尝试使用视图绑定时出现 groovy.lang.MissingMethodException

Question

I'm working on a big project and I'm trying to add view binding using two different aproaches:

First aproach:

buildFeatures {
    viewBinding true
}

Second aproach:

viewBinding {
    enabled true
}

On both cases I get a Caused by: groovy.lang.MissingMethodException: No signature of method: build_4xgux05b5phesnrai6p6fg7vc.android() is applicable for argument types: (build_4xgux05b5phesnrai6p6fg7vc$_run_closure3) values: [build_4xgux05b5phesnrai6p6fg7vc$_run_closure3@5e534db6]

I am putting this inside android { } on my module:app.

Any idea why this might be happening?

Answer 1

You need to increase android gradle plugin version to 3.6.0 (or higher):

// Android Gradle Plugin 3.6.0
android {
    viewBinding {
        enabled = true
    }
}

Or:

// Android Gradle Plugin 4.0
android {
    buildFeatures {
        viewBinding = true
    }
}

I was having the same issue on my Android Studio, what I did to fix it was this:

Before the

android { 
   ...
} 

I check the plugins fields, ie:

plugins {
    id 'com.android.application'
    id 'kotlin-android'
    id 'kotlin-android-extensions'
    id 'kotlin-kapt' <- this one is when you need to use databinding I think
}

For my case to fix this issue I just add the line

id 'kotlin-android-extensions'

And all works as expected, hope this answer would be useful for your problem
