Parameters description

Parameter	UI	Description	Default value
area_observation_duration	☐	Area observation duration period (in days)	365
sync	☐	Data synchronization settings (cf. https://github.com/PnX-SI/gn_mobile_core/tree/develop/datasync)
map	☐	Maps settings (cf. https://github.com/PnX-SI/gn_mobile_maps/tree/develop/maps)
input	☐	Input form settings
input/date	☐	Date settings
nomenclature	☐	Nomenclature settings
nomenclature/save_default_values	☐	Save default nomenclature values	false
nomenclature/information	☐	Information settings (as array)
nomenclature/counting	☐	Counting settings (as array)

Input settings

Allows to configure settings related to user input.

Date settings

How the user can set the start and end date of the input:

Parameter	Description	Default value
enable_end_date	Whether to edit as well the end date of the input	false
enable_hours	Whether to edit as well the hour part of the start and end date (if enabled)	false

The combination of these parameters gives the following configuration:

• enable_end_date and enable_hours are set to false: only the start date without the hour part is editable
• only enable_end_date is set to true: the start and end date without the hour part are editable
• only enable_hours is set to true: only the start date including the hour part is editable
• enable_end_date and enable_hours are set to true: the start and end date with the hour part are editable

If nothing is configured, only the start date without the hour part is editable.

Nomenclature settings

save_default_values: Allows to save locally and only during a session of use selected nomenclature values as default values (default: false).

Allows to define if fields are displayed by default and if they are editable (visible). If a field is not editable (visible), it will use the default value set in Occtax database.

All these settings may not be defined and the default values will then be used instead:

Information settings

Nomenclature	Label	Displayed by default	Editable (visible)
METH_OBS	Observation methods	true	true
ETA_BIO	Biological state	true	true
METH_DETERMIN	Determination method	false	true
determiner	Determiner	false	true
STATUT_BIO	Biological status	false	true
OCC_COMPORTEMENT	Behaviour	false	true
NATURALITE	Level of naturalness	false	true
PREUVE_EXIST	Proof of existence	false	true
comment	Comment	false	true

Counting settings

Nomenclature	Label	Displayed by default	Editable (visible)
STADE_VIE	Life stage	true	true
SEXE	Sex	true	true
OBJ_DENBR	Purpose of the enumeration	true	true
TYP_DENBR	Type of enumeration	true	true
count_min	Min	true	true
count_max	Max	true	true
medias	Medias	true	true

Note: Any unknown nomenclature attribute added will be simply ignored at startup.

You can override these default settings by adding a property for each nomenclature settings, e.g:

{
  "nomenclature": {
    "save_default_values": false,
    "information": [
      "METH_OBS",
      {
        "key": "ETA_BIO"
      },
      {
        "key": "METH_DETERMIN",
        "visible": true,
        "default": true
      },
      {
        "key": "STATUT_BIO",
        "visible": true,
        "default": false
      },
      {
        "key": "OCC_COMPORTEMENT",
        "visible": true,
        "default": false
      },
      {
        "key": "NATURALITE",
        "visible": true,
        "default": false
      },
      {
        "key": "PREUVE_EXIST",
        "visible": true,
        "default": false
      }
    ],
    "counting": ["STADE_VIE", "SEXE", "OBJ_DENBR", "TYP_DENBR"]
  }
}

Each property may be a simple string representing the nomenclature attribute to show or an object with the following properties:

Property	Description	Mandatory
key	The nomenclature attribute	☑
visible	If this attribute is visible (thus editable) or not (default: true)	☐
default	If this attribute is shown by default (default: true)	☐

Example:

• "METH_OBS" has the same meaning like

  {
    "key": "METH_OBS"
  }

  or

  {
    "key": "METH_OBS",
    "visible": true
  }

  or

  {
    "key": "METH_OBS",
    "default": true
  }

  or

  {
    "key": "METH_OBS",
    "visible": true,
    "default": true
  }

• An omitted property (e.g. METH_OBS) has the same meaning like

  {
    "key": "METH_OBS",
    "visible": false
  }

Upgrade git sub modules

Do NOT modify directly any git sub modules (e.g. commons, compat, mountpoint, viewpager and maps). Any changes should be made from each underlying git repository:

• commons: gn_mobile_core git repository
• compat: gn_mobile_core git repository
• datasync: gn_mobile_core git repository
• mountpoint: gn_mobile_core git repository
• viewpager: gn_mobile_core git repository
• maps: gn_mobile_maps git repository

./upgrade_submodules.sh

Troubleshooting

• Kotlin error, Redeclaration from class within imported module:

  clean project from menu Build -> Clean Project, then rebuild project.

Full Build

A full build can be executed with the following command:

./gradlew clean assembleDebug
