Form validation library for Android?

Question

Is there any mature form validation API / library for Android? I\'ve found http://code.google.com/p/android-binding/ but it seems that is under heavy development.

Answer 1

I would recommend OVal

public class BusinessObject {

@NotNull
@NotEmpty
@Length(max=32)
private String name;

 ...
}

// collect the constraint violations
List violations = validator.validate(bo);

I'm planing to uses it in my next project since is has a variety of expression languages, but only Java is hard required.

It is not JSR303 compilant, but supports those annotations too.
