GWT2.1 M3: How to upgrade from gwt2.1 m2

All,


yesterday Chris Ramsdale posted a new article on http://googlewebtoolkit.blogspot.com/2010/08/gwt-21-milestone-3-is-now-available.html 

The link provided for this new build references to a zipfile. I yesterday tried
and I had to make some code changes (I have a project build with GWT2.1 m2).


Unfortunately, there was no more documentation provided, so after my code changes I ran into some problems. I posted my question on the Google Web Toolkit Groups and thankfully I got an answer. 


See this link for more information: http://groups.google.com/group/google-web-toolkit/browse_thread/thread/5573595ccbd63ef8#


The link provided in this post, can be used in eclipse to "Install new software".
I still have to give it a try, but I'll keep you posted.

Google CL: Just cool!

So I was not at home and I could remotely log in at my home-computer (mac mini) through SSH. I wanted some people to show some photos that were on my home-computer. Downloading them through SSH/SFTP was too cumbersome.


Luckily I remembered the announcement on Google Command Line Interface. 


Huh ?


Yes, Google on the commandline on your unix/Linux machine (requires that you have Python).


I could easily create a Picasa WebAlbum from the commandline and then through a browser see it (and hosting by Google is lightning fast).


Just a similar line like this and my problem was solved.

 google picasa create --title "Cat Photos" ~/photos/cats/*.jpg




Note that you'll need to provide a username when this line is executed. A browser will start and ask you to grant permission to this Google Service (OAuth stuff).


Anyway, when this was done, I could do whatever I want on the commandline.


I'm really looking forward to some new features of the GoogleCL.


The GoogleCL is a really cool tool....lots of interesting things to do....

Twanslate! Twitter On the Fly Translate

So the worldcup is going on for a while and in this internet age, twitter is the first place to search for information and reactions worldwide!


This is one of the coolest parts of twitter. Unfortunately, I don't get all the languages (since the "world" is reacting)


So that got me thinking: As a developer I know some cool technologies from Google and I like twitter.


The result is: Twanslate. which can we found at http://twiggered.appspot.com


What I used for creating such an app:

• Google Webtoolkit 2.1 m2  (at this moment the latest greatest. I was wondering how the data representation widgets were working. This was the perfect opportunity for that!)
• Google Ajax API, especially Google Language API
• Google Font API for the nice new modern fonts!
• Google AppEngine (nice for hosting...deployment was really easy! Thanks Google!)
• Last but not least, Twitter API.

The result is the application you see. Just search, the data is queried from twitter, processed in put in of the new data representation widgets of the Google WebToolkit! It works perfectly together.

I'm now pondering about some other cool features. If you have ideas, let me know. I might be able to put it in this solution.

This was just for showcasing the possibilities of the new GWT 2.1 and it looks promising!

BTW,  it works on my Nexus One :) 

Finally Froyo (FRF91) on my nexus One

So finally there seems to be the final version of Nexus one. I found the note on Engadget.com.


Now there was a bit of a problem. Since I already installed an early version of Froyo (FRF50) upgrading to  FRF91 was kind of a hassle. You have to perform an update on all the intermediate version before you can go to the latest Froyo.


Luckily the update was possible thanks to this link: http://forum.xda-developers.com/showthread.php?p=7032281


There are some attachments on the middle of the page. You'll need to download them and install them in the correct order (Your Nexus One will abort the installation).


To install the updates perform the following per update.

1. Download the Froyo Android 2.2 image and radio files (see xda link above)

2. Put the whole zip file in the root directory of your Nexus One’s SD card. Call it "update.zip"

3. Reboot the phone while holding down the trackball button.

4. Go to Fastboot then Recovery.

5. Install the new zip file.

6. Enjoy the new Froyo Android 2.2! Hurray!

If needed, I have the files also (if you don't want to register  @xda-developers). Just sent me an email.

Have fun, you'll notice that your phone lasts longer on the battery and is faster!

Froyo on Nexus One

Although Android 2.2 (aka Froyo) is not available for everyone over the air (OTA), one can still manually install the new Android on the Nexus one (assuming the Nexus One/N1) is running Android 2.1.

Check out this link

http://www.androidpolice.com/2010/05/22/breaking-nexus-one-users-download-your-froyo-here/

It's true, there are two links. The download of almost 45Mb is the one you'll need.

Just follow the instructions on this page and enjoy a snappier Nexus One.

So far no problems. I tried the tethering stuff, turning my Nexus One into a Wifi-Hotspot using the 3G connection. Works like a charm!

Give it a try.

GWT Data Representation Widget

So at GoogleIO we could see how Bruce showed some cool demos using the new GWT 2.1 features. The most interesting part for me was the GWT Data Representation Widgets, especially since we are using data aware components/widgets in QAFE.

I tried to find some information about the usage of the "Datagrid" that Bruce showed. Finally when I downloaded the Eclipse Plugin (with GWT 2.1 m1 SDK) I could not find a sample with the new DataGrid.

Through the Hierachy (F4) in Eclipse I found the Widget super class for all widgets and there I saw CellList. Apparently this is the class with which the demo was done.

Searching on this I found that several other developers were looking for the same information. Unfortunately there is no complete demo/ code samples.

Until I hit this : the SVN browser for GWT.

http://code.google.com/p/google-web-toolkit/source/browse/branches/2.1/bikeshed/?r=7995

This is the place to be!!! Here are some code samples, although not much comments, but with a little analysis and trying it yourself, this is a good place to start using the Data Represenation Widgets!

Happy developing!

Google TV is happening

Yesterday Google TV Companion Box was revealed by Logitech: Logitech Revue. Sony is also providing a product "Sony Internet TV" These developments are very promising.

If you didn't know what the effect would be of GoogleTV for you, check this video:

Be sure to follow these developments, it feels like exciting applications are coming up.

Did you know, Android applications will work on the GoogleTV ? Well, they will according to the announcements made @GoogleIO.

Keep you posted.
