How can I build a dialog which is launched by a service?

I think my problem is easy to fix for you. I have a service running in the background and starting an Intent which starts an activity, which opens a dialog. Her is my code from the service:

Intent todialog = new Intent();
todialog.setClass(myService.this, openDialogInSleep.class);
todialog.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(todialog);

and here is the activity:

import android.app.Activity;
import android.app.AlertDialog;
import android.os.Bundle;

public class openDialogInSleep extends Activity{

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    new AlertDialog.Builder(openDialogInSleep.this)
    .setTitle("huhu")
    .setNeutralButton("close", null);
}   
}

Finally the android manifest:

<activity android:name=".openDialogInSleep" android:theme="@android:style/Theme.Dialog"></activity>

My Problem is, that there is not shown the dialog with the title "huhu" and the button "close". There is only shown a dialog in a strange form which simply shows a part of my activityname. What did I forget? Please help me.

One thing you have missed is to call show() on the dialog generated by the AlertBuilder.

UPDATE

If I understand you correctly you don't want the activity to take control of the screen but rather just show the dialog?

If that is the case I don't think it is possible, the only way you can create a similar effect is by using a Toast Message. This can be launched from your Service and you wouldn't require the activity at all.

You forget to chain in show() to actually show your dialog.

new AlertDialog.Builder(openDialogInSleep.this)
    .setTitle("huhu")
    .setNeutralButton("close", new OnClickListener() {

        @Override
        public void onClick(DialogInterface arg0, int arg1) {
            openDialogInSleep.this.finish();
        }

    })
    .show();
