Does your app use any PNG image resources? Looks like it does and looks like some PNG image is big enough to cause an OutOfMemoryError when a Bitmap instance is being created from the image. My development experience says that it depends on OS version, device model and current device RAM state. So don't be surprised it works on one device and doesn't on another. To prevent the OutOfMemoryError just make sure your Bitmap dimentions is not greater than doubled display dimentions. For instance, if your display is 320x240, then don't use Bitmaps larger than 640x480.
