Eden Mobile is built on the [https://cordova.apache.org 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 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 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.: [https://developer.android.com/studio/index.html#downloads 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 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 [wiki:DeveloperGuidelines/EdenMobile/Debugging#RemoteDebuggingonAndroidDevice Remote-Debugging on Android Device]
 - Windows users may need to enable Powershell script execution in order to be able to run Cordova:
{{{
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
}}}
 - 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. [http://jshint.com 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/
[[BR]]However, many of our plugins require a minimum of Build.VERSION_CODES.M (i.e. Marshmallow)
