  1. Pour ne pas perdre du temps, commencez à lancer l’installation d’Android Studio si ce n’est déjà fait sur vos machines en téléchargeant au choix depuis :

  2. La dernière version d’Android Studio au moment de rédiger ce support est la 4.0.2 mais ce support de cours utilise les éléments (menus, captures d’écran, etc.) de la version 4.0.2.

2. Big Picture

A unique aspect of the Android system design is that any app can start another app’s component.

2.6. Messages

Try to avoid "Hello JMB!":

Bad: using string "hard coded"
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    ...
    <TextView android:text="Hello JMB!" android:layout_width="wrap_content"
        android:layout_height="wrap_content" />
</RelativeLayout>

Use "@string/message" instead:

Bad: using string "hard coded"
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    ...
    <TextView android:text="@string/message" android:layout_width="wrap_content"
        android:layout_height="wrap_content" />
</RelativeLayout>
String.xml
<resources>
    <string name="app_name">My First App</string>
    <string name="action_settings">Settings</string>
    <string name="message">Hello JMB!</string>
</resources>

2.7. content_main.xml

content_main.xml is a kind of Layout.

content_main.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    ...
    <TextView android:text="@string/message" android:layout_width="wrap_content"
        android:layout_height="wrap_content" />
</RelativeLayout>

2.8. Views

A Layout contains components (buttons, etc.) ⇒ Views

View structure

2.9. Intent

Activities communicate through Intent.

In the same app:

Or between apps:

Intent b/w apps
