AndroidDataBinding

Now very easy to bind data and it's view (data binding) in android

Download APK :

Its have just a few steps :

Benifits:

1. Data binding can lead to faster development times
2. Faster execution times (more then findviewbyid)
3. Stronger readability (More readable and maintained code).
4. Remove boilerplate code

Drawback :

1. Auto generated class (it's true it will increase the app size)
2. Hard to debug - depends, like readability, of what you are used to.

Add the dataBinding element to your app build.gradle file to enable Data Binding.

 android {
dataBinding.enabled = true
}
