Develop Android apps with Kotlin
• Kotlin merupakan Bahasa Pemrograman modern yang bersifat statically-
typed yang dapat di jalankan di atas platform Java Virtual Machine (JVM).
• Kotlin juga dapat di kompilasi (compile) ke dalam bentuk JavaScript
• Dibuat oleh JetBrains yang juga mengembangkan salah satu tools
pemrograman (IDE) yang saat ini di adopsi oleh google untuk di gunakan
sebagai tools pengembangan aplikasi di Android (Android Studio).

Android Studio is the official Integrated
Development Environment (IDE) for
Android app development, based on
IntelliJ IDEA

13.
All the build files are visible at the top level
under Gradle Scripts and each app module
contains the following folders:
1. manifests: Contains the
AndroidManifest.xml file.
2. java: Contains the Java source code files,
including JUnit test code.
3. res: Contains all non-code resources, such
as XML layouts, UI strings, and bitmap
images

1. The toolbar : running your
app and launching Android
tools.
2. The navigation bar helps
you navigate through your
project and open files for
editing.
3. The editor window is where
you create and modify
code.
4. The tool window bar runs
around the outside of the
IDE window
5. The tool windows give you
access to specific tasks like
project management,
search, version control, and
more.
6. The status bar displays the
status of your project and
the IDE itself, as well as any
warnings or messages.

15.
To navigate transitions between stages of the activity lifecycle, the
Activity class provides a core set of six callbacks:
1. onCreate() : fires when the system first creates the activity
2. onStart() : makes the activity visible to the user, as the app
prepares for the activity to enter the foreground
3. onResume() : When the activity enters the Resumed state, it
comes to the foreground, and then the system invokes the
onResume() callback
4. onPause() : handles to sensors (like GPS), or any resources that
may affect battery life while your activity is paused and the user
does not need them
5. onStop() : When your activity is no longer visible to the user.
6. onDestroy() : is called before the activity is destroyed. The
system invokes this callback either because:
a) the activity is finishing (due to the user completely
dismissing the activity or due to finish() being called on the
activity), or
b) the system is temporarily destroying the activity due to a
configuration change (such as device rotation or multi-
window mode)

• Fragmen mewakili perilaku atau sebagian UI pengguna dalam FragmentActivity. Anda
dapat menggabungkan beberapa fragmen dalam satu aktivitas untuk membuat UI multi-
pane dan menggunakan kembali fragmen dalam beberapa aktivitas
• Sebuah fragmen harus selalu di-host dalam suatu activity dan lifecycle fragmen secara
langsung dipengaruhi oleh lifecycle activity host.

•All view groups include a width and height
(layout_width and layout_height), and each
view is required to define them.
•wrap_content tells your view to size itself to
the dimensions required by its content.
•match_parent tells your view to become as
big as its parent view group will allow.

19.
• LinearLayout is a view group that aligns all children in a
single direction, vertically or horizontally. You can
specify the layout direction with the android:orientation
attribute.
• A larger weight value allows it to expand to fill any
remaining space in the parent view. Child views can
specify a weight value, and then any remaining space in
the view group is assigned to children in the proportion
of their declared weight. Default weight is zero.
android:layout_weight
