How to Integrate Geolocation Services in Your Mobile App?

Android geolocation app is currently the talk, and you might be wondering how you can integrate the services on your Android or iOS phone. The as shown below, services help locate objects to help you assess the position of different users as shown in the image below. There are different processes you can follow to integrate the services on your mobile app.

Android location serivce

First, use LocationManager tools on your phone to assess and locate places. The LocationManager system service is the core component of location services. It provides a series of methods to deal with location-related issues, including querying the last known location, registering and deregistering periodic location updates from a LocationProvider, registering and deregistering proximity Triggering of a defined Intent at a certain coordinate, etc. It is recommended that you declare the foreground service type of location. In Android 10 (API level 29) and higher, you must declare this foreground service type. In Android 10 (API level 29) and higher, you must declare the ACCESS_BACKGROUND_LOCATION permission in your app's manifest to request background location access at runtime. On earlier versions of Android, when an app was granted foreground location access, it was automatically granted background location access as well.

Second, Obtain permissions (1) ACCESS_FINE_LOCATION is an accurate location. If you use GPS_PROVIDER or use GPS_PROVIDER and NETWORK_PROVIDER at the same time, you need to declare this permission, which is valid for both providers; Provides the most accurate estimate of the device's location as possible. If the location estimate comes from a LocationManagerService or FusedLocationProvider, the estimate is usually accurate to within 50 meters (160 feet), sometimes even within a few meters (10 feet). (2) ACCESS_COARSE_LOCATION is a rough location, and this permission is only for NETWORK_PROVIDER. This will provide an estimate of the device's location. If this location estimate comes from a LocationManagerService or FusedLocationProvider, the estimate will be accurate to within 3 square kilometers (~1.2 square miles).

Third, there are two ways to find the current coordinates of a handheld device, either by GPS, or a network based postionning. GPS always returns a very precise location while network based postionning has a margine of error to some extent.

What are the pros and cons?

There are not many tests have been done at present, and problems can be found, especially in some low-level OS versions. Mobile phones with old systems may not be able to obtain the location. It should be a system problem and this service has nothing to do with the network.

For example, this positioning has a big problem, that is, for some Android devices, when the location is obtained for the first time, it will be blocked at locationManager.requestLocationUpdates, causing the program to be stuck here, and the onLocationChanged callback cannot be obtained for a long time.

And as the test system becomes higher and more perfect, the best positioning method provided also has the option of hybrid positioning.

Since it is risky to only use LocationManager, it may not be possible to obtain the location, so what should I do?

Introducing Hybrid location system

In fact, the positioning API service SDKs of Google and ProfoneTracker are very good at present. Compared with relatively heavy functions such as map navigation, the positioning SDK is very small, and currently supports overseas positioning services. In addition some of the location services are free.

Since the LocationManager may not be able to obtain the location, we will add a third-party location service, such as Google location. We use both LocationManager and Google Location, whichever succeeds first.

Extend battery life

To prevent battery drain, set a reasonable timeout that stops location updates. Setting a timeout ensures that the update does not continue indefinitely and protects the application if the update is not removed after being requested (eg due to a code error).

For all non-foreground use cases, multiple requests are batched together. You can specify the time interval for calculating positions using the setInterval() method. Then use the setMaxWaitTime() method to set the time interval for the location to be passed to the application. The value passed to the setMaxWaitTime() method should be a multiple of the value passed to the setInterval() method.

It's great to integrate geolocation service into your apps as it will better interact with your users, however it's not without issues.

When we use network based location services such as WiFi and cell tower positioning it will solve the issue and provide way better experience.
