Apps Problem with "intent"

[qw1]

Hello. I have some problem with a programming simple widget. I have 2
buttons (b0, b1) and 1 TextView (tv1). I want that: text in tv1
changes to value, witch is given in "intent.putExtra", on buttons
press. In other words, after b0 pressed, text is "b0", after b1
pressed - b1. But always I have "b1" in tv1. I have no idea, how it
can be.

My code:

public class WidgetProvider extends AppWidgetProvider {
     public static String ACTION_WIDGET_CONFIGURE = "ConfigureWidget";
     public static String ACTION_WIDGET_RECEIVER =
 "ActionReceiverWidget";
     @Override
     public void onReceive(Context context, Intent intent) {
         super.onReceive(context, intent);
     }
     @Override
     public void onUpdate(Context context, AppWidgetManager
 appWidgetManager,
             int[] appWidgetIds) {
         RemoteViews views = new RemoteViews(context. getPackageName(),
R.layout.main);

        Intent tent = new Intent(context, MainBR.class);
        tent.setAction(ACTION_WIDGET_RECEIVER);
        tent.putExtra("button", "b1");
        PendingIntent ptent = PendingIntent.getBroadcast(context, 0,
tent, 0);
        views.setOnClickPendingIntent(R.id.b1, ptent);

        Intent tent2 = new Intent(context, MainBR.class);
        tent2.setAction(ACTION_WIDGET_RECEIVER);
        tent2.putExtra("button", "b0");
        PendingIntent ptent2 = PendingIntent.getBroadcast(context, 0,
tent2, 0);
        views.setOnClickPendingIntent(R.id.b0, ptent2);

       appWidgetManager.updateAppWidget(appWidgetIds[0], views);
    }
}

RECEIVER:

public class MainBR extends BroadcastReceiver {
    /**
     * @see
android.content.BroadcastReceiver#onReceive(Context,Intent)
     */
    @Override
    public void onReceive(Context context, Intent intent) {
        AppWidgetManager appWidgetManager =
AppWidgetManager.getInstance(context);
        RemoteViews remoteViews = new
RemoteViews(context.getPackageName(), R.layout.main);
        ComponentName thisWidget = new ComponentName(context,
WidgetProvider.class);
        final String msg = intent.getStringExtra("button");
        remoteViews.setTextViewText(R.id.tv1, msg);
        appWidgetManager.updateAppWidget(thisWidget, remoteViews);
    }
}

P.S. I'm sorry for my not good English, it isn't my native language,
and I ask You to write simple, if it is possible. Thank you!
