Answer 1

I solved it myself by using another approach that is the new one used in the docs by developers.google.com. I used the first approach to add as an autocomplete widget.
on my activity's onCreate i initialised Places instance.
Places.initialize(getApplicationContext(), getResources().getString(R.string.google_maps_key));
PlacesClient placesClient = Places.createClient(activity);
again on my onCreate i initialised and declared my pickupFragment and bind it with a listener.
pickupFragment = (AutocompleteSupportFragment) getSupportFragmentManager().findFragmentById(R.id.pickupFragment);
pickupFragment.setCountry("PK");
pickupFragment.setPlaceFields(Arrays.asList(Place.Field.ID, Place.Field.NAME, Place.Field.ADDRESS, Place.Field.LAT_LNG));
pickupFragment.setOnPlaceSelectedListener(new PlaceSelectionListener() {
#Override
public void onPlaceSelected(Place place) {
// TODO: Get info about the selected place.
Log.e(TAG, "Place: " + place.getName() + ", " + place.getId() + ", " + place.getLatLng());
}
#Override
public void onError(Status status) {
// TODO: Handle the error.
Log.e(TAG, "An error occurred: " + status);
}
});
and used this piece of code in my xml
<fragment
android:id="#+id/pickupFragment"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:name="com.google.android.libraries.places.widget.AutocompleteSupportFragment" />
I did this for both my pickupFragment and dropoffFragment.
