Development Environment

Eden Mobile is built on the ​Apache Cordova platform (sometimes known as Adobe PhoneGap).

1. Cordova runs on NodeJS. If your OS distribution does not provide a NodeJS bundle, you can get one from here:

• ​https://nodejs.org/en/download

2. Use the NodeJS package manager npm to install Cordova:

npm install -g cordova 

See also: ​https://cordova.apache.org/#getstarted

3. If you want to build and test EdenMobile, you also need an SDK for the target platform, e.g.:

• ​Android SDK
  • Ensure the SDK tools are in your PATH, e.g. for Windows 10:
    • %USERPROFILE%\AppData\local\android\sdk\platform-tools
    • %USERPROFILE%\AppData\local\android\sdk\tools

4. You can fork/clone EdenMobile from here:

• ​https://github.com/sahana/eden_mobile

5. Run the application

• You canot run in the 'browser' platform as it doesn't support the local database
• It is easier to run on a real device than the emulator
• to run on a real device, you need to enable 'Developer Options' by tapping 7 times on the 'Build Number' in the About section (​http://www.greenbot.com/article/2457986/how-to-enable-developer-options-on-your-android-phone-or-tablet.html) and then open the new Developer Options panel & enable USB Debugging
  • see also: Remote-Debugging on Android Device
• to run on emulator you need to create an avd: android avd

  cd eden_mobile
  npm install q-io
  cordova platform add android
  adb uninstall org.sahanafoundation.eden_mobile # Shouldn't be required but can be for some systems
  cordova run android # Builds apk & adb install platforms\android\build\outputs\apk\android-debug.apk
  

6. Build for Release
   • Configure the default server, if-required: www/config/settings.js

     'url': {
             type: 'url',
             defaultValue: 'http://my.server.org/eden',
             writable: false,
     

   • @ToDo: Branding
   • create the non-debug APK

     cd eden_mobile
     cordova build --release android
     

   • File available as: platforms/android/build/outputs/apk/android-release-unsigned.apk

       # Generate Private Key (just once, outside the eden_mobile folder)
       # keytool comes with your JRE, so may need to ensure it's bin directory is in your PATH
       keytool -genkey -v -keystore my-release-key.jks -keyalg RSA -keysize 2048 -validity 10000 -alias my-alias
       # Optimise (zipalign comes with Android SDK build-tools, so may need to ensure it's in your PATH, e.g. %USERPROFILE%\AppData\local\android\sdk\build-tools\25.0.2)
       zipalign -v -p 4 android-release-unsigned.apk android-release-unsigned-aligned.apk
       # Sign (apksigner comes with Android SDK build-tools too)
       apksigner sign --ks my-release-key.jks --out android-release.apk android-release-unsigned-aligned.apk
