Versions

• CLI: 3.4
• Runtime: 3.4

Steps to reproduce

1. Create {N} app

tns create testapp

2. Declare custom activity somewhere in the app.

// ./app/MyActivity.js
android.app.Activity.extend("com.tns.MyActivity", {
    onCreate: function (bundle) {
        this.super.onCreate(bundle);
    }
});

3. Build the app

   tns build android
   

   The proxy class will be generated in platforms/android/app/src/main/java/com/tns/MyActivity.java.
4. Delete the custom activity

rm ./app/MyActivity.js

5. Rebuild the app

tns build android

The generated class won't be deleted and will be present inside the built .apk as well.
