It is so easy guys, just don’t forget that DataBinding creates a field called context which you can access by default in your XML file. So you can write something like this:
<data>
<variable name="name" type="String"/>
</data>
<layout>
<TextView
app:text="@{StringUtils.format(context, name)}" />
</layout>
And it will be just fine. You have the context from the parent view. Check it HERE.
There is a very simple solution in Android if you want to have space between components. You can always set margins but you can also use the Space class. You can use it like this:
<Space android:layout_width="1dp" android:layout_height="30dp"/>

I had to implement a feature toggle recently.
I will keep it short. You have to add a new feature to your product, but you want that feature to be available only for certain type of users. What you do? Well, you just make an if check to see the user can see this feature and then you toggle it for him. Here is a sample check:
if(ToggleRouter.isEnabled("comments")) {

That means that I have several routes like: “/admin”, “/login”, “/users” and I want the admin route to be accessed only from admins, login to be accessed from admin and users and the users route to be accessed from only the users.

It keeps the validation logic separate and isolated from the controllers and other stuff. So I was wondering how to integrate Joi with Sails.

The problem is that the library can only be used as a separate module. You can call the card.io Activity and it will return you the results from the detection. But what if you want to embed the detection view inside your app? Well, sadly, there is no fragment for that. But the library is open-source so you can change everything to fit your needs. So let’s start then!
