You need to update to support different densities. You are probably creating a bitmap in compatibility mode that would thus be the size of an HVGA screen, so when you draw it to your window it needs to be scaled up for the higher density screen. Once you use android:targetSdkVersion="4", the compatibility code will be turned off, so you will be working in the true pixel density of the screen. Of course your app needs to be able to deal with this.
