Android Tutorial Code: Get latitude OR longitude GPS and NETWORK in Android.

EXAMPLE : 1

Step 1: Add below dependency into your project.

implementation 'com.google.android.gms:play-services-location:18.0.0'

Step 2: Implement coding for the runtime permission for the location.

Step 3: Add below permission in to the android manifest.
<uses-permission android:name = "android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name = "android.permission.ACCESS_NETWORK_STATE" />
 Step 4: Below is the code spinet to get current location from the mobile.
class LocationHelper
{
    private val TAG = this.javaClass.name
    private var cancellationTokenSource = CancellationTokenSource()    

    fun getLocation(activity: Activity)
    {
        val fusedLocationClient = LocationServices.getFusedLocationProviderClient(activity)
        if (ActivityCompat.checkSelfPermission(activity,
     Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED
            && ActivityCompat.checkSelfPermission(activity,
     Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED)
        {
            return
        }

        val currentLocationTask: Task<Location> =  fusedLocationClient.getCurrentLocation(
PRIORITY_HIGH_ACCURACY, cancellationTokenSource.token)

        currentLocationTask.addOnCompleteListener { task: Task<Location> ->
            if (task.isSuccessful && task.result != null)
            {
                val result: Location = task.result                
                Log.i(TAG,"getLocation : (success): ${result.latitude}, ${result.longitude}")
            }
            else
            {
                val exception = task.exception
                Log.i(TAG,"getLocation : "+exception?.message!!)
            }
        }
    }
}

 Step 5: Call method.
LocationHelper.getCurrentLocation(activity)

EXAMPLE : 2

Here is one example which try to find location using GPS , if your GPS not available then try to use network for find location. GPS or Network not enable then it will ask user to Enable Gps/network Setting.
