Question 1

How to set up Convalida with Kotlin and Data Binding?

Accepted Answer

Add convalida-runtime and convalida-compiler dependencies, use kapt for annotation processing, and integrate validation rules in your Data Binding layouts or ViewModels for real-time feedback.

Question 2

Convalida vs Android's built-in validation like TextInputLayout?

Accepted Answer

Convalida offers compile-time safety and flexible integration options, while Android's built-in solutions are simpler but lack advanced features like custom validators or Data Binding hooks.

Question 3

Does Convalida support asynchronous validation, like network checks?

Accepted Answer

Not out-of-the-box; you'd need to implement custom validators with async logic, as the library focuses on synchronous field validation without native coroutine support.

Question 4

How to display error messages with Convalida in a RecyclerView?

Accepted Answer

Bind validation results to your adapter items using Data Binding or the Kotlin DSL, then update UI elements manually since Convalida doesn't provide pre-styled error components.

Question 5

Is Convalida compatible with Java projects or only Kotlin?

Accepted Answer

Yes, it fully supports Java through annotations and Data Binding, and the Kotlin DSL is optional, making it versatile for both language preferences.

Question 6

What happens if the Convalida website documentation is down?

Accepted Answer

You'd rely on the basic README and source code, which might be insufficient for complex use cases, highlighting a dependency on external resources.
