/**
* An activity that displays an expandable list of items by binding to a data source implementing the ExpandableListAdapter, and exposes event handlers when the
* user selects an item.
* <p>
* ExpandableListActivity hosts a {@link android.widget.ExpandableListView ExpandableListView} object that can be bound to different data sources that provide a
* two-levels of data (the top-level is group, and below each group are children). Binding, screen layout, and row layout are discussed in the following
* sections.
* <p>
* <strong>Screen Layout</strong>
* </p>
* <p>
* ExpandableListActivity has a default layout that consists of a single, full-screen, centered expandable list. However, if you desire, you can customize the
* screen layout by setting your own view layout with setContentView() in onCreate(). To do this, your own view MUST contain an ExpandableListView object with
* the id "@android:id/list" (or {@link android.R.id#list} if it's in code)
* <p>
* Optionally, your custom view can contain another view object of any type to display when the list view is empty. This "empty list" notifier must have an id
* "android:empty". Note that when an empty view is present, the expandable list view will be hidden when there is no data to display.
* <p>
* The following code demonstrates an (ugly) custom screen layout. It has a list with a green background, and an alternate red "no data" message.
* </p>
*
* <pre>
* &lt;?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot;?&gt;
* &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
* android:orientation=&quot;vertical&quot;
* android:layout_width=&quot;match_parent&quot;
* android:layout_height=&quot;match_parent&quot;
* android:paddingLeft=&quot;8dp&quot;
* android:paddingRight=&quot;8dp&quot;&gt;
*
* &lt;ExpandableListView android:id=&quot;@id/android:list&quot;
* android:layout_width=&quot;match_parent&quot;
* android:layout_height=&quot;match_parent&quot;
* android:background=&quot;#00FF00&quot;
* android:layout_weight=&quot;1&quot;
* android:drawSelectorOnTop=&quot;false&quot;/&gt;
*
* &lt;TextView android:id=&quot;@id/android:empty&quot;
* android:layout_width=&quot;match_parent&quot;
* android:layout_height=&quot;match_parent&quot;
* android:background=&quot;#FF0000&quot;
* android:text=&quot;No data&quot;/&gt;
* &lt;/LinearLayout&gt;
* </pre>
*
* <p>
* <strong>Row Layout</strong>
* </p>
* The {@link ExpandableListAdapter} set in the {@link ExpandableListActivity} via {@link #setListAdapter(ExpandableListAdapter)} provides the {@link View}s for
* each row. This adapter has separate methods for providing the group {@link View}s and child {@link View}s. There are a couple provided
* {@link ExpandableListAdapter}s that simplify use of adapters: {@link SimpleCursorTreeAdapter} and {@link SimpleExpandableListAdapter}.
* <p>
* With these, you can specify the layout of individual rows for groups and children in the list. These constructor takes a few parameters that specify layout
* resources for groups and children. It also has additional parameters that let you specify which data field to associate with which object in the row layout
* resource. The {@link SimpleCursorTreeAdapter} fetches data from {@link Cursor}s and the {@link SimpleExpandableListAdapter} fetches data from {@link List}s
* of {@link Map}s.
* </p>
* <p>
* Android provides some standard row layout resources. These are in the {@link android.R.layout} class, and have names such as simple_list_item_1,
* simple_list_item_2, and two_line_list_item. The following layout XML is the source for the resource two_line_list_item, which displays two data fields,one
* above the other, for each list row.
* </p>
*
* <pre>
* &lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot;?&gt;
* &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
* android:layout_width=&quot;match_parent&quot;
* android:layout_height=&quot;wrap_content&quot;
* android:orientation=&quot;vertical&quot;&gt;
*
* &lt;TextView android:id=&quot;@+id/text1&quot;
* android:textSize=&quot;16sp&quot;
* android:textStyle=&quot;bold&quot;
* android:layout_width=&quot;match_parent&quot;
* android:layout_height=&quot;wrap_content&quot;/&gt;
*
* &lt;TextView android:id=&quot;@+id/text2&quot;
* android:textSize=&quot;16sp&quot;
* android:layout_width=&quot;match_parent&quot;
* android:layout_height=&quot;wrap_content&quot;/&gt;
* &lt;/LinearLayout&gt;
* </pre>
*
* <p>
* You must identify the data bound to each TextView object in this layout. The syntax for this is discussed in the next section.
* </p>
* <p>
* <strong>Binding to Data</strong>
* </p>
* <p>
* You bind the ExpandableListActivity's ExpandableListView object to data using a class that implements the {@link android.widget.ExpandableListAdapter
* ExpandableListAdapter} interface. Android provides two standard list adapters: {@link android.widget.SimpleExpandableListAdapter SimpleExpandableListAdapter}
* for static data (Maps), and {@link android.widget.SimpleCursorTreeAdapter SimpleCursorTreeAdapter} for Cursor query results.
* </p>

nRF Toolbox demonstrates how to implement the Bluetooth Smart features in an Android application.
It consists of number of profiles, like Heart Rate, Blood Pressure etc. that may be use as is to communicate with real devices.
They use the Bluetooth SIG adopted profiles, that may be found here: https://developer.bluetooth.org/gatt/profiles/Pages/ProfilesHome.aspx
The Template Profile has been created to give a quick start with implementing proprietary services. Just start modifying 4 classes inside
the template package to implement features you need.
Below you will find a short step-by-step tutorial:
1. The template consists of the following files:
- TemplateActivity - the main class that is responsible for managing the view of your profile
- TemplateService - the service that is started whenever you connect to a device. I handles the Bluetooth Smart communication using the...
- TemplateManager - the manager that handles all the BLE logic required to communicate with the device. The TemplateManager derives from
the BleManager which handles most of the event itself and propagates the data-relevant to deriving class. You don't
have to, or even shouldn't modify the BleManager (unless you want to change the default behaviour).
- TemplateManagerCallbacks - the interface with a list of callbacks that the TemplateManager can call. Each method is usually related to one
BLE event, e.g. receiving a new value of the characteristic.\
- TemplateParser - an optional class in the .parser package that is responsible for converting the characteristic value to String.
This is used only for debugging. The String returned by the parse(..) method is then logged into the nRF Logger application
(if such installed).
- /settings/SettingsActivity and /settings/SettingsFragment - classes used to present user preferences. A stub implementation in the template.
- /res/layout/activity_feature_template.xml - the layout file for the TemplateActivity
- /res/values/strings_template.xml - a set of strings used in the layout file
- /res/xml/settings/template.xml - the user settings configuration
- /res/drawable/(x)hdpi/ic_template_feature.png - the template profile icon (HDPI, XHDPI). Please, keep the files size.
- /res/drawable/(x)hdpi/ic_stat_notify_template - the icon that is used in the notification
2. The communication between the components goes as follows:
- User clicks the CONNECT button and selects a target device on TemplateActivity.
- The base class of the TemplateActivity starts the service given by getServiceClass() method.
- The service starts and initializes the TemplateManager. TemplateActivity binds to the service and is being given the TemplateBinder object (the service API) as a result.
- The manager connects to the device using Bluetooth Smart and discovers its services.
- The manager initializes the device. Initialization is done using the list of actions given by the initGatt(..) method in the TemplateManager.
Initialization usually contains enabling notifications, writing some initial values etc.
- When initialization is complete the manager calls the onDeviceReady() callback.
- The service sends the BROADCAST_DEVICE_READY broadcast to the activity. Communication from the Service to the Activity is always done using the LocalBroadcastManager broadcasts.
- The base class of the TemplateActivity listens to the broadcasts and calls appropriate methods.
- When a custom event occurs, for example a notification is received, the manager parses the incoming data and calls the proper callback.
- The callback implementation in the TemplateService sends a broadcast message with values given in parameters.
- The TemplateActivity, which had registered a broadcast receiver before, listens to the broadcasts, reads the values and present them to users.
- Communication Activity->Service is done using the API in the TemplateBinder. You may find the example of how to use it in the ProximityActivity.
3. Please read the files listed above and the TODO messages for more information what to modify in the files.
4. Remember to add your activities and the service in the AndroidManifest.xml file. The nRF Toolbox lists all activities with the following intent filter:
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="no.nordicsemi.android.nrftoolbox.LAUNCHER" />
</intent-filter>
5. Feel free to rename the nRF Toolbox application (/res/values/strings.xml ->app_name), change the toolbar colors (/res/values/color.xml -> actionBarColor, actionBarColorDark).
In order to remove unused profiles from the main FeaturesActivity just comment out their intent-filter tags in the AndroidManifest.xml file.
