ilimitado Web Entwickler Blog

Yesterday, while doing a break at work, i had the idea to implement the awesome Nexus live wallpaper for our blog in JS. So i sat down yesterday evening and implemented the Nexus live wallpaper with CSS3 and a little bit of JQuery animation magic. Here is the result:

For now this should just work in webkit browsers!, because i used the -webkit-gradient + opacity properties. I only tested it in the google chrome browser. Support for firefox, a canvas version + the blurring effect will follow.

You need a chrome-dev-channel version in order to use these cli parameters…if not subscribe to the dev-channel first.

Linux (tested on ubuntu):

1. Open a shell
2. Launch chromium with following parameters –enable-webgl –no-sandbox (it should look like this: “chromium-browser –enable-plugins –enable-webgl –no-sandbox”

Windows:

1. Right click on your Chrome icon
2. Click on “properties”
3. Append arguments –enable-webgl –no-sandbox to your current path (it should look like this: “chrome.exe –enable-webgl –no-sandbox”

Here are my notes from todays Tech Crunch Munich Event…not very structure and directly pasted from my wave…have fun.

Today we run in some trouble, while trying to “run” our test suites against our android code. So here is a short howto run your tests in eclipse. As example we are going to use the APIDemo tests…

1. Import API Demos to eclipse:
New -> AndroidProject -> Create Project from existing source -> Location: <android-sdk>/platforms/android-1.5/samples/ApiDemos/

2. Test code in APIDemo project:
Take a look at the tests folder in APIDemos android project. The whole test code for APIDemos is located in there.

Twitter is down for more then 50 minutes now and users on Tech Crunch also claim that some Facebook services are down. Twitter just posted this on there status site:

“Site is down
We are determining the cause and will provide an update shortly.

Update: we are defending against a denial-of-service attack.”

Facebook works for me but it seems like a serious DOS-Attack at least on twitter. Let’s wait and see what will happen…

I had the problem to extract multiple .tar files (all in the same folder). Doing this by hand was kind of annoying and because i like the heuristic not to do same things more then three times, i wrote a little bash script. The script takes the archive type i.e. .tar, .tar.gz as first parameter and then automatically extracts all the archives files, in the given folder, to subdirectories (foldername of created subdirectory is the basename of the file). So here is the code..maybe it could save a little bit of your time.

Zunächst müssen die .jar Dateien von der Projektseite geladen und entpackt werden:
Download von http://code.google.com/p/smali/

• baksmali-0.93.jar  ist der Disassembler
• smali-0.92.jar ist der Reassembler

Nachdem die Dateien herunterladen wurden einfach in einen Ordner Eurer Wahl kopieren. Nun können wir auch schon mit dem Dis-/Reassemblieren beginnen.

Disassemblieren:

• Gewünschte .apk Datei in einen leeren Ordner kopieren
• Datei dort entpacken (in Ubuntu entweder per Doppelklick auf die .apk oder via Konsole:

mkdir <yourApp>
cd <yourApp>
adb pull /system/app/<yourApp>.apk ./
unzip <yourApp>.apk

Nachdem wir heute morgen voller Freude die Rundmail des Google Android Market Support gelesen haben, in der es heisst:

… We have also added seller support for developers from Germany, France,
Spain, the Netherlands, and Austria. Developers from these countries can
now go to the publisher website to publish their priced applications…

haben wir gerade als eine der ersten deutschen Firmen unsere Android App “My Name Is” für (unschlagbare) 0.99 € in den Android Market eingestellt.

Imagine you have just written your new ground breaking android application. It took you weeks developing it because you have to go to work and can just code after quitting time or at the weekends. You finally finished it up and the application works great and it’s roll out time baby.
But should you make it a free or paid app? If you make it a paid app users won’t have the opportunity to review your application before buying it. As a consequence less people will download it (we where analysing this by browsing through the market, listing the download counts of all paid apps…), and advertising also doesn’t make much sense, because the application mainly runs as background service and uses the notification system to interact with the user. But all you know is, that your little application could be very useful to a lot off people and therefore there is no doubt to make it a free app.

Die offizielle Seite des Android Market von Google ist (im Moment noch) wenig funktional und unübersichtlich. Man kann zum Beispiel nicht auf eigene Apps linken und man kann den Market nicht im Webbrowser durchsuchen.
Die einzige Möglichkeit besteht also zur Zeit darin die Market Apps auf dem Android Telefon zu durchsuchen.
