An app with two input text field, A and B:
- the A, when you touch, show a screen with keyboard in a English layout;
- the B, when you touch, show a screen with keyboard in a Spanish layout;
I know that I can use different keyboard programs for different app in a root env, but using the same keyboard program with different languages locked for specific fields in the same app, without the need to change manually the input language I don't know if it is possible.
