View Bindings not generating

Question

I'm currently trying out the new ViewBindings but i'm not getting them to work. I'm on Android Studio 3.6.1. I just created a new project and added viewBinding.enabled = true to my modules build.gradle. But when I try to access the MainActivityBinding class, it says it cannot resolve the symbol. Autocomplete doesn't find anything resembling a binding class. I also tried with a different project using Kotlin but no success there. AS4.0 doesn't help either. What do I need to do to generate the ViewBinding classes?

My build.gradle

apply plugin: 'com.android.application'  android {     compileSdkVersion 29     buildToolsVersion "29.0.3"     viewBinding {         enabled = true     }      defaultConfig {         applicationId "com.example.myapplication"         minSdkVersion 29         targetSdkVersion 29         versionCode 1         versionName "1.0"          testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"     }      buildTypes {         release {             minifyEnabled false             proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'         }     }  }  dependencies {     implementation fileTree(dir: 'libs', include: ['*.jar'])      implementation 'androidx.appcompat:appcompat:1.1.0'     implementation 'androidx.constraintlayout:constraintlayout:1.1.3'     testImplementation 'junit:junit:4.12'     androidTestImplementation 'androidx.test.ext:junit:1.1.1'     androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0' } 

Answer 1

I couldn't find my ViewBinding files until it dawned on me that the bindings were being named after the XML files ("fragment_home.xml") and not after the class ("HomeFragment.kt"). So I couldn't find them at HomeFragmentBinding but I found them at FragmentHomeBinding.

I found it helpful to think of each ViewBinding as a helper singleton that has been created as that XML file's delegate.
