7. ANDROID STUDIO
 IntelliJ Idea Community
 Refactoring, Fixes, Multiple Config Preview

8. ANDROID NDK
 Native Code using C/C++
 Java Native Interface (JNI)
 Android 2.2 Dalvik has a just-in-time compiler
 CPU Intensive applications
 I mean really INTENSIVE…
 Reuse C/C++ code
 Did I mention how INTENSIVE it must be?

11. CORE CONCEPTS
 Activity Lifecycle
 The OS is who decides
if your activity will
be closed or not.
11

12. CORE CONCEPTS
 Activity
 Single focused thing the user is doing.
 It’s generally a whole window.
 A canvas where you layout the app.
 Now, there are Activity Groups.
 Design for Micro-tasks in mobiles.
12

13. CORE CONCEPTS
 Context
 Application Environment
 Language
 Resolution/Density
 Orientation
 Resources
 Strings, Images, Layouts, Colors
 All have specific context
13

14. CORE CONCEPTS
 Intent
 Denotes the intention to open another activity.
 Stack another activity in your app.
 Opens a registered Intent:
 Share Something
 Capture a Picture
 Get a Bar/QR Code
 Send a Text
14

15. CORE CONCEPTS
 Intent Examples:
 Launch Camera:
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);
 Launch Share:
Intent sharingIntent = new Intent(android.content.Intent.ACTION_SEND);
sharingIntent.setType("text/plain");
sharingIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "Subject Here");
sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, "Text Here");
startActivity(Intent.createChooser(sharingIntent, "Share via"));
 Launch Other Activity:
Intent openActivityIntent = new Intent(getApplicationContext(), NextScreen.class);
startActivity(openActivityIntent);

16. ARCHITECTURE PATTERNS
 MVC (Model-View-Controller)
 Views are activities
 Controllers are handlers
 Models are domain
objects
16
Model
View Controller
show
user input

17. ARCHITECTURE PATTERNS
 MVP (Model-View-Presenter)
 Views are activities.
 Presenters retrieve data,
format, display and receive
events.
 Models are strictly
domain objects.
