Hi all, I'm new to Android development, and I was wondering if anyone knew either how to make Tabs slide, or how to get a similar effect without tabs. I have quite a few tabs in my application, and it does not look good on devices with smaller screens. Or maybe tabs are not what I am looking for. If you don't know what I'm talking about...

Yeah, I checked my code for possible bottlenecks – not the issue. The last resort I tried before writing this post – commenting out all the touch processing code and looking at FPS then. Results ...
