this is My example code. take a look: https://github.com/Saqib92/capacitor-preview-camera-example

[Reizar]

@Saqib92 I found a solution to this as I ran into it too.

In your module build.gradle ( android/app/build.gradle)

You need to add this to the android section:

buildFeatures {
    dataBinding true
}
dataBinding {
    enabled = true
}

Should look something like this:

android {
    compileSdkVersion rootProject.ext.compileSdkVersion
    defaultConfig {
        .... removed
        }
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

    buildFeatures {
        dataBinding true
    }
    dataBinding {
        enabled = true
    }
}

@Reizar yes you are right, thank you for mentioning that. Probably need to add it to readme.
