9. Android
Architecture
● Developed by Google and
OHA (Open Handset Alliance)
2005
● Language used: Java, Kotlin,
Dart, JavaScript, C++, etc
● First version (API Level) is
Android 1.0 (Aestro) in 2008
and the current version is
Android 14 (Upside Down
Cake) in 2023.
● Android is Open Source.
Anyone can customize the
Android Platform.

10. Android Architecture
● Linux Kernel is responsible for device driver, device management, memory
management, etc. It helps mobile apps to communicate with mobile devices
hardwares and use their services such as camera, microphone, touch screen,
etc.
● Native Libraries serves as collection of classes that we can use to create
mobile applications functionality.
● Dalvik Virtual Machine (DVM) is Android runtime. It is a mini version of JVM. It
consumes less memory, thus it is suitable for small device.
● Android Framework is Android APIs in which developers can use to integrate
with Android features such as telephony, location, package managers, etc.
● Application, on top of Android framework is our application. We will learn how
to create our own Android application. SO LET GET STARTED.

11. Environment Setup
● Get the Android Studio
Installer
(https://developer.android.c
om/studio)
● Why Android Studio? It is
the official IDE for Android
applications development.

12. Environment Setup
● Locate the current Java
Development Kit (JDK).
● Download the JDK when it
is not in your device yet.
(https://www.oracle.com/id/j
ava/technologies/download
s/)

13. Environment Setup
● You may include Android
Virtual Device (Emulator)
and Intel HAXM, or you can
instal them later.

14. Environment Setup
● Locate your installation
folder.

15. Environment Setup
● Wait for the extraction
process.
● After the installation. You
may need internet
connection to let Android
Studio auto download the
additional requirement files,
mostly dependency files.

16. Start with new project
● After the installation, we are ready
to create our first Android App.
● Start your Android Studio and
choose Start a new Android Studio
Project.

17. Start with new project
● Name the application and company domain.
● The default language is Java. In this course, we will use Java, so at this step
you do not need to check the Kotlin or C++ support.

18. Start with new project
● At this step, you need to
choose on what
platform your
application will run. In
this course, we focus on
developing Android
phone device or tablet.
● The API level is also
important. You need to
survey your target
audience and decide
what the API used by
the majority.

19. Start with new project
● Choose Empty Activity
● Activity is basic
Android Application
Components.
● There are five
important components.
● We will discuss the
Android Application
Components for a
while before we
proceed with the
project.

20. Android Application Components
● Activity represent a single screen with a user interface. It is something that the
user see on their mobile phone screen. So, basically, most of Android Apps,
are a set of integrated activities.
● Service, on the other hand, does not require a UI. It runs in the background.
For example, user can listen to music while he/she uses another application.
● Broadcast Receiver is a component that respond to the broadcast messages
from other applications or from the system. For example, application
sometimes received notifications from other applications. The broadcast
receiver works to manage the message from one application and distribute to
other applications.
● Content Provider is a component that supplies data based on the application
request. The data can be stored in files or database.

21. Android Application Components
● Intent is an object that contain data from the intent creator that later will be
received by the other process. The other four components used intent to
communicate to each other.
● For example, Activity A create an intent and send it to Activity B. It helps the
user to move from Activity A screen/ UI to Activity B screen/UI.
● We will discuss the detail of Activity and Intent in week 2.
● Let’s go back and continue with the project preparation.

22. Start with new project
● After we choose Empty
Activity from the
previous step, then we
are prompted to create
the first activity.
● First the Activity
Name, it will generate
a java file, while the
Layout Name will
generate xlm file.

23. Get familiar with the
environment
● Once the project ready, you will see the
Android Studio IDE
● On the left side, you could see the project
folder structure panel.
● Manifest Folder contains
AndroidManifest.xml. This file contains
information about our application such as
the Android version, metadata, and other
application components.

24. Get familiar with the
environment
● The Java folder contains all java files. In the project preparation, we set the
name of the activity to MainActivity, thus we see a java file with the same
name.

25. Get familiar with the
environment
● Res folder consist of several
sub folders. The drawable is a
folder where we store all
image files. The layout is
where we can find the xml files
the will define the UI of the
application. Values folder
consists of several xml files.
The strings.xml define all the
label used in the UI. The
colors.xml define the color
code used in the application.

26. Get familiar with the
environment
● The last folder, is Gradle Scripts folder. This folder is important. Gradle script
contains information about our application configuration including all required
dependencies files in order to run our application. A problem in Gradle scripts
may cause failure in application installation, thus the user cannot use the app.

27. Hello World
● As explained earlier. An activity is component that the user see on the screen.
When we choose empty Activity, meaning that we create one activity with
nothing on it. Our activity that we have created previously is named
MainActivity. There are two important files that responsible to handle this
activity.
● MainActivity.java is a java file that is responsible for all the logic, data
processing, class integration, and many more. We can find this file in Java
folder on the project folder panel.
● activity_main.xml is an xml file that is responsible to define the layout type, the
view groups, view elements, etc.
● To create Hello World application, we simply need to add view element in the
layout (activity_main.xml).

28. Hello World
● Add a TextView
element in the
activity_main.xml.
This textview will
content a string
Hello World, that
later will be
displayed on the
user screen.

29. ● The layout_width and layout_height both set as “wrap_content”. It means that the
width and the height of the TextView will depends on the size of the content.
● The layout_constraint for all position (bottom, left, right, and top) are all set to
“parent”. It means that the position of the TextView is follow the parent setting.
● The text = “Hello Android!” is a string or label that appear on the user screen.

30. Hello World
● The
MainActivity.java
is responsible for
to execute the
layout
(actvity_main.xml),
so that the user
will see what is in
the layout when
the activity is
started

31. ● In the MainActivity.java, there is a method called onCreate. This method is
called when the activity is created, basically when the user run the application
at the beginning.
● This method then call the layout to appear on the screen using the
setContentView(R.layout.activity_main) function.
● R.layout.activity_main is the path of the xml file. The activity_main.xml is located
in res/layout folder

32. Hello World
● Click Run, then we will see the result
● If your Android Virtual Device (AVD) is
not ready, then we need to add the
AVD in the Android Studio

33. Android Virtual Device
● Android Virtual
Device (ADV)
work as emulator
to run and test our
application.
● In order to add
Open Device
Manager and
Click Create
Device

34. Practice
● Create another Android Project.
● Choose Empty Activity
● Name your project with your studentid_01
● Create an application that showing your image profile and information such as
names, studentid, email, major, address, dob, hobbies, and your picture profile
● Test your app using AVD.

35. Thanks and
See you next week
