bugs

if you clone the repo there should be no issues, but if you for some resone need to reset the app resources, please check the below issues

there is a 'Duplicate class com.google.zxing.qrcode.encoder.QRCode found in modules core-3.3.0.jar' bug that arises from using the above 2 plugins , 
the solution is to add to your /app/App_Resources/Android/app.gradle

  configurations {
    compile.exclude group: 'com.google.zxing'
  }
  
My full app gradle is :
android {
  defaultConfig {
    minSdkVersion 17
    generatedDensities = []
  }
  aaptOptions {
    additionalParameters "--no-version-vectors"
  }
  configurations {
    compile.exclude group: 'com.google.zxing'
  }
}

if you still get an error try this :
open up where the plugin was installed (node_modules/nativescript-zxing) and then delete the platforms/android folder inside my plugin.
