回答1:

I looked for many solution and finally i found that problem was in one of Dependencies, So I removed this kapt "com.android.databinding:compiler:$gradle_version" from app.gradle and project run succeffully.

回答2:

As of Android Studio 3.2, this kapt plugin is no longer required.

However, without this plug in, the error message in case of any error, while compiling is cryptic. So, only option now it seems now is to downgrade your Gradle version to 3.1.4.

Thanks to article at http://mobiledevhub.com/2018/01/05/android-two-way-databinding/

The answer is pretty simple:

just add these lines in gradle app

//Data binding
dataBinding.enabled = true

and remove these two lines :

 apply plugin: 'kotlin-kapt'
 kapt "com.android.databinding:compiler:$gradle_version"
