I am having a problem with my original program when upgrading to version 11.

You need to upgrade to B4A v 11.2, install a fresh SDK and then solve the problem with your code. Post the problem on the forum to get help with it. There is no point in using an old and unsupported version of B4A. Those of us who advise on the forum are all running the latest version.

Thank you so much for your advice. Indeed, I am stuck with the old version and yes, I'll try to recode my program using the latest version.

Congratulations and thanks for such a great library!

In the spanish keyboard (it happens the same in many languajes) there are for example vowels (a, e, i, o, u) that can have or not an accent. In the Android original keyboard, if you hold the tab action on a vowel, then an extra floating window appears where you can then select the vowel with different accents...

Can this be done with this library?

At the moment I have not thought of this option. But I will take this into account in future updates
