How to change the name of the compiled application?

Good evening! I realized that they did not answer the question and I had this same problem. I found the solution and came to share.

Visit your AndroidManifest.xml for your project. It is one of the last items of your project. After opening, locate in the Application the following description: "android: label=" @ string / app_name ".

By holding Ctrl and clicking "@ string / app_name", you are automatically directed to the Strings page, where you can change the name of your Application. The same thing applies to your app icon or theme.

I hope the solution helps other people.

Sincerely.
