Bundle
Check if the bundle is null!
Bundle bundle = new Bundle();
bundle.putString("fname","John");
bundle.putString("lname", "Doe");
bundle.putInt("age", 18);
intent.putExtras(bundle);
startActivity(intent);

9. Explicit Intent vs Implicit Intent
When do you want to use explicit intent
When do you use implicit intent
Intent Filters

10. Fragments Removing and Replacing fragments Fragments
Neither a view nor activity
One activity can have multiple fragments
OnCreateView() returns a view.
How to pass data between activity and fragment
SetArguments(bundle) and getArguments()
Class public member variables
Removing and Replacing fragments

11. Permissions and BroadcastReceiver
When should you use BroadcastReceivers?
Override the onReceive() method
How to statistically register your BroadcastReceiver?
How to dynamically register your BroadcastReceiver?
When do your register
When do your unregister

12. Dialogs and Menus SharedPreference Dialogs Menu
optionMenu
contextMenu
SharedPreference
Why do you use sharedPreference
How to access to your sharedPreference

13. Notifications
What is a notification
When do you use notifications?

14. Service What is a service? Service Lifecycle
Perform a longer-running operation
Running in the background
The service and the UI activity share the same process
Service Lifecycle
onCreate(), onStartCommand(), onDestroy(), etc
Service and IntentService.
When do you use which?

15. Service Messenger is parcelable, so it can be put in a bundle.
How to communicate between service and activity
Broadcast Intent
Pending Result (onActivityResult())
Messenger
Messenger is parcelable, so it can be put in a bundle.
Override handleMessage(Message msg)

16. Async Task Multi-threading
Allows you to perform background operations and publish results on the UI thread without having to manipulate threads and/or handlers.
Easy the use of main UI thread
Publish the result to the UI when it is needed.
What is the difference between using service and Async task?

17. Async Task Multi-threading

What is the difference between using service and Async task?

18. Bound Service What is a bound service and how to use it. Ibinder
Messenger

19. StartActivity and GetResult
startActivityForResult(intent, PICK_REQUEST);
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == PICK_REQUEST) {
