The other 2 methods: onCreateOptionsMenu(Menu) and onOptionsItemSelected(MenuItem) are used to create the Menu for this Activity, but we won’t use it in this Application, so you can delete them.
There should be some auto-generated code, but you can leave only the onCreate(Bundle) method. You can close activity_shopping_list.xml and strings.xml. The ShoppingListApp will be installed on your device and should look like this: All the available devices should appear in the Choose Device window, under ‘Devices’. You can either plug in your Android device, or you can create a new Genymotion device and start it. You can run the app to make sure everything works. In this file you will keep all the String values that the user can see. Go to app -> res -> values and open strings.xml.

If you are not sure what API level to choose, you can click on “Help me choose.” and see for each version how many users will be able to use your app. Keep in mind that you cannot run your app on devices that have lower API than the one you choose, but if you choose an API that is too old, you will probably not be able to use all the features you want. Now you need to select the Minimum SDK for your app. Pick a location for your project and click Next. Notice that the Package name will be your domain name backwards.
