Under package name, put the full name of your app package. You can find this information under the AndroidManifest then the package tag.

Example package name:

Hi. How to know what is the "full name" of my package? Can I put anything or does it depend on the project folder? So for example, my project's android folder is `D:\@WORK\personal_projects\android_projects\MyAppName\android`. By default, the package name is `MyAppName`. However, when I run this, it returns the invalid package name error. – akmalmzamri Jan 20 '19 at 02:24

Open the .java file of the Main Activity of your App. The very first line shows the statement starting with the word "Package". Copy the text following the word "Package" excluding it and paste it to the package name while creating the new Activity.

Hope this helps !
