Answer 1

As my knowledge you can not open a dialog from Service. But you have one option to open popup window from service for that

1) Make a Layout of popup window.

2) Create on activity and set layout as content view in this activity

3) In manifest you have to write this

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

4) From service you have to call this activity when you want to open popup.But keep it mind that from service you have to set flag of intent as

intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 

now you can able to open your activity as popup window.

EDIT

1) Layout main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
<EditText  android:id="@+id/web"
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    />
<EditText 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    />
    <EditText 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    />
</LinearLayout>

2) test2.java which will act as Popup

package com.example.AutocompleteTextView;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;

public class Test2 extends Activity{

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

3) Manifest.xml file

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.AutocompleteTextView" android:versionCode="1"
    android:versionName="1.0">
    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".CustomAutoComplete" android:label="@string/app_name">
        </activity>

        <activity android:name="test1">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity android:name="Test2" android:theme="@android:style/Theme.Dialog">
        </activity>
        <service android:name="MyService"></service>
    </application>
</manifest> 

4) Service MyService.java

package com.example.AutocompleteTextView;

import android.app.Activity;
import android.app.AlertDialog;
import android.app.Service;
import android.content.Context;
import android.content.DialogInterface;
import android.content.Intent;
import android.os.IBinder;

public class MyService extends Service{

    @Override
    public void onCreate() {
        super.onCreate();
    }

    @Override
    public void onStart(Intent intent, int startId) {
        super.onStart(intent, startId);
        Intent intent1 = new Intent(this, Test2.class);
        intent1.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        startActivity(intent1);


    }
    @Override
    public IBinder onBind(Intent intent) {
        // TODO Auto-generated method stub
        return null;
    }

}

this is the activity from which i am starting a service

package com.example.AutocompleteTextView;

import java.lang.reflect.InvocationTargetException;
import java.lang.reflect.Method;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.webkit.WebView;
import android.widget.FrameLayout;

public class test1 extends Activity {


    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main); 
        startService(new Intent(getApplicationContext(), MyService.class));
        finish();

    }
}
