  1. Click InputField : Keyboard show
  2. Click background : Keyboard hide
  3. Click InputField : Keyboard not show

if you click background twice and then click InputField, Keyboard will show.

I tried 2017.4.21 and 2017.4.34, there’s no this problem.
I replace 2017.4.40’s unity-classes.jar with 2017.4.34’s in android project, this bug disapeared.
Is this operation safe? Or I should use old version Unity?

Here’s the simplest project, only one defalt InputField in scene
You can run this apk

It’s not safe, since Unity’s native layer might call something from unity-classes.jar or vice versa, and if something mistmatches, the app will crash, but if it works - it works.

Also 2017 version is no longer supported, 2018 support is also ending in few months, it might be worth to switch to 2019.
