Main downside of native installation

Main downside of native: installation

  • Mobile web apps are trivial to distribute

    • Open browser, go to URL, bookmark to home

  • Native mobile apps are a pain to distribute

    • You need a license to create and distribute

    • You need to deploy to app store

    • You need to wait for approval

    • Users need to find, choose, approve, install app


An overview of distribution

An overview of distribution

  • The goals of this lecture are to…

    • Summarize the main challenges of distribution

    • Reveal important differences between distribution of Android and iOS apps

    • Give some guidance about how to distribute

  • But the lecture is a "snapshot in time"

    • Distribution processes can and do change

    • Expect that you will have to adjust with the times


Ios development restrictions

iOS Development Restrictions

  • Every app developer must be identifiable

    • Individual developers are identifiable by the credit card number that they use

    • Companies are identifiable by DUNS number (registered with the US Federal Government)

  • Every app’s developer must be identifiable

    • Through public-key certificates

  • Every app must be approved before app store

    • Reviewed for appropriateness in the app store


Putting apps on your own iphone

Putting apps on your own iPhone

Apple Developer Registration (free)

Apple WWDR (identifies Apple) (free to download)

iOS Developer Registration ($99)

iOS Distribution Certificate (identifies you)

Provisioning profile (links all three)

Device registration (identifies iPhone)

App ID registration (identifies apps)

Used to install apps on device


Basic steps for getting registered

Basic steps for getting registered

  • Go to developer.apple.com > Member Center and register as an Apple Developer (free) so you can log in

  • Once logged into the Member Center, sign up as an iOS Developer (not free)

    • Pay your $99 by credit card

    • Wait 24-48 hours (yes, really)


Continuation of previous slide 3 create ios distribution certificate

(Continuation of previous slide)3. Create iOS Distribution Certificate

  • The Distribution Certificate is Apple’s permission for you to install apps on devices

  • Needed for installation onto your own device (aka ad hoc distribution) or via the app store

  • Last time I checked, these steps are documented at developer.apple.com/ios/manage/distribution/


Continuation of previous slide 3 create ios distribution certificate1

(Continuation of previous slide)3. Create iOS Distribution Certificate

3.1 On Mac, use Spotlight to open Keychain

3.2 In Keychain, set preferences OSCP=Off, CRL=Off

3.3 In Keychain, use Certificate Assistant to request a Certificate (2048 bits, RSA), save to hard drive; this is called a Certificate Request

3.4 Go to the Member Center > iOS Provisioning Portal

3.5 Select Certificates section, Distribution tab, upload the Certificate Request. Wait 10 minutes.

3.6 Approved certificate should appear on Development tab.


Continuation of previous slide 3 register a device

(Continuation of previous slide) 3. Register a device

  • You have to register every device that you want to install onto via ad hoc distribution (i.e., by sending the binary via email, iTunes, and USB)

    3.1 Go to the Devices section of the Member Center

    3.2 Create a new Device entry, with a memorable name and the UUID

  • You can find the device’s UUID in iTunes

    • Hook it up

    • Go to iTunes

    • Click on the Serial number so that it mysteriously changes into the UUID (seriously)


Continuation of previous slide 4 register an app id

(Continuation of previous slide) 4. Register an app id

  • App ids identify the developer of apps.

  • App id = Team ID (you) + bundle id (group of apps)

    4.1 Go to the App IDs part of the Member Center and create a new App ID

    4.2 Important: your Bundle ID (second half of the App ID) should have the form XXXXX.YYYYY.*

    example: com.titaniumbits.*

    This will let you create many apps, each of whose names will start with “XXXXX.YYYYY.”


Continuation of previous slide 5 create a provisioning profile

(Continuation of previous slide)5. Create a provisioning profile

  • Provisioning profile links you (i.e., your Certificate) with a device (or the app store) and with a group of apps (bundle).

    5.1 In the Provisioning section of the Member Center, create a new Provisioning Profile

    5.2 For development on your own device, use the Development Tab.

    5.3 For app store distribution, use the Distribution tab.


Continuation of previous slide 6 install on your machine

(Continuation of previous slide)6. Install on your machine

6.1 Download certificates: your own, and the WWDR (basically a key identifying Apple)

6.2 Download provisioning profile

6.3 In Finder, double-click the WWDR Certificate to import it into keychain. Now your Mac trusts Apple. Then double-click your own Certificate to import.

6.4 In Titanium Studio (or xCode), create a new project with an appid of the form XXXXX.YYYYY.ZZZZZZZZ

6.5 Run the app on “iOS Device”. When prompted, provide the provisioning profile you downloaded


Distributing to app store

Distributing to App Store

1., 2. Register – you already did this

3. Generate another Distribution Certificate – this one, for the app store

4. Create an appid – you already did this

5. Create another Provisioning Profile – this one, for app store (using new Distribution Certificate)

6. Install the Provisioning Profile in Titanium Studio (or xCode)


Continuation of previous slide 7 set up app on itunes connect

(Continuation of previous slide) 7. Set up app on iTunes Connect

7.1 Go to Member Center, to iOS Provisioning Portal, then the iTunes Connect portal

The first time you do this, you’ll be prompted to accept the iTunes Connect terms of service

7.2 Go to Manage Apps and create an app entry

7.3 View details (near bottom of screen) and confirm it is ready for upload


Continuation of previous slide 8 build and upload to app store

(Continuation of previous slide)8. Build and upload to app store

8.1 Build for distribution

8.2 Xcode Organizer opens. Go to the Archives

8.3 Select app and click validate against your app entry in the iTunes Connect site

- If it says no suitable app record found, then you might not have a matching app name, id, version

8.4 If the validator complains, fix the problems

- Probably have to create some additional icons (see next slide)

8.5 Click submit button to commit to app store


Continuation of previous slide 8 4 fixing those icons

(Continuation of previous slide)8.4 Fixing those icons

  • If you are using Titanium Studio, then it probably will mess up your icons.

    • Go to your project in Finder

    • Go into the Resources/iphone subdirectory

    • Double-click your appicon.png to open in Preview

    • Use Tools > size to resize to 114 x 114

    • Use File > export to save a copy as [email protected]

    • Use Tools > size to resize to 72x72

    • Use File > export to save a copy as appicon-72.png

    • Exit Preview


Continuation of previous slide 8 4 fixing those icons1

(Continuation of previous slide)8.4 Fixing those icons

  • Go back to Titanium Studio

  • Copy the build/iphone/Info.plist file to the same directory as your tiapp.xml file

  • Open the Info.plist file for editing in Dashcode

  • Add appicon-72.png to the list of icons

    <array>

    <string>appicon-72.png</string>

    <string>appicon.png</string>

    <string>[email protected]</string>

    </array>

  • You may need additional icons as more kinds of devices are invented (i.e., retina and beyond)

  • Rebuild and revalidate

Android development restrictions

Android Development Restrictions

  • Every app developer must be identifiable

    • Developer accounts are identifiable by the credit card number that they use

  • Every app’s developer must be identifiable

    • Through public-key certificates

    • But your signature isn’t actually registered with Google, so it doesn’t do much

  • Every app must meet basic marketing rules

    • No actual checks on the code that you write
