Managing Demo / Full version of my app in Codename One

问题

I was ordered to deliver an app in 2 versions : one demo/light (limitted features) the other full (all features). I have a boolean in code which tells which one is running. They both run as expected in the simulator or on a test device (iOS and Android).

Now I want to distribute them. So I read that it was possible with XCode to define different targets corresponding to the light / full versions and with Eclipse it was possible to define the base project as a library and then create 2 projects also corresponding to the light / full versions.

Before I start messing around with my app project, is there a recommended way to achieve my goal with CodenameOne maybe via build hints that would change the app name and the boolean inside the code depending on a build hint value ?

EDIT 19/09/2016 (working methodology)

Following Shai's advices here are the steps I followed to generate a light version based on the full one (in case someone encounters the same case) :

Under your IDE (Eclipse or whathever) copy and paste the base package in the src folder and rename it com.packageLIGHT.appName (simply append LIGHT to the package name, don't use underscore or space since it will be considered as an illegal character later by Apple)

=> So now in src folder you should have

src

|- com.packageLIGHT.appName

|- com.package.appName

Then in com.packageLIGHT.appName remove all files except MyApp.java (aka the main file). In this file add import com.package.myApp.*;

3.1. (ECLIPSE) In "Run/Run Configurations" menu copy the existing config and paste it as Simulator_MyAppLIGHT and in arguments change it to "com.packageLIGHT.myApp.MyApp".

3.2. (NETBEANS) The "Run/Set Project Configuration" does not seem to work as expected since any configuration that might be selected leads to the same default behaviour. However applying step 6. and running the project in the simulator afterward has the expected result.
Now you should be able to run both versions by running the different configurations.
For iOS (not sure if it is also needed for Android) you have to generate another pair of provisioning files. So move the existing ones in iosCerts/FULL and use CN1 wizard to generate the "light" version provisioning files where you'll adapt the package name to match "com.packageLIGHT.myApp". Store the generated files in iosCerts/LIGHT. There is no need to overwrite the existing certificates (more on certificate here).
Finally replace in "codenameone_settings.properties" the original package name with the "light" one for the lines codename1.ios.appid and codename1.packageName. Also change the iOS provisioning files to iosCerts/LIGHT or FULL depending of what you want to build.
Now when you send the Android / iOS build to CN1 server it will build either the "light" version or the full one depending on what package is written in "codenameone_settings.properties".

Please note : if at step 6. you get NullPointerException on build.xml on line 469 (android build) or 344 (iOS build) which deals with certPassword="${codename1.android.keystorePassword} (android build) or appid="${codename1.ios.appid}" (iOS build) and you're using CN1 plugin version 1.0.0 20160812 under Eclipse then Shai's comment below may be worth it

回答1:

If you want 2 distinct versions of the same app then you need 2 distinct packages since the thing that defines the app uniquely in the store is the app package. There are two common ways to do it:

Place functionality in cn1lib and build two apps
Build one app and just swap the codenameone_settings.properties file

The first one should be pretty clear but might be a bit painful to work with as you can't run the cn1lib and might run into issues debugging it.

The second one is actually rather simple. Create the main version of the app then add the package to the demo version and copy the main file there.

To run the demo version just change the package in the IDE "run settings".

Copy your codenameone_settings.properties to a separate file and just replace all the regular package names to the demo package names. When you want to build the "demo" version replace the codenameone_settings.propeties files with one another, you can automate that with a script obviously.
