Finishing my first Application

1. Toast Notifications
2. Log/debugging
3. Getting ready for Google Play

1. Toast Notifications: these are limited popup notifications that fade in and out automatically. They do not require user input. Things to consider before reading: Gravity is a method that allows you to manipulate the area you want to set the toast. Because we are using static , we do not need to use the new keyword. This refers to the current class you are referring too.

1. Toast notifications

How to make it with 3 lines

• String toastMessage = "Yay! Our acitivy was created!";
• Toast.makeText(this, toastMessage, Toast.LENGTH_LONG);
• welcomeToast.show();

How to make it in two lines:

• Toast.makeText(this, "Yay! Our Activity was created!";
• Toast.LENGTH_LONG).show();

How to manipulate the toast to make it show up where you want it on the  screen:

• Toast welcomeToast = Toast.makeText(this, "Look here!", Toast.LENGTH_LONG);
• welcomeToast.setGravity(Gravity.TOP,0,0);
• welcomeToast.show();   

2. Debugging

• Logs: helpful information of why an application has crashed
• writing data to the log and how to view the log
• use logcat view
• e: errors, w: warn, i: info, D: Debug, v: verbose      

• log.d("TAG", We're logging from the onCreate() method!");
• public static final String TAG = MainActivity.class.getName(); 

Google play steps:
1.  Develop the app
2.  Sign up for a publisher account on Google Play
3.  Sign up for a publisher for a one time fee of 25 dollars.
4.  Fill out a form to add a new app to your account.
5.  Publish the application(No review process)

*Google gets 25% of profits from the app(you get 75%)

Cannot let com.example.crystal.ball on Google Play, must change example name.

i.e. com.MichaelTo.crystalball

Publishing on Google Play => build the release ready APK => has debut certificate

private Digital Signature

go to file = > export = > expand android = > create new keystore
 * You usually have one keystore for all applications which holds your private key to sign into all apps.

i.e.  Doan.keystore   pw: KidKuddi  alias: Doan_key

Upload application => choose file => open(crystalball app)  => upload

Create screen shots by using the DDMS perspective view: select emulator and camera, icon ==> save

Now you're done.
