Description of the work

The purpose of this project is to write a java class for use in the Android Studio environment (NOT ECLIPSE).

The class will have the task of interfacing with Google Place [1] and FuorSquare [2] APIs using a LOAD

BALANCING approach. The class should use ONLY FREE API CALLS. Therefore, it MUST NOT BE BASED ON


The java class to be developed will have to be structured using static methods, making the class NOT

INSTANTIABLE, NOR INHERITABLE. It is necessary that the class constructor raises an exception if you try to

instantiate the class itself. Also, you must correctly configure the non-heritability operators.

Types returned

The class shall use the following types of data.

1. Place is a class that contains all data returned by the Google API or the FourSquare API. In case

GoogleAPI and FoursquareAPI return fields with the same name, these names must be used as synonyms.

The place class must be provided with a DataOrigin field enhanced with "GoogleAPI" or "FoursquareAPI"

depending on the system that returned the information.

Methods to implement

The class, to be named PlaceAPI, must implement the following method:

- method getNearPlaces(Lat,Lng,radius): List(Of Place)

GetNearPlaces method

The getNearPlaces method interrogates the Google API or for the FourSquare API in BALANCE (it is the

responsibility of the author to balance calls) in order to exploit all FREE CALLS TO THE FREE API OF BOTH


Both systems accept input:

- current position (Latitude and longitude)

- a radius (radius)

Both systems (Google and FourSquare)provide a list of nearby Places of Interest. ALL PLACES RETURN from

calls to GooglePlace, or FoursquareAPI systems must be mapped to a Place class (a generic container

containing ALL SAMPLES returned by GoogleAPI and FourSquare API) highlighting the available fields and

leaving NULL those not available.


You must include the text "IREADTHEBRIEF" at the beginning of the freelancers' proposal, in order to

exclude any automatic offers.

The milestones will be released as described below:

1. The first milestone will be issued upon receipt of a working prototype. A working prototype is a java

class that meets the specifications given above (i.e. implements the interface and the required methods)

and that can be inserted in the ANDROID STUDY. This class will be submitted to AUTOMATED TEST by

ANDROID STUDY, through the automated A/D testing tool (which we provide).

2. The second milestone will be released upon receipt of the completed project. A completed project

means a java class that meets the above specifications and that has been corrected at the points

highlighted during the automated tests (in case of BUG or malfunctions.)
