Bug in the keyboard event listener

[Neizvestnyj]

• Python: 3.8
• OS: android
• Kivy: 2.0.0, master
• Cython: 0.29.19
• OpenJDK: 8

When I click on the input field, the event handler that is declared in the init method stops working (events like 'back') , but if I switching focus away from the whole app, then back again, the handler starts working until I click on the text field again.

All this I tested with: api: 27, 28, 29, 30 ndk: 19b, 19c, 20b, 21e p4a branch: develop, master, release-2019.06.06, release-2020.06.02

p4a.bootstrap = sdl2 android.arch = armeabi-v7a, arm64-v8a

Well you didn't get an answer there https://github.com/kivy/kivy/issues/7374 So I suppose it doesn't hurt to try here ;)

However I think nobody understands what is going on as shown by:

@RobertFlatt Yes, most likely the problem is with p4a, or rather with sdl, and the bug is old, and not related to Google, they are doing well

Months later, I think this may be due to the event listener not returning a boolean, https://github.com/kivy/python-for-android/blob/develop/doc/source/apis.rst#handling-the-back-button

For my example, this did not solve the problem. But now suggestions works (It's still broken, but at least something). requirements = kivy==master p4a.branch = develop
