How Can an Application Clearly show Far more POI Information to Consumers?



With the raising popularity of the mobile Net, mobile apps are now getting an integral element of our daily lives and deliver progressively a lot more varied features that deliver a lot of positive aspects to consumers. 1 these functionality is seeking for Level of Interests (POIs) or destinations, these kinds of as banks and eating places, in an application.

When a user queries for a POI in an app, other than common data about the POI, this kind of as the title and spot, they also assume to be shown other related information. For example, when looking for a POI in a taxi-hailing app, a consumer generally expects the application to screen both equally the searched POI and other close by POIs, so that the person can pick the most handy choose-up and drop-off position. When exploring for a bank department in a cellular banking app, a user generally wants the app to clearly show equally the searched lender branch and nearby POIs of a identical kind and their particulars these kinds of as business enterprise hrs, phone numbers, and close by roads.

Having said that, exhibiting POI aspects in an application is usually a problem for developers of non-map-linked applications, mainly because it demands a significant amount of detailed POI data that is generally challenging to obtain for most app developers. So, would not it be excellent if there was a support which an app can use to provide end users with information about POI (these as the business enterprise hours and scores) when they search for unique styles of POIs (this kind of as resorts, eating places, and scenic places) in the app?

Luckily, HMS Core Web page Kit gives a 1-halt POI look for services, which features far more than 260 million POIs in above 200 countries and locations all-around the entire world. In addition, the provider supports extra than 70 languages, empowering end users to search for destinations in their possess indigenous languages. The location detail lookup operate in the package makes it possible for an app to get details about a POI, such as the name, tackle, and longitude and latitude, dependent on the special ID of the POI. For illustration, a consumer can research for nearby financial institution branches in a mobile banking app, and watch facts about every single department, this sort of as their enterprise hours and phone quantities, or research for the location of a scenic place and see facts about close by accommodations and climate forecasts in a vacation app, thanks to the put depth research operate. The position element look for operate can even be utilized by area-based mostly video games that can use the operate to exhibit in-activity tasks and rankings of other gamers at a POI when a participant lookups for the POI in the sport.

The integration method for this package is simple, which I will display under.


The screenshot under can give you an impact on the spot detail research function.

Integration Method


Before receiving started out, you’ll require to make some preparations, these as configuring your application info in AppGallery Join, integrating the Web page SDK, and configuring the obfuscation configuration file.

If you use Android Studio, you can integrate the SDK into your task by way of the Maven repository. The goal of configuring the obfuscation configuration file is to reduce the SDK from being obfuscated.

You can comply with guidelines below to make appropriate preparations. In this article, I will never be describing the preparation techniques.

Creating Location Detail Search

Soon after producing related preparations, you will want to implement the spot depth look for purpose for getting POI specifics. The approach is as follows:

1. Declare a SearchService item and use SearchServiceFactory to instantiate the object.

When making a SearchService object, you want to move the Context parameter and API crucial. If you want to display an update wizard when HMS Core (APK) requires to be updated, you are encouraged to move the Context parameter of the Action sort. As for the API key, it is produced when you produce an app on the HUAWEI Developers web site. Take note that you want encode the API critical making use of the URLEncoder.encode(“Your apiKey“, “UTF-8”) technique.

2. Make a DetailSearchRequest object and set applicable parameters. 

The item will be made use of as the ask for physique for hunting for POI information. Applicable parameters are as follows:

  • siteId: ID of a POI. This parameter is necessary.
  • language: language in which look for results are displayed. English will be used if no language is specified, and if English is unavailable, the nearby language will be utilized.
  • young children: suggests regardless of whether to return details about little one nodes of the POI. The default price is bogus, indicating that little one node facts is not returned. If this parameter is set to legitimate, all data about baby nodes of the POI will be returned.

3. Develop a SearchResultListener item to pay attention for the research consequence.

4. Use the made SearchService item to get in touch with the detailSearch() strategy and go the produced DetailSearchRequest and SearchResultListener objects to the method.

5. Attain the DetailSearchResponse item making use of the made SearchResultListener item. You can attain a Web-site object from the DetailSearchResponse item and then parse it to attain the look for results.

The sample code is as follows:

// Declare a SearchService object.
non-public SearchService searchService 
// Generate a SearchService instance. 
searchService = SearchServiceFactory.generate(this, "
API essential
// Build a request physique.
DetailSearchRequest request = new DetailSearchRequest() 
// Create a research result listener.
SearchResultListener resultListener = new SearchResultListener()  
    // Return the lookup outcome when the lookup is prosperous.
    general public void onSearchResult(DetailSearchResponse outcome)  
        Site web site
        if (final result == null  
    // Return the consequence code and description when a look for exception happens.
    public void onSearchError(SearchStatus position)  
        Log.i("TAG", "Error : " + position.getErrorCode() + " " + standing.getErrorMessage()) 
// Contact the put depth search API.
searchService.detailSearch(ask for, resultListener)

You have now done the integration system and your application should be ready to show buyers specifics about the POIs they lookup for.


Cell applications are now an integral element of our each day existence. To strengthen consumer expertise and supply consumers with a far more convenient working experience, mobile applications are providing much more and additional features this kind of as POI lookup.

When searching for POIs in an app, apart from general data this kind of as the title and place of the POI, consumers usually hope to be shown other context-applicable details as nicely, these as enterprise hrs and comparable POIs close by. Having said that, displaying POI facts in an app can be difficult for builders of non-map-relevant applications, mainly because it necessitates a large total of specific POI data that is ordinarily tricky to obtain for most application builders.

In this report, I demonstrated how I solved this problem working with the area element lookup operate, which allows my app to display POI specifics to people. The complete integration procedure is clear-cut and cost-productive, and is an productive way to display POI details to users.
