I'm not able to run my project after ugrading from NS from 3.4.0 to 4.1.0 :

Warning: there already is an extend called com.tns.NativeScriptActivity.
Warning: there already is an extend called com.tns.FragmentClass.
Exception in thread "main" java.io.IOException: File already exists. This may lead to undesired behavior.
Please change the name of one of the extended classes.

Hey @essadek,
Few more questions:

Are you using the nativescript-dev-webpack plugin to bundle you app.
Do you have workers in your code?

You might want to check out https://github.com/NativeScript/android-runtime/issues/778. It looks like a similar problem especially if the answer of 1. is 2. is "yes".

Are you using the nativescript-dev-webpack plugin to bundle you app.

check my package.json

Do you have workers in your code?

No I don't use workers at least for now

@essadek please try resetting your project by removingnode_modules, platforms and hooks folders and then rebuild the project. If that does not solve the issue can you please share the entire content of dependencies and devDependencies of your project.

I was getting the same error and issue was that I was using this bit of code android.webkit.WebViewClient.extend({...}): and more than one places. So seems like this error comes up when extending a class with same name or in the above fashion with .extend({}).

I didn't know how do I rename class in the case of .extend({}) (if anyone knows please share) so I removed this from other place to fix the issue.
