Android 10 crash onfocus

[daniponsg1991]

Dear ks32,

We have upgraded a device to Android 10 and we have noticed that the application crashes when we focus over input-box, textarea, etc.

With other Android versions the application works perfectly.

The exception is:

It seems that the issue is related with the keyboard show process.

Do you have any idea about this issue?

Thanks in advanced.
