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 (9.0.0 currently):

npm install -g cordova 

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

3. If you want to build and test EdenMobile, you also need
   • Java JDK
   • an SDK for the target platform, e.g.: ​Android SDK
     • Configure as per ​https://cordova.apache.org/docs/en/latest/guide/platforms/android
     • 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
     • Ensure that ANDROID_HOME environment variable is set, e.g. for Windows 10:
       • %USERPROFILE%\AppData\local\android\sdk

4. You can fork/clone EdenMobile from here:

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

For some reason sqlite-native-driver.jar is not in the repo, so download from:

• ​https://registry.npmjs.org/cordova-sqlite-storage-dependencies/-/cordova-sqlite-storage-dependencies-2.0.0.tgz

& extract this to plugins\cordova-sqlite-storage\node_modules\cordova-sqlite-storage-dependencies\libs

5. Run the application

• You cannot 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 emulator you need to create an avd: android avd)
• 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)
• open Chrome's Developer Tools panel (More Tools menu) & then open Remote Devices inside that (More | Remote Devices | Inspect)
• Screenshots available here Remote-Debugging on Android Device
• NB You may need to manually Clear Storage on the device after install (even for brand new installs)
• NB Do NOT 'reconnect dev-tools' when reinstalling, close window & 'inspect' again, otherwise you will have lots of browser windows left open)

  cd eden_mobile
  npm install q-io
  cp default.config.xml config.xml # or <appname>.config.xml
  cordova platform add android
  cordova plugin add cordova-sqlite-storage # Reinstall needed for some reason (even though 'cordova plugin' shows it installed)
  # Needed on some platforms anyway, on others just to clear data, when-desired:
  adb uninstall org.sahanafoundation.eden_mobile # or org.sahanafoundation.eden_mobile.<appname>
  cordova run android # Builds apk & adb install platforms\android\build\outputs\apk\android-debug.apk
  

6. Accessing your developer PC's version of Sahana Eden.

Using Chrome Tools' Port Forwarding, you can redirect e.g. localhost:8000 on the Android device to localhost:8000 on your Developer PC when connected via USB. This allows you to use that in your Sync Settings.

• ​https://developers.google.com/web/tools/chrome-devtools/remote-debugging/local-server

7. ​jshint is a tool recommended to ensure Code Quality:

npm install -g jshint

Suggested .jshintrc attached (store in the folder just up from eden_mobile):

• http://eden.sahanafoundation.org/attachment/wiki/DeveloperGuidelines/EdenMobile/DevelopmentEnvironment/.jshintrc

8. Some developers may have problems with settings being retained even when uninstalled due to cloud backup (​https://developer.android.com/guide/topics/data/autobackup.html#EnablingAutoBackup), in which case adjust platforms/Android/AndroidManifest.xml:

   <application android:allowBackup="false"
   

9. Currently only Android 6.0 Marshmallow,or later, is supported. Configure the targeted platform in platforms/android/project.properties

   # 6.0 Marshmallow
   target=android-23
   

Cordova still supports down to 4.4 KitKat: ​https://cordova.apache.org/docs/en/latest/guide/platforms/android/
However, many of our plugins require a minimum of Build.VERSION_CODES.M (i.e. Marshmallow)
