<p>I'd like to hard-code some test values -- let's say, a list of four objects whose "foo" attribute is set to some number.</p>
<p>Is there a more concise way than this?</p>

1,726,121 | 1,726,122 | Displaying animated GIFs in Android | <p>I am getting my GIF image as a byte array from the server. Now since android cannot display animated GIFs in the ImageView, I have to decode it and show it as a movie. </p>
<p>The problem that I am facing here is that the GIF that I am getting from the server has its dimensions set for an iPhone. So the GIF comes out really small on Android devices with larger screen/resolution. </p>
<p>To fix this I have two alternatives:
1) I could either extract each Bitmap from the GIF and scale them according to my screen size. But for that I will have to mess up the aspect ratio and the image will come out stretched. </p>
<p>2) Or I could ask the server guys to add support for Android devices, so that they could send me the GIF according to my screen size.</p>
<p>Please recommend as to what the best solution would be. Do tell if you have any suggestions of your own.</p>
