Textinput: past/copy problems

[nesergen]

The problems appear on the real device. I have 'ASUS memopad HD7' .

1. I typed the text in a text field. Further I try to insert a new letter into the text middle, but together with this letter the text which costs to the right of the cursor is inserted also. After clear the text field and type a letter inserting previouse part of text. Problem leaves after switch-off virtual keyboard.

2. I copy the text from one field, I insert it into another, but I receive unreadable symbols. I code all text in my program by Unicode.

1. I don't think it's kivy's fault, because I've had similar issue sometimes and it was caused by the android keyboard(or the way it works). Only happened to me when I was using Gingerbread(2.3.x), or when newer versions were too laggy.
2. same with me, unfortunately

@akshayaurora A good one for you :)

[picibucor]

same on win10, python3.5.1

@picibucor, have you compiled kivy yourself with msvc?

[dessant]

@picibucor, I'm copying text from one field to the next in kivycatalog win10, and there are no issues. Could you share a runnable example which reproduces your issue? Kivy version?

@KeyWeeUsr, have you also seen 2) on windows or just android?

@dessant The second video(issue): Checked now on windows(py2/py3) with sdl2 and master, checked even on android, custom launcher with master branch from 13042016 - nothing. Copied some cyrillic text from wikipedia because I don't have russian keyboard - maybe again only keyboard issue?

The first one however is quite alive on android. No such problems on windows.

I've downloaded the wheel from:
http://www.lfd.uci.edu/~gohlke/pythonlibs/

Probably miss-clicked by the issue, as I use the shortcut for copy a text from textinput, it crashes.
Here's what my log says:

@picibucor, it is an unofficial wheel, not supported by us. I'm not aware of anyone from the team working on shipping a py3.5 wheel, the more likely outcome is that we will wait until mingwpy releases a version which supports py3.5, unless someone from the community steps in and makes kivy work with msvc.

Hello !
I made this post 3.5 years ago, but as I see the problem is not solved. I bought a new tablet with Android 7.0, an error appears in it. I downloaded from PlayMarket KivyShowcase, in this program there is also an error. I tried to work with two built-in keyboards (SwiftKey, Gboard), on both of them there is an error. Unless on Gboard at use of an English layout it is shown much less often. I made a fresh video for illustration https://youtu.be/GqMhwFWR8ХА. With such a problem, the use of Kivy becomes problematic, a minor correction of the text leads to radical changes.
