Enabling data binding

By default in an Android project, the data binding capabilities are turned off. You'll need to enable them in your project's build.gradle file by hand. Follow these quick steps to enable the data binding system:

1. Start by locating the build.gradle file for your application module in the Android panel in Android Studio:

2. Open this file and locate the android block:

android {
  compileSdkVersion 26
  // ...
}

3. At the end of the android block, add the following snippet to enable data binding:

android {
 compileSdkVersion 26
   // ...
   dataBinding {
      enabled = true
   }
}

4. Once you save this file, Android Studio will open a banner at the top of the file, telling you that it needs to sync the project. Click on the Sync Now link on the right-hand side of the banner and wait for the sync to complete.

Congratulations! You've just enabled the data binding framework on your project. Now you can get started, making use of the data binding system in your layout files, which will simplify...
