I don´t understand ID app and signed

I don´t understand that I have to put in ID

I have to invent the id?

The other question is, in crosswalk there is an option that says sign the app.

If I select that option the application is now ready to be published??

Google translate

Are you compiling your app in Intel XDK?

If yes, ID is the name of your app as an inverted URL, like "com.yourcompany.yourapp".

And you need to sign your app to can publish it.

Yes ,I use intel XDK.

Ok,which that means the option "signed"that appears on intel XDK??

Then the ID is a URL , but I am an amateur developer and I haven´t website.

Yes ,I use intel XDK.

Ok,which that means the option "signed"that appears on intel XDK??

Yes, enable the "Signed" option to sign your app and publish it in an app store like Google Play.

You don't need necessarily to have a website to publish your app. E.g., you can to use something like "com.caracul.yourapp".

Ok. thank you very much.
