Publishing to Google Play

What are some things that you think should be done before you publish to your app to Google Play?

Debugging

• We've covered debugging previously

• If you don't know how to debug at this point, that's my fault.

Preparing Your App

Test your application extensively on an actual device

• �JUnit and other test cases.

• UI/Application Exercise Monkey

UI/Application Exercise Monkey

• The Monkey is a command-line tool that you can run on any emulator instance or on a device

• It sends a pseudo-random stream of user events into the system, which acts as a stress test on the application software you are developing.

UI/Application Exercise Monkey

• The Monkey includes a number of options, but they break down into four primary categories:

o Basic configuration options, such as setting the number of events to attempt

o Operational constraints, such as restricting the test to a single package

o Event types and frequencies

o Debugging options

UI/Application Exercise Monkey

• If your application crashes or receives any sort of unhandled exception, the Monkey will stop and report the error

• If your application generates an “application not responding error”, the Monkey will stop and report the error

UI/Application Exercise Monkey

e.g.

$ adb shell monkey -p your.package.name -v 500

What do you think are some Things That Cannot Change after you first publish an app to the market?

Preparing Your App

Choose a good package name!

Things That Cannot Change

Preparing Your App

Test your application extensively on an actual device

• �JUnit and other test cases.

• �UI/Application Exercise Monkey

• Obtain one or more physical devices �Run it under realistic network conditions �Can verify that the UI elements are sized correctly �Can check that your performance and battery efficiency

are acceptable

• �Testing your Application

Preparing Your App

• �Consider adding an End User License Agreement in your application

o To protect your person, organization, and intellectual property, you may want to provide an End User License Agreement (EULA) with your application

• http://bees4honey.com/blog/tutorial/adding-eula-to-android-app/

Preparing Your App

• �Consider adding support for Android Market Licensing

o This is optional.

o �If you are publishing a paid application through Android Market, consider adding support for Android Market Licensing.

Preparing Your App

• �Consider adding support for Android Market Licensing

• With Google Play Licensing, your application can query Google Play at run time to obtain the licensing status for the current user, then allow or disallow further use as appropriate

• an application can o check the licensing status and then apply custom constraints that

allow the user to run it unlicensed for a specific validity periodo restrict use of the application to a specific device, in addition to any

other constraints.

• More on Licensing

Preparing Your App

• �Specify an icon and label in the application's manifesto The icon and label that you specify in an

application's manifest are important because they are displayed to users as your application's icon and name

o �They are displayed on the device's Home screen, as well as in Manage Applications, My Downloads, and elsewhere.

o Additionally, publishing services may display the icon and label to users.

o �Define the attributes android:icon and android:label in <application> element in the manifest.

Preparing Your App

• �Before you do the final compile of your application

Version your application• Before you compile your application, you must make sure that you

have defined a version number for your application, specifying an appropriate value for both the android:versionCode and android:version Name attributes of the <manifest> element in the application's manifest file.

• Carefully consider your version numbering plans in the context of your overall application upgrade strategy.

• If you have previously released a version of your application, you MUST make sure to increment both the Version Code and Version Name Attributes.

• �Versioning your Application

Preparing Your App

• �Before you do the final compile of your application

Version your application

<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.package.name" android:versionCode="2" android:versionName="1.1">

<application android:icon="@drawable/icon" android:label="@string/app_name">

... </application></manifest>

Preparing Your App

Next, you need to

• Obtain a suitable private key

• Compile your application in release mode

• Sign your application with your private key

• Align the final APK package

Do you want to learn how to do this via the command line?

• Signing your application

Preparing Your App

To do this in Eclipse

• File > Export > Export Android Application

To get an idea of what values you should enter in the form, look at the sample values used on the command line here
