3. ❏ Creating a project step by step
explanation
❏ Your first app using Android Studio on
Ubuntu 14.04
Contents

4. ❏ File → New Project. Type the name of the project as shown in the
screenshot.
Steps

5. ❏ Application Name: Name of the application that you want to create. It
will appear along with the icon on the phone. So please use a short
name which will be visible.
❏ In the second screen, please choose the Minimum SDK. You can also
decide whether you want to create a build for TV and Wear also.
Minimum SDK means the minimum version of the Android OS which
you app will support. For example if you create an app for Ice Cream
Sandwich it will run in Jelly Bean, KitKat and Lollypop. But if you
create something in Lollypop, it will not be compatible with previous
versions. Also you can not go for Froyo or Cupcake as there are many
changes done in the later releases and functionality will be very less in
the previous versions. So the best way is to go to the Google Play and
find out the distribution of the OS and then decide which build you
should go for based on the geography.

7. ❏ In the next screen, select an activity. Activity means a screen in your
app. Every screen in Android is usually an activity (At beginner level it
is better to understand like this. )
❏ You must have an activity for the app.
❏ For now, I have chosen a Blank activity.

8. ❏ Activity Name: Name of the activity to load.
❏ Layout Name : Every screen (activity) UI is designed using an XML File. This
Layout will define the layout of the activity.
❏ Title : It is the title of the activity. In the case of blank activity, it is not required. It
is used only in the case of Map Activity. In the case of MAP activity the Title Bar
and this title is same.
❏ Menu Resource Name : This file will decide what should be displayed when the
user clicks on the Menu of the android app screen.

9. Check whether the setup is correct
❏ Click on the Run → Run (Alt + Shift + F10)
❏ Studio will ask you to Choose a Device. You need to create a virtual android
device. Please note that the android device which you create must have an
operating system equal to or newer version than what you have selected while
creating the project.

10. Creating a device (Android Virtual Manager)

11. Now you can create your own device from the list of the devices. You can go to advanced
settings if you have 2 or 3 GB Ram as by default the AVD will allocated 512 MB RAM. You can
reduce it to 256 MB RAM if you are not creating high end applications.
Click on Create Virtual Device (Bottom Left
corner)

12. I launched the application with Nexus 5
