I just use the screen record function on Android. 90% of my devices are rooted and flashed with custom ROMs (makes it easier to get logcat logs and other misc dev stuff) so it’s possible that this recording function I’m using isn’t exposed in normal Android builds. If you can flash a custom ROM on an Android device, I’d suggest it, as it makes lot of things from a developer standpoint exponentially easier.
As a sidenote: I know I’m biased, but I have a dev machine that I built for ~$300 running Win7 and everything within the sim is smooth. I just don’t record my computer screen because I already have a process for recording on device, and I haven’t had time to research other methods. If you’re seeing choppy performance from all code, including the Corona-supplied sample projects, the issue might not be the sim.
