I am using AnnotEditBox to add text in the pdf.( I am using this sdk in both platforms of iOS and Android)
In order to represent immediately entered chars at AnnotEditBox while typing the keys over keyboard, I make a call to <SetEditTex>t when each keyboard input event is fired and also make a call to <SetRect> to change the annotation's width according to the length of new string.
The issues are following:
1. We are getting lagging experience while typing the text. (both iOS and Android)
2. If we are typing the text too quickly, we are getting the crash, the crash is occurred from sdk. (currently we are crashed in Android)
1. If you are re-rendering after every keyboard input, it will sure lead to this effect.
(performance wise, you should do that after the user finishes editing)
2. for the crash issue, can you please send us your code to be able to replicate it?
