Get user location in Android

Overview

Steps to follow

• Add the following permissions in AndroidManifest.xml file

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

• Add the following dependencies in gradle.build (Module) file

 implementation 'com.google.android.gms:play-services-location:19.0.0'

• Create a layout
• Write the logic

 private lateinit var fusedLocationProviderClient : FusedLocationProviderClient
 private val PERMISSION_ID = 44
 override fun onCreate(savedInstanceState : Bundle?)
 {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)
    fusedLocationProviderClient = FusedLocationProviderClient(this)
    getLastLocation()
 }

 @SuppressLint("MissingPermission")
 private fun getLastLocation()
 {
    if (checkPermissions())
    {
        if (isLocationEnable())
        {
            fusedLocationProviderClient.lastLocation.addOnCompleteListener {
                val location = it.result
                if (location == null)
                {
                    requestNewLocationData()
                } else

                }
            }
        } else
        {
            Toast.makeText(this , "Please turn on your location" , Toast.LENGTH_LONG).show()
            /*Intent is created to go to System Settings screen*/
