Just wait till Its Process is Finished. The first screen you see is Manifest.xml file needs for Android App Startup and store all activity startups and permissions and much more.

You see “com.nulledsourcecode.firstapp” this is the app package name required to publish the app on the play store. this is also called the unique app id of our Project .

The next screen is MainActivity.java file Java files contain programmatic codes to run The app.
