Android Design for ICS

Hello and happy new Year :o)
You want to make an Android application, for multiple devices, excellent ! But before take few minutes to read what are the design guide lines. Google just open a web site to explain those guidelines. The article is simple clear and complete. So just read it :
http://developer.android.com/design/index.html
This article is really good for all the GUI stuff, you should read it , even if you are on Froyo, just to have a clear vision on GUI guide line and ressources.

(Anyway, keep in mind 3.9% of the devices have an SDK version greater than 2.3. see Android target, so not all is your concern )
Okay, this is the today news :o)

So, Thanks who?
Thanks, Android2ee, the Android Programming Ebooks :o) Android Training :o)

Spinner, Managing size and text

Hello,

Sometimes, when using a spinner, you want to manage its size and the font of the displayed text.

To do that you need to do 3 actions (I do that change on the Android spinner example : http://developer.android.com/guide/tutorials/views/hello-spinner.html) 

1.      Create a spinnertext.xml in your layout folder and define how the spinner’s title has to be displayed

2.      Change your spinner size in your main.xml (where your spinner is defined)

3.      Change your spinner declaration in your activity

Define your pictures for all densities : ldpi,mdpi,hdpi (and xhdpi if you target tablet)

In my previous post we understood why we need to declare our images in the layout file in dp (density-independent pixels). Thus, whatever the density of the screen, the image is the "same" size.
The corollary is: if you define/declare your pictures (in the folder drawable) once regardless of the density, they'll appear coarse in hdpi (and also in ldpi).
