I am planning to integrate Phunware map within Xamarin Forms app. I am able to create Android Binding project so I can get packages equivalent to Phunware Android native SDK. By this I am able to access all methods and classes of Phunware SDK. Now the challenge is I have to follow Phunware Android native sample app source code, write equivalent code in Xamarin Forms and bring the map. I have given Android UI xml and activity file for sample.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.phunware.java.sample.LoadBuildingActivity">
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/map"
android:name="com.phunware.mapping.MapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentEnd="true"
android:layout_alignTop="@id/map"
android:background="@color/white"
android:orientation="vertical"
android:padding="6dp">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/switch_floors" />
<Spinner
android:id="@+id/floorSpinner"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
</RelativeLayout>

@Override

super.onCreate(savedInstanceState);
setContentView(R.layout.load_building);
Spinner floorSpinner = findViewById(R.id.floorSpinner);
spinnerAdapter = new FloorAdapter(this);
floorSpinner.setAdapter(spinnerAdapter);
floorSpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
FloorOptions floor = spinnerAdapter.getItem((int) id);
if (currentBuilding != null && floor != null) {
currentBuilding.selectFloor(floor.getLevel());
}
}
@Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
// Create the map manager used to load the building
mapManager = PhunwareMapManager.create(this);
// Register the Phunware API keys
PwCoreSession.getInstance().registerKeys(this);
MapFragment mapFragment = (MapFragment) getFragmentManager().findFragmentById(R.id.map);
if (mapFragment != null) {
mapFragment.getPhunwareMapAsync(this);
}
}
@Override
public void onPhunwareMapReady(final PhunwareMap phunwareMap) {
// Retrieve buildingId from integers.xml
int buildingId = getResources().getInteger(R.integer.buildingId);
mapManager.setPhunwareMap(phunwareMap);
mapManager.addBuilding(buildingId,
new Callback<Building>() {
@Override
public void onSuccess(Building building) {
Log.d(TAG, "Building loaded successfully");
currentBuilding = building;
// Populate floor spinner
spinnerAdapter.clear();
spinnerAdapter.addAll(building.getBuildingOptions().getFloors());
// Set building to initial floor value
FloorOptions initialFloor = building.initialFloor();
building.selectFloor(initialFloor.getLevel());
// Animate the camera to the building at an appropriate zoom level
CameraUpdate cameraUpdate = CameraUpdateFactory
.newLatLngBounds(initialFloor.getBounds(), 4);
phunwareMap.getGoogleMap().animateCamera(cameraUpdate);
}
@Override
public void onFailure(Throwable throwable) {
Log.d(TAG, "Error when loading building -- " + throwable.getMessage());
}
});
}
}
Here, they are casting UI control to MapFragment and calling getPhunwareMapAsync() method. I just want to know in Xamarin Forms what control we can map to this MapFragment? In case we are about to write equivalent code in MainActivity of Xamarin Android project, how can we establish connection between PCL project and Android project and bring the map in View? I am just trying to figure out how to start and what to put where as I have excellent experience in Xamarin Forms but less experience with Android Native.
