I've just downloaded this library. I have added an ImageView to a panel for use as a splash screen. The animation works but not as designed. The only way I can get it to work properly is via a button click as in the demo programs. When called from the Activity_Create the horizontal animation e.g flips from the left hand edge instead of the middle of the image.
I had the same exact problem when testing with the example program. The solution - set up a timer with a small delay (i.e 200 ms) in your Activity_Create subroutine and in the Timer_Tick Subroutine invoke the animation effect and immediately stop the timer. I don't have time to post my sample project at the moment but if you can not get your project working please let me know and I 'll put it up here.
Start your animation in Activity_Resume, not in Activity_Create. That's also true for other libs needing that the display messages can be processed (that won't happen before Activity_Resume).
