NotificationCompat.Builder doesn't work, Android 2.2.1

Question

I have next code:

NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(
        this).setSmallIcon(R.drawable.ic_launcher)
        .setContentTitle("My notification")
        .setContentText("Hello World!");

Why it doesn't work? It shows nothing. Testing on Android 2.2.1.

Update. Code of activity:

import android.app.Activity;
import android.app.AlertDialog;
import android.os.Bundle;
import android.support.v4.app.NotificationCompat;
import android.view.Menu;
import android.view.View;

public class LoginActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_login);
    }

    public void start(View view) {
        NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(
                this).setSmallIcon(R.drawable.ic_launcher)
                .setContentTitle("My notification")
                .setContentText("Hello World!");
    }
}

Button in layout:

<Button
    android:id="@+id/startButton"
    android:layout_width="100dp"
    android:layout_height="wrap_content"
    android:layout_above="@+id/aboutButton"
    android:layout_alignLeft="@+id/aboutButton"
    android:layout_marginBottom="20dp"
    android:onClick="start"
    android:text="Start" />

UPDATE2. Error log:

The exceptions says it requires a content intent and you're not providing one — Zharf, Feb 04 '13 at 10:33

It works:

Intent resultIntent = new Intent(this, LoginActivity.class);
PendingIntent resultPendingIntent =
    PendingIntent.getActivity(
    this,
    0,
    resultIntent,
    PendingIntent.FLAG_UPDATE_CURRENT
);

NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(
        getApplicationContext()).setSmallIcon(R.drawable.ic_launcher)
        .setContentTitle("My notification")
        .setContentText("Hello World!")
        .setContentIntent(resultPendingIntent);

NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
manager.notify(FM_NOTIFICATION_ID, mBuilder.build());

When writing code for versions that came before API 11 you should include the support library and instead of calling the Notification.Builder you need to call NotificationCompact instead.

Try reading in the Android support Library page and going over the sample projects for these things.

EDITED:

Try out below code:

NotificationCompat.Builder builder =
        new NotificationCompat.Builder(this)
        .setSmallIcon(R.drawable.ic_launcher)
        .setContentTitle("Notifications Example")
        .setContentText("This is a test notification");
// Add as notification
NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
manager.notify(FM_NOTIFICATION_ID, builder.build());

It compiles ok, and I use android.support.v4.app.NotificationCompat. When I launch app on phone It shows nothing when I call "start" function. – Maximus Feb 04 '13 at 08:07
