Improving Data Integrity: Synchronization between EAM and ArcGIS Utility Netw...
Improving Data Integrity: Synchronization between EAM and ArcGIS Utility Netw...Safe Software Utilities and water companies play a key role in the creation of clean drinking water. The creation and maintenance of clean drinking water is becoming a critical problem due to pollution and pressure on the environment. A lot of data is necessary to create clean drinking water. For fieldworkers, two types of data are key: Asset data in an asset management system (EAM for example) and Geographic data in a GIS (ArcGIS Utility Network ). Keeping this type of data up to date and in sync is a challenge for many organizations, leading to duplicating data and creating a bulk of extra attributes and data to keep everything in sync. Using FME, it is possible to synchronize Enterprise Asset Management (EAM) data with the ArcGIS Utility Network in real time. Changes (creation, modification, deletion) in ArcGIS Pro are relayed to EAM via FME, and vice versa. This ensures continuous synchronization of both systems without daily bulk updates, minimizes risks, and seamlessly integrates with ArcGIS Utility Network services. This presentation focuses on the use of FME at a Dutch water company, to create a sync between the asset management and GIS.

- 3. Objectives Our goal here today is... ... to get familiar with the various Android UI elements ... to come to understand XML layouts ... to learn how to handle events within Android UIs
- 4. Activities and Tasks Activity somewhat akin to a web page or screen public class that extends android.app.Activity activities have event methods for override onCreate: activity "constructor" onDestroy: activity "finalizer" onStart/onResume/onPause/onStop/onRestart flow remember to always call up the inheritance chain
- 5. Activities and Tasks Tasks Tasks are the logical thread of use through Activities usually starting from the Home screen Tasks form a "back stack" of Activity instances "back" button removes the top card, destroys that activity Tasks are distinct from one another a new task creates a new stack of cards this means more than one Activity instance of the same type is possible Tasks cross applications and processes in this respect, Activities are like web pages
- 6. Viewables View and ViewGroups View is the base class for "widgets" ViewGroup is the base for Composite-patterned containers of other View objects (including other ViewGroup instances) Each Activity can hold one content View most often, this is a ViewGroup, forming a hierarchy Custom Views and ViewGroups you can do them, but it's pretty rare
- 7. Viewables Widgets (android.widget) "Push Me": Button, CompoundButton, CheckBox, ImageButton, RadioButton Text: EditText, TextView, NumberPicker, TextSwitcher Graphics: Gallery, ImageSwitcher, ImageView Selectors: RatingBar, SeekBar, Spinner, Switch Time: AnalogClock, DigitalClock, Chronometer, CalendarView, DatePicker, TimePicker Composite: ListView, SlidingDrawer, TabHost Media: MediaController Space (literally, just that--empty space!) ... and a few more
- 8. Viewables Layouts (android.widget) LinearLayout RelativeLayout TableLayout GridLayout AbsoluteLayout (bad!) FrameLayout (mostly useless!)
- 9. Viewables Dialogs (android.app) are a special case of Activity AlertDialog (OK/Cancel/Help, etc) ProgressDialog (56 of 100...) DatePickerDialog TimePickerDialog But Dialogs are not Activities Dialogs are always created and displayed as part of (and are "owned" by) an Activity; as such, they are intimately wrapped up in their host Activity's code AlertDialog is the workhorse here
- 10. Creation Two ways of creating UIs in Android either create UI "by hand" in Java or using XML-based layout (resource) file layout resources are not tied to an Activity; they are just a group of Views laid out in an XML file layout resources can be "inflated" from XML into UI objects (via a system service) Activity.setContentView() is a shortcut way to do this
- 11. Layout Resources Layout resources are in res/layout directory XML file name corresponds to R.layout.{filename} Root element is (usually) a ViewGroup (Layout class) android: namespace is mandatory element attributes describe "setter" values android:id is critical for manipulation "@+{prefix}/{name}" defines new R.{prefix}.{name} id {prefix} is most often "id" but isn't required IDs don't have to be unique across the entire tree (but usually are)
- 12. Layout Resources <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <ListView android:id="@+my_team_ids/lstInvitees" android:layout_width="fill_parent" android:layout_height="wrap_content" android:padding="6dip" /> <LinearLayout android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="fill_parent" android:gravity="bottom"> <TextView android:text="Add:" android:layout_width="wrap_content" android:layout_height="wrap_content" /> <EditText android:id="@+my_team_ids/txtNewTeamMember" android:layout_width="wrap_content" android:layout_height="wrap_content" android:hint="(Email address)" android:maxLines="1" /> <ImageButton android:id="@+my_team_ids/btnInvite" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@android:drawable/sym_action_chat" /> </LinearLayout> </LinearLayout>

Layout Resources Layout resources can be "tuned" like all resources, layouts can be spceialized to particular scenarios screen size: "small", "normal", "large", "xlarge" orientation: "port", "land" pixel density: "ldpi", "mdpi", "hdpi", "xhdpi", "nodpi", "tvdpi" platform version: "v3", "v4", "v7", ... this is one way to customize UI to different device profiles the above qualifiers MUST be in that order see ${SDK}/docs/guide/topics/resources/providing-resources.html
- 14. Menus Menus Activities can also have menubar items associated with them best used for actions that aren't common or frequent Menus are often defined in layout (res/menu) menu: define a menu, a container for menu items item: define a menuitem, with id, icon and title (text) group: convenience grouping of item elements (invisible)
- 15. Menus <menu xmlns:android="http://schemas.android.com/apk/res/android"> <item android:id="@+id/new_game" android:icon="@drawable/ic_new_game" android:title="@string/new_game" /> <item android:id="@+id/help" android:icon="@drawable/ic_help" android:title="@string/help" /> </menu>
- 16. Menus ActionBar (3.0+) A set of menus/menuitems appearing at the top generally only useful for tablets
- 17. Event-handling Most Views/ViewGroups offer events for code to subscribe to These are called "InputEvents" Most of the time, this is the classic "Listener" idiom View.OnClickListeners can be wired up in the XML layout Most of the time, these are wired up in onCreate()
- 18. Intents Moving from one Activity to another requires an Intent Intent = Action (verb) + Context (target) easiest Intent is the "launch the Activity" Intent Intent next = new Intent(this, NextActivity.class); startActivity(next);
- 19. Threading Good Thread hygiene is critical here This is a phone--you don't own the machine! Android isn't quite like Java, and has a slightly different "take" on the threads-and-UI position no blocking behaviors (in general) NO UI modifications from non-UI thread If the UI thread is inactive for more than 5 seconds, bye! Android provides Handlers, which can be sent Messages that will then be processed on the Activity's UI thread Java5 provides a few other constructs as well

- 21. Summary Android is a Java-based mobile device framework ... but it's not Java ... and it's not a web app technology ... and it's definitely not Swing or SWT
