(this, _IDProduit, 10001, mPurchaseFinishedListener);
alert("11");
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
alert("Y - onActivityResult(" + requestCode + "," + resultCode + "," + data);

// Pass on the activity result to the helper for handling
if (!mHelper.handleActivityResult(requestCode, resultCode, data)) {
// not handled, so handle it ourselves (here's where you'd
// perform any handling of activity results not related to in-app
// billing...
super.onActivityResult(requestCode, resultCode, data);
}
else {
alert("Z - onActivityResult handled by IABUtil.");
}
}

// Callback for when a purchase is finished
IabHelper.OnIabPurchaseFinishedListener mPurchaseFinishedListener = new IabHelper.OnIabPurchaseFinishedListener() {
public void onIabPurchaseFinished(IabResult result, Purchase purchase) {
alert("12");
if (result.isFailure()) {
// Oh noes!
alert("13");
return;
}
alert("14");
// Purchase successful
if (purchase.getSku().equals(SKU_Var1)) {
// bought 1/4 tank of gas. So consume it.
mHelper.consumeAsync(purchase, mConsumeFinishedListener);
}
else if (purchase.getSku().equals(SKU_Var2)) {
mHelper.consumeAsync(purchase, mConsumeFinishedListener);
}
else if (purchase.getSku().equals(SKU_Var3)) {
mHelper.consumeAsync(purchase, mConsumeFinishedListener);
}
else if (purchase.getSku().equals(SKU_Var4)) {
mHelper.consumeAsync(purchase, mConsumeFinishedListener);
}
}
};

// Called when consumption is complete
IabHelper.OnConsumeFinishedListener mConsumeFinishedListener = new IabHelper.OnConsumeFinishedListener() {
public void onConsumeFinished(Purchase purchase, IabResult result) {
alert("15");
if (result.isSuccess()) {
alert("16");
}
else {
alert("17");
}
}
};

static void alert(String _Message) {
Log.e("MonApp - ",_Message);
}
}

Par ailleurs, est-il possible que cela ne fonctionne pas sur le simulateur android ?
Merci beaucoup et bonne soirée
