Google Maps Service

In java am trying to get Latitude and Longitude dynamically by passing the address.

GeoApiContext context = new GeoApiContext.Builder().apiKey("KEY") .build();

            String address = ""1600 Amphitheatre Parkway Mountain View, CA 94043";

            GeocodingResult[] results = GeocodingApi.geocode(context, address).await();

Added These two dependencies :

<dependency>

  <groupId>com.google.maps</groupId>

  <artifactId>google-maps-services</artifactId>

  <version>0.9.0</version>

</dependency>

<dependency>

  <groupId>org.slf4j</groupId>

  <artifactId>slf4j-simple</artifactId>

</dependency>

Note: There is no compilation error.

But AEM is not able to resolve these.

com.google.maps -- Cannot be resolved

com.google.maps.errors -- Cannot be resolved

com.google.maps.model -- Cannot be resolved

What all dependencies I need to add ?

I developed a small service with your Google MAP API code:

package com.adobe.aem.core;

import java.io.DataOutputStream;

import java.io.EOFException;

import java.io.File;

import java.io.FileInputStream;

import java.io.FileOutputStream;

import java.io.IOException;

import java.io.ObjectInputStream;

import com.google.maps.DirectionsApi.RouteRestriction;

import com.google.maps.DistanceMatrixApi;

import com.google.maps.DistanceMatrixApiRequest;

import com.google.maps.GeoApiContext;

import com.google.maps.GeocodingApi;

import com.google.maps.errors.ApiException;

import com.google.maps.model.DistanceMatrix;

import com.google.maps.model.GeocodingResult;

import com.google.maps.model.LatLng;

import com.google.maps.model.TravelMode;

public class MapImpl {

public String getLat()

{

try{

GeoApiContext context = new GeoApiContext.Builder().apiKey("KEY") .build();

        String address = "1600 Amphitheatre Parkway Mountain View, CA 94043";

        GeocodingResult[] results = GeocodingApi.geocode(context, address).await();

}

catch(Exception e)

{

e.printStackTrace();

}

return "" ;

}

}

I added the dependencies you mentioned. Then built this OSGi bundle as a Maven 13 Archetype project. This now goes into ACTIVE state

The key was to wrap the Google MAP JAR into an OSGi bundle and deploy. Now my service that uses the GOOGLE MAP API can go into Active state. So we have 2 OSGi bundles here:

If you do not know how to use an Eclipse Plug-in project to wrap a JAR into an OSGi bundle - follow these instructions in this article (we wrap simple JSON JAR as an example):

Dear Rodin,

Please add following instruction to your apache felix plugin configuration:

<Embed-Dependency>google-maps-services;inline=true </Embed-Dependency>

to your pom.xml file.

Regards,

Peter

Hi PuzanovsP​

Thanks for the response.

After making changes as you suggested. I am getting -->

okhttp3 -- Cannot be resolved

okio -- Cannot be resolved

com.google.appengine.api.urlfetch -- Cannot be resolved

To solve these I added below dependencies but still its not getting resolved.

<!-- https://mvnrepository.com/artifact/com.google.appengine/appengine-tools-api -->

<dependency>

    <groupId>com.google.appengine</groupId>

    <artifactId>appengine-tools-api</artifactId>

    <version>1.7.0</version>

</dependency>

<!-- https://mvnrepository.com/artifact/com.squareup.okio/okio -->

<dependency>

    <groupId>com.squareup.okio</groupId>

    <artifactId>okio</artifactId>

    <version>1.14.0</version>

</dependency>

<!-- https://mvnrepository.com/artifact/com.squareup.okhttp3/okhttp -->

<dependency>

    <groupId>com.squareup.okhttp3</groupId>

    <artifactId>okhttp</artifactId>

    <version>3.11.0</version>

</dependency>

OK,

Then you would need to work through the dependencies list and add dependencies that are relevant and needed for your code to run e.g.

<Embed-Dependency>appengine-tools-api,okio,okhttp,google-maps-services;inline=true </Embed-Dependency>

Note, there might be even more dependencies you would need to include. They will show up, once you include these ones.

Please add the one's that are needed for your code to run.

Another option is to get the JAR file from Maven - Maven Repository: com.google.maps » google-maps-services » 0.9.0

Then use an eclipse plug-in project to wrap that JAR into an OSGi bundle and deploy to AEM. This will ensure these packages are part of the OSGi service container.

Thanks for the response,

After adding (as google-maps-services is dependent on these 2 dependencies )-->

<dependency>

    <groupId>com.squareup.okio</groupId>

    <artifactId>okio</artifactId>

    <version>2.1.0</version>

</dependency>

<!-- https://mvnrepository.com/artifact/com.squareup.okhttp3/okhttp -->

<dependency>

    <groupId>com.squareup.okhttp3</groupId>

    <artifactId>okhttp</artifactId>

    <version>3.11.0</version>

</dependency>

I am getting-->

android.os -- Cannot be resolved

android.util -- Cannot be resolved

I am not sure why its showing android ?

Did you try to download the JAR and place it into an OSGi bundle and deploy that - i am going to see if this works or if this leads to only more dependency errors.

Dear Robin,

In your example you most likely want to avoid getting android libs. Therefore, you could add following rule:

<Import-Package>!android.os,!android.util, your other rules</Import-Package>

You need to look which part of google library you want to utilize,

Looking at functionality you want to use and configure Apache plugin to your needs[1]

I wrapped the Google API JAR into an OSGi bundle and it now exports these packages-

Can you post the full Java file with import statements of the code you are using. I will try to get it running in AEM

In my code I am trying to read an excel file and storing the data into nodes.

As in excel latitude and longitude is not available but address is there(city , street address, zip code). Here google API plays its role.

import Statements for google API:-

import com.google.maps.GeoApiContext;

import com.google.maps.GeocodingApi;

import com.google.maps.errors.ApiException;

import com.google.maps.model.GeocodingResult;

Code I am using to get Latitude and Longitude :-

            String address = fileImportModal.getAddress()+" "

                    +fileImportModal.getCity()+" "

                    +fileImportModal.getState()+" "

                    +fileImportModal.getZipCode();

 

            GeoApiContext context = new GeoApiContext.Builder()

                    .apiKey("KEY")

                    .build();

            GeocodingResult[] results =  GeocodingApi.geocode(context,

                    address).await();

            double latitude = results[0].geometry.location.lat;

            double longitude = results[0].geometry.location.lng;

          

            hcpNode.setProperty(RestoreConstants.DOC_LATITUDE, latitude);

            hcpNode.setProperty(RestoreConstants.DOC_LONGITUDE, longitude);

Thanks.
