[android-developers] android design pattern

[ytbryan]

hi all,

I'm new to android.

As i am building multiple activities, i realise that i have to code
out repetitively this segment.

Intent i = new Intent();
i.setClass(this, Main_Form.class);
startActivity(i);

So that i can return to the home page.

Is there some structural pattern or design pattern that i am missing
out? Like a Activities Manager that manage all the activities? can
someone give me some advice?

thanks.

[android-developers] Re: Bug in minSdkVersion or what?

[Indicator Veritatis]

Well, you got one thing right: you do not understand. You have been
too close to Android for too long, you simply do not understand how
the documentation is read by people who are not so close (or even by
those as close who are more careful readers). That is why you
underestimate how bad this one spot in the documentation is. For the
section I quoted, when read alone, really does read as if the issue of
those values is settled by those few lines. This is, after all, all on
the topic at that 'node' in the Javadoc, the node on .

So it is a surprise to the reader to find out that no, it is not
settled: the values are set by minSDKversion as well (in the default
case). By no means is the latter section "clearly there to expand upon
that material" as you say, since it is so far away, being a separate
and apparently unrelated node. Nor is this the only spot in the
documentation with such unexpected expansion in an even more
unexpected place. Why, the former is under  and the
latter is under . These are effectively two different
documents, since each gets its own distinct node in Javadoc. Nor is
there even a cross-reference suggesting to the reader of the one that
he needs to see the other for the 'expansion'.

Now I will admit there are bigger problems in the documentation. But I
haven't seen those get fixed in between 1.5 and 2.2 either. It seems
everyone at Google is as cavalier about it as you are. This does not
bode well for the future of Android.

[android-developers] Rendering intial screen issue

[Rajesh Pelluru]

Hi,
  I have three screens in my sample application i.e. MainScreen,
Screen1, and Screen2.

If I click on Button in Main Screen then Screen1 appears in my device.

If I click on Button in Screen1 then Screen2 appears in my device.

Now if I click on home button and again if I tap on my app it displays
Screen2.

Actual requirement of mine is it should display every time MainScreen if we
tap on my app in device.

Could anyone help me on the same.

[android-developers] Re: Capturing RAW data in Android 2.2(HTC Desire)

[blindfold]

Yes, many have reported problems with camera preview in portrait mode,
and one way out is to force your app in landscape mode and just not
use portrait. Otherwise, consider the solutions suggested in
http://code.google.com/p/android/issues/detail?id=1193 (I have not
tested those because landscape suited me best).

[android-developers] What is INSTRUMENTATION_CODE refers to

[manohar]

Hello Guys,

I have been working with Instrumentation test for couple of days, i
will get the output as follows
INSTRUMENTATION_STATUS_CODE: 1
 * INSTRUMENTATION_STATUS: class=com.foo.FooTest
 * INSTRUMENTATION_STATUS: test=testFoo
 * INSTRUMENTATION_STATUS: numtests=2
 * INSTRUMENTATION_STATUS_CODE: -2

I understood what does STATUS CODe stands for start(1)/pass(0)/
fail(-2)/error(-1)

At the end of my all the tests, after it displays time, it returns

INSTRUMENTATION_CODE: -1,  what does exactly it means?  Where i can
get more information?

if somebody roots a phone, even though they lose guarantee by doing so, 
there must be a reason for it, which indicates that the user might not

Its just a research study we are carrying. Certain operations can be

We would like to quantify certain statements we make.
Also, now that rooting is legal, I expect a rise in the no. of users

[android-developers] Re: how to dynamically remove widgets from a layout inside a layout ( nested ).

[metal mikey]

You'll need to use removeAllViews in combination with addView:

http://developer.android.com/reference/android/widget/RemoteViews.html

These methods were introduced in API Level 7 (i.e. Android 2.1).

The addView method in RemoteViews handles layout inflation so you
can't inflate them yourself.

Don't think you can ever have an EditText in an AppWidget though...you
could instead do what the Google Search Widget does and have a fake
EditText view that launches an Activity onClick.

[android-developers] Re: Statistics on Rooted Phones

[Tez]

Its just a research study we are carrying. Certain operations can be
performed on a rooted phone and some of them are security threats.
We would like to quantify certain statements we make.
Also, now that rooting is legal, I expect a rise in the no. of users
who would root their phones.

Cheers,
Earlence

[android-developers] Re: cannot get my location to work on android 2.2

[Mathias Lin]

It's a known issue with the emulator, see the bug report here:
http://code.google.com/p/android/issues/detail?id=8816
Works fine on real device. On emulator, use an older version (7 should
work).

[android-developers] Re: problem with GL_CLAMP_TO_EDGE

[Robert Green]

Bill,

Only devices that have the non-power-of-two extension (NPOT) can do
that.  Different chips support different extensions.  Most everyone
uses power of two anamorphically to do NPOT rendering.  Just pick the
closest power of two size (for a full screen draw, 512x256 for 1st gen
or 1024x512 for high density), squeeze your image into it and draw it
at the original aspect ratio and while you'll lose a little quality,
it will work.

[android-developers] how to dynamically remove widgets from a layout inside a layout ( nested ).

[mani]

Hi All,

 I have LinearLayout. Inside to that i have added one more Linearyout
( checkbox & text ).

(LinearLayout) one textView, (LinearLayout) Checkbox,textview , one
textview

Now whenever clicks the checkbox, i need to dynamically display
EditBox after the checkbox.

main.xml
---

 http://schemas.android.com/apk/res/
android" android:orientation="horizontal"
android:id="@+id/MainLayout"
android:layout_width="match_parent"
android:layout_height="match_parent">














test.xml:
-


http://schemas.android.com/apk/res/android";
  android:layout_width="wrap_content"
  android:layout_height="wrap_content">





On the click of checkbox listener i added a code like below.
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main1);
final CheckBox location =
(CheckBox)findViewById(R.id.checkbox);

location.setOnClickListener(new Button.OnClickListener(){

  public void onClick(View v) {

if(location.isChecked() == true)
{
 LinearLayout l = (LinearLayout)
findViewById(R.id.locationLayout);
 LayoutInflater linflater = (LayoutInflater)
getSystemService(Context.LAYOUT_INFLATER_SERVICE);
 View myView = linflater.inflate(R.layout.main,
null);
l.addView(myView);
   }
else
{
 LinearLayout l = (LinearLayout)
findViewById(R.id.locationLayout);
 LayoutInflater linflater = (LayoutInflater)
getSystemService(Context.LAYOUT_INFLATER_SERVICE);

 View myView = linflater.inflate(R.layout.main,
null);

l.removeView(myView);  // I want to the layout
which was added earlier. How do i do that.? I know this is not correct
solution.

}
}
});

Can anyone help me here.?

Thanks,

So the KeyEvent Listener is only for physical keyboards?
I see many devices that have only soft keyboards. This leads me to
think "What is the value of the Key Listener API then"?

[android-developers] Re: cannot get my location to work on android 2.2

[Kumar Bibek]

I think it's related to the configuration of your emulator. Have you
checked if the Google Maps app works on the emulator/phone? That might
give you a clue.

[android-developers] Re: Capturing RAW data in Android 2.2(HTC Desire)

[uday]

Thanks Blindfold for ur information... Currently im working on Camera
Capture in Android. I can able to display the image in portrait by
forcing the preview as portrait in AndroidManifest.xml file.. But the
image preview is not correct as i expected.. The image preview is like
streched... I dont have an idea of how to maintain the Aspect ratio so
that the image preview will be clear..

Do u have any idea on this?? I saw some of the blogs on this but no
luck..

Re: [android-developers] Re: Bug in minSdkVersion or what?

[Dianne Hackborn]

CALL_PHONE won't effect the visibility on any of those devices.

Using CAMERA without specifying that auto-focus is optional will, I believe,
hide it from the Tattoo (which I think doesn't have an auto-focus camera...
 though of course I may be wrong).

And of course not supporting small screens will hide it from the Tattoo.

Also you can use "aapt dump badging " to see the exact info
Market uses to classify your app.

[android-developers] problem with GL_CLAMP_TO_EDGE

[billconan]

hello guys,

I cannot guarantee my texture size be a power of two,   therefore, i'm
using GL_CLAMP_TO_EDGE,

but when i call glTexImage2D, or glutil.teximage2d, i always get the
Opengl Error Code 1281 Invalid Value.

this same setting seems to work on iphone.

does this mean that android only supports power of two texture maps?

if i hard code the bitmap size to be power of two, then my program
will work. otherwise the texture map is black.


see, this is how i set the texture map, it is exactly the same as the
official sample.

thanks

[android-developers] Re: Bug in minSdkVersion or what?

[Gustavo]

Thank you for the quick reply Mark.

I also tried to look for some apps that require the CALL_PHONE and
you're right, they're up and running but why is it not working with my
apps? firstly I thought it had something to do with my manifest,
source code or something... but when I built a very simple hello world
app with just the CALL_PHONE on the manifest file, it also didn't work
so I got really confused about what's going on.

I'm running out of ideas on how to make this work... maybe I'll try
building and publishing it from another computer or something. =S

I've published a simple app that contains all of uses permissions that
is required in my app. would you (or anyone who's reading this) mind
telling me if you can see it from your android? the app name is "my
test".
If any of you guys have any idea on how to make this work I would be
really grateful with your support.

Thanks again.

- Gus

[android-developers] cannot get my location to work on android 2.2

[sunny]

Hi Folks,
my app which was working on 2.1 and earlier version fails to run properly in
2.2. It relies on the location but I do not get any error message.

However under DDMS /logCat, I see a message saying:Error message while
getting the location address: Reason: this service is not available.

This is coming more as an information message rather than an exception or
error. The process that is printing it out is System.out.

Note that I did everything possible ( I can think of) to upgrade the app to
run in android 2.2

The API version was changed to 8.

The manifest file contains  all the following:-
...
...















anything else I need to do ?

its very frustrating... any help would be greatly appreciated..

thanks

Sunny

Your suggestion led me to discover the problem, which was that my

would be mounted by my development computer. I changed the "Connect to

[android-developers] Re: Activity inside a view

[Explore Android]

Thanks for all your feedback or suggestions.

Before posting this message I was already implementing the solution
that proposed by TreKing.
But I felt this is not a smart way of doing it. It would have been
nicer to have all my ActivityA behavior and GUI (with out any
modifications)
showed inside a frame layout of ActivityB.

I know TabHost does this but could not understand it's implementation
fully. So is the reason for posting this issue.

Does anyone has a simple example of to use LocalActivityManager or
something else to meet my requirements.

Thanks

Possibly. I can certainly see apps that require CALL_PHONE on the
Market with a Nexus One running 2.2:

-- Advanced Call Manager
-- recordAcall
-- QuickCall
-- Big Call
-- etc.

(note: I am not recommending any of these, I am merely pointing out
that they are visible to me on the Market and use CALL_PHONE)

[android-developers] Re: Bug in minSdkVersion or what?

[Gustavo]

Hi, it's me again.

So I think I've found a very serious problem here... This has nothing
to do with supports screens or sdk versions. I have built an app just
for testing this kind of behaviour and I realized that the problem is
on uses permission (weird!).

My tests:

I published a very simple hello world app and decided just to change
the manifest file.

This was tested not just 4 times but I would say like up to 30 times
to make sure, in every way possible... spent the whole day testing
this since the CALL_PHONE permission is the most important feature in
my app. I even tried with a different developer account, different
projects, package name and most of the times had to wait for like 15 -
20 minutes after publishing the app to make sure it's really not
showing on the other devices.

Devices I've tested:

HTC Tattoo - Firmware version: 1.6 - Model HTC Tattoo A3232
Motorola Milestone (AKA Droid) - Firmware version: 2.0.1 - Model A853
HTC G1 - Firmware version: 2.01 - Model T-Mobile G1

1st attempt (VISIBLE ON ANDROID MARKET FOR ALL OF MY 3 ANDROID
DEVICES):










2nd attempt (VISIBLE ON ANDROID MARKET ONLY FOR HTC TATTOO):










3rd attempt (VISIBLE ON ANDROID MARKET ONLY FOR HTC TATTOO):






4th attempt with a new project (VISIBLE ON ANDROID MARKET ONLY FOR HTC
TATTOO):






In conclusion, I realized that there's got to be something wrong with
the CALL_PHONE permission. does anyone have an idea why is this
happening? is that only with me? how to deal with it? any workaround?

Many thanks,

- Gus

Simplest is in onResume() to check if there has been a change and update

[android-developers] Picking two pictures at once

[Pedro Teixeira]

Hi, this snippet of code allows me to pick a picture and choose from a
list of options to send them..
I'm wondering if it'spossible to pick 2 pictures instead of just one?
Is it possible? thnk you

Uri U = Uri.fromFile(F);
Intent i = new Intent(Intent.ACTION_SEND);
i.setType("image/jpg");
i.putExtra(Intent.EXTRA_STREAM, U);
startActivity(Intent.createChooser(i,"Send Picture
using:"));

Wow, thanks for the quick responses. That simple for question 1, huh?
Call finish()? :)  Will do, ta.  (I just presumed that once you called
StartActivity, that was it, bam, you were out of the calling activity
and into the called).

What about part 2?  I want a visual refresh of Activity A when
returning to it from Activity B (or C, or even G), that reflects how
the game data that affects Acitivty A has changed since the user left

I would expect that FLAG_ACTIVITY_NO_HISTORY, android:noHistory, and
the finish() technique that I and Mr. Weiss mentioned would have
similar performance characteristics. The difference between them
appears to be:

-- FLAG_ACTIVITY_NO_HISTORY is good when the *caller* (the one
invoking startActivity()) is one making the decision about whether the
activity should be in the stack

-- android:noHistory is good when the activity is *never* in the stack

-- finish() is good when the activity is conditionally removed from
the stack (and, it's a bit better-known)

I keep forgetting about android:noHistory, and that might be a good
choice in this case:

It doesn't matter.  If your activity knows it doesn't want to be returned
to, I suggest it calling finish() on itself rather than relying on the
caller to set the correct flag.

Re: [android-developers] Activities I Don't Want the User to be able to go Back to

[Filip Havlicek]

About the second question, I suppose you store your game data somehow
(perhaps in a database?). So what would you do before drawing the slots is
select data from database and make an if statement. If (data for slot1 is in
the select from database) {show the data as label and add Activity 3 class
to the on-slot-click intent} else {show an empty slot and add Activity 2
class to the on-slot-click intent}. The same for other slots.

Best regards,
Filip Havlicek

[android-developers] Implementing a self-contained library project test project

[Paul Butcher]

In "Testing a library project" the Android documentation says:

> There are two recommended ways of setting up testing on code and resources in 
> a library project:
> 
> - You can set up a test project that instruments an application project that 
> depends on the library project. You can then add tests to the project for

How to achieve the first of these is pretty obvious, but the second (to me, at 
least) rather less so. After some experimentation, I've managed to get it 
working, but I'm not 100% happy with how I've done so. I would be very grateful 
for any suggestions for improvements.

I've described my solution here:

http://www.paulbutcher.com/2010/09/android-library-project-with-tests-step-by-step/

Many thanks in advance for any help you can offer.

Re: [android-developers] Activities I Don't Want the User to be able to go Back to

The simplest thing to do when activity A starts activity B but
activity A doesn't want to stay on the stack is for activity A to call
finish() right after it calls startActivity() with the intent to start
activity B.

Have Activity 2 call finish() after calling startActivity() for
Activity 3. When the user presses BACK in 3, 2 is gone, so they will
return to 1.

[android-developers] Activities I Don't Want the User to be able to go Back to

[JimBadger]

Hi,

I'm developing a non-realtime Android game, and am having trouble
figuring out the best way to sequence and control my activities.

For example, when the user first installs and runs the app, he's into
Activity 1: The Game.  He selects a new game slot (1 of 3) and goes to
Activity 2: Create Character, and from there Activity 3: World Map.

That scenario highlights two of my problems:

1) If the user presses the back button on Activity 3, I don't want him
going back to Activity 2, I'd want him back on the main menu; Activity
1.but

2) When the user does return to Activity 1, I want it to have auto-
updated to show his character name in one of the 3 game slots*

I just don't know how to control my activity stack, or activity
launching process in this manner.  Help me, please.

*From then on, when he clicks that game slot it goes straight to
Activity 3, but that was the easy part! :)

Thanks in advance for any assistance!

Regards,
James

Re: [android-developers] Re: Simple Key Event Questions

You can't get that from the IME.  What you get is edit operations via calls
on InputConnection.

You will need to implement your own keyboard in your app if you want to
monitor individual interactions with it.

Re: [android-developers] Re: How to detect device support multi touch without OnTouchListener's event?

You look at the package manager features as Dan said, and adjust your UI
appropriately.

At the time the c2dm stuff was being made available, the API had been
finalized and was on devices and they were just doing a slow roll-out to get
the server pieces in place.  It is a totally different situation than a
modification of the platform with new non-standard APIs and user
interactions that are still being developed.

Re: [android-developers] Re: Permission checked at install time, but what happens if the "permission user" is installed before the "permission definer"?

[Dianne Hackborn]

There isn't a way in the SDK.  You need to go through the permissions screen
so the user can approve the permissions being granted.  (adb install doesn't
go through permissions because the shell is running as the user.)

Re: [android-developers] How to compare the data in framebuffer

(Oh and even if it does let you read the framebuffer, it is probably going
to be *much* slower to read it than to re-render it.)

Hi, this is well outside the bounds of the SDK, so should be asked on
another group such as android-porting.  Also there is no guarantee that the
hardware will let you read the frame buffer.

You'd need industrial-strength Android devices for that, too (oil- dirt-

I suppose that should be taken care of by File.getName(). I might add
that a test case for this new code would be a good idea.

Didn't try that actually, thought getName() returns only "cachefile" (from

I didn't test it but in theory you don't even need ActivityGroup - you
can use it in any Activity since there is a ctor
LocalActivityManger(Activity parent)

[android-developers] Re: Split Path to get filename and extension

[Bob Kerns]

The Java File class does not provide an abstraction for "extension".
It's a bit too abstract and least-common-denominator for that.
Compared to when the File class was defined, modern filesystems are
more consistent about not actually enforcing it as a part of the
syntax, and about following it as a convention!

// Untested, yell at me if I got it wrong.
public static String fileExtension(File f) {
   String name = f.getName();
   int idx = name.lastIndexOf('.');
   return name.substring(0, idx);
}

public static string fileBaseName(File f) {
String name = f.getName();
int idx = name.lastIndexOf('.');
return name.substsring(idx + 1);
}

Where do you see in Android a spot for a user to set a device name to

[android-developers] Apps2Sd install/update failures on Froyo linked to smdl2tmp1.asec file

[Craig D]

I finally fixed a problem I was having with install/update of Apps
installed on my SD card on my NexusOne with Froyo installed reported
as Android issue 9593 (http://code.google.com/p/android/issues/detail?
id=9593). It turns out that there is a file called smdl2tmp1.asec in
the SD card app2sd directory (/mnt/secure/asec) that was causing the
problem (see the bug report for details).

My question is: What is this file (smdl2tmp1.asec) used for and why
doesn't the system erase it when finished with it?

[android-developers] Re: Developing Android app for tablet

[ben]

I would make sure your app isn't drawing anything to exact pixel
locations and sizes. If you're using the built in layouts you should
be in good shape. Also you can use the AVD manager to create an
emulator with larger resolutions and screen sizes. That should at
least give you some idea of what it will look like.

Run adb install -r, or publish an update to your app on the Market. I

Call it what you want, is there a way to make it happen?  I believe
the "in place update" would be sufficient to get the permission
recognized.

Use adb logcat, DDMS, or the DDMS perspective in Eclipse to examine
LogCat and take a look at the stack trace associated with your
"crash". That will tell you where things are going wrong.

adb install -r doesn't "re-install" an app. It does an in-place
update. This does have the effect of keeping your data around, but so
does a regular Market update.

[android-developers] gridview in custom dialog not working....crashes

[mani]

Hi all,

I have tried adding a grid view to a custom dialog. When displaying
the dialog it crashes.
But when tried displaying the grid view in normal activity it was
working.( without dialog )

I took the examples from developer android website.Took grid view and
tried to integrate in custom dialog.

I used two xml main.xml & category.xml.
Here is my code:

package com.android.test;


import android.app.Activity;
import android.app.AlertDialog;
import android.app.Dialog;
import android.content.Context;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.view.View.OnClickListener;
import android.widget.AdapterView;
import android.widget.BaseAdapter;
import android.widget.Button;
import android.widget.GridView;
import android.widget.ImageView;
import android.widget.TextView;
import android.widget.Toast;
import android.widget.AdapterView.OnItemClickListener;

public class test extends Activity {
/** Called when the activity is first created. */

public final static int CATEGORY_ID=0;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button button = (Button)findViewById(R.id.categories);

button.setOnClickListener(new Button.OnClickListener(){
public void onClick(View v) {
showDialog(CATEGORY_ID);
}
});
}
protected Dialog onCreateDialog(int id) {
Dialog dialog;
switch(id) {
case CATEGORY_ID:

AlertDialog.Builder builder;
AlertDialog alertDialog;

Context mContext = this;
LayoutInflater inflater = (LayoutInflater)
mContext.getSystemService(LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.categorydialog,
   (ViewGroup)
findViewById(R.id.layout_root));

TextView text = (TextView) layout.findViewById(R.id.text);
text.setText("Hello, this is a custom dialog!");
ImageView image = (ImageView)
layout.findViewById(R.id.image);
image.setImageResource(R.drawable.find);

GridView gridview = (GridView) findViewById(R.id.gridview);
   gridview.setAdapter(new ImageAdapter(this));

gridview.setOnItemClickListener(new OnItemClickListener()
{
public void onItemClick(AdapterView parent, View v,
int position, long id) {
Toast.makeText(test.this, "" + position,
Toast.LENGTH_SHORT).show();
}
});

builder = new AlertDialog.Builder(mContext);
builder.setView(layout);
dialog = builder.create();

break;
default:
dialog = null;
}
return dialog;
}

public class ImageAdapter extends BaseAdapter {
private Context mContext;

public ImageAdapter(Context c) {
mContext = c;
}

public int getCount() {
return mThumbIds.length;
}

public Object getItem(int position) {
return null;
}

public long getItemId(int position) {
return 0;
}

// create a new ImageView for each item referenced by the
Adapter
public View getView(int position, View convertView, ViewGroup
parent) {
ImageView imageView;
if (convertView == null) {  // if it's not recycled,
initialize some attributes
imageView = new ImageView(mContext);
imageView.setLayoutParams(new
GridView.LayoutParams(85, 85));
 
imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
imageView.setPadding(8, 8, 8, 8);
} else {
imageView = (ImageView) convertView;
}

imageView.setImageResource(mThumbIds[position]);

Re: [android-developers] Re: Crash on gesture recognize

[Filip Havlicek]

Hi Mor,

if it works with 99%, it's going to be hard. Right now I would try to
determine conditions under which the error is thrown.

For example, are you using the application on the same version of Android OS
as you created the gesture file? I'm pretty sure it shouldn't be a problem,
but who knows. Try to recreate the gestures file (on multiple versions of OS
if possible).

Aren't you using some deprecated methods? They might be fine when developing
application on, let's say 1.6, but might be an issue when you deploy the
application to 2.2.

It might be a bug in the gestures framework, although I wouldn't go that far
yet.

Best regards,
Filip Havlicek

[android-developers] Re: Google TV applications

[ben]

Dianne,

I understand that the market can't be opened up to everyone all at
once. I can only begin to imagine what a nightmare that would be to
manage. I just don't understand why this can't be more open like the
c2dm start was. C2DM can't have everyone on the market using it at
once. But at least it was open for everyone to apply to get into the
beta.

[ben]

Actually we do have the resources, and we do compete with them
directly. I would say were highly competitive with them. And anyone
who is a big player in the mobile market knows that being first to
market is a huge huge advantage. Look at the current android market, a
majority of the top apps on the market are the apps that were their
first, or things everyone is going to use such Maps.

 If they take users away from us then I don't see how our company
benefits from that at all.

[android-developers] Re: Permission checked at install time, but what happens if the "permission user" is installed before the "permission definer"?

[Flying Coder]

Mark & Dianne,
Thanks for the replies.  I was hoping there might some equivalent
of "adb install -r" that would allow my app to be re-installed without
losing its data (is it possible?).  Unfortunately, the backup/restore
to SD card won't work for this app because the SharedPreferences
contains some sensitive data.  It looks like I will have to go with
the plug-in approach.

Cheers,
Steve
