 In this Android development related article, you will get a simple solution that, how to get address using Latitude, Longitude and vice-versa. i.e latitude, longitude from an address text. It is very easy and simple. Read full article and carefully follow all the steps. Here we use google Geocoder SDK. Okay, first we create an android project in kotlin and create an Activity say MainActivity.kt. Use the below code- Function get Latitude, Longitude from Address- fun getLatLngFromAddress (context: Context, mAddress: String): String { val coder = Geocoder(context) lateinit var address: List<Address> try { address = coder.getFromLocationName(mAddress, 5 ) if (address == null ) { return "Fail to find Lat,Lng" } val location = address[ 0 ] return " Latitude: ${location.latitude}\n Longitude: ${location.longitude}" } catch (e: Exception

 If we see the google play store android app, we can see that the app list in horizontal recycler view hold a property that the first property hold always full visible or not visible, but a portion visible is not seeing. This property is snap property. In this article I show you how to use it in our own application. Basically we use two type of snap. Center Snap and start snap. I show you both here. So read full article here. The Key Moment code is here- For center snap you need to write 2 lines code- //center Snap val snapHelper = LinearSnapHelper() snapHelper.attachToRecyclerView(recyclerView1) For start snap, create a class in kotlin say StartSnapHelper.kt package com.example.snaphelpersampleapp import android.view.View import androidx.recyclerview.widget.LinearLayoutManager import androidx.recyclerview.widget.LinearSnapHelper import androidx.recyclerview.widget.OrientationHelper import androidx.recyclerview.widget.RecyclerView class StartSnapHelpe
