Discovere Nearest Caffe APP ( Near By Search )

Based on the location the user will be Discovere for the nearest Caffe through use the retrofit library to specify the request parameters and embed the place type and Latitude, Longitude within the request. and send it via Create a custom HTTP header. After that Send the GET HTTP request to the Google Place API server included with the API key to authenticate the request plus the customize HTTP header to get the server response via get nearby Caffe.

Setting up Project

Near By Search

Steps 5:

1. Setting up dependencies
2. Setting up permissions
3. Setting up view
4. Setting up networking with Retrofit
5. Cross check.

2.Setting up permissions

Android Manifest

     <uses-permission android:name="android.permission.INTERNET"/>
     <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
     <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>

3.Setting up view

Map

        <fragment xmlns:android="http://schemas.android.com/apk/res/android"
              xmlns:tools="http://schemas.android.com/tools"
              android:id="@+id/map"
              android:name="com.google.android.gms.maps.SupportMapFragment"
              android:layout_width="match_parent"
              android:layout_height="match_parent"/>

4.Setting up networking with Retrofit

Api service provider

            interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);

            Retrofit retrofit = new Retrofit.Builder().baseUrl(Constant.PLACE_API_BASE_URL).addConverterFactory(getApiConvertorFactory()).client(client).build();
            
            nearByApi = retrofit.create(NearByApi.class);
            return nearByApi;
        } else {
            return nearByApi;
        }
    }
    
    private static GsonConverterFactory getApiConvertorFactory() {
        return GsonConverterFactory.create();
    }
    
    
    public static MyApplication getApp() {
        return app;
