[Mark Sharpley]

Just thought I would let everyone know  about this press release.


http://press.rim.com/release.jsp?id=4935


Think of the new user base *drools*

I would not be surprised if in the long term we start to see Blackberrys
running skinned android...

Re: [android-developers] Force close after adding resources and textview

[Mark Sharpley]

Hey everyone, thanks for taking the time time to reply. It really is
appreciated!

Implementing my initialization in onCreate() worked, fantastic stuff.

Thanks again

Mark

 Don't implement a constructor and do stuff in it.  Implement your

 position int from the images to get the right string from my array. However,
 this addition causes my app to force close when I try to run it.

 I have a feeling that I have totally butchered my working java code and
 you may very well cringe at what you are about to see. Apologies. I am

 If anyone could help me out, I would be most grateful. I have attached my

[android-developers] Force close after adding resources and textview

I was playing around with the galleryview and image switcher, and I decided
to implement a textview that describes my images as I scroll through them. I
created a string array, and added a text view in my layout xml. I then added
the string and textview to my code. I thought I could reuse the position int
from the images to get the right string from my array. However, this
addition causes my app to force close when I try to run it.

[android-developers] Preparing an app for the small screen.

[Mark Sharpley]

Hello Android Developers:

I have developed a simple app which I am now testing on various phones. One
of these is a HTC wildfire. On this phone I get the error cannot parse the
package. I have support for small screens and low densities in the manifest,
and I can't work out what else I need to do to resolve this. The app has
been built for 2.1, min sdk 4.
Will I need to borrow my friends wildfire to generate a log output?

Regards

Mark
